Seabridge Develops New Gold Deposition Model for 3 Aces Project

The challenge of finding continuity appears to be resolved

Toronto, Ontario--(Newsfile Corp. - February 14, 2024) - Seabridge Gold (TSX: SEA) (NYSE:SA) today announced that 2023 drill results at our wholly owned 3 Aces project in Canada's Yukon have successfully confirmed the key parameters controlling gold deposition on the property and provided a clear set of directions for follow-up evaluation and resource delineation. Last year's program completed 7,759 meters of core and reverse circulation drilling within the Central Core Area of the 3 Aces project.

An updated 3-dimensional model has now been built that brings together results from our drilling and historical drill programs to indicate the likelihood of continuous mineralization between previously isolated historical deposits in the Central Core Area (CCA). Our 2023 drill program confirmed these extensions of historical discoveries, including localized high-grade zones, within the favorable parts of the regional fold architecture. At contacts between thick phyllite sequences and coarse interbedded sandstone and conglomerate, second generation folding (F₂) has produced discrete dilation zones on F₂ synforms and antiforms where continuous gold mineralization and locally high-grade intervals are found.

Commenting on this year's program, Rudi Fronk, Seabridge Chairman and CEO, noted "previous operators encountered challenges connecting and extending target zones in the CCA. Our team's comprehensive and detailed work has recognized controls that appear to have resolved this continuity issue. This year's breakthrough now gives us the tools to identify additional promissing targets and expand known gold zones at 3 Aces. We now see a path for bringing the property's extensive gold mineralization into resource configurations."

Drill testing in 2023 was completed around the historical Spades, Hearts, and Clubs zones. Detailed surface and drill hole observations have provided better control on the stratigraphy and location of the F₂ structures. Gold concentrations are found consistently in the F₂ structures. Where these fold structures encounter the significant competency differences between phyllite and sandstone, open spaces are created through dilation of the rock mass, providing a trap for the deposition of gold-bearing massive quartz veins or quartz-arsenopyrite breccia. These fold features are also recognized outside of the preferred stratigraphic contact, but generally contain narrower intervals at lower gold grades. Following these marginal grade fold features toward stratigraphic contacts is expected to lead to new discoveries.

While the stratigraphic contact and F₂ structures remain the principal control on gold concentrations, we continue to evaluate other potential traps in the system.

Select drill results from the 2023 program include:

Results reported herein are estimated to be 80% or better of true widths for the targeted feature, having been constrained by the stratigraphic section defined on the property.

Rigorous quality control/quality assurance protocols were used in this drilling program, consisting of blind blank, duplicate and certified reference standards inserted in the sample submissions. Assays were preformed by Bureau Veritas laboratory in Vancouver BC with all intervals being analysed by 50g lead collection fire assay fusion and 35 element ICP-EM. Select intervals are reanalyzed using 500g samples screened through 150 mesh screens producing fire assays for the coarse fraction and fine fraction with gold reported for both fractions and the total of the sample.

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 by National Instrument 43-101. Mr. Threlkeld has reviewed and approved this news release.
