Orion Glencore copper-zinc deal backs South Africa’s Prieska revival

Orion Glencore

The Orion Glencore copper-zinc deal will inject up to $250mn into South Africa’s Prieska mine redevelopment. Orion Minerals signed a non-binding term sheet with Glencore covering staged financing and long-term concentrate offtake, making the Orion Glencore copper-zinc deal a cornerstone funding package for the project. As a result, the Orion Glencore copper-zinc deal positions Prieska as a significant future supplier of copper and zinc for the energy transition.

Orion Glencore copper-zinc deal structures phased financing for Uppers and Deeps

The agreement splits funding between Prieska’s near-surface “Uppers” orebody and the deeper “Deeps” deposit. Orion expects $40mn to flow first into the Uppers to fast-track initial mine development and near-term output. Meanwhile, a second tranche of $160mn–210mn will fund full build-out of the Deeps, subject to due diligence and final documentation.

Glencore also offers an early drawdown facility of up to $50mn for Deeps pre-works. This structure allows Orion to de-risk critical engineering and infrastructure before committing to the full capital envelope. Therefore, the Orion Glencore copper-zinc deal blends development capital with commercial offtake in a way that lowers financing risk.

Under the term sheet, Glencore will take 100pc of bulk concentrates from the Uppers for five years. It will also off-take 100pc of copper and zinc concentrates from the Deeps for 10 years. Orion retains flexibility on delivery points and advance sales, giving it room to optimise logistics and pricing across global markets. First production is targeted for late 2026.

Prieska and Okiep strengthen South Africa’s energy transition metals pipeline

Prieska carries a sizeable resource base to underpin the Orion Glencore copper-zinc deal. The project hosts 31mn t grading 1.2pc copper and 3.6pc zinc. A definitive feasibility study released in March outlined a two-phase development plan. It targets a combined 13.2-year mine life with steady-state output of 30,000 t/yr copper and 65,000 t/yr zinc.

These volumes are material in the context of tightening global copper and zinc supply. Copper is central to electrification, grid build-out and EV infrastructure. Zinc remains key for galvanised steel and infrastructure corrosion protection. Therefore, Prieska aligns directly with energy transition metal demand.

At the same time, Orion continues to advance its Okiep copper project in the same region. Together, Prieska and Okiep could re-establish the Northern Cape as a meaningful copper district. The Orion Glencore copper-zinc deal sends a positive signal for South African base metals investment, even as regulatory and power challenges persist.

The Metalnomist Commentary

Glencore’s willingness to provide both capital and long-dated offtake confirms Prieska’s strategic appeal in a tightening copper-zinc market. For Orion, the deal reduces financing uncertainty and validates its district-scale ambitions in the Northern Cape. Market participants should now watch execution discipline, permitting progress and how quickly Prieska can move from term sheet to binding financing and construction.

Thunderbird zircon mine financial support boosts liquidity as zircon demand weakens

Thunderbird, Zr Mine

Thunderbird zircon mine financial support is flowing as mineral sands markets stay soft. Sheffield Resources and Yansteel will inject A$6.5mn into their Kimberley Mineral Sands joint venture to fund working capital at the Thunderbird mine. Meanwhile, the venture faces near-term loan repayments due by 31 December to Northern Australia Infrastructure Facility (NAIF) and global creditor Orion Resource Partners.

Debt pressure drives talks on deferrals and restructuring

Debt maturity pressure is driving the Thunderbird zircon mine financial support package. The venture is discussing payment deferrals or credit restructures with its lenders. However, the partners cannot guarantee a successful outcome. Sheffield Resources also has not committed further working capital beyond this injection.

The funding stack remains large relative to current market conditions. NAIF provided an A$160mn facility and Orion Resource Partners provided a $110mn facility in 2022. Therefore, lenders hold strong security through asset backing and owner guarantees. The Orion package also includes a 1.6% royalty tied to sales volumes.

Output ramp plans clash with weak zircon pricing signals

Operational momentum continues at the Thunderbird site despite softer demand. Kimberley Mineral Sands mined 10.4mn tonnes of ore and produced 740,666 tonnes of heavy mineral concentrate in the July 2024 to June 2025 period. Meanwhile, the project aims to ramp to 220,000–240,000 t/yr of zircon concentrate and 900,000–950,000 t/yr of ilmenite concentrate by July-September 2027.

