Spartan Metals confirms tungsten skarn discoveries at Eagle, Nevada

Vancouver, British Columbia--(Newsfile Corp. - June 23, 2026) - Spartan Metals Corp. (TSXV: W) (OTCQB: SPRMF) (FSE: J03) (" Spartan " or the " Company ") announces the confirmation of two tungsten skarn zones at its Tungstonia Claims within its 100% owned Eagle Tungsten-Silver-Rubidium Project, Nevada. Highlights: Skarn mineralization confirmed at past-producing Yellow Jacket Mine where historic production grades were approximately 1.12% tungsten trioxide ("WO 3 ") 1 (Figure 1) with two samples substantially above at 1.87% WO 3 and 1.67% WO 3 Rock sampling from within mine entrance and dumps delivered tungsten assays of 0.99% 1.87%, 0.89%, and 1.67% WO 3 and highlights 3.3% Zn and 1,320 ppm beryllium ("Be"), which has not been previously reported at the Eagle Project Backpack core drilling returned 0.3 meters (m) 0.21% WO 3 and 0.33% zinc (" Zn ") New tungsten-skarn discovery within the tungsten soil anomaly in southeast of project (SE Tungsten Anomaly) reported in December 2025 (Figure 1) Rock chip sampling returned 0.34% WO 3 and 1.9 g/t Ag and 144 ppm Be Backpack core drilling encountered previously unobserved molybdenum (" Mo ") mineralization (Figure 2) ranging between 0.01%-0.08% Mo along with significant rubidium ( "Rb" ) ranging between 1,122 – 2,122 ppm Rb and silver (" Ag ") ranging between 1.2-3.1 g/t Ag Molybdenum and beryllium mineralization along with significant tungsten and silver grades encountered over a length and width of approximately 2 kilometers (km), suggests multiple pulses of mineralization. Brett Marsh, Spartan's President and CEO stated, "The identification of a new tungsten-skarn occurrence within a previously defined tungsten soil anomaly marks an important exploration milestone at our Tungstonia claims and further validates our systematic targeting approach across the property.
