Seabridge drills 729 m of 0.48 g/t Au, 0.16% Cu at Snip

Executive Summary

• Seabridge Gold reported intersecting significant copper‑gold porphyry mineralization in the first three holes of its 12,000 m summer drill program at the Snip North target.
• All three holes (SN‑25‑25, SN‑25‑26, SN‑25‑27) extended the known mineralized footprint and confirmed wide zones of potassic alteration with copper‑gold grades.
• The company aims to achieve a maiden resource estimate for Snit North early next year, targeting a deposit measuring roughly 1,700 × 600 × 600 m.

Key Details

• Program Scope: 12,000 m drill program designed to expand zones of intense potassic alteration discovered in 2024.
• Hole SN‑25‑25:
• Depth interval 62–790 m intersected continuous quartz‑carbonate‑sulphide and quartz‑sulphide veins with pyrite and chalcopyrite mineralization.
• Shows up‑dip and southward extension of 2024 mineralization; notable potassic and phyllic alteration zonation.
• Hole SN‑25‑26:
• Extends mineralization along strike to the north, intersecting potassic alteration throughout the hole.
• Encountered quartz‑sulphide‑biotite and quartz‑carbonate‑sulphide veins; complete magnetite‑pyrite‑chalcopyrite replacement in carbonate‑rich units.
• Hole SN‑25‑27:
• Step‑out east to test strike extension of intense potassic alteration.
• Intersected a replacement‑style quartz‑magnetite‑chalcopyrite breccia and discrete carbonate‑sulphide‑magnetite veins from surface to ~280 m, with associated chalcopyrite and biotite.
• Assay Protocol: Samples sent to ALS Global (ISO‑accredited) in Langley, B.C.; quality control includes blind certified standards, blanks, and duplicates per industry practice.
• Qualified Person Review: Release reviewed and approved by William Threlkeld, P.Geo., Senior Vice‑President, under NI 43‑101.

Notable Quotes

“We are very excited by the early results from this year's program. Our drilling is designed to achieve a density of pierce points needed for a maiden resource from a mineralized zone that so far measures approximately 1,700 by 600 by 600 metres, with the aim of announcing a resource estimation for Snip North early next year.” – Rudi Fronk, Chairman & CEO

Materiality Assessment: Material – Positive (significant new drilling results indicating a large copper‑gold porphyry system and supporting near‑term resource development).
