M&I GOLD RESOURCE INCREASES 38% TO 11 MILLION OZ
AFTER-TAX NPV (5%) OF US$523 MILLION, 20.6% IRR AND 2.8 YEAR PAYBACK
AISC OF US$999/OZ IN LOWEST QUARTILE OF WORLD GOLD COUNCIL COST CURVE
12.6 YEAR MINE LIFE AVERAGING 201,000 OZS OF GOLD PRODUCTION PER YEAR

Toronto, Ontario--(Newsfile Corp. - January 16, 2024) - Seabridge Gold (TSX: SEA) (NYSE: SA) announced today the results of an updated Preliminary Feasibility Study (the "2024 PFS") for its 100%-owned Courageous Lake project located in Canada's Northwest Territories. The 2024 PFS all open pit mine plan shows a considerably more sustainable and profitable mining operation than its 2012 predecessor, with reduced initial capital, lower strip ratio, higher grade and smaller mine footprint.

The 2024 PFS led by Ausenco demonstrates the production of 2.5 million ounces of gold over the initial 12.6 year life of mine. A stand-alone analysis of the potential expansion below the 2024 PFS mine plan will be included as a Preliminary Economic Assessment ("2024 PEA") forming a separate part of Technical Report (the "Report") prepared in accordance with NI 43-101, and which includes evaluating the potential extension of the mine. The Report will be filed within the next 45 days.

Commenting on the study, Seabridge Chairman and CEO Rudi Fronk said: "We now have a second valuable 10 million plus ounce gold resource project in a safe jurisdiction. The project consists of an entire greenstone belt which has prospective shallow drill results and gold showings along its 54 km length. As we move towards a joint venture on our KSM project, we will be shifting our attention to Courageous Lake's potential to generate considerable additional shareholder value."

Mr. Fronk noted that the PEA establishes the potential for a much longer mine life. "The PFS uses less than 30% of the estimated M&I gold resource. The PEA includes inferred resource requiring more drilling as well as additional engineering work to qualify as a PFS. However, we are confident that the PEA reflects the potential for a greatly extended mine life and that the entire estimated M&I resource represents a meaningful call on gold for our shareholders."

Notable improvements in the 2024 PFS compared to the 2012 PFS include:

  • 73% increase in after-tax NPV5% to US$523 million from US$303 million in 2012
  • 50% reduction in initial capital from US$1,522 million to US$747 million
  • Increased after-tax IRR from 7.3% to 20.6%
  • Reduced capital payback period from 11.2 years to 2.8 years
  • Average gold reserve grade increased 19% from 2.2 g/t to 2.6 g/t
  • Life of mine strip ratio reduced by 39% from 12.5 to 7.58
  • 38% increase in estimated measured and indicated gold resources from 8.0 million to 11.0 million ounces.

2024 PFS

The 2024 PFS was led by Ausenco Engineering Canada ULC ("Ausenco"), together with the support of Moose Mountain Technical Services ("MMTS"), SRK Consulting (Canada) Inc. ("SRK"), ERM Consultants Canada Ltd. ("ERM"), Tetra Tech Canada Inc. ("Tetra Tech"), and WN Brazier Associates Inc. ("Brazier"), all of which are independent of Seabridge Gold.

The 2024 PFS open pit mine plan produces 2.5 million ounces of gold over 12.6 years with a Base Case after-tax NPV5% of US$523 million using the 3-year trailing average gold price of US$1,850/oz and consensus long term forecast forex of 0.74 US$/C$. Sensitivity of the economic results to the gold price assumption is shown in Table 1.

The 2024 PFS mines 33.9 million tonnes of proven and probable reserves at an average grade of 2.61 grams of gold per tonne feeding a 7.5 ktonnes per day processing plant (2.7 million tonnes per year). The 12.6-year mine life produces 2.5 million ounces at an average annual rate of 201 koz of payable gold per year. Average life of mine cash operating costs are US$863 per ounce, and all-in sustaining costs (AISC) are US$999/Oz (lowest quartile of the World Gold Council AISC cost curve).

The Courageous Lake property is located 240 km northeast of Yellowknife NWT, Canada and is situated within the Courageous Lake greenstone belt (CLGB) in the Slave Structural Province. The property is a collection of mineral leases and mining claims that trend north-south along the approximately 54 km length of the CLGB. The property includes the past gold producing properties of the Salmita mine operated by Giant Yellowknife Mines, and the Tundra mine operated by Royal Oak Mines.

The project site will be accessed via spur winter road connecting to the Tibbitt to Contwoyto Winter Road (TCWR) that is normally open from late January/early February until the end of March of each year and services the nearby Ekati and Diavik mines.

The 2024 PFS mine plan uses an open pit truck and shovel operation. Mill feed is processed onsite by crushing, grinding and flotation. Flotation concentrate is pressure oxidized and cyanide leached to produce a gold doré. Waste rock will be generated during the mining of economical ore and will be directly hauled to the co-placement storage facility (CPSF) along with flotation tailings. Flotation tailings will be co-placed with waste rock while neutralized leach tailings will be placed in a separate facility. The 2024 PFS layout is shown in Figure 2.

