Mining Press Roundup: Cameco Halts Uranium Operations After Saskatchewan Floods

Flooding in northern Saskatchewan has disrupted supply routes to Cameco's McArthur River mine and Key Lake mill after the collapse of the Smoothstone River Bridge , forcing the world's second-largest uranium producer to temporarily halt operations at a critical moment for nuclear fuel markets. Cameco said the Cigar Lake mine continues to operate and its consolidated annual production plan remains unchanged , but the disruption highlights infrastructure vulnerabilities in Canada's remote mining regions as uranium demand surges.

Cameco: Saskatchewan Flooding Forces Uranium Production Halt

Cameco has temporarily halted production activities at Key Lake mill and reduced activity at McArthur River mine until the normal delivery of critical operating materials can resume , according to the company's operational update issued Monday. Uranium Equities analysts estimated the direct production impact could be about 1.5 million pounds of uranium if the Key Lake mill is down for a full month , as McArthur River's slurry tanks and mobile truck containers can hold only about seven to 10 days of full production .

Any production shortfall may force the company to buy or borrow uranium to meet commitments, potentially weighing on free cash flow, BMO analyst Alexander Pearce said . The timing is particularly challenging given tight uranium markets. According to market data, the URA uranium ETF traded down 6.7% on Monday as investors digested the supply disruption.

The timeline for the resumption of normal deliveries is currently unknown , Cameco stated, though Cigar Lake relies on a separate supply route that has not been affected by the Smoothstone River bridge collapse, meaning its production contribution remains intact . The Saskatchewan operation represents a substantial portion of global uranium supply, and disruptions at McArthur River could further tighten an already undersupplied uranium market and support spot uranium prices , according to BMO's analysis.

Barrick Gold: $3 Billion Buyback Sets Stage for North American Spinoff

Barrick Mining launched a $3-billion share buyback on Monday as the world's third-largest gold producer seeks to attract investors ahead of a planned spinout of its North American assets . The Toronto-based miner announced the repurchase authorization after net earnings rose to $1.6 billion, more than triple year-earlier levels, despite gold production declining 5% to 719,000 ounces .

Barrick is preparing to list a new company holding its Nevada joint venture, the Fourmile discovery and the Pueblo Viejo mine in the Dominican Republic by the end of 2026 , according to the company's announcement. The authorization is intended to return cash to shareholders at a time when Barrick sees exceptional value in its own shares, particularly in anticipation of the planned IPO of North American Barrick , the company stated.

BMO analyst Matthew Murphy said Barrick's results reflected a strong start to the year, with free cash flow of almost $1.6 billion beating estimates . Gold traded at $4,767 per ounce on Monday according to market data, up 1.6%, providing a favorable backdrop for the buyback. The company's average realized gold price climbed 66% year-over-year to $4,823 per oz., while all-in sustaining costs fell 4% to $1,708 per ounce .

TMC and Allseas: First Commercial Deep-Sea Nodule Mining Deal

The Metals Company has signed a commercial agreement with offshore engineering giant Allseas to develop and operate what the companies say would be the world's first commercial deep-sea nodule recovery system . The planned system would have nameplate production capacity of 3 million wet tonnes annually, using two collector vehicles that will operate more than 4 km below the ocean surface in the Clarion Clipperton Zone of the Pacific Ocean.

Drawing on more than four decades of offshore engineering experience and the successful 2022 pilot nodule recovery test in which 3,000 tonnes of nodules were lifted to the surface, Allseas will complete the procurement, integration and operation of what the Company expects will be the world's first commercial nodule production system . Tendering and vendor engagement are expected to begin soon, with subcontract awards targeted by the end of the third quarter of 2026 .

Under the new Agreement, Allseas will fund a significant portion of development costs, recoverable through production revenues, further aligning both parties around successful commercial operations , according to TMC. TMC anticipates system commissioning will begin in Q4 2027, subject to receipt of required permits and regulatory approvals . The polymetallic nodules contain nickel, copper, cobalt, and manganese—critical minerals for electric vehicle batteries and clean energy infrastructure.

Fortescue: $108 Million Penalty for Indigenous Site Damage

Fortescue Ltd., one of the world's biggest iron ore miners, has been ordered to pay over A$150 million ($108 million) in damages to an Aboriginal group after being found to have operated the Solomon Hub project on their land without consent . The decision marks one of the largest ever payouts in Australia's history brought under native title laws recognising Indigenous rights and interests in certain parcels of land .

Federal Court of Australia Judge Stephen Burley ruled Fortescue caused "significant damage" to the cultural heritage of the Yindjibarndi people of Western Australia, concluding that the miner was liable to pay A$150 million in compensation for cultural loss and A$100,000 for economic loss . The Yindjibarndi people brought a claim against the miner and the Western Australian state government for A$1-billion in cultural loss and in excess of A$800-million in economic loss , though the court awarded significantly less.

The Solomon Hub Project had prevented the Yindjibarndi from accessing more than 135 square kilometres of their land, which had been fenced off because it was "too dangerous to enter" due to mining infrastructure including open-pit mines, a railway, a tailings dam and waste dumps, and the mining activity also destroyed many heritage sites , according to the judgment. The ruling sets a significant precedent for Indigenous compensation claims in Australia's mining sector.

