Kaoko Metals Limited (ASX: KAO)
Abstract
Kaoko Metals (ASX: KAO) listed on 7 May 2026 at 20 cents. On 2 September 2026 it closed at A$1.85, up 151.7% in one session, after reporting visual copper mineralisation in the first two diamond drill holes ever put into its Chalkos Copper-Silver Project in north west Namibia. DDOT002 logged 60.25 metres of visible copper from 36.65 metres down hole. DDOT001 logged 51.83 metres from 39.27 metres. Neither number is a grade. Both are estimates made by eye, and the company says so on almost every page of its own announcement. The shares went on to close at A$2.50 on 3 September and were then halted. On 7 September the company announced a A$20 million placement at A$2.20.
What has been established so far is narrow. Copper minerals are present, in core, at shallow depth, across several rock types, on ground that had never been drilled. Chalcocite, malachite, cuprite and native copper were all logged. Zones of mylonite sit alongside the strongest intervals, which supports the company's reading that structure as well as stratigraphy has focused the copper. That is a coherent geological story on a licence package of 39,033 hectares, one half of which has no recorded exploration of any kind.
The belt carries a testable metal ratio. The Kaoko Belt is a copper-silver belt rather than the copper-cobalt belt of Zambia and the Congo, and published work in the same district reports 0.4% to 5.2% copper with 23 to 312g/t silver. Okohongo, elsewhere in the same belt, carries an Inferred Resource of 7.7Mt at 1.55% copper and 26.77g/t silver. Where a copper grade and a silver grade in this belt have been reported for the same material, the ratio runs between roughly 14 and 23 grams of silver for every 1% copper. The Omatapati figures above are two separate ranges rather than paired assays, so no ratio can be taken from them. The window gives a reader a benchmark to check the pending assays against, and it is set out in Section 04.
Almost everything else remains unestablished. There is no Mineral Resource on either project, of any category. There is no economic study. True widths are unknown and both completed holes were collared from the same pad, so continuity is a hypothesis rather than an observation. The 69.6% copper headline grade comes from a hand-picked surface sample, one of just 35 ever taken, all of them on one of the two licences. Both Chalkos licences carried an expiry date of 30 June 2026 and renewal applications were still described as in process in September.
The market has repriced the company by roughly twelve times since listing, on announcements containing no laboratory data. The company's own September presentation puts its market capitalisation at listing at A$12.1 million. On all shares on issue after the placement, not just the shares that are quoted, it is capitalised at approximately A$174 million at the 3 September close, against more than A$24 million of cash. Samso puts no price on this company and could not defend one if we did. There is no dataset to build it from.
The placement is the second piece of evidence to arrive, and it is not a drilling result. It was priced at a 12.0% discount to the last close and a 20.2% premium to the fifteen-day average of A$1.83. The company reports new and existing long-only institutions and sophisticated investors in the book, without breaking it down. Cash goes from A$5.2 million to over A$24 million. A second diamond rig is named in the use of funds. Existing holders are diluted 13.0%. The placement shows how professional buyers priced the same incomplete information a reader is weighing. It says nothing about the grade the laboratory will report.
The argument is settled by one event. Assays from DDOT001 and DDOT002 are expected within four to six weeks of 2 September 2026. Visual logging often fails to survive the laboratory, and where that happens the share price correction is usually quick. Everything in this workup is provisional until those numbers land.
The call is WATCH & DYOR. The ground is scarce and the result is interesting. The price already assumes an answer to a question that has not been asked yet, so the four weeks before the assays arrive are the time to do the research.

Share price context. Kaoko traded between roughly 70 and 80 cents through late August, on volumes averaging under 330,000 shares a day. On 2 September it opened at A$1.30, traded as high as A$2.28, closed at A$1.85 and turned over 5.06 million shares worth A$9.06 million. That is more than fifteen times its four-week average volume in a single session. The following day it closed at A$2.50, and the shares were then halted pending the placement announced on 7 September. The stock is up more than twelve times its 20 cent issue price in four months. Every one of those moves rests on exploration news, none of it yet supported by a laboratory assay. |
1 WHY WE ARE DOING A FULL WORKUP ON THIS ONE
Kaoko Metals listed on 7 May 2026 at 20 cents. On 2 September 2026 it closed at A$1.85, up 151.7% in a single session, on an announcement that contained no assay results. Those two facts together are why we have written this workup.
What the company announced was visual copper mineralisation. Its geologists looked at the first two holes ever drilled at the Chalkos Copper-Silver Project and logged what they could see in the core. In DDOT002 they logged copper minerals over 60.25 metres. In DDOT001 they logged them over 51.83 metres. Neither number is a grade. Both are estimates made by eye, and the company said so, repeatedly and in bold, in the same document.
Samso does not usually write at this length about a company with no Mineral Resource, no economic study and no assays. We are doing it here for three reasons.
The first is that a first-ever drill programme intersecting broad, shallow copper mineralisation across a licence package that had never been drilled is a real geological event, whatever the grade turns out to be.
The second is that the market has already repriced the company by more than 150% on information that is explicitly incomplete. When a share price moves that far ahead of the evidence, the useful work is not to argue with the move. It is to set out precisely what is known, what is not, and what has to arrive for the price to be justified or unwound.
The third is that the underlying land position is genuinely underexplored in a way that is now rare. Before Kaoko, the entire recorded exploration history of the Chalkos Project amounted to 35 grab samples on one of its two licences. The other licence has no recorded exploration at all. That is unusual, and it cuts both ways.
Samso has not spoken with Kaoko Metals management in preparing this piece, and Kaoko Metals has not commissioned it, paid for it or seen it before publication. Everything here is drawn from the company's own public filings and from market data, both cited.
2 KAOKO METALS LIMITED - THE COMPANY AND THE STORY
Kaoko Metals Limited is a Perth-based exploration company with two projects in Namibia. It was incorporated on 13 June 2025, converted to a public company on 6 February 2026, and listed on the ASX on 7 May 2026 after raising A$6.5 million at 20 cents a share. The IPO closed oversubscribed at maximum subscription.
Figure 1. Kaoko Metals project locations. Chalkos is in the Kunene Region in Namibia's north west, roughly 400km west of Tsumeb and at about the same latitude. Karibib sits in the Erongo Region, roughly 130km west north west of Windhoek. The pink bands are the copper belts. Note the Midas Minerals (ASX: MM1) reference on the map, which is Kaoko's nearest listed analogue. Source: Kaoko Metals, ASX announcement 2 September 2026, Figure 7.
The two assets
Chalkos Copper-Silver Project sits in the Kaoko Belt in north west Namibia, held through two Exclusive Prospecting Licences, EPL 7608 and EPL 7943. An Exclusive Prospecting Licence, or EPL, is Namibia's exploration tenure. It gives the holder the sole right to explore a defined area for a fixed term. Kaoko owns 100% of both. Combined area is 39,033 hectares, which is 390 square kilometres. The company describes Chalkos as an 800 square kilometre project, and that figure does not reconcile with its own tenement schedule. See the discrepancies noted at the end of this section.
Karibib Gold-Copper-Tungsten Project sits in the Damara Belt in central Namibia, held through EPL 4663, covering 24,960 hectares. Kaoko does not own it. It holds a staged right to earn in, and on admission to the ASX it held no ownership interest at all. The structure is layered. Kaoko can earn up to 100% of Karibib Pegmatite Exploration, which holds 85% of Goas Pegmatite Exploration, which holds the licence. The effective ceiling is an 85% interest in the project.
Where the money is
Chalkos is the priority and the budget says so. The prospectus allocated A$1.5 million to A$1.87 million to Chalkos exploration in year one and A$1.48 million to A$1.78 million in year two. Karibib gets A$200,000 in year one and A$300,000 in year two, against A$400,000 of earn-in fees across the same period. On the company's own numbers, Karibib costs almost as much to hold as it does to explore.
After the June 2026 site visit the company reordered its own plan. Karibib was to be drilled first. Chalkos was moved ahead of it. The first two holes have since returned visible copper, though the decision itself was made on the strength of surface mapping rather than drilling, and the assays that would test it are still outstanding.
