Vancouver, British Columbia--(Newsfile Corp. - July 7, 2026) - Spartan Metals Corp. (TSXV: W) (OTCQB: SPRMF) (FSE: J03) ("Spartan" or the "Company"), an exploration and development company focused on tungsten in the western United States, is pleased to announce assay results from recent sampling conducted at its past producing Rees Tungsten Mine ("Rees" or "Mine") located within the Rees Claims at its 100% owned Eagle Project, Nevada (Figure 1).
Highlights:
Rock chip samples from inside the Mine assayed at 6.76% and 3.75% tungsten trioxide ("WO")3, which are among the highest tungsten grades reported at the Eagle Project
Historic United States Bureau of Mines (USBM) sampling1 from within the Mine returned 8.48%, 1.50%, 0.83%, and 0.83% WO3
Historic USBM surface sampling1 at Rees returned 3.40%, 1.80%, and 1.46% WO3
Historic production records1 detail approximately 1,306 Short Ton Units (stu) or 1,185 Metric Ton Units (mtu) at an average grade of 3.51% WO3 was shipped in 1954 and 1955
The Rees Tungsten Mine is the third past producing tungsten mine at the Eagle Project where Spartan has validated reported historic tungsten grades that are in excess of 1% WO3, which suggests potentially significant tungsten endowment across the Eagle Project
Initial results confirm past producing grades and further support the belief that the Eagle Project represents one of the highest-grade tungsten districts in the United States
Brett Marsh, Spartan's President and CEO, stated, "The assay results from within the Rees Tungsten Mine are particularly exciting as they include some of the highest tungsten grades reported by Spartan Metals at the Eagle Project to date. Our sampling not only confirms the exceptional tenor of mineralization observed historically, but also closely aligns with historic United States Bureau of Mines sampling and documented production records. This independent validation continues to strengthen our confidence in the quality and reliability of the historical data across the Eagle Project."
Mr. Marsh, continued, "Perhaps most importantly, Rees is now the third past-producing tungsten mine at Eagle where we have confirmed historic tungsten grades that exceed 1% WO₃. When viewed alongside our recent results from Yellow Jacket and the newly identified tungsten skarn mineralization and new tungsten-silver veins at Tungstonia, a compelling picture is emerging of a large and well-endowed tungsten district with multiple styles of mineralization. We believe these results further demonstrate the exploration potential of the Eagle Project and reinforce our strategy of evaluating both historical producers and previously unexplored targets as we continue to advance the Eagle Project. These grades continue to support our team's interpretation that this project is one of the most prospective and highest-grade tungsten districts in the United States."
