Pulsar Helium has bought 1,360 acres of surface land at its 100%-owned Topaz project in Lake County, Minnesota, from Wolf Lands Inc. for $2.48 million, securing the JS#7 (Jetstream #7) well site and other key infrastructure locations directly above its leased mineral rights. The company now controls surface access over the core discovery area as it tenders for up to four new production wells to complement two production-ready wells, supported by newly enacted Minnesota helium-specific permitting legislation signed on 26 May.

Military Metals’ share price fell as much as 60% to C$0.16 after Slovakia’s Ministry of the Environment revoked its exploration licence for the Trojarova antimony-gold project near Bratislava, which the company says was cancelled “without appropriate justification”. Trojarova, interpreted as a continuation of the historic Pezinok mine, carries a Soviet-era resource of 415,000 tonnes grading 0.162% Sb and 1.148 g/t Au based on underground exploration. The licence had been within Slovakia’s designated exploration areas under the EU critical raw materials framework, raising questions over regulatory risk for antimony supply projects in the region.

New drilling at Group Eleven Resources’ PG West project in Ireland has extended high-grade mineralisation at the Ballywire discovery, with hole 26-3552-57 cutting 62.5 m from 329 m depth grading 2.9% Zn, 2.7% Pb and 25 g/t Ag, including 11.8 m at 3.3% Zn, 10.1% Pb and 45 g/t Ag. Backed by C$12 million raised in March from investors including Glencore (13% stake) and Michael Gentile (14%), the company has expanded its PG West drilling campaign from 20,000 m to 67,000–75,000 m using four rigs. Mineralisation comprises sphalerite, galena and pyrite with local chalcopyrite and suspected tennantite-tetrahedrite, now traced along a ~1.5 km massive sulphide corridor.
