Seabridge Gold Announces Results from Metallurgical Test Program at Snip North

Toronto, Ontario--(Newsfile Corp. - March 2, 2026) - Seabridge Gold Inc. (TSX: SEA) (NYSE: SA) ("Seabridge") today announced robust results from its inaugural metallurgical test program on drill core samples from the Snip North Deposit, one of the targets on the 100% owned Iskut Gold-Copper Project in BC's Golden Triangle. The program confirms that Snip North mineralization responds very well to conventional flotation and excellent recoveries can be expected.

A total of 10 drill-core interval samples and four composite samples from the Snip North deposit taken from the 2025 exploration program have been tested at ALS Metallurgy in Kamloops, BC, representing the first systematic metallurgical assessment of the Snip North deposit. The test procedures followed the flotation flow sheet established for Seabridge's KSM Project. Snip North metallurgy is similar to the Mitchell deposit.

Locked cycle tests (LCTs) at a primary grind size of 80% passing approximately 130 µm summarized in Table 1 show copper-gold-molybdenum concentrates with grades ranging from 20% to 28% Copper and 83 g/t to 525 g/t gold from samples with head grades ranging from 0.04% to 0.26% Copper and 0.4 g/t to 1.21 g/t gold. Gold and copper recovery to the bulk flotation concentrate was excellent.

Molybdenum recovery indicates that a separate molybdenum concentrate can also be produced. Copper and gold grades in the LCT concentrates are expected to increase further after molybdenum concentrate separation.

Cyanide leaching completed on the first three pyritic concentrates from LCTs had excellent recoveries as shown in Table 2 with overall gold recoveries increasing to between 85.3% and 92.7%.

Initial bond work index tests results ranged from 9.9 to 11.9 kW-hr/tonne indicating that mineralization is generally soft and will be suitable for conventional SAB or SABC grinding circuits.

These results confirm a robust metallurgical response to flotation and will support the development of a maiden resource statement for Snip North.

Commenting on the study, Seabridge Chair and CEO Rudi Fronk said: "These robust metallurgical results from the Snip North maiden test program provide a strong foundation to support the upcoming maiden resource estimate.
