The Quad partner nations — United States, Japan, Australia and India — unveiled plans to invest $20 billion to further support the buildout of a reliable critical minerals supply chain in an effort to counter China's dominance, with the framework setting out coordinated investment to accelerate the development of a secure supply chain of minerals powering advanced technology, defense systems, batteries and AI.
The partners intend to mobilize up to $20 billion in government and private sector support through new and existing efforts to strengthen critical minerals supply chains, including in mining, processing, and recycling.
The announcement, made Tuesday during the Quad Foreign Ministers' Meeting in New Delhi, marks one of the most significant geopolitical moves in the mining sector this year as Western allies seek to reduce dependence on Chinese processing capacity.
Quad Partners: $20 Billion Critical Minerals Initiative
The Quad partners intend to mobilize $20 billion in government and private-sector funding of the entire critical minerals supply chain, which includes mining, processing and recycling, according to the US Department of State.
The framework sets out key areas for cooperation among the Quad partners on critical minerals supply chains, with partners intending to identify projects with a Quad nexus, such as those located in Quad partner countries, operated by companies headquartered in Quad partner countries, or supplying Quad markets.
The initiative aims to diversify markets and reduce reliance on China, which processes 90 per cent of global rare earths.
The initiative aims to secure reliable and diversified supply chains for minerals considered essential for advanced technologies, clean energy systems, semiconductor manufacturing, electric vehicles, defence production, and industrial resilience, with the Quad partners intending to mobilize up to $20 billion in combined government and private sector investments to support mining, processing, refining, and recycling of critical minerals across the Indo-Pacific region.
The timing is critical. According to market data, the Lithium ETF (LIT) traded at $87.48, up 2.3% on Wednesday, while the Copper Miners ETF (COPX) gained 2.0% to $87.81, suggesting investors are pricing in stronger demand for battery metals amid supply chain restructuring.
Cameco: Uranium Production Resumes After Flood Disruption
Cameco halted production at Key Lake on May 10 and reduced activity at McArthur River after flood waters partially collapsed the Smoothstone River bridge, a critical transport link used to move materials between the operations.
The company said the disruption has not altered its production plans for the McArthur River/Key Lake operation, while the Cigar Lake mine continued operating normally throughout the incident, and Cameco maintained its 2026 consolidated production outlook of 19.5 million to 21.5 million lb.
Disruptions at McArthur River — one of the world's largest uranium mines and a major contributor to global supply — could further tighten an already undersupplied uranium market and support spot uranium prices, according to BMO analyst Alexander Pearce.
The Uranium ETF (URA) traded at $50.83, up 1.3% according to market data, reflecting continued strength in the nuclear fuel sector despite the temporary logistics challenges.
Cameco reported that the McArthur River mine and Key Lake mill in northern Saskatchewan have resumed full production after a temporary disruption caused by flooding-related transportation issues, with the company's 2026 production plan for this operation unchanged.
Sulphuric Acid Crunch: Battery Metals Costs Surge
Conflict in the Middle East and the closure of the Strait of Hormuz have sent sulphuric acid prices soaring, sharply increasing production costs for lithium, nickel and other critical minerals essential to the energy transition, with Benchmark Mineral Intelligence reporting sulphur prices have climbed more than 50% since the start of the war in Iran, while sulphuric acid prices have more than doubled in some regions.
At least half of global seaborne sulphur trade passes through the Strait of Hormuz, and more than half of global lithium, cobalt, rare earth and purified phosphoric acid production expected in 2026 is exposed to sulphur and sulphuric acid disruptions, according to Benchmark.
Spot acid prices in Indonesia and Chile have climbed above $380 and $440 per tonne respectively as converters scramble for alternative supplies, while battery-grade lithium carbonate prices in China have already risen about 65% this year in US dollar terms.
Sulphur now represents 42% of HPAL nickel costs, up from 26% before the conflict, with Indonesia, the world's largest nickel producer, sourcing 76% of its sulphur imports from the Middle East last year.
The supply squeeze highlights how geopolitical tensions are increasingly disrupting energy transition supply chains, with countries possessing domestic sulphur production capacity likely to gain competitive advantages.
Minera Alamos: Copperstone Gold Mine Gets Green Light
Minera Alamos Inc. announced the results of a pre-feasibility study on its 100%-owned, past-producing Copperstone project located in La Paz County, Arizona, USA.
According to the company's press release, the board of directors has approved fast-track construction following the positive PFS results.
The PFS shows increased Measured & Indicated Resources to 4,054 kt grading 4.83 grams per tonne gold and containing 630 koz gold, representing a 110% increase in contained gold ounces compared to the previous mineral resource estimate, with maiden Proven & Probable Reserves of 1,934 kt grading 4.87 g/t and containing 303 koz gold.
Copperstone is a previously mined property with active mining and environmental permits.
The Project has a NPV-to-capex ratio of 6.4x using base case gold price of $3,500/oz, and NPV-to-capex ratio of 9.2x using spot gold price of $4,500/oz, with the initial capex of $58 M to be comfortably financed by the Company's existing cash balance (Q1 2026, $46 M), excess capacity under the recently closed $75 M revolving credit facility, and ongoing cash flow from the Pan mine in Nevada.
