Spartan Metals Corp. (“Spartan” or the “Company”) (TSX-V: W | OTCQB: SPRMF | FSE: J03), an exploration and development company focused on tungsten and critical minerals in the western United States, is pleased to announce that the United States Bureau of Land Management (“BLM”) has accepted the Company’s Notice modification authorizing seven additional drill pads at the Tungstonia Claims on its 100% owned Eagle Tungsten-Silver-Rubidium Project (“Eagle” or the “Project”) in White Pine County, Nevada, bringing the total number of authorized drill sites at Tungstonia to 32 (Figure 1).
The new locations were developed from the magnetotelluric (“MT”) and direct-current induced polarization (“DCIP”) surveys reported in the Company’s news release of September 17, 2026. Several of the new pads are designed to accommodate multiple holes at varying azimuths and inclinations from a single location to provide additional subsurface information without increasing surface disturbance.
Brett Marsh, Spartan’s President and CEO, stated, “When we permitted the original sites at Tungstonia we were working from mapping, surface geochemistry and the legacy workings. The geophysical results enhanced our geological interpretation of the system beneath those workings and throughout the Tungstonia Claims, and it identified new, high-priority targets. This Notice modification gives us the sites, and the flexibility let us drill where our data interpretation gives us the best chance for success.”
Highlights
- Seven additional drill sites authorized (Figure 1)
- Coverage across the diverse mineralization styles at Tungstonia (Figure 2and Figure 3). The sites test the vein depth extensions at Veins 1 through 5 and the Spartan A, B and C Vein complex, the SE Tungsten Anomaly, and the interpreted carbonate replacement and skarn targets defined by the geophysical surveys and surface geochemistry.
- Approximately 550 meters (“m”) of planned ~3,000 m core drilling program completed
Drill site locations were selected where the geophysical anomalies, mapped structure, quartz-vein and greisen development, and surface geochemistry coincide. Holes testing the vein set are planned at azimuths to cross the steeply dipping veins at high angle; holes testing the replacement-style targets are oriented to cut the interpreted contacts at depth. Drilling several holes from one pad allows Spartan to test more than one structure, or a single structure at more than one depth, without additional surface disturbance. Geophysical anomalies are not direct evidence of mineralization and can only be confirmed by drilling.
Status of Current Drill Program
Drilling is currently underway at Eagle with approximately 550 m of a planned ~3,000 m completed. The program will move onto the newly authorized sites to test the high potential areas identified through geological surface exploration and geochemical analysis in conjunction with the geophysical results. Assay results will be released as they are received, validated and interpreted.

Previously permitted drill sites are shown in green with newly permitted sites in yellow. Additional drill sites will be planned and permitted following results from the 2026 core drilling program.
Figure 2 Section A-A’ showing interpreted greisen alteration envelopes from 3D MT geophysical inversion between interpreted and mapped tungsten-silver veins. Greisen alteration is an excellent indicator of being in close proximity the source of tungsten mineralization. Knowing where the greisen alteration is or is interpreted in the case of geophysics helps predict tungsten vein locations and increases confidence in drill site locations. Greisen alteration often forms in a zone around a larger buried intrusion rather than in isolated fractures. The presence of greisen alteration at larger scale at Tungstonia suggests a larger mineralizing system is present.
Figure 3 Section B-B’ showing 3D MT inversion with interpreted geologic model. The potential porphyry target is prominent in the central portion of the section. This target is possibly the source (or one of the sources) of mineralization observed at Tungstonia due to its proximity to greisen alteration zones and favorable location in carbonaceous host rocks.

About The Eagle Tungsten-Silver-Rubidium Project
The Eagle Project is a district-scale exploration opportunity containing three past-producing tungsten mines (Tungstonia, Yellow Jacket and Rees/Antelope) with reported historic production grades of 0.6–3.51% WO31, and rubidium and silver mineralization identified in Spartan’s 2025–2026 sampling. 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 short ton units at grades between 0.6%-0.9% WO31
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
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 strategic defense minerals including tungsten, rubidium, antimony, bismuth and arsenic.
Spartan holds an option to earn 100% of the Victorio Tungsten-Molybdenum Project in New Mexico and owns 100% of the Eagle Tungsten-Silver-Rubidium Project in Nevada. Victorio is an advanced exploration project that hosts a 2012 historical mineral resource estimate of tungsten-molybdenum mineralization, with beryllium and fluorspar also present; an updated mineral resource estimate and preliminary economic assessment are in progress. Eagle is a district containing three past-producing high-grade tungsten mines (Tungstonia, Rees and Yellow Jacket) where Spartan’s sampling has also identified silver, rubidium, antimony, bismuth and indium mineralization. No mineral resource has been estimated at Eagle.
A qualified person has not done sufficient work to classify the Victorio historical estimate as current mineral resources or mineral reserves, and Spartan is not treating the historical estimate as current mineral resources or mineral reserves. See the Company’s news release of March 17, 2026 and www.spartanmetals.com for the source, date, parameters and reliability of the historical estimate.
