Mining Press Roundup: Sweden Greenlights Europe's Rare Earth Hope as Critical Minerals Take Center Stage

Leading Edge Materials secured a 25-year mining lease from the Swedish government for its Norra Kärr heavy rare earths project , marking one of Europe's most significant critical minerals decisions in years. The project's strategic importance to Sweden and the EU was a decisive factor in the government's decision, with the Geological Survey of Sweden confirming that Norra Kärr is one of Europe's richest rare earth elements deposits . The approval comes as Europe seeks to reduce its near-total dependence on Chinese rare earth imports, with Europe currently operating no rare earths mines .

Leading Edge Materials: Sweden Grants 25-Year Rare Earths Concession

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 Norra Kärr deposit is particularly valuable for its concentration of heavy rare earths—dysprosium, terbium, and yttrium—which are essential for permanent magnets used in electric vehicles, wind turbines, and defense applications.

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 , according to Leading Edge CEO Kurt Budge. A 2021 preliminary economic assessment projects a 26 year mine life producing an average of 5,340 metric tons of mixed rare earth oxides annually . The timing is critical: Following Chinese export controls in 2025, European dysprosium prices surged to $950 per kilogram from $280, terbium reached $4,000 per kilogram, and yttrium oxide reached $270 per kilogram in Europe compared to a Chinese price of $11 .

Shares of Leading Edge Materials soared nearly 28% following the announcement, taking the company's market capitalization to approximately C$85 million .

Fortuna Mining: $1B Senegal Gold Project Advances Africa Growth

Fortuna Mining announced positive results from the feasibility study for its Diamba Sud Gold Project in Senegal, confirming a 9.4-year open-pit, carbon-in-leach mine design with robust economics . The feasibility work indicates an after-tax net present value of roughly $1 billion at a $3,500 per ounce gold price, with a 60% internal rate of return and a one-year payback .

The project represents a significant upgrade from previous studies. The study outlines total initial capital of about $398 million, projected life-of-mine gold production of 1.05 million ounces, and average annual output of 158,000 ounces in the first four years at an all-in sustaining cost of $1,056 per ounce . Together with the Séguéla mine expansion, Diamba Sud supports Fortuna's plan to grow its annual gold production rate by approximately 60% to more than 500,000 ounces in 2028 , according to President and CEO Jorge Ganoza.

The Certificate of Conformity for the environmental and social impact assessment was received on June 11, 2026, representing a key milestone in the permitting process, with Fortuna having approved an early works budget of $73 million to de-risk the development schedule . With gold trading at $4,014 per ounce according to market data, the project's economics have strengthened considerably since the feasibility study's base case assumptions.

Generation Mining: Marathon Copper Project Nears $1B Funding Close

Generation Mining has assembled almost all its financing for the $1-billion capex Marathon copper-palladium project in northern Ontario . The $969 million total includes $200 million this week from the Canadian Infrastructure Bank, $424 million in senior debt from several lenders and a $240-million streaming deal with Wheaton Precious Metals .

Marathon, located on the north shore of Lake Superior, would be one of Ontario's first critical minerals projects to enter production in years with its planned 2028 start, and would be one of North America's few sources of palladium for hybrid and electric vehicles, and a top-five copper producer in the province . In addition to the copper, it would annually produce 168,000 oz. of palladium, 38,000 oz. of platinum , plus gold and silver over its 13-year life.

Generation Chairman Kerry Knoll noted it's "really, really rare that a company with a $200-million market cap is attempting to build an almost $1-billion capex mine" . That leaves about $150 million to be potentially raised through equity this fall, according to Haywood Securities mining analyst Pierre Vaillancourt . With copper trading at $6.30 per pound according to market data—well above the feasibility study assumptions—the project's economics remain compelling.

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 . 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 .

That increase is aided by the 130% rise in the gold price since 2023, with the feasibility also lifting the internal rate of return by 12 percentage points to 34% and mine life by four years to 15 years . At a base case of $3,650 per ounce, the study demonstrates strong economics, including a post-tax NPV of $696 million, a post-tax internal rate of return of 34.4% and a rapid payback period of 2.5 years .

Freeman CEO Bassam Moubarak said the project generates more than two dollars of post-tax NPV for every dollar of initial capital invested, underscoring its capital efficiency, and the feasibility now puts Lemhi in a small group of advanced gold development projects in Idaho . Freeman shares jumped almost 20% to 34¢ apiece, their highest level in one month, giving the company a market capitalization of $93 million .

