Core Silver Reviews Widespread Gold Results

Executive Summary

• Core Silver released extensive gold‑bearing assay results from multiple targets across its 100% owned Silver Lime Polymetallic Project, highlighting several high‑grade Au–Ag intersections.
• The North Gold, Falcon, Jackie, Pete’s, Amp & Pike Valley, and Grizzly targets all returned notable Au grades (up to 19.5 g/t) and accompanying Ag values, confirming a widespread precious‑metal system extending ~9 km laterally.
• Ongoing drilling at the Jackie target continues; assay results are pending, indicating further potential upside.

Key Details

• North Gold Target: Up to 1.81 g/t Au and 111 g/t Ag over a 120 m‑wide zone; majority of samples >0.25 g/t Au and >10 g/t Ag.
• Falcon Target: Notable intercepts include 19.5 g/t Au & 33 g/t Ag (sample D935063); 1.82 g/t Au with 65 g/t Ag & 9.92% Cu; 3.67 g/t Au with 2,641 g/t Ag & >4% Pb+Zn.
• Jackie Target: Hole SLM22‑004 – 2 m @ 5.42 g/t Au & 5.6 g/t Ag; additional 8 m @ 0.69 g/t Au & 6.5 g/t Ag at 335 m depth.
• Pete’s Target: Hole SLM23‑026 – multiple 2‑m zones grading 0.24–1 g/t Au (45 m depth); Hole SLM23‑029 – 1.64 m @ 3.46 g/t Au & 64 g/t Ag at 10.36 m depth.
• Amp & Pike Valley Targets: Historic samples up to 0.75 g/t Au, 260 g/t Ag, 6.5% Pb, 3.8% Zn (F421207); 2.98 g/t Au, 497 g/t Ag, 0.44% Cu, 3.0% Pb (152058).
• Grizzly Target: 2022 drill hole SLM22‑011 – 5.64 m @ 254 g/t Ag, 5.1% Pb, 4.8% Zn, 0.11% Cu, 0.12 g/t Au; sub‑intervals include 3.15 m @ 424 g/t Ag and 1.16 m @ 1,145 g/t Ag with associated base‑metal grades. Recent surface sampling returned up to 1.32 g/t Au & 545 g/t Ag.
• Assay Methodology: Samples processed by Bureau Veritas Labs using 4‑acid digestion (ICP‑MS) and fire assay (Pb collection) per NI 43‑101 standards; historic drill results presented as uncut weighted averages.
• Forward‑Looking Statements: Company plans to continue drilling at Silver Lime following the Laverdière Copper Project program; acknowledges execution risks and funding uncertainties.
