According to a report by Bloomberg on Mining.com, the US Department of Defense (DoD) invested $18 million in Canada's 5N Plus Inc. to help the company expand its germanium metal refining capacity. Germanium is used in night vision systems and other application fields.

Mike Cadenazzi, a Pentagon official, stated in an announcement regarding the deal, "Our warfighters rely on next-generation optical technologies for surveillance, reconnaissance, and targeting, and germanium is a critical material for manufacturing these devices."

The US has been seeking secure supplies of critical minerals to reduce risks and external dependencies. Since 2024, the US has invested over $60 million in Canadian small and medium-sized enterprises producing these materials, including Nano One Materials Corp, which produces LFP battery cathode materials, and other enterprises producing graphite and tungsten.

Since 2020, the DoD has been collaborating with the company to improve semiconductor production processes needed for space programs and to produce germanium wafers for solar cells used in defense and commercial satellites.

Over the past three years, the stock price of Montreal-based 5N Plus has increased by more than 650%. In November last year, management discussed several demand trends with analysts, including accelerated developments in solar energy and artificial intelligence, which are expected to drive demand growth this year.

The company, which began supplying materials for medical imaging in 2000, currently has a market capitalization exceeding C$2 billion ($1.5 billion).

5N Plus sources its germanium from Canada's Teck Resources Ltd., Europe's Umicore SA and Nyrstar NV, as well as scrap recyclers in the US. These materials are used to produce germanium wafers at the company's facility in St. George, Utah.

"This funding will enable 5N Plus to significantly increase its germanium metal refining capacity and support its plan to procure germanium from underutilized and previously untapped domestic sources," said Gervais Jacques, the company's CEO.

In September last year, Jacques revealed to Montreal's La Presse that the company plans to make a medium-sized acquisition in the US, followed by a smaller acquisition, to expand its manufacturing capacity.

Sinomine in Talks to Acquire Malawi's Kanyika Niobium Project from Globe Metals & Mining

[SMM Flash] Sinomine Resource Group is in talks to acquire Globe Metals & Mining’s Kanyika niobium development project in Malawi. The potential transaction would bring the Chinese critical-minerals group closer to a project it is already supporting through Sinomine International (Zambia) Engineering, which has been involved in early construction and development works at Kanyika. Globe began construction in January 2026 under a cost-reimbursable collaboration agreement, while first oxide production is targeted for the first quarter of 2028. Kanyika is positioned as a potential source of niobium and tantalum oxides, with Globe’s 2026 project plan targeting approximately 3,000 tonnes per year of Nb₂O₅ and 150 tonnes per year of Ta₂O₅ at full scale. Globe has previously retained full ownership and offtake rights while using Sinomine’s regional construction and processing expertise. Any acquisition would strengthen Sinomine’s exposure to niobium outside China and could add another strategic African critical-minerals asset to its expanding international portfolio.

Trekor Advances Aley Niobium Project with Optimised Processing and Commercial Focus

[SMM Flash] Trekor Metals on August 19 provided an update on its wholly owned Aley niobium project in northeastern British Columbia, reporting progress in its proprietary flotation process that has delivered higher niobium recoveries, improved concentrate grades and reduced reagent consumption. The company said the resulting concentrate has been successfully processed into market-grade ferroniobium, a key input for specialty steel production, while work is also underway to evaluate direct production of high-purity niobium oxide. Trekor has appointed Steve Sparkowich as Director, Aley Niobium, to support technical development, market positioning and commercial strategy. According to the company’s existing NI 43-101 technical report, Aley contains 84 million tonnes of proven and probable reserves grading 0.50% Nb₂O₅, with a planned processing rate of 10,000 tonnes per day and projected annual capacity of 14,000 tonnes of ferroniobium over a 24-year mine life. Following successful pilot testing and ferroniobium production, Trekor is now scaling up the programme and shifting its focus towards product marketing, potential offtake parties and processors. The company’s current update indicates continued progress towards commercial development, although the project remains subject to development, financing, permitting and other risks.

Criminal Networks Target Amazon’s Critical Minerals

[SMM Flash] Criminal organisations in the Amazon are increasingly positioned to expand from illegal gold mining into coltan, cassiterite, lithium, nickel, niobium and rare earth elements as demand grows for minerals used in batteries, semiconductors, defence, AI and clean-energy technologies. Existing networks controlling territory, clandestine airstrips, river routes and money-laundering channels can be adapted to support illicit mineral extraction and trade. In June 2026, Brazil’s Federal Police identified an illegal mining site in Pará where nearly 80 kg of gold was reportedly extracted over three years. The growing concern is that illegally sourced minerals can be mixed with legally mined material and laundered through forged documentation, intermediary companies and cross-border trade, making their origins difficult to detect. In April 2025, Colombian authorities seized nearly 49 tonnes of coltan and tin reportedly extracted from areas controlled by armed groups and destined for illegal export to China. Strengthening mineral traceability, financial intelligence, border controls and international cooperation will therefore be critical to protecting emerging critical-mineral supply chains from criminal infiltration.
