Several European lithium, rare-earth, tungsten, tin and gold projects recorded financing, corporate and exploration developments in July, spanning Germany, Sweden, the Czech Republic, Portugal and Cornwall.
AMG moves toward full Zinnwald ownership
Zinnwald Lithium shareholders approved AMG Critical Materials’ acquisition on 13 July 2026. AMG already owns 29.32% of Zinnwald and has offered 5 pence in cash plus 0.001577 new AMG shares per Zinnwald share, valuing the company at about £57.2 million and representing a 63% premium to the previous closing price.
Subject to court approval scheduled for 23 July, Zinnwald shares were expected to stop trading on 24 July, with the scheme becoming effective on 27 July and its AIM quotation cancelled on 28 July. AMG has provided more than £14 million to Zinnwald since 2023 and operates a lithium hydroxide refinery at Bitterfeld-Wolfen. Following completion, AMG plans another 18–24 months of technical work on the Zinnwald deposit, processing route and refinery integration, with phased development under consideration.
Leading Edge raises funds for Norra Kärr
Leading Edge Materials announced a proposed C$6 million private placement on 13 July, involving 24 million units at C$0.25. Each unit includes one share and a warrant exercisable at C$0.40 for two years. The financing follows Sweden’s 29 June decision to grant GREENNA Mineral a 25-year exploitation concession for the Norra Kärr heavy-rare-earth project.
Funds will support prefeasibility work and environmental permitting at Norra Kärr, alongside studies on a possible restart of the Woxna graphite mine and processing plant. Norra Kärr contains significant proportions of dysprosium and terbium. The concession does not permit construction, with environmental and other approvals still required. Based on approximately 258.8 million existing shares, the placement represents potential basic dilution of about 9.3%. Full warrant exercise could provide another C$9.6 million.
Cinovec kiln savings remain preliminary
European Metals Holdings clarified on 14 July that potential savings identified through preliminary testwork at the Cinovec lithium project are not yet part of its bankable economic case. Replacing two rotary kilns with one gas-and-electric tunnel kiln was estimated to reduce capital expenditure by approximately US$112 million and operating costs by US$10 million annually. Chemical-plant optimisation indicated potential additional annual savings of US$64 million.
The December 2025 DFS remains the governing study. It estimates construction capital of US$2.16 billion before grants, or about US$1.70 billion after approved support, with a pretax NPV of US$1.455 billion and a 14.8% IRR. Cinovec is designed to produce 37,500 tonnes of battery-grade lithium carbonate annually. European Metals owns 49% of Geomet, with CEZ holding 51%. A decision on the tunnel kiln is expected in the fourth quarter, with an updated DFS potentially targeted for the end of 2026.
Tungsten and tin drilling advances development studies
At Portugal’s Borralha tungsten project, Allied Critical Metals reported 81.5 metres grading 0.22% WO₃, including 23.8 metres at 0.68%, from its first 2026 Santa Helena drill hole. Borralha’s PEA envisages a 1.4 million-tonne-a-year underground operation, producing about 1,708 tonnes of WO₃ annually over an initial 11-year mine life. The study estimated an after-tax NPV of US$134 million, a 27.2% IRR and initial capital of approximately US$91 million.
Allied is conducting a 20,000-metre drilling programme using six rigs, with a seventh expected. At Cornwall’s South Crofty tin project, Cornish Metals intersected mineralisation beyond existing resource envelopes. Results included 0.79 metres at 4.18% tin, 0.30 metres at 2.20% and a 12.41-metre interval at 0.43% tin. The 2024 PEA estimated US$177 million in pre-production capital, an after-tax NPV of US$201 million, a 29.8% IRR and average production of approximately 4,728 tonnes of tin annually during years two to six.