Commercial support is also tightening around inventory risk. Yansteel agreed to buy all unsold zircon concentrate at a fixed price, which stabilizes cash flow. It also holds a 100% ilmenite offtake agreement, which secures a key revenue stream. However, broader signals still point to a zircon downturn. Large producers across the United States, Australia, and South Africa reportedly cut export prices to China in late October.

Competitive stress is spreading to peers as well. Iluka Resources will pause its Cataby mine operation for one year from 1 December. Therefore, the market is signaling a deliberate supply response to protect margins.

The Metalnomist Commentary

This funding round highlights how quickly zircon price weakness turns into balance-sheet risk. Meanwhile, fixed-price offtake can protect cash flow but can also cap upside. Producers that align debt terms with demand cycles will control the next expansion wave.

US UAE Critical Minerals Fund Targets Near-Term Supply Security

Orion Resource Partners

The US UAE critical minerals fund aims to rapidly strengthen non-Chinese supply chains for strategic metals and minerals. The new vehicle, led by the US International Development Finance Corporation (DFC), Orion Resource Partners and UAE sovereign fund ADQ, starts with $1.8bn in commitments and targets $5bn over time. As a result, the US UAE critical minerals fund immediately positions itself as one of the largest dedicated pools of capital in this space.

US UAE critical minerals fund focuses on producing and near-producing assets

The US UAE critical minerals fund will prioritise existing or near-term producing assets rather than early-stage exploration. This approach reflects government urgency to secure physical flows of rare earths, battery metals and other strategic materials within this decade. Therefore, capital will likely concentrate on brownfield expansions, processing plants and last-mile infrastructure instead of high-risk greenfield drilling campaigns.

Public-private partnerships in critical minerals are becoming a defining feature of the energy transition. Earlier this week, Appian Capital Advisory and the International Finance Corporation launched a $1bn fund for similar purposes. Meanwhile, the US government has repeatedly partnered with private investors as it tries to dilute dependence on Chinese refining and processing capacity.

US security strategy extends from stockpiles to allied supply chains

The new US UAE critical minerals fund complements a broader US security toolkit that includes stockpiles and equity stakes. The US Defense Logistics Agency has been issuing requests for proposals to expand domestic critical mineral inventories beyond current annual production and imports. In parallel, the Pentagon acquired a 15pc stake in MP Materials, the only integrated US rare earths producer, backed by an offtake agreement with a price floor for NdPr products.

However, Washington is also exporting this strategy through alliances. The recent US–Australia agreement will channel at least $1bn from each government into priority critical minerals projects in both countries over the next six months. By aligning funds such as the US UAE critical minerals fund with bilateral deals, the US is stitching together a network of “friendly” mines, refineries and separation plants across multiple jurisdictions.

Over time, these overlapping initiatives could create alternative pricing references and more transparent offtake structures. As a result, investors may gain better visibility on project cash flows in a market still dominated by opaque Chinese contract terms and discretionary export policies.

The Metalnomist Commentary

The US UAE critical minerals fund underscores how geopolitics is now hard-wired into capital allocation for mining and processing. If the consortium executes quickly on producing and near-producing projects, it could materially accelerate non-Chinese supply in rare earths and other key minerals. The real test will be whether these funds can overcome permitting delays, community concerns and price volatility that have historically slowed critical minerals development.

Australia’s Thunderbird zircon mine financial support targets debt deadlines amid weak demand

Thunderbird Zr mine

Australia’s Thunderbird zircon mine financial support is arriving to protect working capital and debt compliance. Sheffield Resources and Yansteel will invest A$6.5 million into their Kimberley Mineral Sands venture. The funding supports operations at the Thunderbird mine as zircon demand weakens. Therefore, Australia’s Thunderbird zircon mine financial support is tightly linked to lender obligations.

The venture must make repayments by 31 December to two lenders. The lenders include Northern Australia Infrastructure Facility and creditor Orion Resource Partners. Meanwhile, the partners are negotiating deferrals or credit restructures. However, the company says success is not guaranteed.

Loan packages and royalties raise pressure as zircon demand softens

The venture secured major loan facilities in 2022. NAIF opened an A$160 million facility, while Orion opened a $110 million facility. Both loans are secured against Thunderbird assets and guaranteed by the owners. As a result, any covenant stress can spill back to shareholders.

