SPARTAN METALS PROVIDES ASSAY RESULTS AND PROJECT UPDATES FOR THE EAGLE PROPERTY

Spartan Metals Corp. has provided assay results and project updates for its recently closed acquisition of the Eagle property, announced on July 31, 2025. The Eagle property comprises 244 lode mineral claims in White Pine county, Nevada. The property is 100 per cent owned by the company.

The property is a tungsten-copper porphyry and skarn system that hosts one of the highest-grade past-producing tungsten districts in the United States, with the Tungstonia and Rees mine operations historically producing a reported 8,352 tonnes of tungsten trioxide (WO3) at average grades of 0.6 to 1.0 per cent between 1917 and 1956. The property also exhibits significant concentrations of rubidium, copper, silver, antimony, as well as lesser lead and zinc, which is interpreted as part of the larger metal zonation pattern of the porphyry system across the district.

William Pettigrew, Spartan's chief executive officer, commented: "We were excited to conduct field reconnaissance and rock chip sampling for the purposes of verifying historic data and results from Ridgeline Minerals Corp.'s 2024 rock chip sampling program, as well as testing mineralization at previously unreported locations at Tungstonia. The results confirm the historic and previous work, and provide new data approximately 200 to 400 metres down strike from historic production locations at Tungstonia."

Mr. Pettigrew continues: "These encouraging results validate historic and previous sampling and highlight the potential for the Eagle property to be a significant source of tungsten, rubidium, antimony, silver and copper in the future. We look forward to continuing field activities at the Tungstonia and Rees projects, and developing the project further."

Tungstonia project

Currently known tungsten mineralization occurs in five historically mined quartz-huebnerite (MnWO4) veins -- named veins 1 through 5 -- hosted in granite. A total of six rock chip samples were taken at Tungstonia. Three samples were intended to validate results obtained by Ridgeline Minerals (RDG) in 2024 at veins 1 and 2, which were the primary historically mined veins. The remaining three samples were focused on historically mapped but unsampled vein 3 and 4 locations. All samples were taken at surface.

Ridgeline results indicated 0.54 per cent WO3 and 13.5 grams per tonne (g/t) silver (Ag) at vein 1, and 1.49 per cent WO3 and 50.5 g/t Ag at vein 2. Spartan results for vein 1 were 1.97 per cent WO3 and 308 g/t Ag (TS-25001), and for vein 2 were 1.36 per cent WO3 and 31.9 g/t Ag (TS-25002) and 1.88 per cent WO3 and 12.5 g/t Ag (TS-25003). Spartan samples at both veins were taken within 10 metres (m) of the RDG samples and the resulting assays validate the previous work.

Veins 3 and 4 were sampled extensively via trenching by the U.S. Bureau of Mines (USBM) in about 1942 and associated surface mapping indicated these veins extended approximately 400 m to the southwest but did not have reported assays. Spartan's activities focused on testing the mapped but unsampled locations. Assays for vein 3 were 2.37 per cent WO3 and 9.6 g/t Ag (TS-25005), and 1.54 per cent WO3 and 0.9 g/t Ag (TS-25006), with the vein 4 sample returning 0.92 per cent WO3 and 5.1 g/t Ag (TS-25004). These samples clearly verify the historical and Ridgeline results, and further demonstrate the high-grade tungsten mineralization at the Tungstonia project.

QA/QC (quality assurance/quality control) procedures

Rock chip samples were taken by hand with rock hammer across veins to obtain an approximately two-kilogram sample. Samples were submitted to American Assay Lab (AAL), of Sparks, Nev., 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: 0.5-gram four-acid plus boric acid digestion/ICP-OES (inductively coupled plasma optical emission spectroscopy) or ICP-MS (inductively coupled plasma mass spectrometry) with 4AB ore grade for overlimit tungsten (W) samples) and IM-NFEx for W. AAL undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Spartan's QA/QC includes regular insertion of CRM (certified reference material) standards, duplicates and blanks with a stringent review of results completed by the company's qualified person, Brett R. Marsh, president, Spartan Exploration Nevada Corp..

About Spartan Metals Corp.

Spartan Metals is focused on developing critical minerals projects in top-tier 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 flagship project is the Eagle project in eastern Nevada, which consists of the highest-grade historic tungsten resource in the United States (the past-producing Tungsonia mine), along with significant underdefined resources, consisting of: high-grade rubidium; antimony; bismuth; indium; as well as precious and base metals.
