OD6 Metals (ASX:OD6) has reported gold assays up to 6.31 grams per tonne gold (Au) at its Quinn Fluorspar Project in Nevada, US, which confirms the potential to establish Nevada Carlin-style and epithermal fluorspar-gold targets.
Gold anomalism was identified during fluorspar exploration, with OD6 noting that no prior modern gold exploration has been conducted at the project.
Outcrop rock sampling west of the main Mammoth fluorspar breccia returned results including 6.31g/t, 2.74g/t, 2.23g/t, and 1.61g/t Au, alongside several samples above 0.5g/t Au.
Meanwhile, soil sampling across Mammoth, North Horseshoe Canyon, and Dress Circle flagged gold and pathfinding element anomalies spanning over 8km.
Managing Director Brett Hazelden says the results reinforce the company’s belief that Quinn represents a large and ‘highly fertile’ mineral system.
“While our primary objective remains developing what we believe could become one of the United States’ most significant fluorspar projects, the identification of ‘high-grade’ gold in one of the world’s premier, yet substantially underexplored, gold provinces adds a compelling new dimension,” Hazelden says.
“Importantly, the gold mineralisation appears separate from the fluorspar, preserving the quality of the fluorspar deposits while opening another avenue for value creation.”
At Mammoth, channel sampling returned anomalous gold associated with a stockwork vein system measuring at least 50m by 50m, remaining open to the south, north, and west.
Meanwhile, soil sampling at North Horseshoe returned up to 44 parts per billion Au, coincident with pathfinder elements including arsenic and mercury.
Finally, a 400m by 150m soil anomaly at Dress Circle yielded up to 77ppb Au, with elevated arsenic and mercury.
Located 220km north of Las Vegas, the Quinn Project — acquired by OD6 in June 2026 — sits within Nevada’s Walker Lane epithermal province, near Round Mountain and AngloGold Ashanti’s (NYSE:AU) Beatty District.
While advancing primary fluorspar targets at Mammoth, Horseshoe, and Big Jim, OD6 plans to continue assaying for gold across ongoing exploration programs.
Ongoing workstreams include metallurgical test work and geological and structural mapping, with bulk sample permit applications and preparations for maiden drilling in the pipeline ahead of resource definition and development studies.
OD6 Metals is a critical minerals explorer and developer with projects spanning fluorspar, rare earth elements, and copper across the US and Australia.