Market capitalisation, quoted shares against all shares
Most price screens will tell you Kaoko is a much smaller company than it is. That figure is calculated on quoted shares only. It excludes the 24.8 million shares held in ASX escrow, which are real shares with real economic ownership. They are simply not tradeable yet.
On all shares on issue the market capitalisation at the 3 September close of A$2.50 is approximately A$151.5 million, and the company uses the same figure in its September investor presentation. After the placement shares are allotted the same price gives approximately A$174.3 million. When you are comparing Kaoko to anything else, that is the number to use. Escrow falls from roughly 41% of the equity to 35.6% on the enlarged capital, and the first tranche, 11.57 million shares, comes free 12 months from issue. Anyone modelling the register needs that date in the calendar.
The overhang
Beyond the escrow there are 4.5 million options struck between 30 cents and 50 cents, all now deeply in the money at A$2.50, and 5.55 million performance rights issued to the vendors of Chalkos. The prospectus text we have been able to read does not set out the vesting conditions on those rights, which sit in a section of the document that was not available to us. That is a genuine gap and we say so rather than guessing. It is a reasonable question to put to the company. On a fully diluted basis the securities on issue at listing totalled 70,665,000. Adding the placement shares and the 2.25 million shares issuable under the Karibib earn-in takes the fully diluted count to 82,005,910.
The placement, and what it changes
On 7 September 2026 the company announced firm commitments for a A$20.0 million placement of 9,090,910 shares at A$2.20. Euroz Hartleys and Cumulus Wealth were joint lead managers and bookrunners. Settlement is expected on 14 September and the new shares are expected to begin trading on 15 September. No shareholder approval is needed. The issue uses 6,061,500 shares of placement capacity under ASX Listing Rule 7.1A and 3,029,410 under Listing Rule 7.1.
The issue price is a 12.0% discount to the last close of A$2.50 on 3 September. It is also a 20.2% premium to the volume weighted average price of A$1.83 over the fifteen trading days to that date. The issue price is above the fifteen-day average and below the last close. Both comparisons are set out here, and a reader can weigh which is the fairer reference. The company says the placement was supported by new and existing long-only global institutions and by sophisticated investors.
Samso's view is that the placement is the most useful piece of external evidence to arrive since listing. It is not a drilling result. Institutional, professional and sophisticated investors have put A$20 million behind core photographs and a belt argument, at a price a fifth above where the stock had been averaging, before a single grade has been reported. The company does not break the book down, so how much of it is institutional is not on the record. That does not show the copper is economic. It shows how a set of professional buyers priced the same incomplete information a reader of this workup is weighing.
The placement changes the balance sheet more than it changes the share price. Cash goes from A$5.228 million at 30 June to more than A$24 million before offer costs. On the June quarter's outgoings of A$775,000 that is years of funding rather than quarters, and it pushes the financing question well beyond the current programme. The company's stated use of funds is a second diamond rig at Chalkos, an expanded programme at Otniel and Donkey Hill, regional mapping, sampling and geophysics across the wider licence area, and geophysics at Karibib ahead of a maiden drill programme. The announcement calls that allocation a statement of current intentions that may change, and the presentation describes the second rig as still under investigation.
The cost is dilution of 13.0%. A holder who did not take part now owns 87% of the stake they held before, in a company with more than four times the cash and a larger drilling programme. Whether that trade was worth taking is a judgement, and it depends entirely on the assays.

3 THE ASSETS
Chalkos, and what the first two holes showed
On 2 September 2026 Kaoko reported the results of the first two diamond drill holes ever completed at Chalkos, both at the Otniel prospect. Diamond drilling recovers a solid cylinder of rock, called core, which can be logged, photographed and split for assay. It is the highest-fidelity way to sample a rock at depth, and it is more expensive and slower than the alternatives.
Figure 2. Drill hole location plan at Otniel. DDOT001 and DDOT002 were collared from the same pad, marked by the single orange dot. DDOT003 tests along strike, DDOT004 to the west and DDOT005 to the south. Note the mapped anticlines and synclines in blue, which is the fold architecture the company believes is helping to localise the copper. Source: Kaoko Metals, ASX announcement 2 September 2026, Figure 3.
Both holes were collared from the same pad. The company says this reflected site topography, water access and the state of the earthworks at the time, which had not yet caught up with the drill. That is a practical constraint rather than a design choice, and it limits how much the two holes can say about lateral continuity. They are, in effect, two angles from one point.
Figure 3. Cross section through DDOT001 and DDOT002 showing the logged intervals of visible copper mineralisation against schematic geology. The orange bars are visible mineralisation and the red bars are what the company calls strong visible mineralisation, meaning intervals where the estimated copper minerals are typically 5% or more by volume. The geology behind the holes is interpretation, not measurement. Source: Kaoko Metals, ASX announcement 2 September 2026, Figure 4.
Figure 4. Core from DDOT002 at 68.13m to 68.34m on the left, and DDOT001 at 64.03m to 64.17m on the right. In the left panel the company logs malachite, chrysocolla, cuprite and chalcocite. In the right panel it logs chalcocite, cuprite and dioptase, so the green there is dioptase rather than malachite. The lower image is core box 15 from DDOT002. This is what the market repriced on, and it is a photograph, not an assay. Source: Kaoko Metals, ASX announcement 2 September 2026, Figures 1 and 2.
The Managing Director put the result this way on the day of the announcement.
"While it is still early in the program and we are waiting for results of the initial assays, we are pleased to have observed broad zones of copper mineralisation in the first two holes at Otniel. DDOT002 intersected over 60m of predominantly malachite-chalcocite mineralisation, including a 32m zone of strong visible mineralisation, while DDOT001 returned over 51m of visible mineralisation including 17m of strong visible mineralisation." "This is a highly encouraging start to the first ever drilling of the 800km2 Chalkos Project, and we are excited to continue drilling at both the Otniel and Donkey Hill prospects." Gerard O'Donovan, Managing Director, Kaoko Metals, ASX announcement, 2 September 2026 |
That statement is carefully built. It leads with the caveat, it uses the word observed rather than intersected for the mineralisation itself, and it does not put a grade on anything. Read against the announcement it accompanies, it claims no more than the logging supports.
Two things in it are worth carrying forward. The 800 square kilometre figure does not match the company's own tenement schedule, which is discussed under discrepancies below. And the word encouraging is doing the work that the assays have not yet done.
How to read the result
There are four things in this announcement that a careful reader should weight, and two of them are genuinely encouraging.
The first encouraging point is depth. Continuous visible mineralisation starts at 36.65 metres in DDOT002 and 39.27 metres in DDOT001. That is shallow, and depth matters to the economics. If this system ever becomes a mine, mineralisation starting at 40 metres implies an open pit and mineralisation starting at 400 metres implies an underground operation.
The second is that the mineralisation is not confined to one rock type. It is logged across quartzite, conglomerate, siltstone and dolostone. Both holes also record zones of mylonite, which is rock that has been ground and stretched by deformation, sitting coincident with or immediately next to the strongest mineralisation. The company reads this as evidence that structure, meaning faults and shearing, helped focus the copper-bearing fluids alongside the favourable rock units. If that reading holds, the system is not restricted to a single bed and there is more room to hunt.
The third point is the one the company repeats in bold through its announcement. These are visual estimates. A geologist looking at a core and calling 6% malachite is estimating volume by eye. Malachite is about 57.5% copper by weight, chalcocite about 79.8%, cuprite about 88.8%. It is arithmetically tempting to turn a volume percentage into a grade. The company explicitly forbids it, and it is right to. Recovery, density, the proportion of the rock actually sampled and the accuracy of the eye all sit between the observation and the number. Assays are expected within four to six weeks of 2 September 2026.
The fourth is true width. Both holes report down-hole lengths only. The relationship between the drill orientation and the geometry of the mineralised zone is not yet established, and the company says so. A 60 metre down-hole interval could be a 60 metre true thickness or a much narrower zone cut at an unfavourable angle. Two holes from one collar cannot resolve that.
