Spartan Metals commences maiden drilling at Eagle Tungsten-Silver-Rubidium, Nevada

Vancouver, British Columbia--(Newsfile Corp. - August 24, 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 that drilling has commenced at its 100% owned Eagle Tungsten-Silver-Rubidium Project (" Eagle " or " Project ") in Nevada.

Highlights:

Up to 3,000 meters ("m") of diamond core drilling currently underway

Three primary targets to be tested in 2026 (Figures 1-3): The SE Tungsten Anomaly with tungsten skarn potential

The tungsten-silver-rubidium vein system defined from recent surface exploration

New high-potential targets defined through IP geophysics

Fully funded 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 an upcoming PEA update in Q4 2026.

Brett Marsh, Spartan's President and CEO, stated, "This a very exciting moment for Spartan and the Eagle Project. We have done a significant amount of field work 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. defense, advanced manufacturing, and technology sectors, but the U.S. remains dependent on non-allied imports. The July 20 th 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 (Figures 1-3). 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 our understanding of the broader mineral system.

Initial drill results will be released as assays become available.

Cross section lines A-A' and B-B' coincide with recent geophysics lines. 2026 drill priorities are to test the SE Tungsten Anomaly, depth extension of Vein 1 with potential to delineate additional interpreted veins to the west, the potential southward extension of the Spartan A, B, and C Vein complex and high-potential near-surface geophysical anomalies. Multiple holes may be drilled from a drill site.

About The Eagle Tungsten-Silver-Rubidium Project

The Eagle Project presents a unique opportunity to delineate one of the largest and highest-grade Tungsten ("W") and Rubidium ("Rb") districts in the United States. Eagle consists of the past-producing 1 high-grade Tungstonia, Yellow Jacket, and Rees/Antelope tungsten (W-Cu-Ag) mines. Operations at these mines were from 1915 to 1942 with intermittent small-scale production occurring until 1956. Tungsten production from these mines totaled 8,379 units at grades between 0.6%-0.9% WO 3 1

Eagle is ~36.5 km² in size and located approximately 120 kilometers 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 (CRD) that contain significant or anomalous grades of Tungsten (W), Silver (Ag), and Rubidium (Rb) plus Cu-Sb±Au-Pb-Zn-Bi-As across three project focus areas that also includes the potential to recover W-Rb-Ag 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 defense minerals such as Tungsten, Rubidium, Antimony, Bismuth, and Arsenic.

Spartan's high-quality project portfolio includes an option to earn 100% of the Victorio Tungsten-Molybdenum Project in New Mexico and the 100% owned Eagle Tungsten-Silver-Rubidium Project in Nevada. Victorio hosts one of the largest tungsten resources in the United States 2 and contains significant concentrations of beryllium and fluorspar, while the Eagle Project consists of one of the highest-grade historic tungsten resources in the USA which includes significant under-defined resources consisting of: high-grade silver; rubidium; antimony; bismuth; indium; as well as precious and base metals, and more information about Spartan Metals can be found at www.SpartanMetals.com .
