High recoveries at Seabridge Gold (NYSE: SA) Snip North metallurgical tests

Rhea-AI Filing Summary

Seabridge Gold Inc. reported strong metallurgical results from its first test program on drill core from the Snip North deposit at its 100%-owned Iskut project in British Columbia’s Golden Triangle. The work used the same flotation flowsheet as the company’s KSM project and showed similar metallurgy to the Mitchell deposit.

Locked cycle flotation tests produced copper-gold-molybdenum concentrates grading about 20%–28% copper and 83–525 g/t gold from relatively low head grades, with copper and gold recoveries to concentrate described as excellent. Follow-up cyanide leach tests on pyritic concentrates lifted overall gold recoveries to between 85.3% and 92.7%.

Initial bond work index results of 9.9–11.9 kW-hr/tonne indicate the material is relatively soft and suitable for conventional SAB or SABC grinding circuits. Management states these robust results provide a strong foundation to support an upcoming maiden resource estimate for Snip North.

Insights

Mining project development analyst

Snip North tests show high gold recoveries and conventional processing potential.

The testwork indicates Snip North mineralization responds well to standard flotation, yielding copper-gold-molybdenum concentrates with high copper grades and strong gold recoveries from modest head grades. The reported bond work indices suggest relatively soft ore, compatible with widely used grinding circuits.

Combined flotation and cyanide leach tests deliver overall gold recoveries in the mid‑80s to low‑90s percent range, which is competitive for gold-copper systems. Management links these results directly to preparing a maiden resource estimate, so future technical reports on Snip North will be key to understanding potential scale and economics.

Seabridge Gold Announces Results from Metallurgical
Test Program at Snip North

Toronto, Canada… Seabridge Gold Inc. ("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.

Highlights

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.

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."

FAQ

What did Seabridge Gold (SA) announce about the Snip North deposit?

Seabridge Gold announced robust metallurgical results from its first test program on Snip North drill core. Tests showed strong flotation performance and high overall gold recoveries, supporting plans to advance the deposit toward a maiden resource estimate within the broader Iskut project.

How good are the gold recoveries in Seabridge Gold’s Snip North tests?

Overall gold recoveries at Snip North reached about 85.3% to 92.7% after flotation and cyanide leaching. These results indicate the mineralization responds well to standard processing, which can be important for future economic studies and project design decisions at the Iskut project.

What concentrate grades were achieved in Seabridge Gold’s Snip North program?

Locked cycle flotation tests produced copper-gold-molybdenum concentrates grading roughly 20%–28% copper and 83–525 g/t gold. These grades were obtained from relatively low head grades, indicating efficient upgrading of the ore through flotation at the Snip North deposit.

Why are the Snip North metallurgical results important for Seabridge Gold (SA)?

The results show Snip North mineralization is amenable to conventional flotation and grinding, with high metal recoveries. Management states this provides a strong technical foundation to support an upcoming maiden resource estimate, an important step in advancing the Iskut gold-copper project.

What do the bond work index results imply for Snip North processing?

Bond work index values between 9.9 and 11.9 kW-hr/tonne indicate relatively soft mineralization at Snip North. This suggests the ore should be suitable for conventional SAB or SABC grinding circuits, which can simplify plant design and potentially help manage operating costs.

Is molybdenum recovery possible from Seabridge Gold’s Snip North material?

Test results indicate molybdenum can be recovered into the flotation concentrate, suggesting a separate molybdenum concentrate may be produced. The company also notes that copper and gold grades in the locked cycle concentrates are expected to increase further after molybdenum separation.
