Seabridge Gold’s Iskut 2023 Drill Program to Focus on Copper-Gold

Porphyry Discoveries and Resource Expansion

Last year SBS-22-05 intersected 174 meters of 0.86 gpT gold and 0.34% copper

in newly discovered Bronson Pipe

Toronto, Canada...Seabridge Gold (TSX:SEA) (NYSE:SA) reports today that planning is well advanced

for an extensive 2023 drill program at its 100% owned Iskut property in Northwestern B. C.’s Golden

Triangle. The work program is designed to test for deeper copper -gold porphyry systems and to

expand the Bronson Slope mineral resource. Three helicopter-portable core drills have been reserved

for this program that anticipates completion of 12 to 15 drill holes exceeding 12,000 meters of core.

Seabridge Chairman and CEO Rudi Fronk commented: “Last year we discovered a major quartz -

magnetite breccia pipe beneath the Bronson Slope copper -gold deposit. The pipe sits within a

district-scale structural trend that localizes all of Iskut’s porphyry-style targets. The well-mineralized

Bronson pipe is persuasive evidence of a large copper-gold porphyry source below last year’s drilling.

The structural trend hosting this pipe has two more similar porphyry targets meriting aggressive drill

testing. As a byproduct of this effort, we expect to expand the 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 observed mineral

systems at Iskut are interpreted as high -level expressions of Cu -Au porphyry features along this

regional trend. Snip North is being investigated with an MT survey and deeper drilling this year over

an area where 32 shallow diamond core holes drilled by previous o perators encountered pervasive

sericite-pyrite alteration and Cu-Au geochemical anomalies in sedimentary rocks.

At Bronson, drilling will continue below the Bronson Slope resource following a steeply plunging

quartz-magnetite breccia pipe with clear indications it is sourced from hydrothermal eruptions out

of an intrusion. The copper and gold concentrations within and on the margins of this pipe are

evidence the source intrusion could host a significant mineral system. At Quartz Rise ongoing work

has refined drill targets for the intrusive source of an extensive lithocap discovered at this target.

Results from drilling in 2022 identified copper and gold grades in sedimentary rocks outside of the

187Mt Bronson mineral r esource. Resource expansion potential may extend as far as 1.2 kilometers

southeast along strike , connecting to historical drilling that encountered numerous high -grade

intersections. Magnetic surveys in that area indicate a separate intrusive feature is present under this

area which may be another porphyry source. Drill testing the Bronson Slope breccia pipe will require

drilling outside the limits of the resource and these results wi ll be incorporated into the resource

estimate.

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 blan k, 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 several North American gold projects. Seabridge's principal assets,

the KSM project, and its Iskut project are located in 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 by category please visit the Company's website

Neither the Toronto Stock Exchange, New York Stock Exchange, nor their Regulation Services Providers accepts

responsibility for the adequacy or accuracy of this release.

All reserve and resource estimates reported by the Corporation were estimated in accordance with the Canadian National

Instrument 43-101 and the Canadian Institute of Mining, Me tallurgy and Petroleum (“CIM”) Definition Standards. The U.S.

Securities and Exchange Commission (“SEC”) now recognizes estimates of “measured mineral resources,” “indicated mineral

resources” and “inferred mineral resources” and uses new definitions of “p roven mineral reserves” and “probable mineral

reserves” that are substantially similar to the corresponding CIM Definition Standards. However, the CIM Definition Standards

differ from the requirements applicable to US domestic issuers. US investors are cautioned not to assume that any “measured

mineral resources,” “indicated mineral resources,” or “inferred mineral resources” that the Issuer reports are or will be

economically or legally mineable. Further, “inferred mineral resources” are that part of a mineral resource for which quantity

and grade are estimated on the basis of limited geologic evidence and sampling. Mineral resources which are not mineral

reserves do not have demonstrated economic viability.

Forward Looking Statements

This document contains "forward-looking information" within the meaning of Canadian securities legislation and "forward -

looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995. This information

and these statements, referred to herein as "forward-looking statements" are made as of the date of this document. Forward-

looking statements relate to future events or future performance and reflect current estimates, predictions, interpretations,

expectations or beliefs regarding future events and include, but are not limited to, statements with respect to: (i) the drill

program completing 12 to 15 drill holes exceeding 12,000 meters of core; (ii) the expectation that the drill program will increase

the Bronson Slope mineral resource and the potential to expand the mineral resource to targets 12,000 meters along strike;

(iii) the observed mineral systems at Iskut being interpreted as high-level expressions of Cu-Au porphyry features along the

district scale structural feature that connects the Quartz Rise, Bronson Slope and Snip North targets; (iv) the copper and gold

concentrations intersected within and on the margins of the quartz-magnetite breccia pipe being evidence the source

intrusion could host a significant mineral system; (v) magnetic surveys indicating a separate intrusive feature is present under

another target which may be another porphyry source; and (vi) the resource estimate in respect of the Iskut Project.

All forward-looking statements are based on Seabridge's or its consultants' current beliefs as well as various assumptions

made by them and information currently available to them. Although management considers these assumptions to be

reasonable based on information currently available to it, they may prove to be incorrect.

Forward-looking statements involve various risks and uncertainties. There can be no assurance that such statements will

prove to be accurate and actual results and future events could differ materially from those anticipated in such statements.

Important factors that could cause actual results to differ materially from Seabridge's plans or expectations include the ris k

that: (i) the geologic formations at the Iskut Project do not conform to the interpretations of data and the geologic models

that are the foundations for such forward -looking statements; (ii) the identified regional trend not being indicative of the

presence of multiple porphyry deposits; (iii) the assumed presence of and c ontinuity of metals at the Project between drill

holes, including at grades estimated in the mineral resource estimate and the other assumptions underlying the resource

estimate; and (iv) the availability of necessary equipment, supplies and personnel for the work programs, and other risks

outlined in statements made by Seabridge from time to time in the filings made by Seabridge with securities regulators.

Seabridge disclaims any intention or obligation to update or revise any forward -looking statements whether as a result of

new information, future events or otherwise, except as otherwise required by applicable securities legislation.

We caution readers not to place undue reliance on these forward-looking statements as a number of important factors could

cause the actual outcomes to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates

assumptions and intentions expressed in such forward-looking statements.
