Endurance Gold Corp (CVE: EDG) (OTCMKTS: ENDGF) (FRA: 3EG) just reported its highest-grade antimony intercept to date at British Columbia’s Reliance Gold Project. The new assay result comes as the province has been seeing a significant surge of interest in the critical mineral.
On Tuesday, the Canadian junior reported intercepting 5.12 per cent antimony (Sb) and 5.63 grams per tonne gold (Au) over 3.3 metres. Five per cent Sb is broadly considered to be a high grade in a core sample and anything above is viewed as exceptional.
“This same hole also hit 11.21 g/t Au over 3.0 metres,” the company noted in a social media post.
Endurance has drilled eight holes during this year’s campaign for a total of 3,610 metres. Additional samples are currently being assessed at a laboratory in North Vancouver.
This intercept is not the only promising Sb sample that Reliance has yielded in recent months as the metalloid element continues to pull attention.
Not long ago, Endurance pulled a notable grab sample enriched with visible stibnite crystals. It contained nearly 7 per cent antimony, thereby highlighting the project’s critical mineral potential.
Endurance’s President and CEO, Robert T. Boyd, currently serves as a Director at the Canadian Mining Hall of Fame.

BC miners hone in on antimony mineralization
Endurance is not the only one increasing its Sb focus in BC. Maxus Mining Inc (CNSX: MAXM) (FRA: R7V) just staked over 1,800 hectares to expand its antimony mining footprint at the Quarry project in the north-central area of the province. This recent development follows the junior acquiring a cohort of British Columbia antimony and tungsten projects.
“By diversifying our portfolio to include minerals essential for emerging technologies and the future of energy, we are uniquely positioned to capitalize on these evolving markets,” said chief executive Scott Walters on Jun. 5 as the land grab move was announced.
Australia’s Equinox Resources (ASX: EQN) is another. This junior miner is currently pursuing antimony at the Alturas project in the province’s Slocan Mining District. Rock chip samples taken from this site have yielded grades as high as 69.98 per cent Sb.
Also Canagold Resources Ltd (TSE: CCM) (OTCMKTS: CRCUF) (FRA: CANA), developer of the New Polaris antimony project in the northwest corner of British Columbia.
“This valuable metal has the potential to create a new revenue stream that could add substantial value with minimal additional costs,” Canagold’s CEO Catalin Kilofliski recently said.
Antimony has become a hot commodity over the past year, primarily due to recently implemented Chinese export restrictions. Supply disruptions in Russia, Myanmar and other nations have also contributed to the unprecedented demand and price. It went from being valued at a mere US$12,000 per ton in early 2024 to approximately US$45,000 per ton.