2024 Mineral Resource Estimate

The Courageous Lake Project includes two deposits: the Courageous Lake deposit, and the Walsh Lake deposit. Only the Courageous Lake deposit is used in the 2024 PFS.

The Courageous Lake Mineral Resource estimate is derived from a database containing 616 drill holes with assays collected from 127,168.61 m of drillcore. Courageous Lake grade interpolation was carried out using both indicator probabilities and relative elevations within 13 mineralized domains to constrain the inverse distance squared interpolations within blocks with dimensions of 5m x 5 m x 5 m.

Measured and indicated resources are estimated at 145.2 million tonnes at an average grade of 2.36 grams per tonne containing 11.0 million ounces. For comparison, the 2012 PFS reported measured and indicated gold resources of 8.0 million ounces contained in 107.3 million tonnes at an average grade of 2.31 grams per tonne. The increase in contained tonnes and grade is a result of the incorporation of drilling completed after the 2012 Mineral Resource Estimate, as well as refinement to the modelling methodology.

The Walsh Lake Mineral Resource estimate uses a database containing 92 drill holes with 17,533.7 m of assayed length. Walsh Lake grade uses Indicator probabilities and inverse distance squared interpolation to estimate the gold grades into blocks with dimensions of 3 m x 3 m x 3 m.

Mineral Resource estimates for each of the deposits that comprise the Courageous Lake Project are summarized in Table 3 and Table 4.

Mine Planning

Lerchs-Grossman ("LG") pit shell optimizations were used to define the mine plans in the 2024 PFS. The pit optimizations incorporated estimated costs for mining, processing, tailings management, general and administrative and process recoveries. Waste to ore cut-offs were determined using a gold price of US$1,400 per ounce. The 2024 PFS pit was restricted from mining below the base of the permafrost to minimize the ingress of saline groundwater.

Estimated proven and probable Mineral Reserves, including mining dilution within the ultimate pit limit uses a Net Smelter Return (NSR) cut-off grade of C$49.66/t milled.

Notes:

  1. The Mineral Reserve estimates were prepared by Jesse Aarsen, P.Eng. (who is also the independent QP for these Mineral Reserve estimates), reported using the 2014 CIM Definition Standards and 2019 CIM Best Practices Guidelines, and have an effective date of January 5, 2024.
  2. Mineral Reserves are based on the 2024 PFS open pit Life of Mine plan.
  3. Mineral Reserves are mined tonnes and grade; the reference point is at the primary crusher and includes consideration for operational modifying factors.
  4. Mineral Reserves are reported at NSR cut-off grade C$49.66/t: metal price of US$1,400/oz Au, at a currency exchange rate of US$0.77 per C$; Off-site costs (smelting, refining, transport, and insurance) doré terms are US$3.5/oz off-site costs (refining, transport and insurance), 100% Au payable; metallurgical recovery projections vary depending on metallurgical domain and metal grades and are based on metallurgical test work.
  5. Mineral Reserves account for mining loss and dilution.
  6. Mineral Reserves are a subset of the Mineral Resource.
  7. Numbers have been rounded.

The 2024 PFS produces an average of 250,000 ounces of gold per year in the first five years of operation and an average of 201,000 ounces per year over the life of mine. High grade ore is exposed with minimal pre-stripping.

Mineral Processing

Seabridge has conducted seven metallurgical testing programs since 2003. The selected flowsheet includes a three-stage crushing circuit with the crushed product reporting to the crushed material stockpile. Mineralized material is reclaimed to a grinding circuit consisting of a ball mill circuit operating in closed circuit with a cyclone cluster. Classified material reports sequential stages of rougher flotation, where concentrate is separated from the gangue material and fed to cleaner flotation. In the cleaning circuit, the concentrate grades are upgraded prior to further size reduction in a regrind ball mill operating in closed circuit with a cyclone cluster. Cleaner tailings combine with rougher tailings for thickening before being discharged to the CPSF.

Overflow from regrind cyclones undergoes acidulation and pre-oxidation stages followed by the pressure oxidation circuit to oxidize the concentrate. The oxidized slurry is leached with cyanide and then washed in six stages through a CCD circuit. The resulting pregnant solution is processed using a Merrill-Crowe treatment by adding zinc powder to precipitate gold and silver. The precious metals precipitate will be smelted on site to produce gold-silver doré bars. Overall gold recovery is projected at 89.3%.

The simplified process flow diagram for the Courageous Lake Project is shown in Figure 4.

2024 PEA Expansion

The 2024 PEA is a standalone mine plan that evaluates a conceptual expansion of the Courageous Lake open pit below the base of the permafrost after the 2024 PFS reserve has been completely mined out. None of the Mineral Resources used in the 2024 PEA mine plan have been used in the 2024 PFS.

