Pilot Mountain pre-feasibility study

Drilling at Tempiute began in autumn 2025, and the company bought Lincoln Estates for US$1.3m on 17 Jun 2026, securing water rights and land. On 21 Sep 2026 it reported first Phase II assays (92.0m @ 0.34% WO3) and completed Phase I. It decided to rehabilitate the underground workings, with works expected from October 2026.
