Lassonde-backed Cadillac Mines reports infill drilling at the Kerr-Addison project in Ontario, with standout hole KAD26-428T cutting 23 m at 3.08 g/t gold from 259 m, including 6.4 m at 5.26 g/t, and KAD26-397 returning 38 m at 2.13 g/t from 192 m, supporting a larger open-pit resource case. The company is about two-thirds through a 17,850 m infill programme within the current pit shell, part of a 145,000 m, C$65 million 2026 drilling budget using 11 diamond rigs. Kerr-Addison currently hosts 78.5 Mt indicated at 1.34 g/t (3.38 Moz) and 25.9 Mt inferred at 2.66 g/t (2.21 Moz), with new drilling targeting lesser-tested footwall zones and step-outs northeast of existing blocks.

An initial mineral resource at American Tungsten’s Ima project in northeast Idaho defines 316,000 indicated tonnes at 0.55% WO₃ (1,747 tonnes WO₃) plus 404,000 oz silver, and 2.1 million inferred tonnes at 0.55% WO₃ containing 11,933 tonnes WO₃ and 1.8 million oz silver, making it Idaho’s highest-grade primary tungsten project. The estimate also includes 267,000 tonnes of historical surface tailings at 0.15% WO₃ (413 tonnes WO₃), supporting a Phase I tailings processing route alongside Phase II underground drilling, rehabilitation and restart planning. Based on 5,180 metres of recent drilling and historical data, the resource underpins work towards a preliminary economic assessment and positions Ima as a potential U.S. tungsten supply source amid Chinese export controls.

BHP and MIT spinout SiTration are piloting a chemical-free copper recovery technology at the historic Copper Cities mine in Arizona, targeting legacy mining water in a pit lake at a site that produced nearly 400,000 tonnes of copper between the 1950s and early 1980s. An initial one‑month pilot will validate continuous, autonomous production, followed by a larger two‑month deployment aiming to produce up to 2 tonnes of LME Grade A copper cathode. Bench tests using real site feedstock report sub‑3–4 kWh/kg energy use with no new waste streams, signalling potential low‑cost recovery from mining‑impacted waters across the US Southwest.