The 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 PEA will be realized. Mineral Resources in the PEA mine plan are not Mineral Reserves and do not have demonstrated economic viability.

The 2024 PEA results summarized in Table 8 show 3.26 million ounces of payable gold are produced over a 15.9-year mine plan at an average annual rate of 205,000 ounces of gold per year with an NPV5% of US$194 million and an AISC of US$ 1,316/Oz.

Cautionary note to U.S. Investors concerning estimates of Mineral Reserves and Mineral Resources

All reserve and resource estimates reported by Seabridge were estimated in accordance with the Canadian National Instrument 43-101 and the Canadian Institute of Mining, Metallurgy 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 "proven 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.

Cautionary Note Regarding Forward-Looking Information

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, expectations or beliefs regarding future events and include, but are not limited to, statements with respect to: (i) the estimated amount and grade of mineral reserves and mineral resources, including the cut-off grade; (ii) estimates of the capital costs of constructing mine facilities and bringing a mine into production, of operating the mine, of sustaining capital, of strip ratios and the duration of financing payback periods; (iii) the estimated amount of future production, both ore processed and metal recovered and recovery rates; (iv) estimates of operating costs, life of mine costs, net cash flow, net present value (NPV) and economic returns from an operating mine; and (v) the completion of the full Technical Report, including a Preliminary Economic Assessment, and its timing. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives or future events or performance (often, but not always, using words or phrases such as "expects", "anticipates", "plans", "projects", "estimates", "envisages", "assumes", "intends", "strategy", "goals", "objectives" or variations thereof or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking statements.

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. The most significant assumptions are set forth above, but other assumptions include: (i) the presence of and continuity of metals at the Project at estimated grades; (ii) the geotechnical and metallurgical characteristics of rock conforming to sampled results; (iii) the quantities of water and the quality of the water that must be diverted or treated during mining operations; (iv) the capacities and durability of various machinery and equipment; (v) the availability of personnel, machinery, equipment at estimated prices and within the estimated delivery times; (v) currency exchange rates; (vi) metals sales prices; (vii) appropriate discount rates applied to the cash flows in the economic analysis; (viii) tax rates and royalty rates applicable to the proposed mining operation; (ix) the availability of acceptable financing under assumed structure and costs; (ix) anticipated mining losses and dilution; (x) metallurgical performance; (xi) reasonable contingency requirements; (xii)success in realizing proposed operations; (xiii) receipt of permits and other regulatory approvals on acceptable terms; and (xiv) the successful conclusion of consultation with impacted indigenous groups. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect. Many forward-looking statements are made assuming the correctness of other forward-looking statements, such as statements of net present value and internal rates of return, which are based on most of the other forward-looking statements and assumptions herein. The cost information is also prepared using current values, but the time for incurring the costs will be in the future and it is assumed costs (and metals prices) will remain stable over the relevant period.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be achieved or that assumptions do not reflect future experience. 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. These risk factors may be generally stated as the risk that the assumptions and estimates expressed above do not occur as forecast, but specifically include, without limitation: risks relating to variations in the mineral content within the material identified as mineral reserves or mineral resources from that predicted; variations in rates of recovery and extraction; the geotechnical characteristics of the rock mined or through which infrastructure is built differing from that predicted, the quantity of water that will need to be diverted or treated during mining operations being different from what is expected to be encountered during mining operations or post closure, or the rate of flow of the water being different; developments in world metals markets; risks relating to fluctuations in the Canadian dollar relative to the US dollar; increases in the estimated capital and operating costs or unanticipated costs; difficulties attracting the necessary work force; and risks relating to the costs of other energy sources; increases in financing costs or adverse changes to the terms of available financing, if any; tax rates or royalties being greater than assumed; changes in development or mining plans due to changes in logistical, technical or other factors; changes in project parameters as plans continue to be refined; risks relating to receipt of regulatory approvals or the conclusion of successful consultation with impacted indigenous groups; changes in regulations applying to the development, operation, and closure of mining operations from what currently exists; the effects of competition in the markets in which Seabridge operates; operational and infrastructure risks and the additional risks described in Seabridge's Annual Information Form filed with SEDAR in Canada (available at www.sedar.com) for the year ended December 31, 2022 and in Seabridge's Annual Report Form 40-F filed with the U.S. Securities and Exchange Commission on EDGAR(available at www.sec.gov/edgar.shtml). Seabridge cautions that the foregoing list of factors that may affect future results is not exhaustive.

When relying on our forward-looking statements to make decisions with respect to Seabridge, investors and others should carefully consider the foregoing factors and other uncertainties and potential events. Seabridge does not undertake to update any forward-looking statement, whether written or oral, that may be made from time to time by Seabridge or on our behalf, except as required by law.

None of the Toronto Stock Exchange, New York Stock Exchange, or their Regulation Services Providers accepts responsibility for the adequacy or accuracy of this release.
