Churchill intersects 19.23% Sb over 1.40 m at Frost Cove North; 0.78% Cu, 61.2 g/t Ag over 6.22 m at Black Raven

TORONTO, ON / ACCESS Newswire / August 28, 2026 / Churchill Resources Inc. ("Churchill" or the "Company") (TSXV:CRI.V) is pleased to report final assay results from its Spring 2026 program of core drilling and trenching at the Black Raven Project. The work was focused on both Pomley Cove Pond ("PC Pond") where the Company's recent discovery of a potentially extensive polymetallic vein swarm associated with rhyolitic volcanic rocks has been significantly expanded, and a second round of delineation drilling of the Frost Cove North antimony-gold prospect.

The Spring program included the drilling of 23 drillholes, with a cumulative depth of 4,267m (Table 5), along with extensive trenching, channel, and soil sampling. Fourteen holes, totalling 2,979m depth, were dedicated to expanding the PC Pond prospect (Fig. 1, Tables 1-3) , and the remaining nine holes (cumulative of 1288m) to delineation work at Frost Cove North (Fig. 2, Table 4); all results reported here. Most holes were surveyed by televiewer to assist with Leapfrog modelling of the PC Pond complex and refining the Frost Cove North geological model.

At PC Pond, the 2026 drilling both expanded the Au-Ag-Mo vein swarm and discovered a broad succession of associated felsic extrusive rocks first intersected in hole PC25-02, within the down-dropped portion of a regional graben structure, that appears to be at, or near, the locus of the Black Raven mineralization and quartz-feldspar porphyry dykes. A delineation drilling program for the Fall on the Peninsula Vein Swarm ("PVS") is being planned, to target the strike extents of, and drill the first deep holes into, the mineralized structure.

At Frost Cove North the highlight was drillhole FC26-34, targeted on a gap in our 2025