The distance from here to a Mineral Resource is large. The JORC Code prescribes no drill spacing for any confidence category. Classification is the judgement of the Competent Person, based on whether the data establish geological and grade continuity. Two completed holes from a single collar, with assays outstanding, cannot support a resource of any category, and the company has not suggested otherwise. The three holes that follow, from three separate collars, are the first that could begin to establish continuity.
"Visual estimates of mineral abundance or type should never be considered a proxy or substitute for laboratory analyses. Laboratory chemical assays are required to determine definitive mineral types, concentrations, or grades, which are the factors of principal economic interest." Kaoko Metals, ASX announcement, 2 September 2026 |
What was known at Chalkos before the drill arrived
Very little had been done, and that matters to the argument in both directions. The prospectus states that the only recorded exploration on the Chalkos Project was mapping and soil sampling by LexRox Exploration on EPL 7943. That work produced 35 grab samples in total across two phases. A grab sample is a hand-picked piece of rock. It is chosen because it looks interesting, which makes it useful for confirming that something is present and close to useless as a measure of average grade.
Those grab samples returned up to 52.7% copper at Otniel, up to 69.6% copper at Donkey Hill, and up to 31.97% copper in a later phase. The 69.6% figure appears on the front of the company's presentations. It is a correctly reported number, and it is a peak value from a hand-picked sample rather than an average.
On EPL 7608, which is 19,951 hectares of the 39,033 hectare project, the prospectus states that no exploration has been recorded at all.
Metallurgy has been tested at a preliminary level. XRT ore sorting, which separates rock by X-ray transmission, upgraded a 308kg Donkey Hill bulk sample from a 9.9% copper head grade to 13% copper, at a yield of 64% and a copper recovery of 82%. A 208kg Otniel sample went from a head grade the prospectus gives as either 3.0% or 3.5% copper to 8% copper, at a yield of 35% and a copper recovery of 61%. The recovery figures carry as much weight as the upgrade. Any sample can be upgraded by rejecting enough of it, so the copper lost to the reject stream is the number that tells a reader what the method costs. The Otniel figures do not reconcile with each other. At the stated yield and recovery the product would grade about 6% copper rather than 8%. The Donkey Hill set does reconcile. Both are quoted as published and the reconciliation is a question for the company. Acid leach testwork on samples grading 7.91% and 10.06% copper recovered 89% from one and 71.7% from the other. The company noted that the second sample showed high acid consumption, which it described as potentially prohibitive for commercial processing without treatment of the gangue, meaning the non-copper-bearing rock. That caveat sits in the prospectus and does not appear in the presentation.
Two limits on that testwork are worth stating, because neither is obvious from the headline recoveries. The mineralogy reported alongside it, in the company's investor presentation of 7 May 2026, is oxide, with brochantite, malachite and spangolite identified by X-ray diffraction, so what has been tested is weathered material. We can find no published results for primary sulphide in the prospectus or in any announcement to 2 September 2026, and sulphide is what a deposit of any depth would eventually have to treat.
The second limit is grade. The head grades tested run from about 3% to 10% copper. Okohongo's Inferred Resource in the same belt grades 1.55% copper. Recoveries measured on very high grade material do not tell a reader how ordinary resource-grade rock will behave, and the leach times behind these figures are not stated in the pages available to us. The size fractions are stated. The prospectus records the material crushed and screened to a p80 of minus 25mm, and the column work run on minus 2mm Otniel material.
What the September presentation adds at surface
The investor presentation released with the placement carries surface work that the 2 September drilling announcement did not. The company reports a new prospect at Chalkos called Bootless, where outcropping copper mineralisation has been mapped. It reports the mapped footprint at Otniel extended by up to 200 metres, taking it beyond 600 metres across multiple trends. At Donkey Hill it reports an extension of about 60 metres at Donkey Hill East, taking that footprint beyond 800 metres across three trends. It also describes 20 kilometres of confirmed strike on the belt with a further 20 kilometres of untested prospective ground along the same trend.
Every one of those figures is a mapped surface footprint or a company estimate, not drilling and not an assay. The same cautionary note the company applies to its core applies here. They do change the size of the target list. Donkey Hill carries the 69.6% surface grab sample and has not been drilled at all, and the company has now funded the rig time to test it.
The presentation gives the maiden programme as roughly 3,000 metres, already expanded at Otniel, and says the company is investigating the mobilisation of another diamond rig.
The area figures have moved, and the disclosure is now better than it was. The placement announcement describes the Chalkos licence area as approximately 400 square kilometres. That does reconcile with the 39,033 hectares in the tenement schedule, which is 390 square kilometres. The 800 square kilometre figure set out at the end of Section 02 has not been repeated. The presentation still carries 80,000 hectares in one place, which is the old 800 square kilometres in a different unit. So the company has corrected the figure in the announcement and not in the presentation. Both are reported here as published.
One statement in the presentation needs reading against Section 02. Chalkos is described as fully permitted for immediate drilling. Both Chalkos licences carried an expiry date of 30 June 2026 and the renewal applications were still described as in process in September. Both can be true at once, and the two belong side by side.

Karibib
Figure 5. The Karibib Project, EPL 4663, in the Erongo Region. The prospects sit along a north east to south west structural corridor described by the company as 20km long and 2km wide. Source: Kaoko Metals, ASX announcement 16 July 2026, Figure 1.
Karibib is a different kind of asset and a different kind of risk. It is a skarn and replacement system, meaning mineralisation formed where hot fluids from an intrusion reacted with carbonate rocks. It carries copper, gold, silver and tungsten. It sits in the Damara Belt, roughly 32km from the Navachab gold mine and about 40km from the Twin Hills deposit.
In May 2026 Kaoko took 54 rock chip samples across three prospects. Ten came back above 1% copper, three above 2% copper, and eleven above 0.1% tungsten trioxide. The strongest single result was sample Z2809 at 3.19% copper, 0.85g/t gold, 46g/t silver and 0.48% tungsten trioxide.
Historical work at Karibib is more extensive than at Chalkos, and the results were less encouraging. Gold Fields held ground there in 1983 and 1984 and let the licence lapse, having concluded the results did not warrant follow-up. Anglo American held it in 1988 and 1989, identified three areas with average gold values between 2 and 7 parts per billion, never followed them up, and allowed its licence to expire in 1990. The prospectus states plainly that the coordinates of both companies' sampling are unknown.
More recently, Arcadia Minerals drilled 10 reverse circulation holes for 551 metres in 2022. Reverse circulation drilling returns rock chips rather than solid core. It is faster and cheaper than diamond drilling and less precise. The two best intercepts were 4 metres at 1.35% copper and 0.68g/t gold from 24 metres, and 4 metres at 1.98% copper, 0.92g/t gold and 0.72% tungsten from 9 metres, reported by Arcadia as tungsten metal rather than as the tungsten trioxide used in Table 4. These are the numbers that appear in Kaoko's marketing. They are correctly reported, and both intercepts are only 4 metres wide.
The 2022 drilling was not done by Kaoko and no drilling has been done at Karibib since. The company has instead started a systematic regional geochemical programme, sampling soil and calcrete across the licence, which is the method Osino Resources used to find Twin Hills. That is a sensible sequencing decision. It is also two to three years of work before a drill target list of any confidence exists.
Tenure
Both Chalkos licences carried an expiry date of 30 June 2026. The company has submitted renewal applications for a further two-year term and told the market in September 2026 that it expects them to be processed in line with standard regulatory timelines. As at the date of this workup we have found no announcement confirming the renewals as granted, having read every Kaoko release listed on Market Index from admission on 6 May 2026 to 2 September 2026. Both Chalkos licences depend on that renewal. On the public record the position is pending, and resolving it sits with the company and the Namibian Ministry of Mines and Energy.
