Spartan Metals Expands Past-Producing Tungstonia Mine Mineralization Footprint More Than 13-Fold, Defining 5.7 km2 of Tungsten-Silver Veins with Assays up to 5.18% WO3

· Issued by Spartan Metals Corp. via Newsfile

Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - Spartan Metals Corp. (TSXV: W) (OTCQB: SPRMF) (FSE: J03) ("Spartan" or the "Company"), an exploration and development company focused on tungsten and critical minerals in the western United States, is pleased to announce assay results from recent sampling conducted within its Tungstonia Claims at its 100% owned Eagle Project, Nevada (Figure 1).

Highlights:

  • 8 confirmed tungsten-silver veins over a total area of approximately 2.7 kilometers ("km") by 2.1 km (~5.7 km2) and have a cumulative surface strike length of approximately 6.8 km (Table 1 and Figure 3) which represents an approximate 13x increase in defined mineralization since Spartan acquired the Eagle Project in July 2025 (Figures 2 and 3)

  • Vein 4 has been extended 400 meters ("m") southward along strike by rock samples 5.18% WO3 to a total confirmed length of approximately 1.1 km

  • New vein ("Spartan C") confirmed between Veins A and B at approximately 700 m length (Figures 2 and 3) with rock samples of 3.67% and 2.72% WO3

  • Spartan B Vein has been extended 530 m with rock samples of 1.82% and 2.43% WO3 to a total confirmed length of approximately 700 m (Figures 2 and 3)

  • Spartan A Vein has been extended approximately 500 m via alteration mapping coinciding with tungsten in soil anomaly (Figures 2 and 3)

  • Approximately 50% of Tungstonia Claims remain to be explored

All veins strike between N10E to N20E and dip 50 to 65 degrees east. True widths are reported where known

Brett Marsh, Spartan's President and CEO, stated, "When Spartan acquired the Eagle Project in July 2025, the known extent of mineralization at Tungstonia covered an area of approximately 750 meters by 550 meters. Our 2025 and 2026 field programs have now defined eight tungsten-silver veins across an exploration footprint measuring approximately 2.7 kilometres by 2.1 kilometers-an increase of more than 13-fold-with a cumulative exposed surface strike length of approximately 6.8 kilometers."

Mr. Marsh continued, "What is most encouraging to us is that the mineralized system continues to grow each time our team returns to the field. We are not simply extending a single known vein; we are identifying additional structures and seeing strong tungsten assays recur across multiple targets. This is giving us a much clearer picture of how mineralization is distributed across Tungstonia and reinforces the effectiveness of the exploration approach our team has taken."
