SPARTAN METALS PREPARES FOR 2026 DRILL AND EXPLORATION PROGRAM WITH GEOPHYSICS SURVEY AT THE EAGLE TUNGSTEN-SILVER-RUBIDIUM PROJECT, NEVADA

Spartan Metals Corp. has initiated its 2026 exploration program covering the Tungstonia claims at its 100-per-cent-owned Eagle tungsten-silver-rubidium project in Nevada.

Program highlights:

• Immediate implementation: surface sampling of soils and rocks over claims acquired in November, 2025, to potentially extend previously identified tungsten, silver and rubidium soil anomalies;
• Early June: ground geophysics surveys to inform depths of existing two-plus-kilometre tungsten-silver veins and potential tungsten skarn mineralization coincident with tungsten-silver-rubidium soil anomalies;
• Early to mid-July: Approximately 3,000 metres of diamond core drilling at high-priority targets identified through surface sampling and geophysics surveys.

Brett Marsh, Spartan's president and chief executive officer, stated: "We are very excited to kick off our 2026 exploration season at our Tungstonia claim block at our Eagle project. We are eager to understand the extent of potential mineralization and the results from these activities will be vital to developing and/or validating our core drilling targets. Each visit to the Tungstonia claims has increased our enthusiasm and optimism for significant discovery. We are keen to get drills turning and begin definition of the mineral system at Tungstonia."

Surface sampling program

The surface geology program will begin immediately and encompass the Tungstonia claims that were acquired in November, 2025, and will provide complete coverage of the Tungstonia claim block. The 2025 surface geology program defined two new exploration targets, with the southeasternmost target trending off the original claim boundary. The sampling will continue on the previous 100-metre-by-100-metre grid and will begin near the southeastern anomaly/target and progress toward the Yellow Jacket mine to the north and then conclude in the west and southern areas of the claim block.

Geophysics surveys

The geophysics surveys will be conducted by Quantec Geoscience Ltd. in early June and will consist of deep-penetrating Titan MT (magnetotelluric) and DCIP (direct-current induced polarization) surveys across the entire Tungstonia claim block. Titan distributed technology was developed by Quantec to provide deep accurate images of the subsurface while also delivering near-surface definition. By utilizing distributed technology, the system achieves the most accurate sampling of the subsurface. The DCIP survey provides an accurate rendering of the subsurface to depths of over 750 metres and will be combined with the Titan MT to define the lateral extent and depth of the tungsten-silver-rubidium veins at the surface. Titan MT survey provides a detailed rendering of the subsurface to depths of over 1,500 metres and provides a big picture of what is going on at depth, which may often be related to structures and other zones of mineralization that are consistent with vein and skarn-style mineralization.

Diamond core drilling

The Tungstonia claim block is currently permitted for up to 25 drill sites and the results from the surface sampling program and geophysics surveys will be used to refine and prioritize drill targets and define potential continuation of targets at depth. Approximately 3,000 metres of drilling are planned to begin immediately following completion of any drill target updates, which is anticipated for early to mid-July.

Quality assurance/quality control procedures

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 IO-4AB51 (51-element suite: 0.5-gram four-acid plus boric acid hot block, ICP-OES plus IM-4ABEx ICP-MS for rubidium. 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 and chief executive officer of Spartan Metals.

About the Eagle 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. The project 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).

The project 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 (CRD) -- which 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 include 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 the largest tungsten resource in the United States and contains significant concentrations of beryllium and fluorspar while the Eagle project consists of the highest-grade historic tungsten resource in the United States, which includes significant underdefined resources consisting of high-grade silver, rubidium, antimony, bismuth, indium,as well as precious and base metals.