The prospectus also disclosed, in its risk section, that certain licence conditions attaching to the EPLs comprising the projects have not been strictly complied with, and that under the Namibian Minerals Act the Minister may cancel a licence where the holder fails to comply. The company said it was not aware of any such notice and considered the likelihood of forfeiture low. The underlying detail sits in the Title Report annexed to the prospectus.
At Karibib there is a separate access problem. The land use agreement for Farm Gamikaub terminated on 9 May 2021. Access is currently granted on an ad hoc basis by the landowner. The prospectus itself says this increases uncertainty and may disrupt systematic exploration unless the agreement is renewed or replaced.
There is also a live policy question. Namibia has a draft Minerals Bill contemplating mandatory local content and minimum Namibian equity participation. Earlier drafts referenced a 5% minimum. The prospectus notes that public discussion has included reference to potential requirements of up to 51% local ownership, and that if such requirements are imposed the company may be required to divest or dilute its interest in the projects. That is the company's own disclosure, not our speculation.
Discrepancies in the record
Two figures in the company's own documents do not reconcile, and Samso's practice is to state what is published, name the discrepancy and move on. Resolving it belongs to the company.
The prospectus refers in one place to a "large 80,000Ha land package". The tenement schedule in the same document lists 19,951 hectares plus 19,082 hectares for the two Chalkos licences, and 24,960 hectares for Karibib, totalling 63,993 hectares across all three.
The same gap appears in the announcements in different units. Kaoko describes Chalkos as an 800 square kilometre project. The two Chalkos licences total 39,033 hectares, which is 390 square kilometres. Both the 80,000 hectare and the 800 square kilometre figures are close to double the areas listed in the tenement schedule.
Separately, the same Otniel bulk metallurgical sample is given a head grade of 3.0% copper in one paragraph of the prospectus and 3.5% copper two paragraphs later.
4 THE KAOKO BELT AS A COPPER-SILVER SYSTEM
Kaoko's independent geologist notes in the prospectus that the Kaoko Belt shares similarities with the Central African Copperbelt but is not an exact analogue. One of the differences he lists is the metal association. The Zambian and Congolese deposits are dominantly copper-cobalt. The Kaoko Belt is dominantly copper-silver.
He presents that as a caveat. It also tells us what kind of deposit Chalkos is being tested for, and it gives us a metal ratio to check the pending assays against.
Figure 6. The Kaoko Belt in its regional setting. Chalkos sits in this belt, in the Kunene Region, roughly 43km from Sesfontein township. The belt is cut by named regional mylonite zones, the Purros (PMZ) and Three Palm (TPMZ) Cambrian shear zones, and by the Sesfontein Thrust (ST). That structural architecture is the context for the mylonite Kaoko logged in DDOT001 and DDOT002. The inset at top right places the Kaoko Belt alongside the Ghanzi-Chobe, Katanga and Zambezi belts, which is the Central African Copperbelt comparison the story rests on.

(2006), Miller (2008) and Webb (2013).
What a sediment-hosted copper deposit is
Chalkos is being explored as a sediment-hosted stratiform copper system, usually shortened to SSC. These are not deposits formed by a volcano or an intrusion pushing metal up from below. They form inside sedimentary basins, over long periods, and the mechanism is chemical rather than igneous.
The standard account is set out by Hitzman and co-authors in the Economic Geology centenary volume. Oxidised, salty groundwater moves through red sandstones and siltstones. Those red beds are red because the iron in them is oxidised, and oxidised brine passing through them strips out copper and carries it in solution. The brine keeps moving until it meets rock that is chemically reducing, typically a dark, organic-rich or pyritic shale or siltstone. At that boundary the chemistry flips, the copper drops out of solution, and it precipitates as sulphide. Geologists call that boundary a redox front.
Squire and Keays put the significance of these systems plainly. Sedimentary rock-hosted stratiform copper deposits are the world's second largest source of copper and the largest source of cobalt, and roughly 73% of that copper sits in just two basins, the Katangan Basin of the Central African Copperbelt and the Permian Basin that hosts Europe's Kupferschiefer. Their description of the process is the same one. Oxidised brines flush through the basin, and where the liberated copper reaches carbon-rich mudstone, the metals are deposited.
This matters for Kaoko because the company's own model at Chalkos is exactly that. In the JORC table appended to its 2 September 2026 announcement, the company describes copper concentrated in a dark grey to grey green phyllitic siltstone and shale, interbedded with dolomite of the Lower Omao Formation, sitting between the red beds of the Nosib Group below and the Omao carbonates above. It calls that unit the Chalkos Horizon and interprets it as the first and lowest redox boundary within the stratigraphic column. That is a standard description of a sediment-hosted copper target.
The United States Geological Survey published a formal deposit model for this class in 2015, by Hayes and co-authors, and it puts numbers on the fluid. The ore-forming brines were warm, between roughly 75 and 220 degrees Celsius, oxidised, and very saline, typically carrying more than 15 per cent sodium chloride equivalent. They moved upward across the bedding toward the host rocks. The reductant that stopped them was solid organic matter, petroleum or sour gas, or carbonised plant fragments, depending on the deposit subtype.
Figure 7. How a sediment-hosted stratiform copper system forms, drawn onto the stratigraphy Kaoko is targeting at Chalkos. The sequence is the same everywhere this deposit type occurs. An oxidised, saline brine strips copper from red beds, travels up-dip through permeable rock, and dumps its copper as sulphide where it meets a reducing horizon. Step three, the weathering overprint, happens hundreds of millions of years later and is discussed further down this section. Samso Research Media House original figure, built from the ore-system model of Hitzman et al. (2005) and Hayes et al. (2015), with stratigraphic names as used by Kaoko Metals. It is a schematic and is not drawn to scale. Nothing about the geometry at Chalkos has been established by drilling.

Basement at the base, then the Nosib Group, then the Beesvlakte and Devede Formations, with the stratiform copper marked in red at the top of the sequence. Compare the stacking order with Figure 7 above and with the Chalkos Horizon description in Kaoko's prospectus. The core photograph at right is massive chalcocite with malachite from 37 metres down hole, which is the same mineral pair and roughly the same depth Kaoko logged at Otniel.

The metal that comes with the copper
Sediment-hosted copper systems are not all the same and the difference shows up in what rides along with the copper. The Central African Copperbelt carries cobalt, and Cailteux and co-authors document that copper-cobalt character across the Congolese and Zambian deposits. The Kupferschiefer carries silver, and it carries a great deal of it.
The USGS deposit model sets out the pattern behind that. Hayes and co-authors record that 25 per cent of these deposits contain silver, grading between 2 and 200 grams per tonne, and 14 per cent contain cobalt, grading between 0.05 and 0.5 per cent in primary ore. They also record that silver is nearly totally confined to the zones bearing chalcocite and bornite, while cobalt extends into the pyritic zones. Deposits that carry by-product silver do not carry by-product cobalt, and the reverse holds as well, with the Kupferschiefer the only stated exception.
The Kaoko Belt being copper-silver rather than copper-cobalt therefore says something about which part of the mineral zonation a deposit occupies. Within this deposit class the two metal associations are close to mutually exclusive.
Figure 9. The sulphide zonation in a sediment-hosted copper system, and where the by-product metals sit within it. The sequence runs pyrite, chalcopyrite, bornite, chalcocite outward from the redox front. Silver rides with the copper-rich end of that ladder. Cobalt rides with the iron-rich end. Kaoko logged abundant chalcocite and only trace chalcopyrite in DDOT001 and DDOT002, which places what it has drilled so far at the silver-bearing end. Samso Research Media House original figure. Zonation sequence and the silver and cobalt distributions after Hayes et al. (2015), USGS Scientific Investigations Report 2010-5070-M.
The Kupferschiefer shows how large the silver side of such a system can be. The Polish Geological Institute reports Poland's anticipated economic copper resources in the Fore-Sudetic Monocline and North Sudetic Trough as 1,976 million tonnes of ore containing 36 million tonnes of copper and 107,000 tonnes of silver. That averages roughly 1.8% copper and roughly 54 grams per tonne silver. The same source records that since 2011 KGHM Polska Miedź has been the largest producer of silver worldwide.
