Critical Resources Limited (ASX: CRR) continues to position its Mavis Lake Lithium Project in northwestern Ontario as one of the more advanced hard-rock lithium assets in the region (Figure 1). The Company has expanded its landholding by 25% to more than 400 km², strengthened its geological footprint, and advanced exploration to position the Project as a future supplier to the North American battery supply chain.

IRIS Metals Limited (ASX: IR1) has secured an exclusive right to farm-in to the Finley Basin Tungsten Project, located in Granite County, Montana, USA, through a binding Heads of Agreement with Finley Mining Inc and its shareholders. The transaction provides IRIS with entry into a historically high-grade tungsten system within a mining-friendly U.S. jurisdiction, aligning with its broader critical minerals strategy and U.S.-focused asset base.

Cyclone Metals is advancing early-stage gold exploration within structurally prospective ground in Central Otago. The Company holds a 100% interest in both the Waikerikeri and Drybread permits, which lie proximal to established gold systems, including Santana Minerals’ Rise & Shine project and OceanaGold’s Macraes Flat operation. These projects are positioned along major regional structures, notably the Dunstan Range Fault, a recognised control on gold mineralisation in the r

Exploration activity across the Gawler Craton is accelerating, driven by a convergence of high-grade gold discovery and aggressive drill programs now underway. Marmota Limited’s (ASX: MEU) maiden drilling at the Greenewood gold discovery (Figure 1) has delivered some of the most spectacular near-surface gold results recorded in the region since the Challenger Mine’s breakthrough in 1995, defining almost one kilometre of continuous mineralisation.

Astral Resources NL (ASX: AAR) has taken a major step toward bringing the Mandilla Gold Project into production with a heavily oversubscribed A$65 million placement. The funding provides a meaningful runway for completing the Mandilla Definitive Feasibility Study (DFS), progressing early-works, and continuing exploration. All projects sit immediately south of Kalgoorlie — one of Australia’s most productive gold jurisdictions.

Lion Rock Minerals Ltd (ASX: LRM) has reported further high-grade rutile and heavy mineral (HM) results from its Minta Rutile and Monazite Project, located in central Cameroon (Figure 1). The latest drilling confirms the scale, grade, and consistency of residual and alluvial rutile mineralisation across a vast exploration footprint, while reinforcing strategic alignment with global mineral sands producer Tronox Holdings plc.

E79 Gold Mines Limited (ASX: E79) has moved decisively to secure full control of the Cue Gold Project in Western Australia's Murchison region. The Project sits within the historic Day Dawn Goldfield, immediately south of the renowned Great Fingall Mine, an area long recognised for its high-grade quartz-reef–hosted gold systems. The Company has now exercised its Option Agreement to acquire six tenements, opening the door for immediate, project-wide exploration.

Heavy Rare Earths Limited (ASX: HRE) has reported encouraging reconnaissance rock chip sampling results from its Radium Hill Project in South Australia’s Curnamona Province (Figure). The work has outlined an extensive, 8 km-long structural corridor associated with the historic Radium Hill uranium mine, highlighting significant enrichment in scandium, yttrium, rare earth elements (REEs), uranium, and vanadium.

The discussion focused on tungsten, antimony, and gold, but more importantly, on mineral systems thinking—how deposits form, why certain geological settings matter, and why Pioneer’s ground selection in Idaho, USA, was anything but random. As someone who has followed tungsten closely, this was a conversation that went well beyond commodity hype and into the fundamentals of discovery.

Sun Silver Limited (ASX: SS1) has delivered yet another step-change in the scale of its cornerstone Maverick Springs Silver–Gold Project, located in northeast Nevada, approximately 85km from Elko and proximal to the world-renowned Carlin Trend. The latest Mineral Resource upgrade increases the total Inferred Mineral Resource to 539Moz silver equivalent (AgEq) at 71 g/t AgEq, representing an additional 59Moz AgEq uplift from the 2025 exploration and re-assay program.

OD6 Metals Ltd (ASX: OD6) has commenced a Downhole Electromagnetic (DHEM) survey at the Gulf Creek Copper Project, located near Barraba in northern New South Wales (Figure 1). The program marks a significant technical step forward in assessing the project’s volcanogenic massive sulphide (VMS) copper potential, following the completion of four diamond drill holes and earlier reverse-circulation (RC) drilling completed in 2025.

Rumble Resources Limited (ASX: RTR) continues to advance the Western Queen Gold Project, located approximately 90 km northwest of Mt Magnet in Western Australia. The Company has released a Scoping Study for the Western Queen South deposit, outlining a technically simple, low-capital underground development that sits adjacent to multiple toll-treatment options within a 200 km radius. The Project is supported by a strong historical production record.

Pioneer Minerals Ltd (ASX: PMM) (formerly Pioneer Lithium Ltd) is advancing its North Pine Project in Idaho, USA, a region renowned for its Tier-1 critical minerals endowment (Figure 1). The latest field program has delivered multiple high-grade tungsten and gold results from the Springfield Prospect, alongside the identification of a new polymetallic precious-metal system at Silver Cliffs. These results materially expand the exploration proposition across the broader North P

Critical Resources Limited (ASX: CRR) has completed the acquisition of the Cap Burn Gold Project in the Otago region of New Zealand’s South Island (Figure 1), securing Ministerial approval for the transfer of exploration permit EP60300. The Company has also finalised the transfer of the land access agreement with the local landowner, clearing the way for an inaugural drilling program to commence in the coming weeks.

Heavy Rare Earths Limited (ASX: HRE) has released new findings that reshape the potential of its Prospect Hill Project in the northern Flinders Ranges of South Australia. What was once viewed primarily as a tin-focused system is now revealing a strong polymetallic signature, supported by historic drilling that confirms significant silver, copper, lead, and zinc mineralisation alongside high-grade tin.