Bunker Hill Mining: Idaho Silver Mine Ships First Concentrate in 45 Years

Bunker Hill Mining announced the production of concentrate from the new Bunker Hill Mine in Idaho's prolific Silver Valley, marking the first product shipped in 45 years from a mine that produced 165 million ounces of silver and 4.5 million tonnes of base metals before it closed in 1981 . The restart represents a pivotal milestone for the historic Silver Valley district.

It marks a pivotal milestone for both the Silver Valley community and the business following six years of careful redevelopment, infrastructure modernization, permitting, financing, and underground rehabilitation by the revitalized company under its new management team . The company expects to be at commercial production—defined as achieving 90 days at greater than 65% of 1,800 tonnes per day throughput and associated operating stability—by the end of 2026 .

The mine's restart comes as silver prices have strengthened considerably, trading at $58.41 per ounce according to market data. Recent underground drilling has focused on high-grade silver-lead mineralization near existing infrastructure, with 16 core holes totaling 5,960 feet all intersecting visible galena mineralization .

REalloys: US Army Site Selection and $100M Raise

REalloys is raising $100 million through a securities purchase agreement with institutional investors and the U.S. Army selected it among companies to build processing plants on military bases . REalloys was selected to negotiate an enhanced-use lease at the Tooele Army Depot in Utah, where it plans to build processing facilities for heavy rare earth elements including dysprosium and terbium, metals used in high-temperature permanent magnets for defence and industrial applications .

The selection marks what the Army describes as the first commercial critical-mineral processing award on a U.S. military installation under Executive Order 14241 . The move reflects growing U.S. government urgency to secure domestic critical minerals supply chains. In support of those plans, REalloys signed a 15-year offtake agreement last month for rare earth concentrates to be produced at Critical Metals' Tanbreez project in Greenland, hailed as one of the largest and most significant heavy rare earth deposits globally .

The financing and Army selection position REalloys to accelerate its vertically integrated rare earth magnet supply chain, from upstream resource development through midstream processing to downstream manufacturing.

Martin Marietta: $13.5B Lhoist Merger Creates Aggregates Giant

Martin Marietta Materials announced that it has entered into a definitive agreement to combine with Lhoist North America, a subsidiary of Lhoist Group, for $13.5 billion in cash and shares of Martin Marietta common stock . Martin Marietta says the acquisition of LNA—from Belgium-based Lhoist Group—immediately makes it the leading US national producer of lime solutions .

Lhoist North America is a leading producer of hi-calcium lime, dolomitic lime and industrial mineral products, serving a diversified set of end markets such as domestic steel manufacturing, infrastructure and heavy non-residential construction, environmental and agricultural applications . The transaction is expected to be completed in the second half of 2026, subject to regulatory approvals .

The deal represents a major consolidation in the aggregates and industrial minerals sector, combining Martin Marietta's extensive quarrying operations with Lhoist's lime production capabilities. The transaction advances Martin Marietta's SOAR 2030 strategic objective to expand its complementary specialty platform with what the company describes as "aggregates-like" characteristics—depleting natural resources with high barriers to entry and strong pricing power.

What It Means

Today's announcements reveal three powerful themes shaping the mining sector: the critical minerals arms race is accelerating, major project financing is flowing to advanced-stage assets, and consolidation is reshaping the industrial minerals landscape.

The rare earths sector is particularly active. Sweden's approval of Leading Edge Materials' Norra Kärr project and the U.S. Army's selection of REalloys for on-base processing both reflect Western governments' determination to reduce dependence on Chinese supply chains. With European dysprosium prices having tripled following Chinese export restrictions, the strategic imperative has never been clearer. These aren't speculative exploration plays—they're government-backed infrastructure projects designed to secure supply of materials essential to defense and the energy transition.

Meanwhile, the copper and gold sectors are seeing major projects cross the finish line on financing. Generation Mining's near-complete $969 million funding package for Marathon and Fortuna's billion-dollar Diamba Sud feasibility study demonstrate that institutional capital is available for quality assets in stable jurisdictions. The common thread: these are shovel-ready projects with strong economics, government support, and clear paths to production. Freeman Gold's tripling of Lemhi's value and Bunker Hill's first concentrate shipment in 45 years show that patient capital and disciplined execution can revive even long-dormant assets.

The $13.5 billion Martin Marietta-Lhoist merger signals that consolidation is extending beyond precious metals into industrial minerals, as major producers seek scale, reserve life, and exposure to infrastructure spending. In a capital-intensive industry facing permitting challenges and ESG scrutiny, size matters—and the biggest players are getting bigger.