Orion’s financing includes a 1.6% royalty on sales tied to up to 8.2 million tonnes per year of ore. Meanwhile, revenue pressure rises when zircon prices weaken. Therefore, Australia’s Thunderbird zircon mine financial support aims to keep liquidity stable through a demand slump.

Ramp plans remain, but the market is forcing price and output discipline

Thunderbird’s operating metrics show scale and ramp ambition. KMS mined 10.4 million tonnes of ore and produced 740,666 tonnes of heavy mineral concentrate in FY2024–FY2025. The venture began processing in late 2023 and shipped first zircon in January 2024. It plans to ramp to 220,000–240,000 tonnes per year of zircon concentrate and 900,000–950,000 tonnes per year of ilmenite concentrate by July–September 2027.

Yansteel is also tightening offtake support for the project. It agreed to buy all unsold zircon concentrate at a fixed price. It also holds a 100% ilmenite concentrate offtake agreement. As a result, commercial backing offsets some spot market weakness.

Zircon producers are cutting export prices to China because demand is soft. Meanwhile, Iluka Resources will pause its Cataby mine for one year from 1 December. Iluka’s zircon concentrate sales fell 45% year on year in July–September. Therefore, the downturn is regional and structural, not project-specific.

The Metalnomist Commentary

Mineral sands projects can ramp volumes, but they cannot ramp demand. Meanwhile, debt timing forces hard choices when zircon prices fall. Therefore, Thunderbird’s next milestone is financial flexibility, not nameplate capacity.

Vale Base Metals Deal Creates New Path for Thompson Mine Complex

Vale Base Metals

Vale Base Metals will enter a new consortium deal that could reshape the future of the Thompson Mine Complex in Manitoba. The planned transaction gives the Canadian nickel asset fresh capital, new partners, and a clearer role in North America’s critical minerals supply chains.

The consortium will include Exiro Minerals, Orion Resource Partners, Canada Growth Fund, and Vale Base Metals. Together, the partners plan to invest up to $200mn in the Thompson Mine Complex through a new company called Exiro Nickel. The structure gives the three partners an 81.1pc controlling stake, while Vale Base Metals retains an 18.9pc minority position.

Vale Base Metals will also sign an offtake agreement for nickel concentrate produced at the Thompson mill. This is strategically important because it allows the company to maintain exposure to nickel units while reducing direct ownership of the Manitoba operations. The transaction is expected to close by the end of 2026, subject to regulatory and government approvals.

Thompson Nickel Belt Gains Long-Term Investment Platform

The Thompson Mine Complex remains a significant nickel asset because it includes two underground mines, a mill, and exploration ground across the 135km-long Thompson Nickel Belt. The asset produced 12,000t of finished nickel in 2025, up 21.2pc from 9,900t in 2024.

The deal creates a new Canadian nickel producer focused on extending the value of the Thompson Nickel Belt. Exiro Nickel’s role will be to steward the asset as a long-life platform, while Vale Base Metals continues day-to-day operations until the transaction is completed.

This structure reflects a wider trend in mining portfolio management. Large diversified producers are increasingly reviewing mature or non-core assets, while specialist investors and government-backed funds are stepping in where critical minerals policy supports long-term development. For Thompson, the result could be a more focused ownership model and stronger investment case.

Nickel Supply Security Supports Canada’s Critical Minerals Strategy

The transaction strengthens Canada’s position in critical minerals supply chains tied to batteries, clean energy technologies, manufacturing, and industrial resilience. Nickel remains essential for stainless steel and selected battery chemistries, making stable North American supply strategically valuable.

Canada Growth Fund’s participation is especially notable because it links the project to broader national industrial policy. Government and provincial support suggests that Thompson is not being viewed only as a mine-level investment. It is also being treated as part of Canada’s long-term critical minerals infrastructure.

Vale Base Metals will remain connected to the asset through its minority stake and concentrate offtake agreement. That gives the company continued access to production while allowing new partners to fund the next phase of the Manitoba platform. For buyers, the arrangement could support more reliable nickel supply from a stable jurisdiction.

The Metalnomist Commentary

The Vale Base Metals transaction shows how critical minerals policy is changing asset ownership. Mature nickel operations can gain new strategic value when capital, government support, and offtake structures align around supply security.

