Seabridge Gold reported that drilling has begun at its 100% owned Iskut property in Northwestern B. C.'s Golden Triangle. Initial work is on the Snip North target and will then expand to the Bronson Slope target in coming weeks. The first of three helicopter-portable core drills has been mobilized to site and two other drills will arrive in coming weeks.

The 2023 Iskut program plans to complete 12 to 15 drill holes exceeding 12,000 meters. Regional geophysical surveys and surface geology continue to confirm a district scale structural feature that connects the Quartz Rise, Bronson Slope and Snip North targets. All the recognized mineral occurrences at Iskut are interpreted as high-level expressions of Cu-Au porphyry systems aligned along this regional structural trend.

The trend has similar characteristics to the one that hosts a cluster of porphyry systems Seabridge has defined at nearby KSM project. An MT survey that began last season is being expanded at Snip North. This survey is investigating extensive sericite-pyrite alteration and Cu-Au geochemical anomalies in sedimentary rocks identified by 32 shallow diamond core holes previous operators drilled.

De De Degegegeology is planned to identify the source of this alteration and related copper-gold concentrations. The initial objective is to complete 3,500 meters of drilling in three to four holes at Snip North, which could then be expanded depending on results. The main part of the 2023 program will continue the drilling below the Bronson Slope resource which started last year and discovered a large, steeply plunging quartz-magnetite breccia pipe with clear indications of being sourced from hydrothermal eruptions out of an intrusion.

The copper and gold concentrations within and on the margins of this breccia pipe are evidence the source intrusion could host a significant mineral system. Results from drilling in 2022 also identified copper and gold grades in sedimentary rocks outside of the Bronson Slope mineral resource. Resource expansion potential will be evaluated from results in the shallow parts of holes targeting the deeper breccia pipe and its intrusive source.

Exploration activities by Seabridge at the Iskut Project are being conducted under the supervision of William E. Threlkeld, Registered Professional Geologist, Senior Vice President of the Company and a Qualified Person as defined by National Instrument 43-101. Mr. Threlkeld has reviewed and approved this news release. An ongoing and rigorous quality control/quality assurance protocol is employed in all Seabridge exploration campaigns.

This program includes blank, duplicate and reference standards. Cross-check analyses are conducted at a second external laboratory on at least 10% of the drill samples.
