Announcement
Lion Rock Minerals Limited (ASX: LRM) has secured a strategic placement and technical partnership with Tronox Holdings plc (NYSE: TROX)—one of the world’s largest vertically-integrated titanium dioxide and zircon producers. This is not just funding; it’s an alignment with an operator that mines, upgrades, and markets titanium feedstocks (including rutile) and rare earth-bearing monazite at an industrial scale. The move signals an intention to fast-track drilling, resource definition, and metallurgy at Minta (Cameroon), with in-country lab capability also on the agenda.

Lion Rock Chief Executive Officer, Casper Adson, commented:
“We are delighted to welcome Tronox as a strategic investor and development partner in the Minta Monazite and Rutile Project. Tronox’s senior leadership team has visited site, met with key government stakeholders and completed initial due diligence before committing to this investment.
“Their participation provides both capability and immediate cash - creating a foundation for collaboration in rare earth and titanium feedstock development, processing and market access. This partnership aligns LRM’s high-quality resource base with Tronox’s established technical and operational expertise, including its strategic consideration in the downstream rare earth value chain.
“With Tronox’s support, Lion Rock is positioned to accelerate the development of one of the most significant undeveloped monazite and rutile projects globally, delivering value for shareholders and contributing to secure, sustainable supply chains of critical minerals.”
Tronox Chief Executive Officer, John Romano, commented:
“The Lion Rock Project represents an opportunity for Tronox to advance its critical mineral strategy in rare earths and high-grade rutile. Our investment in Lion Rock reflects the exciting opportunity we see in the project’s potential to create meaningful value. We look forward to working with the Lion Rock team to assist with their development of this important resource as we continue to expand our presence in the rare-earths value chain.”
Highlights - A New Narrative - Rutile and Monazite
A$8.6m placement for ~5%: Tronox to invest A$8.6m via placement at A$0.056 per share (153,195,857 new shares); settlement expected 15 Oct 2025.
Strategic partner with operating depth: Tronox brings mine-to-pigment know-how across titanium feedstocks (rutile) and monazite (rare earths), plus downstream processing expertise and market access.
Use of proceeds—rapid technical work: Funds to accelerate drilling, resource definition, metallurgical testwork/flowsheet validation (monazite & rutile), product qualification, and to establish in-country analytical capacity in Cameroon.
On-ground validation: Tronox senior leadership visited site in Cameroon and met key stakeholders before committing.
Right to maintain: LRM will seek an ASX waiver to allow Tronox to maintain its holding in future raises (while ≥2.5%).
What this partnership actually means
This is a potential marriage of funding and an off-taker. Is it a rutile and monazite menu ? . For Minta project, it will mean a faster conversion of geological potential into metallurgical reality and, critically, product qualification—a key de-risking step for both rutile and monazite-derived rare earth streams. For Tronox, it’s a foothold in high-grade rutile and an expansion vector in the rare earth value chain.
Transaction details at a glance
Placement: 153,195,857 fully paid ordinary shares @ A$0.056; issued under LR 7.1; Tronox ~5% on completion.
Timing: Settlement expected 15 Oct 2025.
Commercial & Technical Services Agreement: Tronox to provide services to support development.
Proceeds: Drilling, resource definition, metallurgy, flowsheet validation (rutile & monazite), product qualification, in-country lab, working capital.
Who is Tronox (and why that matters)
Tronox is a global TiO₂ and zircon heavyweight with ~6,500 employees across six continents, operating mines in South Africa and Australia, plus eight pigment plants worldwide. The business integrates mining, upgrading (high-grade feedstocks), chlorination, separation, and downstream products—including monazite handling—and is actively expanding in rare earths. That operating breadth and process IP are directly relevant to Minta’s rutile and monazite flowsheets.
Project snapshot — Minta (Cameroon)
Tenure: 18 granted exploration permits + 3 under application across ~8,800 km² in a rutile-bearing province of central Cameroon.
Commodity mix: Rutile (fine + large angular nuggets), monazite, zircon; alluvial & residual styles with little to no overburden in places.
Why it’s interesting: The presence of large, angular rutile nuggets across broad areas suggests an additional rutile source that may materially lift total Valuable Heavy Mineral (VHM) grade in target horizons.
Other occurrences: Zones of very high-grade zircon at Minta Est; plus alluvial and hard-rock gold in the NE, coincident with a geophysical anomaly linked to granitic intrusions.

What to watch next
Drilling cadence & scope: Whether LRM broadens drill coverage to convert areas with rutile nuggets and fine rutile into reportable resources.
Metallurgy & flowsheet: Bench/variability testwork across rutile and monazite domains; clarity on recoveries, impurities, and product specs.
Product qualification: Progress on bulk samples and off-take-style qualification pathways, especially for chlorination-grade rutile and monazite-derived REE feed.
In-country lab: Build-out and commissioning milestones for Cameroon-based analytical capacity (turnaround times and QA/QC).
ASX waiver outcome: Confirmation of Tronox’s right to maintain ownership in future raisings (≥2.5% condition).
Samso Concluding Comments
Tronox stepping onto the register is an operator's vote of confidence that narrows the gap between intriguing geology and saleable product. Tronox is also indicating that the monazite is not a by-product. Is this a change in the focus of the narrative? Is this now a monazite narrative with some good ruitle numbers? Well, I think with the Rare Earth momentum starting to come back, in my opinion, this is what I am reading.
This is not a negative change in direction; I think this is merely a shift in labeling. The value creation from both products is what shareholders should be focusing on. The confidence in Tronox becoming a shareholder of their potential feed source is a very good part of the Lion Rock journey.
For Minta, the hurdle to create the value proposition is now tied to how quickly Lion Rock can convert surface evidence (rutile nuggets, fine-grained rutile, monazite) into defined resources and a defensible flowsheet. Product qualification will be the market’s litmus test.
There is never a better period of the Lion Rock pathway where execution now matters more than narrative. Investors will want drilling results, mineral assemblages (only because that is what the investor's understanding is seeking), and some form of read on the future potential recoveries/impurities, and clear pathways on timing for the news. If the in-country lab comes online and shortens turnaround times, this will help in answering the previous questions, and that should be the management focus for this period.

Don't forget that the usual risks still apply for any form of investing thoughts into Lion Rock. The Tronox partnership is a very good sign and this may lead to pressure to chase, but I caution this thinking. The recent share price devaluation (Figure 3) since this ASX release is worrying for the less informed retail space.
As always, DYOR and keep an eye on the news coming out.