The world's largest silver producer is therefore a copper miner, and the rock it mines is a sediment-hosted copper-silver shale. Silver in these systems can be a co-product carrying a material share of the revenue.
Exactly how the silver is held inside those copper minerals is still an active research question. Kelepile and co-authors examined that problem in the Kalahari Copper Belt, the other great Neoproterozoic copper-silver belt of southern Africa, in a 2020 paper on the partitioning and distribution of silver in sediment-hosted copper-silver deposits. We flag it as the reference work rather than summarising conclusions we have not read in full. For this workup the USGS statement is sufficient. The silver sits in the chalcocite and the bornite.
Figure 10 is the published version of that zonation, showing the mineral zoning of the Spar Lake copper deposit in Montana as mapped by the USGS. The sulphide list runs down the left and the mineral zones run across the top.
Figure 10. Mineral zones at Spar Lake. Stromeyerite, argentite and native silver appear in the red and orange columns, which are the chalcocite-chlorite and bornite-calcite zones. Cobaltite, cobalt-anomalous pyrite and nickel-rich pyrite appear in the blue and green columns, the galena-calcite and pyrite-calcite zones at the other end of the system. Silver sits at the copper-rich end and cobalt at the iron-rich end, within a single deposit. Stromeyerite is a copper-silver sulphide.

The Kaoko Belt's own silver record
Copper-silver mineralisation in the Kaoko Belt has been drilled, sampled and in one case estimated by other parties, on ground within a few hundred kilometres of Chalkos. That record is the closest evidence available for what Chalkos may contain.
The most directly relevant published science is a 2024 paper by Nghoongoloka and co-authors in Resource Geology, on the genesis of copper and silver mineralisation at the Omatapati prospect in the Opuwo district of the Kunene region. That is the Kaoko Belt, and it is the same administrative district as Chalkos. The paper reports mineralisation hosted in Neoproterozoic dolomite and argillite, with ore grades ranging from 0.4 to 5.2 weight per cent copper and 23 to 312 grams per tonne silver. It describes three hypogene stages involving calcite-quartz-barite veins carrying chalcopyrite and bornite, and it concludes that Omatapati represents a sediment-hosted copper-silver deposit similar to those in the Central African Copperbelt.
The counterweight belongs in the same paragraph. The authors report fluid inclusion temperatures of 145 to 300 degrees Celsius and interpret magmatic fluids mixed with meteoric water or seawater, and the mineralisation they describe sits in veins. That is a hotter and more hydrothermal picture than the low-temperature basinal brine model Kaoko applies at Chalkos. The paper supports the belt carrying copper-silver mineralisation of this family. It does not confirm that Chalkos formed by the same process.
The stratigraphic position is similar at both prospects. The authors place the Omatapati mineralisation in the Devede Formation, sitting above the Beesvlakte Formation, which sits above the Nosib Group, which sits on basement. Kaoko puts its Chalkos Horizon in a comparable position, between the red beds of the Nosib Group below and carbonates above. The two descriptions were made independently.
Further east, the Okohongo deposit has been drilled repeatedly. INV Metals reported hole INVR-037 returning 31 metres at 1.8% copper and 40.6g/t silver, and an earlier hole 6 returning 45 metres at 2.0% copper and 27.1g/t silver. In 2021 White Metal Resources filed a technical report with an Inferred Mineral Resource of 7,706,732 tonnes at 1.55% copper and 26.77 grams per tonne silver, at a 0.30% copper cut-off, containing 119,256 tonnes of copper and 6,634,133 ounces of silver.
Midas Minerals reported its maiden Inferred Resource at Otavi as 10.5 million tonnes at 1.6% copper and 21 grams per tonne silver.
One more piece of context before the tests. The USGS compiled grade distributions for 135 sediment-hosted copper deposits worldwide, and the silver one is reproduced below. It shows the proportion of deposits carrying more than a given silver grade.
Figure 11. Silver grades in sediment-hosted copper deposits worldwide, from a population of 135. The curve starts at roughly 0.27. The curve starts at roughly 0.27, so only about a quarter of these deposits carry meaningful silver at all, which matches the 25 per cent the USGS deposit model states. And the marked line sits at 30 grams per tonne against a proportion of 0.10, so only one deposit in ten anywhere in the world exceeds 30 grams per tonne silver. Reproduced from Cox, Lindsey, Singer, Moring and Diggles (2003), Sediment-hosted copper deposits of the world, USGS Open-File Report 03-107, Figure 3.
Against that distribution, Okohongo's Inferred Resource of 26.77 grams per tonne silver sits just under the line marking the global top tenth. Omatapati's reported range of 23 to 312 grams per tonne would put much of it beyond that line. On these published numbers the Kaoko Belt's silver tenor is high by world standards for this deposit type.
Whether Chalkos does the same is not yet known. The 2 September 2026 announcement reports copper minerals only, with no silver in its logging table and no silver assay data, and the word silver appears in it solely in the project name and in boilerplate. So nothing Kaoko has published tells us whether its copper carries silver at Okohongo's tenor, at a fraction of it, or at all. We assume the core is being assayed for silver, because the project is named Copper-Silver and the belt carries it. That is an assumption rather than a fact. We also do not know what weight management places on silver, or whether it is treated as a target in its own right.
What this gives a reader before the assays land
Three things, and they are all testable within weeks.
First, is there silver at all. If the DDOT001 and DDOT002 assays return copper with little or no silver, then whatever Chalkos is, it is behaving differently from the systems the belt has produced everywhere else it has been drilled. That would not make the copper worthless. It would materially weaken the belt-analogue argument that underpins the whole story, and it would remove a revenue stream the market is currently assuming.
Second, the ratio. Where a copper grade and a silver grade in this belt have been reported for the same material, the ratio runs between roughly 14 and 23 grams of silver for every 1% copper. Okohongo's Inferred Resource is at about 17, and its two published intercepts are at about 23 and about 14. Omatapati is not in that count. Its copper and its silver are published as two separate ranges rather than as paired assays, so a ratio cannot be taken from them. Outside the belt, the Otavi resource is at about 13 and the Polish Kupferschiefer averages about 30. If Chalkos lands inside the belt window, the case that it is the same kind of system gets a great deal stronger, whatever the absolute grade. If it lands far outside it in either direction, that is a question worth asking the company.
Third, whether the silver tracks the chalcocite. The USGS model says silver in these deposits is nearly totally confined to the chalcocite and bornite zones. Kaoko logged chalcocite at 5% to 8% through DDOT002's strongest interval, from 59.30 to 91.66 metres. That is a specific, checkable prediction. If the silver assays peak in those same metres, the mineralogy and the geochemistry are telling the same story and the deposit model is behaving. If the silver is somewhere else entirely, or absent where the chalcocite is thickest, something in the model does not fit and it is worth finding out what.
A caution on the shallow copper
The same literature carries a caution about core descriptions of this kind. Readers should understand that the results, and what they imply about the system, may still end up as a disappointment without being technically wrong.
The Omatapati paper describes a supergene process producing a semi-massive chalcocite and covellite zone extending from surface to roughly 50 metres depth. Supergene means secondary, formed by weathering. Rainwater works down from surface, dissolves copper from the primary rock, carries it lower and redeposits it as a concentrated blanket. It creates a zone that is richer than the rock beneath it and shallower than the rock that made it.
Kaoko logged malachite, azurite, chrysocolla, cuprite, native copper and chalcocite, from 36.65 metres to 96.90 metres down-hole in DDOT002. At dips of 55 and 65 degrees, that down-hole window is roughly 30 to 80 metres of true vertical depth, which is the depth range Omatapati's supergene blanket occupies.
One point of care is needed here, because chalcocite by itself does not settle the question. Figure 10 shows chalcocite as the innermost primary zone of an unweathered deposit, and it is also the classic mineral of supergene enrichment. It occurs both ways. The other minerals logged alongside the chalcocite point toward weathering. Malachite, azurite and chrysocolla are copper carbonates and silicates formed at surface conditions, and cuprite and native copper belong to the same environment. That assemblage, at this depth, is the signature of a weathering profile rather than of the primary system.
