About this update from Sparton Resources Inc.

Sparton Advances Pense Critical Metals Project TORONTO, ON / ACCESS Newswire / April 15, 2026 / Sparton Resources Inc. (TSXV-SRI) ("Sparton" or the "Company") is pleased to announce continued progress at its Pense Critical Metals Project, where the Company is advancing a district-scale exploration model targeting polymetallic sulphide mineralization associated with mafic-ultramafic systems. The model is based upon on deposits found in Finland such as Outokumpu, Kevitsa and Talvivaara.The Company has added to its large land holdings, which straddle the Ontario/Quebec border, with the addition of 40 more claims. The total land position now comprises 185 claims, covering approximately 9,000 hectares. Several claim applications in restricted areas are awaiting approval.A Target EM airborne geophysical survey was completed by Expert Geophysics of Aurora, Ontario, on portions of the Pense claim group not covered by earlier work. Several new conductive anomalies were identified, bringing the total count of anomalies to 16 of which 14 remain untested.Systematic testing of these anomalies is being carried out, with an initial two-hole test of Anomaly A on the Quebec side of the property. This work tested a strong electromagnetic (EM) anomaly identified by airborne and ground geophysical surveys conducted earlier by Sparton. The holes were 100 meters apart and were drilled to depths of 138 meters and 217 meters, respectively. The conductive sulphide zones were intersected in both holes at the contact between mafic-ultramafic volcanic rocks and black sedimentary units. No graphite was seen associated with the mineralization.Results HighlightsBoth holes intersected zones of disseminated, stringer, and locally semi-massive and massive sulphides including chalcopyrite, pyrrhotite, pyrite and lesser sphalerite and pentlandite. A 5-7-meter-wide zone occurs near the top of each hole containing 0.03%-0.16% chromium (Cr) and represents the first identification of chromium enrichment by the Company in this area.Highlights Assay ResultsAll sample lengths were nominally 1.5 meters and core angles indicated these lengths were close to true widths for the mineralization.Highlights of assay results include:Chromium: 0.03%-0.16%Copper: 0.04% to 0.40% CuNickel: 0.06% to 0.23% NiZinc: 0.05% to 0.80% ZnCobalt (anomalous samples): 0.016% to 0.019% Co, in Holes PM -01 and PM-02Notable ...
