Seabridge Gold Begins Drilling at the 3 Aces Project

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

commenced at its wholly owned 3 Aces project in Canada’s Yukon to complete the testing of a

comprehensive exploration model. The program is scheduled to complete 7,500 meters of core

and reverse circulation drilling in the Central Core Area (CCA) of the 3 Ace s project. Initial

targets will focus on expanding mineralized zones on the Hearts and Spades targets.

Rudi Fronk, Seabridge Chairman and CEO, commented, “We are looking forward to execut ing

our first full program at 3 Aces. Our team has been refining our new model and checking its

concepts against field observations. They believe this model will provide the basis to integrate

past and current drill results into meaningful zones of mineralization. We expect this program

will help us prioritize mineralized zones and take us steps closer to delineating resources.”

Mr. Fronk noted that Seabridge Gold’s success as a Company has relied extensively upon

reserve and resource expansion at its 100%-owned KSM and Courageous Lake projects. “We are

proud of o ur explor ation rec ord and we are now gunning for our next round of exploration

successes at our 3 Aces and Iskut projects. The preparatory work has been done. At 3 Aces , we

are looking for the continuity that eluded previous operators and which is needed for resource

delineation. At Iskut, we are focusing on expansion of the Bronson deposit and the discovery of

new copper-gold porphyries hinted at in last year’s drilling.”

The 3 Aces program plans to test four target zones, Spades, Hearts, Hearts West, and Clubs. In

these zones, dilation at the contacts between thick phyllite sequences and coarse interbedded

sandstones and conglomerates along second-generation folding event (F2) have consistently

shown better gold values. Evaluations of the target areas will include:

• The gold mineralization in historical drill holes that has not been pursued down

plunge of the F2 folds.

• Untested synform -antiform pairs of the F 2 folds, identified within the extensive

gold-in-soil anomaly of the CCA.

• Interaction between structurally prepared rocks of the earlier F 1 folding and the

mineralizing F2 folds.

3 Aces was acquired by Seabridge in March 2020 as a district scale, orogenic gold project

consisting of 1,734 claims covering 357 km² (35,700 ha) . The property is in a readily accessible

part of southeastern Yukon , on the eastern margin of the Selwyn Basin, a thick package of

sedimentary rocks extending across the Yukon and host to several enormous base metal

deposits (Howard’s Pass District). Hosted in Hyland Group rocks, interbedded clastics and

carbonate sediment s are exposed near a regional tectonic boundary. A p olyphase fold and

fault system overprint s the stratigraphy, creating ideal traps for gold -bearing fluids expressed

as quartz veins. We believe the 3 Aces target is 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.

Seabridge holds a 100% interest in several North American gold projec ts. Seabridg e's asset s

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 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