Figure 12. Supergene copper minerals under the microscope, from the Kaoko Belt. In panel (a) the basket weave textures are chalcocite, digenite, delafossite and hematite replacing chalcopyrite, which is the primary sulphide being broken down and reformed as secondary minerals. Panel (b) is semi-massive covellite. Panels (c) and (d) show stockwork chalcocite with malachite, goethite and hematite. Cct chalcocite, Dg digenite, Cv covellite, Ccp chalcopyrite, Mal malachite, Del delafossite, Hem hematite, Goe goethite, Brt barite, Qtz quartz, Wul wulfenite. Reproduced from Nghoongoloka et al. (2024), Resource Geology 74(1) e12341, Figure 10.
The company itself points at this. It notes trace chalcopyrite within brecciated clasts in the shear fabric, and describes that as giving an indication of the primary mineralisation at depth. Chalcopyrite is the primary sulphide. Its scarcity in these holes, against abundant chalcocite and copper oxides, is consistent with the drill having tested the weathered upper part of a system rather than its core.
Figure 12 shows that process under a microscope, from the same belt. In panel (a) the chalcopyrite is being replaced by chalcocite, digenite, delafossite and hematite. The copper in that rock was not deposited there by the ore-forming fluid. It was moved and reconcentrated upward by weathering. The Omatapati authors also report sulphur isotope values for the supergene chalcocite and covellite averaging plus 9.1 per mille, distinctly heavier than the primary sulphides in the same system, which is a second line of evidence that the shallow material has a different origin from the rock below it.
None of this counts against the result. Supergene enrichment is real copper, it is shallow, and shallow material is generally cheaper to mine than deep material. Kaoko's own preliminary leach testwork was done on oxide material. It does limit what the first two holes can prove. A rich weathered blanket indicates that a copper system exists beneath it. It says much less about the size or grade of that system at 200 or 400 metres, which is the depth at which a deposit of any scale would have to sit.
Structure and the belt's mylonite zones
One last piece of belt geology. Both Kaoko holes record mylonite, meaning rock ground and stretched by ductile deformation, sitting coincident with or immediately next to the strongest visible mineralisation. The company reads that as structure helping to focus copper deposition. The regional literature makes that a reasonable reading rather than a hopeful one. Goscombe, Hand and Gray describe the Kaoko Belt as a classic transpressional orogen, meaning a belt built by simultaneous squeezing and sideways sliding, which is precisely the setting that generates pervasive ductile shear fabric.
Figure 6 shows the scale of that deformation. The belt is divided into five tectonostratigraphic zones and the dividers are themselves named and mapped mylonite zones. Nghoongoloka and co-authors describe the Three Palm and Purros mylonite zones as Cambrian shear zones with an apparent age of 492 to 467 million years, alongside the Sesfontein Thrust. Chalkos sits within that architecture, so sheared rock in a Kaoko Belt drill hole is a common feature rather than a finding in itself. Reading it as a positive control on mineralisation remains a hypothesis that the assays will begin to test.
Deformation can work in either direction. It can open pathways and concentrate metal, which is the reading the company offers. It can also smear, thin and dismember a stratiform layer that was originally continuous, which would help explain why a belt this prospective has produced so few deposits of size. Both readings are consistent with what has been logged so far, and only further drilling will separate them.

5 THE MACRO AND THE COMMODITY BACKDROP
Copper traded at US$6.52 per pound on 2 September 2026, up approximately 43.6% over twelve months. That price is what makes a Namibian exploration story fundable, so it sits behind everything else in this workup.
The structural argument for copper is now well rehearsed and largely correct. Electrification, grid rebuilds, electric vehicles and data centre construction are all copper-intensive. Supply is constrained by ageing mines with falling head grades, by a long period of underinvestment in greenfield exploration, and by development lead times the industry itself puts at well over a decade. Kaoko's prospectus cites S&P Global for a lead time averaging 17 years.
Kaoko's own market section quotes demand rising from roughly 28 million tonnes in 2025 to 42 million tonnes by 2040, supply peaking near 27 million tonnes around 2030 before declining toward 22 million tonnes by 2040, and a potential structural shortfall of up to 10 million tonnes a year by 2040. Those are third-party numbers from S&P Global, Baker Steel and Fastmarkets. The prospectus discloses, against each of them, that the author has not provided consent for the statement to be included. That is a standard mechanism, and it means the numbers arrive without the author standing behind their use in that document.
The macro is best treated as a tailwind rather than as the investment case. A rising copper price lifts every copper explorer's ability to raise money and every copper explorer's share price. It does not make a particular 40 metre interval of malachite economic. If the copper cycle turns, the September placement has bought Kaoko time that most explorers at this stage do not have. The company still has no revenue and no facilities, so a long enough downturn would eventually reach it.
Silver and tungsten sit alongside as credits rather than drivers. Silver credits at Chalkos are real, with 2,030g/t reported in surface sampling. Tungsten at Karibib is interesting because Western supply is thin, but at 0.68% tungsten trioxide from a dump sample it is a long way from being a business.
6 HOW KAOKO COMPARES WITH ITS PEERS
Section 02 set out what the market is paying for Kaoko today. This section asks a different question. Is roughly A$174 million a normal price for a company at this stage, a high one, or a low one? The only way to answer that is to look at what the market pays for other listed explorers doing similar work on similar ground.
Market capitalisation is the share price multiplied by every share on issue. It is what the market says the whole company is worth. For an explorer with no revenue and no mine, it is close to a pure statement of what investors think the ground might one day be worth, discounted for the chance that it never gets there.
The peer set, and why these companies
Eight companies are compared below. Three are the other ASX-listed copper explorers working in Namibia, which is the closest available comparison on geology and on country. Two work the Kalahari Copper Belt in Botswana, the other large sediment-hosted copper province in southern Africa. Two are ASX-listed copper explorers at a similar stage in South America, included so that jurisdiction is a variable in the table rather than a constant. Kaoko itself is the first row.
Jurisdiction, and the evidence each company is standing on
Jurisdiction risk is the risk that the country changes the rules. Samso's view is that it deserves more weight than investors usually give it. Attention naturally goes to the grade, the market capitalisation and the newsflow. An explorer has none of those without its licence. An exploration licence is a promise from a government and nothing else until a mine is built, so the things that sit outside an ordinary investment checklist are the things that decide whether an explorer still has a project next year. The table below shows what that means for Kaoko.
What the comparison shows
Five of the seven peers sit between roughly A$7.7 million and A$24 million. Four of the five are drilling with no Mineral Resource at all. The fifth, Golden Deeps, says it holds resources but does not publish figures we were able to check. That band is where the explorers in this sample have traded through 2026. It is seven companies, not a survey, so it indicates a range rather than establishing one.
Kaoko is at roughly A$174 million after the placement. Against that band it is priced at something like seven to twenty-three times its stage peers, on the strength of two holes whose assays have not been returned. Noronex is the sharpest single comparison in the table. It is a copper-silver explorer, in Namibia, drilling, with no company-held resource, and the market values it at about A$7.7 million. That quote had not moved in a session, so the stock is thinly traded and the figure should be read as approximate.
Figure 13. Market capitalisation of Kaoko against the seven listed peers in Table 7. The shaded band is the A$7.7 million to A$24 million range in which five of the seven sit, all of them drilling and none with a Mineral Resource it can point to, except Golden Deeps whose claim we could not check. Kaoko is the orange bar, shown at its 3 September 2026 close on all shares on issue after the 7 September placement. The two bars above it are the only companies in the set that have something measured behind them, a JORC Inferred Resource at Midas and a producing mine at Cobre. The figures are not struck on the same day and each is dated in Table 7. Source: Samso Research Media House original figure, built from the figures and sources in Table 7.
