Seabridge Gold Completes Initial Drill Program at 3 Aces Project

Target parameters established for major drill program in 2023

Toronto, Canada... Seabridge Gold (TSX: SEA, NYSE:SA) announced today that drilling has been

completed and assay results received from its limited 2022 drill program . The program

commenced in mid -September after receiving a Class 4 Quartz Exploration Permit from the

Yukon Government Department of Energy, Mines, and Resources for its 100% owned 3 Aces

project. As one of the permit conditions requires that drilling cease each year at the end of

October, only four holes were drilled.

The limited program was designed to begin testing our 3-dimensional model around the Hearts

zone and determine which structural settings would enable us to begin establishing an initial

resource. One drill hole was used to confirm that gold- bearing structures are hosted within

secondary aniticlinal folds and thrust faults as predicted by our model. The assays from this hole

were highly rewarding, as expected. The three additional holes were used to test for controls on

down dip extensions to the high grade. These holes determined that the gold-bearing structures

are pronouced as they continue down plunge but only carry coherent high grades where they

exhibit flexures that enhance permeability.

Additionally, required upgrades were completed at the exploration camp, environmental

monitoring programs were initiated, and ongoing rehabilitation and reclamation work was

begun. These efforts were supported by First Nation contractors from Watson Lake and Ross

River under difficult weather conditions and time constraints. This work has prepared the project

for a much larger 2023 program.

3 Aces was acquired by Seabridge in March 2020 , consisting of 1,734 claims covering 357 km²

(35,700 ha), as a district scale, orogenic -gold project located in a readily accessible part of

southeastern Yukon. Target concepts for this project are consistent with some of the biggest

and richest gold deposits in the world, including the California Mother Lode Belt, Juneau Gold

Belt, Muruntau in Uzbekistan, and Obuasi in Ghana. Although previous work identified a broad

area of gold -in-soil occurrences extending more than 20 kilometers (12.4 miles) along strike ,

historical drilling focused in a 13 -kilometer square region known as the Central Core Area. This

drilling found good widths of high-grade gold but did not establish the continuity required for a

resource estimate.

Commenting on this year’s program, Rudi Fronk, Seabridge Chairman and CEO, noted: “We were

hoping to accomplish more in 2022, but the late start and challeging conditions slowed progress.

Initial results indicate that our new model , with further modifications, should resolve many of

the continuity questions at 3 Aces. Although only limited data acquision was accomplished in

this program we are confident we have moved closer to our goal of defining a large resource in

coming seasons.”

Hearts Main Zone

Two drill holes were completed at the Hearts Main Zone to evaluate the character and controls

of gold hosted in this target. The initial hole, 3A22-355, pierced the Hearts Main Zone structure

on the limb of a secondary anticline intersecting a broad zone of gold mineralization with a high-

grade core. Results from that hole are consistent with previous intersections in the Hearts Main

Zone, near the apex of a secondary fold.

A second hole, 3A22-356, was drilled down dip of 355 to confirm the continuity of the structure.

The structural corridor was found to continue down dip where it was expected but as multiple

sheared intervals or splays. Additional drilling is required to evaluate the changing geometry

and character of high-grade gold mineralization down dip. Preliminary CSAMT geophysical data

suggests the gold-bearing structural corridor is folded down dip. We believe these flexures are

likely to provide the fracturing required to accommodate and trap the gold-bearing fluids. The

CSAMT survey will be expanded in 2023 to identify these variations in the structural corridor and

improve targeting.

Hearts West Zone

The Hearts West Zone is directly west of the Hearts Main Zone across a post-mineral normal fault.

This separate structural block hosts a broad gold and arsenic in soil anomaly and extensive

surface exposures. Surface mapping confirms the Hearts West Zone hosts the same g eology

and deformation events as the Hearts Main Zone. The Hearts West Zone is deformed by

secondary anticlines and synclines with recognized thrust faults on the limbs of the

folds…precisely the characteristics predicted to be productive by our model. Little previous

drilling has been conducted on this zone.

Two holes were drilled into this target zone and both intersected low -grade mineralization in

host rocks similar to those at the Hearts Main Zone. The drill results are inconsistent with highly

anomalous soil geochemistry which appear to identify grade -enhancing flexures . Additional

drilling and surface work within this separate structural block is required to locate favourable

structural intersections along strike.

All intervals reported were drilled perpendicular to the surface expression of the targeted

structure, however additional work is required to confirm that intervals are true thickness of a

mineralized feature. 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. At 3 Aces

this program includes blank, reference standards and metallic screen fire assays. Cross -check

analyses are conducted at a second external laboratory on at least 10% of the drill samples.

Seabridge holds a 100% interest in several North American gold projects. Seabridge's principal

asset, the KSM project, and its Iskut project are located in Northwest British Columbia, Canada’s

“Golden Triangle”, the Courageous Lake project is in Canada's Northwest Territories, the

Snowstorm project in the 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
