Cameco: Cigar Lake Uranium Mine Suspended on Mill Disruption

Cameco today announced our Cigar Lake mine in northern Saskatchewan has temporarily suspended operations due to challenges at Orano's McClean Lake mill, where Cigar Lake ore is processed . Orano's McClean Lake mill has encountered operational challenges with its sulfuric acid plant that caused it to shut down in order to repair the issue .

With limited ore storage capacity at Cigar Lake, we have temporarily suspended mining activities until sufficient acid is available to allow milling to resume at McClean Lake. At present, we expect the McClean Lake mill to return to operation in approximately two weeks, and we do not expect the disruption to impact our 2026 production outlook for Cigar Lake . Cigar Lake, situated 70 km southwest of the mill, is the world's highest-grade uranium mine , and McClean Lake represents one of the world's largest uranium processing facilities, with an annual production capacity of 24 million lb. in concentrates . According to market data, uranium miners traded higher today, with the URA uranium ETF up 1.4% to $43.78.

Guardian Metal Resources: $660M Nevada Tungsten Project Advances

Guardian Metal Resources plc announced the results of the Pre-Feasibility Study for the Pilot Mountain tungsten project. The completion of the PFS marks a critical step in the Company's path towards the potential development of the first new United States based tungsten mining operation in over a decade . On an after-tax basis at base case tungsten pricing, this translates to a net present value of US$660.3 million at an 8% discount rate and an internal rate of return of 59.6% .

The Study results indicate that utilizing a conventional open-pit mining method and base case tungsten pricing, the Project is planned to produce 15,916 tonnes of WO3 over an 8-year mine life, generating after-tax free cash flow of US$1.058 billion, with a capital payback period of 1 year from first commercial production . The study, led by Guardian Metal with engineering partner Samuel Engineering and specialist consultants, is moving the project toward mine permitting and definitive feasibility work as part of efforts to deliver the first new hard-rock tungsten mine on U.S. soil in more than a decade . Key PFS workstreams are advancing on schedule, including completion of drilling for resource evaluation at the Desert Scheelite and Garnet Zones, open-pit mine planning, and drafting of a mine Plan of Operations targeted for submission to U.S. regulators in August 2026 .

Leading Edge Materials: Sweden Grants 25-Year Rare Earths Mining Lease

Leading Edge Materials announced that its wholly-owned Swedish subsidiary, GREENNA Mineral AB, has been granted an Exploitation Concession - 25-year mining lease - for the Norra Kärr Heavy Rare Earth Elements Project in Sweden . The Concession was granted by the Swedish Government following a formal recommendation from the Mining Inspectorate, which submitted the application to the Government for a final decision after all involved agencies had either endorsed the application or recommended approval. The project's strategic importance to Sweden and the EU was a decisive factor in the Government's decision .

The Geological Survey of Sweden has confirmed that Norra Kärr is one of Europe's richest rare earth elements deposits, with a particularly high proportion of the most valuable heavy rare earths . The Government's decision affirms that this is a strategically important heavy rare earth deposit, located in a Tier 1 jurisdiction, with the capacity to supply all of Europe's annual dysprosium requirements alongside meaningful terbium and yttrium production — materials that are indispensable to the energy transition and European industrial sovereignty . Europe currently operates no rare earths mines and relies almost entirely on imports. According to European Commission data, the EU consumes approximately 20,000 metric tons of permanent magnets annually, with 17,000 to 18,000 metric tons imported directly from China .

Koryx Copper: Namibia Drilling Wins Analyst Support

Koryx Copper provided further drill results for the Haib Copper Project in Southern Namibia, with best intersections including HM138: 584m @ 0.34% CuEq, HM149: 428m @ 0.35% CuEq, and HM153: 714m @ 0.31% CuEq . According to The Northern Miner, analysts at BMO Capital Markets and Red Cloud Securities say Koryx Copper is rapidly emerging as one of Africa's more attractive red metal development stories after the recent assays.

Haib is an advanced, large-scale open-pit sulphide Cu/Mo/Au porphyry project that is envisaged to produce at an average of 88,000tpa of Cu in concentrate over a 24-year mine life via a simple, scalable, open pit crushing/milling/flotation process . Preliminary Feasibility Study planned to be published during 4Q 2026 . According to market data, copper miners rallied today, with the COPX copper miners ETF surging 2.7% to $77.30.

Freeman Gold: Lemhi Feasibility Triples Project Value to $696M

A feasibility study for Idaho-focused Freeman Gold's Lemhi project raises its value threefold, increases mine life and establishes 1 million oz. of gold reserves compared to a previous economic study. Shares surged . The study gives Lemhi a post-tax net present value (discounted at 5%) of $696 million, a 227% increase over the preliminary economic assessment from 2023, Freeman reported Monday .

The feasibility also lifts the internal rate of return by 12 percentage points to 34% and mine life by four years to 15 years . Lemhi could produce 972,000 oz. over its life, at all-in sustaining costs of $1,718.95 per oz. and at a base case gold price of $3,650 per ounce . The feasibility now puts Lemhi in a small group of advanced gold development projects in Idaho, including Perpetua Resources' Stibnite, Liberty Gold's Black Pine and Integra Resources' DeLamar, in a state better known for its silver mines than gold . According to market data, gold traded at $4,035/oz today, up 0.7%.

Bunker Hill Mining: First Idaho Concentrate Shipped After 45 Years

Bunker Hill Mining announced the production of concentrate from the new Bunker Hill Mine in Idaho's prolific Silver Valley. This will be the first product shipped in 45 years from a mine that produced 165 Moz of silver and 4.5 Mt of base metals before it closed in 1981, after failing to meet the world-leading US environmental laws passed in the 1970s, resulting in the loss of 2,000 local jobs .

Bunker Hill Mining has started feeding ore through its rebuilt Idaho mill, moving the historical Silver Valley mine from construction to ramp-up after six years of redevelopment . The company has more than 20,000 tons of ore stockpiled at the crusher and plans to ramp mining towards the mill design level of 1,800 tons per day before reaching full production next year. At steady state, Bunker Hill expects about nine concentrate trucks a day to leave for Teck Resources' Trail smelter in British Columbia, 210 km north by road . According to market data, silver traded at $59.08/oz today, up 1.2%.

What It Means

Today's announcements reveal capital flowing decisively toward critical minerals and strategic metals. The South32-Alcoa mega-deal reflects consolidation in traditional base metals, while Guardian's tungsten PFS, Leading Edge's rare earths mining lease, and Koryx's copper drilling all underscore the intensifying race to secure supply chains for defense and energy transition metals.

Idaho is emerging as a gold and silver development hotspot, with Freeman's Lemhi feasibility and Bunker Hill's first concentrate shipment in 45 years signaling renewed momentum in a historically prolific mining state. Meanwhile, the Cameco suspension—though expected to be brief—highlights the operational interdependencies in complex uranium supply chains. With copper miners up 2.7% and uranium up 1.4% today, markets are rewarding companies advancing projects toward production in a supply-constrained environment.
