Ridgeline Minerals (OTCQB: RDGMF) has acquired an additional 5,000,000 common shares of Spartan Metals Corp. on July 31, 2026, as a second tranche under a June 2, 2025 share purchase agreement related to the sale of Spartan Exploration Nevada Corporation. The shares were issued for no additional cash consideration and form part of the original purchase price.
Following this issuance and prior share sales, Ridgeline now beneficially owns or controls 10,230,466 Spartan Metals shares, representing about 17.3% of Spartan’s outstanding common shares on a non-diluted basis.

Ridgeline Minerals (OTCQB: RDGMF) completed an all-cash sale of its Swift, Black Ridge, Bell Creek and Atlas gold exploration projects in Nevada to Nevada Gold Mines for US$23.15 million (C$32.71 million) under a purchase and sale agreement dated August 3, 2026.
According to Ridgeline, the deal closed effective August 3, 2026 and represents a 26% premium to its 20-day VWAP and more than 350% return on invested capital for the four projects. Post-transaction, Ridgeline reports a treasury of C$33.0 million in cash and C$3.0 million in marketable securities, while retaining its 97 km² Nevada exploration portfolio, including the Selena CRD project (funded by South32), Big Blue, Coyote and a 1% NSR on the Eagle tungsten project.

Before the Disposition, Ridgeline beneficially owned or controlled 5,380,466 Spartan shares, or about 10.77% of Spartan on an undiluted basis. After the sale, it holds 5,230,466 shares, or approximately 8.84%.
