Seabridge solves 3 Aces continuity mystery

Long hidden geological controls solved, shapes plans for future drilling of high-grade gold target.

Seabridge Gold Inc. Feb. 14 announced the results from the 2023 drill program established a new model for the mineralization associated with the main high-grade gold target at its 3 Aces project in Yukon, Canada, giving the company a clear path forward for follow-up evaluation and resource delineation in the coming season.

With the added data from 7,759 meters of core and reverse circulation drilling completed within the Central Core Area (CCA) at 3 Aces last year, an updated 3D model has been assembled that combines Seabridge's drilling data and historical programs into a framework that shows the likelihood of continuous mineralization between previously isolated historical deposits in the area.

"Previous operators encountered challenges connecting and extending target zones in the CCA," said Seabridge Gold CEO Rudi Fronk. "Our team's comprehensive and detailed work has recognized controls that appear to have resolved this continuity issue."


Compiling the data, Seabridge was able to confirm from its 2023 program that the extensions of historical discoveries, including localized high-grade zones, were located within favorable parts of the regional fold structure.

Found between contacts of thick phyllite (a fancier cousin of shale) sequences and coarse interbedded sandstone and conglomerate, second-generation folding has ultimately produced discrete dilation zones or various degrees of differing space along faults or fractures on second-generation synforms and antiforms (hilled earth or bowled earth), where continuous gold mineralization and locally high-grade intervals are found.


Drill testing was completed around the Spades, Hearts, and Clubs zones, with detailed surface and drill hole observations providing better control of the stratigraphy and location of second-generation folded structures.

Select drill results from the 2023 program that helped toward this conclusion include:


32 meters averaging 1.1 grams per metric ton gold from 262.1 meters in 3A23-373 (Hearts).

3.1 meters averaging 1.93 g/t gold from a depth of 81.4 meters in hole 3A23-359 (Hearts NE).

0.7 meters averaging 4.6 g/t gold from surface in 3A23-361 (Hearts W).

10.6 meters averaging 2.69 g/t gold from 42.7 meters in 3A23-362 (Spades SE).


15.3 meters averaging 1.83 g/t gold from 19.8 meters in 3A23-381 (Clubs).

Having a better understanding of the stratigraphy has given Seabridge a clear target for 2024.

"This year's breakthrough now gives us the tools to identify additional promising targets and expand known gold zones at 3 Aces," said Fronk. "We now see a path for bringing the property's extensive gold mineralization into resource configurations."
