Foremore Project | Westmore Discovery
Westmore has been one of the quickest grassroots drilling discoveries in recent memory in the Eskay Camp. From being an unknown target as late as 2019, Sassy Gold’s exploration team took Westmore to the drill stage in 2020 after just a few months of very successful field work that returned an abundance of well-mineralized surface samples.
Receding ice and snow had lifted the “cover” at Westmore, exposing veins for the first time in an area of Foremore that had received little or no historical exploration.
Sassy’s initial 2019 surface discovery, returning 15.3 g/t Au to 125.5 g/t Au, and 203 g/t Ag to 1,900 g/t Ag, resulted from a series of six chip and grab samples evenly spaced over 61 meters along an 80-meter exposed quartz vein near the top of Westmore on the northern side (refer to Sept. 4, 2020, news release).
In 2020 prospectors and geologists noted that vein density increased significantly in a southeasterly direction up to 400 meters from the initial discovery, and remained open in multiple directions with visible gold increasingly observed in surface samples.
36 Holes Now Drilled
Two years later, in 2022, Sassy has now completed 36 drill holes at Westmore with results pending for 18 of those holes that formed the summer 2022 campaign. Approximately 8,000 meters of total drilling to date since 2020 has revealed a structurally controlled gold-rich system with multiple vein structures highlighted by the 4Amigos Vein. This vein had a strike length of 160 meters entering 2022 drilling and remained open for expansion to depth and along strike to the west and in particular along strike and downslope to the east toward the glacier.
“We’re clearly in the right neighborhood at Westmore with very promising results at this early stage. The exciting challenge for our team is to find an even richer, thicker part of this mineralized system.
“The Eskay Camp is one of the best addresses in the world for high-grade gold discoveries. It’s a district where it pays to think big, where upside surprises are known to occur given the incredible metal endowment of this region. Potential leverage for our shareholders is enormous given how such a high percentage of Eskay Camp juniors have exploded from our market cap level to $500 million or more in the last five years on important new discoveries.”

The abundance of mineralized veins with pockets of high-grade combined with critical pathfinder elements in drill core (consistent with features recognized on surface) and thick zones of quartz stockworks in drill core suggest the potential for a large orogenic style gold deposit at Westmore.

Large Surface Footprint, Widespread Mineralization
Multiple vein structures have been identified at Westmore covering the granodiorite intrusive (1 km long, 1 km wide) and surrounding country rock. The intrusives depth extent remains unknown but is confirmed by drilling to be >400 meters.
1,026 surface samples collected at Westmore by Sassy, mostly during 2020 and 2021, returned an average grade of 2.65 g/t Au. The top 50 samples averaged 43.16 g/t Au and 271.57 g/t Ag.
High-grade gold and associated silver mineralization is intimately associated with quartz vein hosted disseminated galena, with lesser amounts of disseminated sphalerite and chalcopyrite.

Geochemically, the high-grade veins occurring in the intrusive and the encompassing mafic volcanic rock at Westmore are similar. The associated Au-Ag-Cd-Pb-Te-Zn geochemical signature is recognized in veins occurring within the mafic volcanic unit that flanks the west-northwest side of the Westmore intrusive and on the southeast side of the intrusive where mafic volcanic hosted and very steeply dipping quartz veins have a measured thickness at surface of up to 7.7 m.
Quartz veins and quartz stockworks strike across the granodiorite Westmore intrusive, which still has an unknown depth extent, in an east-west orientation and dip steeply to the north. The original 2019 discovery occurs in a mafic volcanic unit that surrounds this interpreted multi-phased intrusive.
The Right Age
Notably, a recently completed geochronology study puts the time of emplacement of the Westmore intrusive at 189.6 Ma, Early Jurassic. The timing of this magmatic event overlaps with the age of the Brucejack and Snip gold deposits.
The gold-bearing quartz veins from the Westmore discovery zone also contain galena that overlaps in composition with the field of Jurassic-aged galena from the Eskay Creek mine, and these veins crosscut the Westmore granodiorite.