Gold traded at $4,446 per ounce on Wednesday, down 1.6% according to market data, but still well above the project's base case assumptions.
New South Wales: $497M Copi Critical Minerals Project Approved
Australia's New South Wales state has approved RZ Resources' A$693 million ($497 million) Copi mineral sands mine project, which is expected to produce up to 400,000 tonnes of critical mineral ore a year for 18 years, with the approval clearing a pathway to first production in early 2029.
Located 75 km northwest of Wentworth in far southwestern NSW, the mine will produce titanium minerals including rutile, leucoxene and ilmenite, premium zircon, and rare earth elements including monazite and xenotime.
RZ Resources said it has received investment and support for the project from Japan's JX Advanced Metals and Marubeni, with the project's strategic importance formally recognized and receiving support from the US, Japanese, Indian and Australian governments.
The project is expected to create up to 480 direct jobs during construction, transitioning to a 240-strong operational workforce.
The approval comes as Australia strengthens its position in critical minerals supply chains aligned with Quad partners, with the project expected to help secure materials for electric vehicles, wind turbines, defense systems, and telecommunications equipment.
Defense Metals: Hanwha Rare Earth Supply MOU
Defense Metals Corp. announced that it has entered into a non-binding memorandum of understanding with Hanwha Ocean Co. Ltd and its affiliate Hanwha Corporation, signed on May 25, 2026, to explore a strategic collaboration involving the future supply of rare earth elements and potential investment opportunities.
Under the terms of the MOU, the parties intend to evaluate the framework for a potential long-term offtake agreement pursuant to which Defense Metals could supply certain rare earth materials produced from the Company's Wicheeda Project to support Hanwha and its affiliate's manufacturing and supply chain requirements, with the parties also exploring the possibility of a strategic investment by Hanwha or any of its affiliates in Defense Metals.
The agreement comes as Hanwha competes for Canada's multibillion‑dollar submarine program and follows other Canadian partnerships, including MOUs with the Automotive Parts Manufacturers' Association and Algoma Steel.
Defense Metals is focused on the development of its wholly owned Wicheeda Rare Earth Project located near Prince George, British Columbia, Canada, while Hanwha is a South Korean global premium specialized shipbuilding and offshore contractor in the design, construction, maintenance and marketing of all types of vessels, offshore platforms, drilling rigs, floating oil production units, and submarines.
Montage Gold: West Africa Expansion as Koné First Pour Approaches
Six months after it acquired African Gold, Montage is consolidating its Didievi project and preparing to upgrade the resource in the third quarter, with plans to pour first gold later this year at its main Koné project in Cote d'Ivoire.
At its Didievi project, about 300 km southeast of Koné, a 40,000-metre drilling program is expected to wrap up in the coming weeks, with Didievi hosting 12.4 million inferred tonnes grading 2.5 grams gold per tonne, for 989,000 ounces.
Koné, located 470 km northwest of the country's financial capital Abidjan, has a net present value of $1.1 billion, at a 5% discount rate, with a 31% internal rate of return, and could produce 349,000 oz. annually during its first three years at an all-in sustaining cost of less than $1,000 per oz.
Montage CEO Martino de Ciccio said "The goal for us is to build a multi‑asset company focused on Africa," noting that smaller junior companies wanted to partner with Montage instead of partnering with established producers in the area.
The company's expansion comes as West Africa's Sahel region faces increased resource nationalism, with Côte d'Ivoire emerging as a more stable jurisdiction for mining investment.
What It Means
Today's announcements reveal three powerful forces reshaping the mining sector: geopolitical realignment, supply chain vulnerabilities, and the race to secure critical minerals for the energy transition.
The Quad's $20 billion commitment represents more than capital — it's a strategic pivot away from China-dominated processing networks. With rare earth separation, lithium refining, and battery manufacturing concentrated in Chinese hands, Western allies are finally mobilizing the scale of investment needed to build parallel supply chains. The inclusion of recycling and processing alongside mining signals a more sophisticated approach than previous initiatives.
The sulphuric acid crisis exposes a dangerous dependency. When a single chemical input — largely a byproduct of oil refining — can threaten half of global lithium, cobalt, and rare earth production, the energy transition faces a structural bottleneck.
The supply squeeze highlights how geopolitical conflict is increasingly colliding with energy transition supply chains, with countries possessing domestic sulphur and acid production capacity, such as the US, likely to be more insulated than import-reliant jurisdictions.
Meanwhile, project approvals and partnerships continue to advance. Minera Alamos' Arizona gold project, RZ Resources' NSW critical minerals mine, and Defense Metals' Hanwha MOU all demonstrate capital flowing toward jurisdictions with stable regulatory frameworks and strategic alignment with Western supply chain goals. Cameco's swift recovery from flooding disruptions reinforces the resilience of Tier 1 uranium producers in a market where nuclear power is gaining renewed support.
The common thread: mining companies aligned with Quad nations, producing strategic commodities, and operating in stable jurisdictions are attracting capital and partnerships at an accelerating pace. The era of purely commercial mining deals is giving way to transactions with explicit geopolitical dimensions — and investors are taking note.
