Spartan Metals Drills Nevada Tungsten Site for First Time Since WWII

For the first time since World War II, a drill bit is turning at the Eagle tungsten project in Nevada. Spartan Metals Corp. (TSXV: W, OTCQB: SPRMF, FSE: J03) announced on 24 August 2026 that its maiden diamond core drilling programme is underway, putting the first modern holes into a property that last saw serious subsurface work more than 80 years ago.

The timing is not accidental. Domestic tungsten supply is an active U.S. national security concern. A Presidential Executive Order issued on 20 July 2026 placed critical mineral supply chains squarely in federal policy focus, and Eagle, a 36.5 km² claim block in White Pine County, Nevada, has sat untouched through decades of rising strategic demand for the metal it hosts.

Here is what the programme is designed to test, what two years of surface evidence told Spartan about where to drill, and what the assay results will need to show before Eagle advances from a promising exploration-stage asset into something with formal resource potential.

What Spartan is drilling at Eagle and what the campaign is designed to answer

Up to 3,000 metres of diamond core drilling will be put into three structurally distinct target types, with each target shaped and prioritised through two years of surface sampling, soil geochemistry, and geophysical survey work. Eagle sits approximately 120 km northeast of Ely, Nevada, covering 9,033 acres across 445 unpatented lode claims. Spartan holds 100% ownership.

The three target categories being tested are:

• Southeast tungsten skarn anomaly: a zone where geophysical signatures suggest mineralised rock formed by heat and fluid interaction between a granite intrusion and surrounding sediments
• Tungsten-silver-rubidium vein system: at least eight discrete veins mapped and sampled at surface, with high-grade rock chip results confirming metal presence across a broad footprint
• Induced polarisation (IP) geophysical targets: newly identified zones where subsurface electrical responses suggest mineralised rock at depth, though the source of those responses has not yet been confirmed by drilling

Testing three different geological models within a single campaign means Spartan is not betting the programme on one thesis. If the skarn disappoints but the veins show depth and continuity, the story changes shape rather than ending. If the IP targets prove to be mineralised rather than structural noise, Eagle’s prospective footprint could expand materially beyond what surface mapping alone defined.

Tungsten skarn drilling programmes in 2026 have faced a shared methodological challenge: distinguishing between grade continuity at surface and genuine mineralisation at economic widths and depths, a distinction that only core drilling can resolve and that the Mt Mulgine campaign in Western Australia is also working to answer.

Progressive assay results are expected as laboratory work is completed, with first results anticipated before the end of 2026.

The two years of surface work that earned this campaign its targets

The decision to drill did not arrive on ambition alone. Since acquiring Eagle, Spartan has conducted a multi-phase surface and near-surface exploration programme that generated the targeting data now guiding drill placement.

The vein system provided the most striking surface evidence. Spartan confirmed at least eight tungsten-silver veins across a footprint of approximately 2.7 km by 2.1 km (roughly 5.7 km²), with a cumulative mapped strike length of approximately 6.8 km. Several veins extended well beyond their historical boundaries.

Surface rock samples from those veins returned grades up to 5.18% WO₃ (tungsten trioxide, the standard grade metric for tungsten deposits), reported in July 2026.

Three distinct data streams fed the current drill targets:

• Vein mapping and sampling: confirmed high-grade tungsten at surface across a broad, multi-structure system with expanded strike lengths
• Tailings drilling (2025): returned weighted averages of 0.13% WO₃, 10.6 g/t silver, and 626 ppm rubidium, with multiple short intervals above 0.2% WO₃ (announced 18 December 2025)
• Soil geochemistry and IP geophysics: outlined kilometre-scale surface anomalies that aligned with mapped structures and defined the new subsurface targets

The tailings results carry a distinct investment thread. At 0.13% WO₃ weighted average with silver and rubidium credits, legacy tailings material represents a potential near-term, lower capital expenditure option that could support funding regardless of deeper drilling outcomes.

