The 3Ts project is located approximately 120 km southwest of Vanderhoof in central British Columbia. The project consists of six contiguous claim groups: the Tsacha, Tam, Taken, Tommy Lakes, Bot, and Blackwater South properties. Sandstorm holds a 2% NSR royalty on the Tsacha claim and the Tommy vein system.
The project covers an epithermal quartz-carbonate vein system where more than a dozen individual mineralized veins have been identified. The project is underlain by a near-horizontal micro-diorite sill which bisects the vein systems into an upper and lower portion. The upper portion of the veins above the sill have been modelled as in-pit resources, while the vein extensions below the sill are considered as an underground resource.
Various exploration programs were conducted at the project between 2014 and 2022, including magnetic and 3D induced polarization surveys, soil sampling, geological mapping, and drilling campaigns.
In August 2022, an updated Mineral Resource Estimate was announced that incorporated results from the drilling program on the Tommy and Ted-Mint vein systems. The combined in-pit and underground components of the Tommy and Ted-Mint vein systems contain a total Inferred Resource estimate of 4.5 Mt grading 3.6 g/t gold and 96.3 g/t silver containing 522 koz gold and 13.8 Moz silver (cut-off grade of 0.4 g/t AuEq in-pit and 2.0 g/t AuEq underground).
