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.

Deep Sea Minerals (CSE: SEAS) has applied to uplist to the Nasdaq, which would make it the third seabed exploration company on the exchange alongside The Metals Company (Nasdaq: TMC) and Odyssey Marine Exploration (Nasdaq: OMEX), pushing its share price to a record C$1.79 and valuing it at just over C$80 million. The Vancouver-based firm currently has no active projects but is targeting polymetallic nodule concessions in the 4.5‑million‑sq‑km Clarion–Clipperton Zone (3,500–6,000 m water depth) and the Cook Islands EEZ, where nodules are estimated at 21 billion tonnes and 6.7 billion tonnes respectively. For mining strategists, the move signals another capital-markets vehicle positioning early for potential future access to large-scale subsea nickel, cobalt, copper and manganese resources pending regulatory pathways in the Pacific.

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.
