Updated resource estimate awaited for Bronson Slope deposit

Deeper drilling on Bronson pipe confirms porphyry target

Toronto, Ontario--(Newsfile Corp. - December 20, 2023) - Seabridge Gold (TSX: SEA) (NYSE: SA) reports today on the Bronson Slope drilling program at its 100% owned Iskut property in Northwestern B.C.'s Golden Triangle. Results are confirming an extensive area of magmatic-hydrothermal alteration sourced from the high fluid flux of a porphyry mineral system that generated the unusually large explosive breccia pipe discovered in 2022 and the intermediate epithermal occurrence that expands the known Bronson Slope copper-gold deposit.

The 2023 Bronson Slope program was designed to evaluate simultaneously the potential to expand the Bronson Slope resource and test at depth for its source. Results identified broad zones of sericite-pyrite-carbonate alteration associated with continuous low gold grades. This is our second news release on Iskut 2023 exploration results; last week we released a report on our first drill program on the Snip North target (see here).

Seabridge Chairman and CEO Rudi Fronk commented: "One of the concepts that led us to acquire the Iskut Project was the expectation that a larger epithermal mineral deposit could potentially be preserved at Bronson Slope. This expectation has been confirmed but as we have learned more about this occurrence, we have become more convinced and excited about the potential to find its source porphyry. Next year's program will aim to integrate the upside at Bronson Slope with our hypothesis of a regional structurally-controlled porphyry district encompassing the entire Iskut project."

Drilling adjacent to, and mainly east of, the Quartz-Magnetite Breccia Pipe (QMBX), discovered in 2022, provided information on the potential to expand the existing Bronson Resource. Across this part of the project area, we encountered a clear upper zone hosted by a Triassic sedimentary section characterized by hornfels, bedded arkose and mudstone. Superimposed on this upper zone of thermally metamorphosed rock is a hydrothermal alteration including pyrrhotite-biotite-sericite and abundant carbonate tension gashes. Localized areas in this part of the system contain abundant sphalerite. This alteration style gives way to a lower zone of intensive sericite-pyrite-carbonate where gold grades are extensive.
