<div id="readability-page-1"><article>&#34;Newco&#34; to Unlock Value of Advanced-Stage, High Grade Gold Project to Seabridge ShareholdersToronto, Ontario--(Newsfile Corp. - December 16, 2025) - Seabridge Gold Inc. (TSX: SEA) (NYSE: SA) (&#34;Seabridge&#34; or the &#34;Company&#34;) announces today its intention to spin-out its wholly owned subsidiary, Seabridge Gold (NWT) Inc. (to be renamed &#34;Valor Gold&#34;) which owns 100% of the Courageous Lake Gold Project (&#34;Courageous Lake&#34; or the &#34;Project&#34;), located in Canada's Northwest Territories. Following the spin-out, Valor Gold will be focused on advancing the Project through exploration, engineering and permitting. It is contemplated that Valor Gold shares would be distributed to Seabridge shareholders and listed on, at least, one major public stock exchange. Seabridge would continue focusing primarily on its KSM gold/copper project and its other exploration assets.Courageous Lake is one of Canada's largest undeveloped gold projects with total contained gold inventory, comprising Measured and Indicated Resources, of 11.0 million oz of gold (145.2 million tonnes at an average grade of 2.36 grams per tonne), plus an additional 3.3 million ounces of gold in the inferred category (40.6 million tonnes at 2.52 grams per tonne). The reported measured and indicated resources incorporate 2.8 million ounces of proven and probable reserves (33.9 million tonnes at 2.6 grams per tonne) which would make it one of the highest-grade open pit gold projects in Canada. Rudi Fronk, Seabridge's Chair and CEO stated: &#34;We have always believed, as we have shown in our recent studies, that Courageous Lake is a valuable project with enormous additional district potential in a Tier 1 jurisdiction. We also believe that Courageous Lake is being attributed little to no value in the price of Seabridge shares today.&#34;Fronk continued: &#34;A spin-out of Courageous Lake should give our shareholders more optionality around a gold asset that has been overshadowed for too long by KSM, which remains our primary development focus. We believe that this reorganization will bring attention to the potential of Courageous Lake and unlock additional value for Seabridge shareholders while allowing them to continue having the same exposure to all of Seabridge's assets.&#34;In February 2024, Seabridge filed an updated NI 43-101 technical report for Courageous Lake that included the results of an updated Preliminary Feasibility Study (the &#34;2024 PFS&#34;) and a new Preliminary Economic Assessment (the &#34;2024 PEA&#34;) that evaluates a conceptual expansion of the Courageous Lake open pit beyond the 2024 PFS mine plan. Seabridge believes there is further upside potential with inclusion of potential high-grade, near-surface, non-refractory satellite pits nearby, similar to the Walsh Lake deposit, discussed below, and exploration on the ~500km2 land package, of which less than 15% has been explored to date. Courageous Lake 2024 PFS Highlights at US$1,850/oz gold:<ul><li>Mine Life: 12.6 years</li><li>Total Payable Gold: 2.5Moz</li><li>Average Annual Payable Gold: 201koz</li><li>Cash Cost: US$863/oz</li><li>AISC: US$999/oz</li><li>Initial Capital: US$747 million</li><li>After-Tax NPV (5%): US$523 million</li><li>IRR: 20.6%</li><li>Payback period: 2.8 years</li></ul>At US$2,500/oz gold, the after tax NPV (5%) increases to US$1.1 billion, the IRR to 38.2% and the payback period drops to 1.6 years.Courageous Lake Mineral Resource Estimate at a 0.8g/t Au Cut-Off Grade:<table><tbody><tr><td>Class</td><td>Tonnage (ktonnes)</td><td>Au Grade (g/t)</td><td>Au Metal (koz)</td></tr><tr><td>Measured</td><td>6,007</td><td>2.84</td><td>548</td></tr><tr><td>Indicated</td><td>139,167</td><td>2.34</td><td>10,449</td></tr><tr><td>Measured + Indicated</td><td>145,174</td><td>2.36</td><td>10,997</td></tr><tr><td>Inferred</td><td>40,603</td><td>2.52</td><td>3,286</td></tr></tbody></table>In addition to the above stated resources, the project also hosts a satellite deposit (Walsh Lake) that has an inferred resource of 4.13 MT at 4.18 g/t containing 555,000 ounces of gold (the &#34;Walsh Lake Resource Estimate&#34;). Next steps for the spinout of Courageous are anticipated to include:- Formation of Valor Gold: Full details of the proposed arrangement will be released in due course. Seabridge management will continue to manage Courageous Lake until a dedicated management team and board of directors are installed at Valor Gold. It is Seabridge's intention that Seabridge employees will not have any involvement in the day-to-day operations of Valor Gold. - Financing: Seabridge plans to spinout Valor Gold with sufficient funds in its treasury for immediate needs and working capital, but Valor Gold may consider completing a private financing to raise capital for 2026 and 2027 work programs.- Exploration Potential: Once the spinout is completed, Valor Gold intends to complete a targeted drill program to further explore for satellite deposits analogous to Walsh Lake having the potential to materially improve economics.- Public Listing: It is expected that the spinout of the Valor Gold shares to Seabridge shareholders will be completed by way of a plan of arrangement under the provisions of the Canada Business Corporations Act. Upon closing of the proposed plan of arrangement, Valor Gold will become a reporting issuer in each of the provinces and territories of Canada where Seabridge is currently a reporting issuer, and it is expected that Valor Gold will seek a public listing, but there is no assurance that such a listing will be obtained. Seabridge intends to update the market on progress regarding this transaction in Q1 2026.Readers are cautioned that the reorganization plan described herein is a statement of intention only at this point and there can be no assurance that the proposed spinout will occur, or that it will occur in the manner and timeline described in this press release. Completion of the proposed transaction is subject to a number of conditions, which will include the approval of Seabridge's board, Seabridge shareholder approval, court approval and regulatory approvals.Further information regarding the mineral resource and reserve estimates, the 2024 PFS, and the 2024 PEA and the Walsh Lake Resource Estimate is provided in the technical report titled &#34;Courageous Lake Pre-feasibility Study and Preliminary Economic Assessment, NI 43-101 Technical Report&#34;, with an effective date of January 5, 2024, filed on SEDAR+ under Seabridge's profile.The 2024 PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the results of the 2024 PEA will be realized. Mineral Resources in the 2024 PEA mine plan are not Mineral Reserves and do not have demonstrated economic viability. The 2024 PEA evaluates a conceptual expansion beyond the PFS pit and includes Inferred Mineral Resources. See the 2024 PEA for relevant assumptions, parameters, and risks.About Seabridge Gold Seabridge holds a 100% interest in several North American gold projects. Seabridge's principal asset, the KSM project, and its Iskut projects are located in Northwest British Columbia, Canada's &#34;Golden Triangle&#34;, 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 is in the Yukon Territory.
