Vancouver, British Columbia--(Newsfile Corp. - June 30, 2026) - Spartan Metals Corp. (TSXV: W) (OTCQB: SPRMF) (FSE: J03) ("Spartan" or the "Company") validates historic drilling data which supports the upcoming Preliminary Economic Assessment ("PEA") announced May 5, 2026 at its Victorio Tungsten-Molybdenum Project, New Mexico (Figure 1).

Historic Drilling Highlights:

• 34 holes exceed 100 feet (~30.5 meters) of continuous Tungsten-Molybdenum mineralization
  • Additional multiple stacked zones of mineralization over 50 feet (~15.2 meters) occur throughout deposit
• 26 holes not included in 2008 historic economic analysis, including 12 holes that were not included in the 2012 historic mineral resource estimate, suggest significant upside potential once these holes are considered in the current PEA update
• Tungsten and molybdenum combined establish molybdenum equivalent (MoEq) grades at Victorio 0.09% WO3 and 0.09%¹ Mo (0.19% MoEq) compare favorably to Freeport-McMoRan's Henderson Mine resource grade of 0.14% Mo²
• PEA on target for early Q4 2026 release

Brett Marsh, Spartan's President and CEO, stated: "The validation of these historic drill results marks an exciting milestone in our ongoing technical evaluation of the Victorio Project and further reinforces our conviction that acquiring this asset was a transformational opportunity for Spartan Metals. The identification of 34 drill holes with more than 100 feet of continuous tungsten-molybdenum mineralization demonstrates the impressive scale and continuity of the mineralized system. Equally encouraging is the fact that many of these large, mineralized intervals were not incorporated into previous resource estimates or historical economic evaluations, providing additional technical information as we advance the updated Preliminary Economic Assessment for Victorio.

"Our ongoing data validation program continues to uncover the breadth of historical drilling completed at Victorio and is providing new insights into the size and characteristics of the mineralized system. The combination of extensive continuous mineralization, broad mineralized widths, and apparent bulk-tonnage characteristics highlights why we believe Victorio compares favourably, from a geological perspective, with large underground molybdenum systems such as Freeport-McMoRan's Henderson mine, while also benefiting from a significant tungsten component that distinguishes the Victorio Project. Although Victorio remains at a much earlier stage of technical evaluation, these historical results continue to reinforce our confidence in the project's strategic importance within the U.S. critical minerals sector.

"As we move toward the completion of the updated PEA, our team remains focused on systematically validating the historical database and integrating this information into our geological and engineering studies where appropriate. Every phase of this work continues to strengthen our understanding of Victorio and further demonstrates why we believe the project has the attributes of a significant U.S. tungsten-molybdenum development opportunity."

Spartan's current PEA is on target for early Q4 2026 release. The drilling database validation is the first step to ensuring accurate input information into the Mineral Resource Estimate that is the foundation of the PEA. The database contains 147 core holes totaling 253,955.5 feet (77,405.6 m). Significant intervals from selected holes are shown in Table 1 and a more complete list is located here. Figure 2 shows a plan view of the drill holes within the Victorio Project. Note several holes within the deposit footprint that have not been included in previous economic analyses or Mineral Resource Estimates.

Victorio exhibits several geological and mining characteristics that are comparable to large-scale underground molybdenum systems such as Freeport-McMoRan's Henderson Mine in Colorado, one of North America's premier bulk underground molybdenum operations. Historical drilling at Victorio has outlined broad, laterally continuous intervals of tungsten-molybdenum mineralization, with numerous drill holes reporting intervals of more than 100 feet (30.5 m) of continuous mineralization and demonstrating vertical continuity over several hundred metres. Similar to Henderson, mineralization occurs as a widespread stockwork system capable of supporting evaluation of bulk underground mining methods such as those being evaluated in Spartan's PEA.

Although Victorio is at an earlier stage of technical evaluation and currently reports average molybdenum grades of approximately 0.09% Mo and 0.09% WO₃ (0.19% MoEq) in the historical resource², the addition of tungsten-and potentially fluorspar-results in metal-equivalent grades that compare favorably with large, low-grade bulk underground systems. Importantly, historical drilling indicates that mineralization begins at relatively shallow depths compared with Henderson, where the deposit is located more than 1,000 metres below surface¹, while also exhibiting broad mineralized widths and encouraging vertical continuity that support continued evaluation of underground mining scenarios. As the Company advances its updated Preliminary Economic Assessment, it believes objective comparisons to established bulk underground operations such as Henderson provide a useful framework for assessing mining method, scale and continuity, while recognizing that Victorio remains an independent project with its own geological characteristics and no assurance that similar mining or economic outcomes will be achieved.

Qualified Person Statement
The technical information contained in this news release has been prepared under the supervision of, and approved by Brett R. Marsh, CPG. Mr. Marsh is President and CEO of Spartan Metals Corp. and a "qualified person" as defined under National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

The Company cautions that production, tonnage, grade and recovery information relating to the historic Victorio Project mineral resources and economic assessments are considered "historical" in nature and are not supported by a current NI 43-101 compliant technical report.

The historical information referenced herein is derived from two NI 43-101 Technical Reports completed for previous operators, which the Company believes to be reliable, but has not independently verified. There has been no systematic exploration and/or verification work completed by Spartan to date to confirm the historical mining, grade or metallurgical information reported for these past operations.

The references in this news release to historical production, resources, and economic assessments are provided for context only and should not be interpreted as indicative of the mineralization that may be present on Spartan's current claims, nor as evidence of the economic viability of the Victorio Project. There is no assurance that Spartan's exploration programs will confirm the presence of economically mineable mineralization, or that any future resource estimates will reflect similar grades, tonnages or recoveries to those historically reported.

The historical estimate is considered relevant as it provides an indication of the potential mineralization on the property and supports the Company's decision to further explore the project. The Company considers the historical estimate to be reliable as it is based on internal due diligence and estimate verification from an independent contractor that, in management's view, were carried out in a manner consistent with industry practice. However, a qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and the Company is not treating the historical estimate as current mineral resources or mineral reserves.

The historical estimate uses the categories Measured, Indicated and Inferred which are consistent with current standards however, a qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves.

Spartan is not aware of any Mineral Resource Estimates subsequent to the historic 2012 estimate.

To verify the historical estimate as a current mineral resource, the Company's planned work program includes: confirmatory twinning of select historical drill holes, additional infill and step out drilling, re sampling of available core, verification of historical assay data, application of modern QA/QC protocols, updated geological modeling, and estimation using current CIM Definition Standards and NI 43 101 compliant procedures which will be included in the upcoming PEA. Until this work is completed and a qualified person has prepared a current mineral resource estimate, the historical estimate should not be relied upon as a current mineral resource or mineral reserve.