The two large numbers in the table mark the other end. Midas at roughly A$324 million has a defined 10.5 million tonnes at 1.6% copper. Cobre at roughly A$423 million is producing copper cathode in Chile. Both show what a re-rating looks like when it is attached to something measured. Midas is the nearer case, and its resource was estimated on drilling done before Midas owned the ground rather than on its own campaign. Midas has itself re-rated sharply over the past twelve months. Its shares have traded between 35 cents and A$1.41 in that period, which is the kind of range this cohort moves through in both directions.
There is a counterweight. Kaoko holds 39,033 hectares of the Kaoko Belt outright, one half of which carries no recorded exploration of any kind, on a belt with a demonstrated copper-silver endowment set out in Section 04. Scarcity of untested ground in a proven belt is worth something, and part of Kaoko's premium is that.
The scarcity argument does not hold as a general claim, and Vantage Metals is why. Vantage began maiden drilling in July 2026 on roughly 3,900 square kilometres of Kalahari Copper Belt ground in Botswana, held outright with no partner. That is about ten times Kaoko's 390 square kilometres, in a belt that already hosts a producing copper mine at Khoemacau. Vantage is capitalised at roughly A$13.5 million. Kaoko is capitalised at roughly thirteen times that.
Part of the argument still stands, and it turns on which belt each company is in. Chalkos sits in the Kaoko Belt on the same stratigraphy as Okohongo, which carries 7.7 million tonnes at 1.55% copper and 26.77 grams per tonne silver, and near Omatapati, which is the subject of the published work set out in Section 04. Kaoko's ground is untested but its belt is not. Vantage's Botswanan ground is along strike from a producing mine at Khoemacau, which is the same kind of argument, so this narrows the gap between the two companies rather than closing it.
What separates the two companies is a single piece of evidence. Kaoko has copper minerals in core and has told the market about it. Vantage has drilled targets defined by airborne electromagnetic and magnetic surveying. We searched its announcements and its coverage to 3 September 2026 and found no reported intercept, visual or assayed, from that programme. Both are at the same formal stage, which is drilling with no Mineral Resource. Kaoko's market capitalisation is roughly A$161 million above Vantage's. More than A$24 million of that is cash the placement raised, so on enterprise value the gap is closer to A$137 million. That gap rests on the one difference in evidence, together with the belt argument above, before any assay has confirmed either. The assays will settle it.
Where this comparison breaks down
Three limitations apply, and each one argues for reading the table loosely.
The market capitalisations are not struck on the same day, and in a sector this volatile that matters. The oldest figure in the table is Noronex at 23 July 2026 and the newest are dated 3 September. A single announcement can move any of these companies by half in a session, as Kaoko itself demonstrated on 2 September.
Five of the seven peers are not pure copper companies. Golden Deeps carries eight metals, Noronex has moved capital into uranium, Mammoth has been expanding into gold, Vantage holds zinc and gold ground in Australia and Argentina alongside its Botswanan copper, and Cobre's market capitalisation is dominated by a producing Chilean mine rather than by its Botswanan exploration. Their market capitalisations are not clean copper-exploration numbers, and Kaoko's is not either, since it includes Karibib.
Stage is not a single axis. A company drilling its first hole into untested ground and a company drilling its fiftieth into a known deposit are both described as drilling, and they are not the same proposition. The table separates resource from no resource because that is the one boundary the JORC Code makes objective. Everything on the no-resource side of that line is a matter of judgement.
7 VALUATION, OUR OWN WORKING
This is a Track B piece. There is no economic study, no Mineral Resource of any category, and no assay data from the current drilling. Samso puts no price on this company, and would not be able to defend one if we did.
What we can do is set out what the market is currently paying for, and what it is comparing the company to.
What the market is paying for
At the 3 September close of A$2.50 the market is valuing Kaoko at roughly A$174 million on all shares on issue after the placement, against more than A$24 million of cash and two projects with no defined resource. That leaves an enterprise value of roughly A$150 million, on Samso's own arithmetic. The company's September presentation gives its market capitalisation at listing as A$12.1 million, against approximately A$151 million at 3 September before the placement. On the same published figures the market capitalisation has moved by roughly twelve times in four months, and by roughly fourteen times once the placement shares are counted at the same price.
It has done so on one announcement containing no assays. That does not make the move wrong. Exploration repricing is often front-run, and by the time assays confirm a discovery the entry price has usually gone. It does mean the risk profile has changed. A buyer in May was paying very little for the geology. A buyer in September is paying mainly for it.
The comparable the company itself uses
Kaoko's own material points repeatedly at Midas Minerals (ASX: MM1) and its Otavi Project. Midas reported a maiden Inferred Resource of 10.5 million tonnes at 1.6% copper and 21g/t silver, and drill intercepts including 50 metres at 5.55% copper. Kaoko's presentation put Midas's market capitalisation at approximately A$226 million as at 4 May 2026. That figure is now four months old and Midas has re-rated since. Section 06 has it at roughly A$324 million at 3 September 2026, and it is that later number, not the one in Kaoko's slide, that a reader should hold in mind.
That comparison is useful, and it needs its counterweight. Midas has a JORC Inferred Mineral Resource. Kaoko has visual logging from two holes. One company has established defined tonnes and grade, and the other has established the presence of visible copper minerals. Most exploration companies never close the distance between those two positions.
Framing the upside, with its counterweight
If the assays confirm what the core suggests, and if the mineralisation proves continuous across the 2.2km corridor between Otniel and Donkey Hill, then a company at A$174 million with a defined resource in an underexplored belt during a copper bull market could be worth a multiple of that. Midas is the company's own comparable and it is at roughly A$324 million on a 10.5Mt Inferred Resource. Midas got there with a defined resource rather than with visual logging, and its own price has moved a long way in twelve months, so it is a moving benchmark rather than a fixed one. Two things have to be said in the same breath. Midas got there with a defined resource rather than with visual logging, and its own price has moved a long way in twelve months, so it is a moving benchmark rather than a fixed one.
The counterweight carries equal weight. Most explorers that log visible mineralisation never convert it into a resource, and visual logging often fails to survive the laboratory. The common sequence is that a geologist logs 6% malachite by volume, the assay returns 0.4% copper, and the share price gives back the move within a day. The shareholders who bought at the top of the visual announcement carry that loss. A market capitalisation that can multiply can also halve. The stock closed at A$0.735 on 1 September and at A$2.50 on 3 September, and the placement was priced at A$2.20.
This is a statement about market behaviour and scale. It is explicitly not a valuation, and it is not a reason to act in place of the Samso Call.
Newsflow that will establish value
Assays from DDOT001 and DDOT002. Expected within four to six weeks of 2 September 2026. This is the settling event for the whole workup.
DDOT003, DDOT004 and DDOT005. DDOT003 tests along strike. Until a hole from a second collar hits the same zone, continuity is a hypothesis.
The move to Donkey Hill. Donkey Hill is the company's stated primary target and hosts the 69.6% copper grab sample. It has not been drilled.
Confirmation of EPL 7608 and EPL 7943 renewals. A dated grant, in an announcement.
Karibib geochemistry. A coherent multi-kilometre anomaly would justify the earn-in payments. A weak or incoherent result would raise a fair question about whether they should continue.
A second rig. Named in the placement's use of funds on 7 September, and still described in the same week's presentation as under investigation. When it reaches site, and how many metres it adds, is the thing to watch.
The next capital raise. Done, on 7 September, at A$2.20 for A$20 million. It was priced 12.0% below the last close and 20.2% above the fifteen-day average. At the June quarter's burn the funding question is settled for some years.
8 WHAT WOULD CHANGE OUR MIND
The case getting stronger
Assays confirming meaningful copper grades over the logged intervals would establish a discovery rather than a prospect. What counts as meaningful depends on width and depth, and at 40 metres from surface across tens of metres the bar is lower than it would be at 400 metres. Grades of 1% copper or better over broad intervals from that depth would be a serious result.
A hole from a second collar hitting the same zone would convert continuity from interpretation to observation. Drilling at Donkey Hill, where the highest surface grades were recorded, intersecting something comparable would suggest a district rather than a prospect. Confirmation of the licence renewals would remove the single largest binary risk under the whole company.
