Seabridge Gold 2024 Drill Program to Pursue

Confirmed Exploration Model at 3 Aces Project

Drilling aims to move towards resource estimation

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

well underway at the wholly-owned 3 Aces proj ect in Canada’s Yukon to expand upon the

comprehensive exploration model confirmed from last season’s drill program . This year’s

program is a multi -pronged effort to apply the exploration model to new targets within the

Central Core, evaluate the size and potential of existing zones, and assess the exploration

model at regional targets across the larger 3 Aces property.

The fully funded program plans to complete additional geophysical surveys and about 8,000

meters of core and reverse circulation drilling in the Central Core Area and outlaying targets on

the 357 km2 3 Aces property at a budgeted cost of $6.0M.

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

team has confirmed several key parameters that are critical to localizing gold concentrations in

the Central Core Area. Findings from last season’s program give us confidence in our ability to

expand mineralized zones utilizing our robust exploration model . We are excited to apply this

understanding across more of the 3 Aces land package. We view this year’s work as pivotal for

moving the project towards resource delineation.”

The 3 Aces exploration model predicts continuity of mineralization, including high-grade gold,

localized along the limbs of second -order folds (F 2). Mineralized zones are best expressed at

the contacts between thick phyllite sequences and coarse interbedded sandstones and

conglomerates. Shearing along fold limbs at th ese rheologic contact s result in brittle

fracturing and Au bearing quartz veining preferentially hosted in coarser clastic units.

Evidence indicates that this structural architecture is regional in nature and multiple F 2

synforms and antiforms have been identified across the property. Substantiating the presence

of these controls on gold mineralization outside of the Central Core Area would provide

Seabridge with confirmation of a district scale project.

Additional exploration efforts planned for this season will evaluate the limit of several targets

within the Central Core Area. This work is intended to deliver indications of size potential on

several known high-grade zones and provide additional refinements on the controls for gold.

Last year ’s exploration work also revealed the potential for additional target concepts not

previously recognized. S urface mapping and geophysical surveys are planned to assist in

refining these early-stage concepts.

Seabridge will also resume its previously initiated reclamation activities at the site,

concentrating on exploration roads. Environmental monitoring activities focusing on wildlife

management, water sampling and understanding environmental baseline conditions will

continue in support of exploration activities.

3 Aces was acquired by Seabridge in March

2020 consisting of 1,734 claims covering 357

km² (35,700 ha) located in a readily accessible

part of southeastern Yukon . Historical work

identified a broad area of gold -in-soil

extending more than 20 kilometers and past

drilling encountered extensive gold. We

believe t he characteristics of the 3 Aces

project are indicative of a district scale,

orogenic gold project consistent with other

deposits in the vicinity and around the world.

Exploration activities on the 3 Aces 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

Seabridge holds a 100% interest in several

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 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