From past producer to modern drill target

Eagle encompasses the historic Tungstonia mine area, where production ran between 1915 and 1956 at reported grades of 0.6-1.12% WO₃. After operations ceased, the property saw no meaningful exploration for over eight decades.

Spartan’s surface programme reframed Eagle as a modern target rather than a depleted site. The confirmed vein footprint, the high-grade surface samples, and the newly identified IP anomalies all sit outside the boundaries of historical mine workings, which means the drills are testing ground that past operators never evaluated.

U.S. critical mineral policy, what the drills need to confirm, and what investors should watch

Tungsten is classified as a critical mineral by the U.S. government, with applications spanning defence manufacturing, industrial tooling, and advanced technology production. The country remains heavily reliant on foreign supply, a vulnerability that recent policy has moved to address directly.

Tungsten price dynamics in 2026 have reinforced the commercial case for domestic exploration, with supply constraints pushing prices to levels that improve the project economics of deposits that would have been marginal in prior cycles.

The USGS critical mineral classification for tungsten identifies the metal as essential to defence manufacturing, cutting tools, and advanced technology production, with U.S. import reliance remaining a persistent vulnerability in domestic supply chains.

Brett Marsh, President and CEO of Spartan Metals, noted that a Presidential Executive Order issued on 20 July “underscored the federal government’s position that securing domestic supply chains for critical minerals is a national priority.”

That policy backdrop means Eagle is not operating in a neutral environment. The Executive Order framework could affect permitting timelines, project financing access, and federal procurement interest in ways that purely exploration-stage projects without a critical mineral designation would not typically experience.

As assay results arrive through the remainder of 2026, three geological watchpoints will determine whether Eagle advances toward formal resource estimation:

1. Skarn target: Do drill intercepts confirm tungsten grade, continuity, and geometry at depth beneath the southeast anomaly?
2. Vein system: Do the veins that show high-grade tungsten at surface persist with meaningful width and grade below the oxidation zone?
3. IP anomalies: Do the geophysical targets reflect genuine mineralisation, or are the electrical responses generated by non-mineralised geological structures?

The third watchpoint carries the highest uncertainty. If the IP targets prove to be mineralised, Eagle’s footprint could expand well beyond the known vein system. If they prove to be geophysical artefacts, the programme’s upside is bounded by the skarn and vein results alone.

Spartan’s second U.S. tungsten asset, the Victorio Tungsten-Molybdenum Project in New Mexico, provides a parallel near-term data point. An updated Preliminary Economic Assessment (PEA), a study that estimates a project’s potential economics, is anticipated in Q4 2026. That means investors tracking Spartan through the remainder of the year receive two material catalysts rather than one.

Eagle’s place in the 2026 critical minerals story, and what comes after first results

Eagle is the 2026 operational centrepiece of a two-asset U.S. tungsten strategy. The maiden drill programme tests whether a property with confirmed high-grade surface expression, an 80-year exploration gap, and a supportive policy environment can deliver the subsurface continuity needed to advance toward formal resource status.

The broader tungsten investment thesis rests on a combination of inelastic industrial demand, concentrated global supply, and accelerating government procurement interest, factors that distinguish tungsten from cyclical base metals and make domestic project development commercially attractive beyond spot price moves alone.

All forward-looking statements remain contingent on results not yet in hand. Exploration-stage programmes carry inherent uncertainty, and surface grades, however strong, do not guarantee equivalent results at depth.

What positions Eagle for informed attention at this stage is the convergence of three factors: a disciplined, multi-phase surface programme that earned its targets through data rather than assumption; a U.S. critical mineral policy environment that elevates domestic tungsten supply from commercial interest to national security priority; and a programme design that tests multiple geological models simultaneously rather than relying on a single thesis.

With progressive Eagle assays and the Victorio PEA both expected before year-end, 2026 closes with two Spartan data points, not one, giving investors a fuller basis for evaluating where this story goes next.
