Spartan Metals Corp. Discovers Two New Tungsten-Silver Veins At Tungstonia Claims Spartan Metals Corp. announced the discovery of two new tungsten-silver veins at its Tungstonia Claims within its 100% owned Eagle Tungsten-Silver-Rubidium Project, Nevada. Two new at surface quartz-huebnerite veins were discovered by backpack core drill sampling approximately 1 kilometer away from Vein 1, which was the primary production vein at the past-producing Tungstonia Mine. Tungsten-silver mineralization is identical to mineralization within Veins 1 through 5 at the Tungstonia Mine. A total of 7 tungsten-silver veins are now confirmed including the new Spartan A and Spartan B veins. Table 1 Backpack drill core assay results for Spartan A and Spartan B Veins. Vein ID Hole ID From (m) To (m) Interval (m) WO3% Ag (g/t) Spartan A STS-26-004 0 1.3 1.3 0.26 9.51 1.3 1.5 0.2 0.23 55.96 Spartan B STS-26-005 0 0.8 0.8 0.57 9.16. The discoveries, part of the exploration program announced on May 21, 2026, were confirmed utilizing a portable backpack diamond core drill with a 36.4-millimeter diameter core. The backpack drill is intended to rapidly evaluate potential veins and proposed drill locations prior to mobilization of larger diamond core drills. The vertical holes were located near potential vein locations interpreted from Spartan’s 2025 surface exploration programs and collared in greisen altered granite. True thicknesses/widths of mineralization are unknown as further definition is required to define the vein orientations. The drill results validate the presence of previously interpreted but unconfirmed veins at the Tungstonia claims and illustrate the potential for continued district scale discovery at the Eagle Project. The assay results are consistent with previously reported production grades at the Tungstonia and Yellow Jacket Mines of 0.6-0.9% WO3 and 1.12% WO3, respectively, which further illustrates the tungsten potential at the Eagle Project. This hole was collared approximately 850 meters west-northwest of the southern extension of Vein 1 and approximately 2 km south-southwest of the Tungstonia Mine and drilled to a depth of approximately 1.52 m. Quartz with huebnerite was encountered from surface and exhibited similar characteristics to the mineralization observed in Vein 1 near the Tungstonia Mine. Huebnerite crystals were approximately 1-2 centimeters in size. This hole was collared approximately 150m east of hole TS-26-004 and drilled to a depth of approximately 1.22 m. Quartz with huebnerite was encountered from the surface and contained 3-5 mm huebnerite crystals with multiple thin veinlets of huebnerite throughout the quartz. Spartan will continue to execute its 2026 exploration program as discussed in the May 21, 2026, announcement including: Continued surface sampling of soils and rocks – including continued backpack drilling – over claims acquired in November 2025 to potentially extend previously identified tungsten, silver, and rubidium soil anomalies; Mid-June: Ground geophysics surveys to inform depths of existing 2+ km tungsten-silver veins and potential tungsten skarn mineralization that is coincident with tungsten-silver-rubidium soil anomalies; Early to mid-August: Approximately 3,000 meters diamond core drilling at high priority targets identified through surface sampling and geophysics surveys. Samples were submitted to American Assay Lab (AAL) of Sparks, Nevada, which is a certified and accredited laboratory, independent of the Company. Samples are prepared using industry standard-prep methods and analyzed using method IM-4AB52 (52 element suite: 0.5g 4-acid plus boric acid hot block). AAL undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Spartan’s QAQC includes regular insertion of CRM standards, duplicates, and blanks with a stringent review of results completed by the Company’s Qualified Person, Brett R. Marsh, President and CEO of Spartan Metals. Recent Insider Transactions • Jun 10