One of these tests has already been answered. The capital raise was done on 7 September at A$2.20, a 12.0% discount to the last close and a 20.2% premium to the fifteen-day average, with new and existing long-only global institutions reported on the register. That is a result in the company's favour on funding. The assays are a separate question.
The case getting weaker
An assay result materially below what the visual logging implies is the most common outcome of this sequence. Copper oxide minerals are highly visible in core, so a small volume percentage can look substantial to the eye.
A poor result on true width, where the drilled interval proves to be a shallow angle through a much narrower zone, would shrink the system without changing a single reported number. Failure or delay in the EPL renewals would affect both Chalkos licences at once, and the position remains pending on the public record. Movement on Namibia's draft Minerals Bill toward mandatory local equity would change the value of everything the company holds.
The settling event
The assays from DDOT001 and DDOT002, expected in the four to six weeks from 2 September 2026. Everything in this workup is provisional until they land. The company has said it is expediting them, which is the right call and also means there is no long window in which to make up your mind.
9 MANAGEMENT AND DNA
The board is small, experienced and thinly stretched, which is normal for a company of this size.
Gerard O'Donovan is Managing Director and CEO. His background includes senior roles with Pilbara Minerals and Rio Tinto and an executive directorship at Sun Silver. He holds 3,500,000 shares on the current Market Index register and 1.5 million options, and bought 68,490 shares on-market at 48 cents on 22 May 2026. The prospectus recorded 3,750,000 shares at admission. The two figures do not reconcile and the company is where that is settled. On-market buying by a managing director two weeks after listing is a modest but positive signal.
Mark Thompson is Non-Executive Chair. He founded Talga Group and led it as Managing Director, and previously worked at Western Mining Corporation and Sons of Gwalia. Talga is a genuine credential. It is a company he took from nothing to a listed graphite developer with a European processing strategy, and it demonstrates a willingness to stay with a story for a long time.
Jody Dahrouge is a Non-Executive Director and the technical anchor on the board. He founded Dahrouge Geological Consulting in Canada and specialises in early-stage project generation across base metals, rare earths and uranium. This is the right person to have on the board of a company whose entire proposition is generative exploration.
Brett Tucker is CFO and Company Secretary, a chartered accountant with a background in audit, compliance and IPOs.
In country, Lisias Pius is Country Manager and Dr Ismael Kangueehi is Exploration Lead, holding a PhD in Earth Sciences from Stellenbosch. Both are Namibian. Kaoko has also engaged local Namibian contractors for site works and drilling, awarding the maiden drilling contract to Optimine Exploration and Drilling Namibia. Callum Standing, a co-founder, was appointed Consulting Geologist in August 2026, having previously worked at SQM, Chalice Mining and Liontown Resources.
The DNA read
On appetite the record is good. This company listed on 7 May, mobilised field teams within days, reordered its own drill plan in June on the evidence, awarded a drill contract on 23 July, and had two holes in the ground and reported by 2 September. Four months from listing to first drill results is fast, and it was done with two Namibian projects on two different belts.
On capability the geological bench is genuine, both on the board and in country. The Namibian presence is operational rather than nominal. Community and conservancy engagement has been reported specifically, and at Chalkos, which is inside the Anabeb Conservancy, that carries more weight than it would in Western Australia. The company's own documents differ on the tenure. The prospectus describes the Chalkos licences as being on State land within the conservancy, and the JORC table in the 2 September announcement describes EPL 7943 as communal land.
Two things sit on the other side of the ledger. Directors and management fees are budgeted at A$518,840 a year against a two-year Karibib exploration budget of A$500,000. That ratio is not unusual for a small ASX explorer and it is still worth stating plainly. And there is no long shared track record here. Kaoko is fourteen months old as a corporate entity. The individuals have history. The team, in this configuration, does not.
The board raised A$20 million within a week of the drilling announcement, priced 12.0% below the last close and 20.2% above the fifteen-day average, and put the money against a second rig and an expanded programme. On appetite, and on the ability to raise, that is a good result. It says nothing about what the assays will show.
10 SAMSO CONCLUDING COMMENTS
SAMSO CALL: WATCH & DYOR The settling event we are watching is the assay results from DDOT001 and DDOT002, expected within four to six weeks of 2 September 2026.
I have watched this exact sequence of events play out many times on the ASX. A junior explorer drills its first holes, the geologists see copper in the core, the company writes a careful announcement with cautionary notes in bold on every page, and the market ignores every one of those notes and doubles the stock in a session. Sometimes the assays arrive and confirm it. More often they do not, and the same market that doubled it takes it all back in a morning.
What makes Kaoko worth the attention is not the price move. It is the ground. Two exploration licences covering 39,000 hectares, one of which has never had a single recorded exploration programme run over it, in a belt that is geologically similar to the Central African Copperbelt and that nobody has systematically tested with modern methods. That is a genuinely scarce position in 2026. Most of the world's easy copper ground was picked over decades ago.
The company's own independent geologist is straight about the limits of the analogy.
"Whilst the Kaoko Belt shares similarities with the Central African Copperbelt, it is not an exact analogue." "The Kaoko Belt is Neoproterozoic in age and may suggest a different style of mineralisation which will be expanded on with further exploration and understanding." Kaoko Metals Prospectus, 23 February 2026, Section 4.5, summarising the Independent Technical Assessment Report |
The Zambian and Congolese systems are copper-cobalt and the Kaoko Belt is copper-silver. Most economic sediment-hosted copper occurs in basins older or younger than this one. Those caveats sit in the prospectus in the geologist's own words, and I would rather see them there than not.
Sixty metres of visible copper from 36 metres down, on the first attempt, on ground nobody has drilled before, is a real result. It is also still only a photograph. The distance between what the eye sees and what the laboratory measures is where this investment sits at the moment, and that distance closes within weeks.
The A$20 million raise answers a question that hangs over every explorer at this stage, which is whether the company can fund the work in front of it. Kaoko now has over A$24 million of cash, so it can. It will need a great deal more drilling to prove this up, and drilling is expensive. Two holes and a set of visual logs are the beginning of the work rather than the end of it. The raise lets the company keep a rig turning and keep the newsflow going while it finds out what it has. It also means the next raise is not priced off whatever the assays say.
WA1 Resources is the comparison I keep coming back to. WA1 drilled its first programme in the West Arunta in Western Australia in November 2022 and made the Luni discovery, which the company describes as the most significant niobium discovery in more than seventy years.
Kaoko could turn out to be a similar situation, a fresh discovery on ground nobody has tested that develops into a Tier 1 deposit. Tier 1 is industry shorthand for a deposit big enough, rich enough and long enough lived that the major mining companies want to own it. I do not know whether that is what this is, and neither does anyone else at this point.
The part worth taking from the comparison is how long the road is even when it works. WA1 made its discovery in November 2022 and published its Mineral Resource in May 2026, and the pre-feasibility study is still not finished. That is three and a half years of drilling after the discovery hole. Kaoko is at the beginning of that road and the assays are the first step along it. Source. WA1 Resources project page, Luni Mineral Resource of 220 million tonnes at 1.0% Nb2O5 dated 13 May 2026, and the company's own account of the discovery.
So the call is WATCH & DYOR, and I want to be specific about what the DYOR means here, because it is not a hedge. It means do the work now, in the next four weeks, while the assays are still in the laboratory. Read the 2 September announcement in full, including Appendix A and the JORC table. Understand that the visual estimates are volume percentages and not grades. Look at the escrow schedule and know when the 11.57 million shares come free. Ask the company about the licence renewals and about the vesting conditions on the 5.55 million performance rights. Decide, in advance, what assay result would make you a buyer and what result would make you walk away. Then wait for the number.
What I would not do is decide anything about this company on the basis of a core photograph and a 151% day. That is not because the photograph is misleading. It is not, and I think the geology behind it is interesting. It is because the price already assumes an answer to a question that has not been asked yet.
So the question worth sitting with is this. Are you willing to pay today's price for an answer that has not arrived yet?
