Spartan Metals (SPRMF) announced on September 3, 2026, that it has joined the Defense Industrial Base Consortium (DIBC) as it advances its U.S. tungsten and critical minerals portfolio.
The DIBC is a collaborative network of government, industry, academic and non-traditional participants focused on strengthening the U.S. defense industrial base. Spartan plans to use its membership to monitor consortium opportunities, explore collaboration pathways, and engage stakeholders involved in strategic and critical materials supply chains.
The company explicitly cautions that DIBC membership alone does not represent any grant, funding award, government contract, project approval, procurement decision, or endorsement by the DIBC or the U.S. Government, and there is no assurance any proposals, if submitted, will be selected or lead to agreements.
Spartan focuses on critical minerals projects in stable mining jurisdictions in the Western United States, targeting a portfolio that includes tungsten, rubidium, antimony, bismuth, and arsenic. The technical information in the release was reviewed and approved by President and CEO Brett R. Marsh, a qualified person under NI 43-101.
Spartan Metals (OTCQB: SPRMF) has begun its maiden diamond core drilling program at the 100%-owned Eagle Tungsten-Silver-Rubidium Project in Nevada. The 2026 program plans up to 3,000 m of drilling across three priority target areas, including the SE Tungsten Anomaly, a tungsten-silver-rubidium vein system, and new IP geophysics-defined targets.
According to Spartan Metals, the fully funded program aims to test depth and continuity of vein mineralization, assess tungsten skarn potential, and refine the broader mineral system. Initial assay results will be released as they become available. Eagle complements Spartan’s Victorio Tungsten-Molybdenum Project, which has a PEA update expected in Q4 2026.
Spartan Metals (OTCQB: SPRMF) reported new assay results and mapping that expand the mineralized footprint at the past-producing Tungstonia mine, part of its 100%-owned Eagle Project in Nevada, to about 2.7 km by 2.1 km (~5.7 km2), a more than 13-fold increase since July 2025.
The company has now confirmed 8 tungsten-silver veins with a cumulative exposed surface strike length of roughly 6.8 km. Rock chip and core samples returned tungsten grades up to 5.18% WO3 and silver up to 308 g/t, though Spartan notes these are individual results and not representative of average grade or economic viability. About 50% of the Tungstonia claims remain unexplored, and Spartan plans ground geophysics and approximately 3,000 m of diamond core drilling starting in early to mid-August 2026.
Ridgeline Minerals (OTCQB: RDGMF) reported that on July 13, 2026 it disposed of 600,000 common shares of Spartan Metals at $0.48 per share, for gross proceeds of $288,000 (the “Disposition”).
Before the Disposition, Ridgeline beneficially owned or controlled 5,380,466 Spartan shares, or about 10.77% of Spartan on an undiluted basis. After the sale, it holds 5,230,466 shares, or approximately 8.84%. This reduction drops Ridgeline below the 10% early warning reporting threshold under Canadian securities laws, so it is no longer subject to ongoing early warning reporting for this holding unless its interest rises back to 10% or more. Ridgeline says it holds the shares for investment purposes and may adjust its position depending on market and company-specific factors. An early warning report has been filed on SEDAR+.
Spartan Metals (OTCQB: SPRMF, TSXV: W) reported new assays from the past producing Rees Tungsten Mine within its 100%-owned Eagle Project in Nevada. Underground rock-chip samples returned 6.76% and 3.75% WO3, while historic USBM work reported up to 8.48% WO3.
Historic records indicate about 1,306 stu (1,185 mtu) shipped at an average grade of 3.51% WO3 in 1954–1955. According to Spartan, repeated confirmation of >1% WO3 at Rees, Yellow Jacket and Tungstonia supports its view of a potentially significant, district-scale tungsten system. The 2026 program includes surface sampling, geophysics and about 3,000 m of diamond drilling starting early to mid-August.
Spartan Metals (OTCQB: SPRMF) reported validation of historic drilling at its Victorio tungsten-molybdenum project in New Mexico, supporting an updated Preliminary Economic Assessment targeted for early Q4 2026.
Highlights include 34 holes with >100 ft mineralization and a 537 ft (163.7 m) interval grading 0.31% MoEq or 0.23% WO3Eq.
Spartan Metals (OTCQB: SPRMF) reported silver-antimony-copper assays from the past producing Antelope Mine at its 100% owned Eagle Project in Nevada.
Backpack core drilling returned up to 688 g/t Ag over 0.3 m, while surface samples reached 1,927 g/t Ag, 0.67% Sb, and 1.83% Cu across a ~1.3 km by 0.6 km area.
Spartan Metals (OTCQB: SPRMF, TSXV: W) confirmed two tungsten skarn zones at its 100%-owned Eagle Tungsten-Silver-Rubidium Project in Nevada, including the past-producing Yellow Jacket Mine and the SE Tungsten Anomaly.
Rock chips returned up to 1.87% WO3 and 3.3% Zn, with beryllium to 1,320 ppm. Backpack core drilling intersected 0.3 m at 0.21% WO3 and 0.33% Zn and revealed molybdenum to 0.08%, rubidium to 2,122 ppm, and silver to 3.1 g/t over a mineralized trend of roughly 2 km. Ongoing work includes ground geophysics and about 3,000 m of diamond core drilling planned for early to mid-August 2026.
