Seabridge Gold’s 2023 Iskut Drill Program Ramps Up

Focused on Making New Copper-Gold Porphyry Discoveries

Toronto, Canada...Seabridge Gold (TSX:SEA) (NYSE:SA) reports today 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.

Seabridge Chairman and CEO Rudi Fronk commented: “ We are excited to get our program

started early in the field season after last years success at Iskut. At Snip North, we have extensive

evidence of copper-gold mineralization in historical drilling and deep penetrating geophysical

surveys. As the season matures and snow melts , we’ll move upslope, following a pronounced

regional structural tend, to continue work below the Bronso n Slope target. Our team is

enthusiastic that both these targets are new copper-gold rich porphyry systems. In addition, we

think there is significant potential to expand the existing Bronson Slope mineral resource.”

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 our 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. Deeper drilling 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.

Seabridge holds a 100% interest in s everal North American gold projects. Seabridge's assets

include the KSM and Iskut projects located in Northwest British Columbia, Canada’s “Golden

Triangle”, the Courageous Lake project located in Canada's Northwest Territories, the

Snowstorm project in th e Getchell Gold Belt of Northern Nevada and the 3 Aces project set in

the Yukon Territory. For a full breakdown of Seabridge's Mineral Reserves and Mineral Resources