Lithium Americas to Start Thacker Pass Build in May 2025

Lithium Americas to Start Thacker

Lithium Americas confirms Thacker Pass construction start in May, targeting production by late 2027 to boost U.S. lithium supply.

Thacker Pass Lithium Project Set for Major Construction Phase

Lithium Americas (LAC) will begin major construction at its Thacker Pass project in Nevada starting May 2025. The company aims to reach initial production by late 2027, reinforcing its role in North America's lithium supply chain. Engineering progress has already reached 55% and is expected to exceed 90% design completion by year-end.

LAC’s CEO Jonathan Evans emphasized the readiness to move forward after securing funding and partnerships. “Once we declare final investment decision, our team will focus on execution,” Evans said. This milestone follows the finalization of a $2.26 billion Department of Energy (DOE) loan in October 2024.

Funding and Strategy Behind the U.S. Lithium Push

In March 2025, LAC received a $250 million investment from Orion Resource Partners to support Phase 1 development. The DOE loan—secured under the Advanced Technology Vehicles Manufacturing Loan Program—will help build processing infrastructure. Meanwhile, LAC reported a $42.6 million net loss in 2024, up from $5.1 million in 2023, mainly from DOE and GM deal costs.

The Thacker Pass project is one of the most advanced lithium developments in the United States. Its strategic importance has grown amid increasing global demand for EV battery-grade lithium. The project also marks a significant step toward U.S. efforts to reduce reliance on imported lithium, especially from China.

The Metalnomist Commentary

Thacker Pass isn't just a mining project—it’s a cornerstone of U.S. energy security policy. As governments and automakers race toward EV adoption, domestic lithium supply is becoming as critical as oil once was. The Metalnomist will be watching closely as Lithium Americas enters this pivotal execution phase.

Tharisa underground chrome and PGM project extends Bushveld mine life

Tharisa

Tharisa underground chrome and PGM project plans mark a major shift in its South African operations. The Tharisa underground chrome and PGM project will replace the existing open pit mine as it depletes, securing long-term output from the Bushveld complex. This strategic move aims to stabilise chrome and PGM supply while leveraging stronger platinum prices and future demand growth.

Long-life strategy for Bushveld chrome and PGM supply

Tharisa will invest $547mn over the next decade to develop the underground complexes, Apollo and Orion. These underground units will enter first production in 2031, as the open pit approaches depletion. The Tharisa underground chrome and PGM project is designed to match and then exceed the current 5.6mn t/yr ore mining capacity.

As a result, Tharisa expects to maintain existing chrome and PGM concentrate output levels and create room for expansion. The underground expansion will extend the life of the overall operation by more than 50 years. This life extension is critical for downstream smelters, refiners and automotive PGM users planning long-term contracts.

Recent production trends highlight why the transition matters. PGM output fell by 6.5pc year on year in April–June, with chrome concentrate down by 3.9pc. However, quarter-on-quarter volumes recovered, with PGMs up 6.2pc and chrome concentrate up 3.9pc from January–March. The Tharisa underground chrome and PGM project therefore seeks to smooth volatility and anchor a more predictable supply profile.

Platinum price strength supports underground investment case

Platinum prices have recently surged to their highest level in 11 years. Benchmark assessments put platinum around $1,592/troy oz, with palladium at $1,285/troy oz. This price environment strengthens the economic rationale for deep, capital-intensive underground development.

Therefore, the Tharisa underground chrome and PGM project benefits from supportive revenue expectations, even as near-term production dips. Underground operations typically deliver higher resource recovery and better grade control than mature open pits. Over time, this can offset higher operating and capital costs.

Meanwhile, chrome concentrate remains a key revenue pillar for Tharisa, tied to stainless steel and alloy demand. The combined chrome and PGM basket from the Tharisa underground chrome and PGM project will help diversify risk across stainless, auto catalyst and emerging hydrogen-related applications. For global buyers, this project adds another long-dated node of supply in a market wary of concentration risk.

The Metalnomist Commentary

Tharisa’s move underground signals confidence in long-run PGM and chrome fundamentals despite short-term market noise. For downstream users, the key questions will be project execution, cost control and how this new supply interacts with other Bushveld and global expansions. If delivered on schedule, the project should reinforce South Africa’s role at the core of the PGM and chrome value chain well into the second half of this century.
