SPARTAN METALS COMMENCES MAIDEN DRILLING PROGRAM AT ITS EAGLE TUNGSTEN-SILVER-RUBIDIUM PROJECT, NEVADA

Spartan Metals Corp. has commenced drilling at its 100-per-cent-owned Eagle tungsten-silver-rubidium project in Nevada.

Highlights:

• Up to 3,000 metres of diamond core drilling currently under way;
• Three primary targets to be tested in 2026:
  • The Southeast tungsten anomaly with tungsten skarn potential;
  • The tungsten-silver-rubidium vein system defined from recent surface exploration;
  • New high-potential targets defined through IP (induced polarization) geophysics;
• Fully financed from existing working capital raised in early 2026;
• Advances the second of Spartan's two U.S. tungsten projects, alongside the Victorio tungsten-molybdenum project in New Mexico that has a coming PEA (preliminary economic assessment) update in Q4 2026.

Brett Marsh, Spartan's president and chief executive officer, stated: "This a very exciting moment for Spartan and the Eagle project. We have done a significant amount of fieldwork leading up to this point and we are thrilled to have drills turning at Eagle, which hasn't seen any real exploration work since World War 2, when tungsten was a critical mineral for the war. Tungsten is vital to U.S. defence, advanced manufacturing and technology sectors, but the U.S. remains dependent on non-allied imports. The July 20 presidential executive order makes the national imperative clear that the U.S. must secure domestic supply chains for critical minerals. Eagle provides an excellent opportunity to explore and potentially develop a U.S. source for tungsten in Nevada. We are very eager to see the results from this maiden drilling program at Eagle, which will be out later this year."

Drill program details

The current program consists of approximately 3,000 m of core drilling to test high-priority targets across the Tungstonia claim block that have been identified and refined through surface exploration and geophysical surveys. The primary objective of the program is to evaluate the depth and continuity of the tungsten-silver-rubidium vein mineralization and to investigate the tungsten skarn potential adjacent to the veins while advancing the company's understanding of the broader mineral system.

Initial drill results will be released as assays become available.

About the Eagle tungsten-silver-rubidium project

The Eagle project presents a unique opportunity to delineate one of the largest and highest-grade tungsten and rubidium districts in the United States. Eagle consists of the past-producing, high-grade Tungstonia, Yellow Jacket and Rees/Antelope tungsten (tungsten-copper-silver) mines. Operations at these mines were from 1915 to 1942, with intermittent small-scale production occurring until 1956. Tungsten production from these mines totalled 8,379 units at grades between 0.6 per cent and 0.9 per cent WO3 (tungsten trioxide).

Eagle is approximately 36.5 square kilometres in size and located approximately 120 kilometres northeast of the town of Ely, in the Kern Mountains of White Pine county, Nevada. The project covers 9,033 acres, consisting of 445 Bureau of Land Management (BLM) unpatented lode mining claims.

Three deposit types are present at Eagle -- porphyry, skarn and carbonate replacement deposit (CRD) -- that contain significant or anomalous grades of tungsten, silver and rubidium plus copper/antimony plus or minus gold/lead/zinc/bismuth/arsenic across three project focus areas that also includes the potential to recover tungsten/rubidium/silver from the legacy Tungstonia mill tailings.

About Spartan Metals Corp.

Spartan Metals is focused on developing critical minerals projects in well-established and stable mining jurisdictions in the Western United States, with an emphasis on building a portfolio of diverse strategic defence minerals such as tungsten, rubidium, antimony, bismuth and arsenic.

Spartan's high-quality project portfolio includes an option to earn 100 per cent of the Victorio tungsten-molybdenum project in New Mexico and the 100-per-cent-owned Eagle tungsten-silver-rubidium project in Nevada. Victorio hosts one of the largest tungsten resources in the United States and contains significant concentrations of beryllium and fluorspar, while the Eagle project consists of one of the highest-grade historic tungsten resources in the United States, including significant underdefined resources consisting of high-grade silver, rubidium, antimony, bismuth, indium, as well as precious and base metals.