Focus Graphite: Quebec Resource Ranks Fifth-Largest Globally

An updated resource for Focus Graphite's Lac Tetepisca project in central Quebec ranks it in the top five largest graphite resources in the world, and almost doubles its contained graphite over the initial estimate . The update boosts the global contained graphite to 14.7 million tonnes over the 2022 resource, an 86% increase, while the total grade of 10.2% graphitic carbon (Cg) is just slightly lower than the 10.7% Cg in the original estimate , Focus reported Thursday.

Focus CEO Dean Hanisch said "Lac Tetepisca delivers on all three" requirements of scale, size, and grade needed to be "a credible and serious alternative source of supply to China, particularly in building a secure domestic North American supply chain," adding that "while operating costs in Canada are inherently higher than in China, grade is the key equalizer" . Lac Tetepisca is about 800 km northeast of Montreal .

The resource update places Lac Tetepisca in fifth place globally for total contained graphite, with Triton Minerals' Balama North/Nicanda Hill project in Mozambique leading the pack with 41.7 million tonnes contained graphite, and Sarytogan Graphite's namesake project in Kazakhstan second with 36.3 million tonnes . The resource milestone further positions Quebec as one of the world's top emerging graphite development hubs , with graphite demand surging for electric vehicle batteries.

Ionic Rare Earths: Recycled Supply Chain Demonstration for EV Motors

Ionic Rare Earths claims a "Western world first" by producing recycled neodymium, dysprosium, and terbium oxides that became Ford-tested EV motor magnets, with the recycled rotor performing comparably to conventional materials in durability testing . The Belfast-based project demonstrates a complete rare earth recycling supply chain involving Less Common Metals, GKN Powder Metallurgy, and Ford UK.

Backed by £11 million in UK Government funding for its CirculaREEconomy project, the company is scaling up to redefine the circular economy in automotive magnet production . Thomas Kelly, Director of Operations, explained that "our technology utilises a long-loop process, which means that we produce rare earth oxides that are identical to material produced via mining and refining" .

By 2030, Belfast is expected to produce at design capacity, supplying 400 tonnes of recycled rare earth oxides annually . The demonstration is significant because it demonstrates the full chain—from recycled oxides to high-purity separation (99.87% Nd₂O₃, 99.56% Dy₂O₃) to strip-cast alloys to qualified magnets—addressing chemistry bottlenecks China has long dominated . The project addresses Western supply chain vulnerabilities as China controls over 90% of global rare earth processing.

80 Mile: Greenland Drilling Permits Secured for Nickel-Copper Project

An initial 5,000‑metre drill program is scheduled for the first week of July at Disko-Nuussuaq nickel-copper-cobalt-PGE project in West Greenland , according to 80 Mile's announcement. The company has obtained drilling permits from Greenlandic authorities and approved a US$7.5 million budget for an initial 5,000-metre drilling programme scheduled to begin in July 2026 .

Disko is recognised as a world-class geological setting for copper, nickel, cobalt and PGEs, with potential for a Tier-1 nickel-copper discovery analogous to Siberia's Norilsk Nickel District . Seven significant Magmatic Massive Sulphide targets have been identified to-date at the licence area, with the largest being confirmed now at 5.9 kilometres long by 1.1km wide .

In late 2025, the company entered into a JV agreement with USFM Corporation under which USFM will fund US$30 million in drilling-related expenditure, including US$10 million in spring/summer 2026, to accelerate drilling and resource definition at Disko . The project targets critical minerals essential for electric vehicle batteries and clean energy infrastructure, with Greenland emerging as a strategic jurisdiction for Western supply chains seeking alternatives to Chinese-dominated markets.

What It Means

Today's announcements reveal three major themes shaping the mining sector: supply chain disruption, capital deployment, and the race to secure critical minerals outside China's orbit.

Cameco's Saskatchewan flooding demonstrates how climate-related infrastructure failures can ripple through global commodity markets—particularly in uranium, where supply is already tight and nuclear power is experiencing a renaissance. The incident underscores the fragility of remote mining operations dependent on single-route logistics, a vulnerability that will likely drive infrastructure investment across Canada's north.

Meanwhile, Barrick's massive buyback and TMC's deep-sea mining deal signal that capital is flowing toward both established producers with strong cash generation and frontier technologies promising new supply sources. The $3 billion Barrick is returning to shareholders reflects the windfall from record gold prices—gold traded above $4,700 per ounce Monday according to market data—while TMC's Allseas partnership represents the first serious attempt to commercialize seabed mining for battery metals.

The Focus Graphite resource update, Ionic's rare earth recycling demonstration, and 80 Mile's Greenland drilling permits all point to the same strategic imperative: Western economies are racing to build alternative supply chains for critical minerals. Quebec graphite, Belfast-recycled rare earths, and Greenland nickel-copper all offer pathways to reduce dependence on Chinese processing and refining—a geopolitical priority that's driving both government funding and private capital into junior miners and technology developers. Whether these projects can scale to commercial production fast enough to meet surging EV and clean energy demand remains the defining question for the sector.
