OD6 Metals (ASX: OD6) has rediscovered the historically significant high-grade Big Jim fluorspar lode at its Quinn project in Nevada.

Initially worked in the 1930s, Big Jim has become a significant new drill target within a growing district-scale fluorspar system.

MD, Brett Hazelden, said Big Jim complements the existing nearby Mammoth and Horseshoe discoveries for resource drill out.

“Through some clever geological detective work and historic descriptions dating back to the 1940s, the Nevada team was able to narrow the search area for the Big Jim fluorspar lode,” he said.

“We are very excited to announce that this has now been located and presents a third extensive fluorspar system, with Horseshoe and Mammoth, on the Quinn Project to target for the drill out.

“The visual estimates of size and grade are consistent with historic reports and Big Jim perhaps is our highest-grade target to date.

“This discovery validates our ambition to be a US-based high-grade fluorspar developer coinciding with increasing strategic demand for US domestic supply.”

Big Jim was re=located through targeted field reconnaissance with extensive high-grade system confirmed including massive fluorspar exposed at surface, plus a tunnel inferred to be the Big Jim lode:

Metallurgical samples have now been collected and testworks underway for further optical sorting, crushing, grinding and flotation.

OD6 announced an exclusive option agreement to acquire the Quinn fluorspar project in early March.

The project is located approximately 220km north of Las Vegas and offers very high-grade fluorspar mineralisation identified at the Mammoth and Horseshoe projects.

Big Jim is located approximately one km NNE of the Horseshoe fluorspar deposit.

The US is currently 100% reliant on imports of fluorspar. Fluorspar is listed on the US Critical Minerals list with applications in battery technologies, AI chip manufacture, nuclear fuels industry, aerospace and defence technologies.

OD6 is up 15.2% to 19.0c. Mkt cap $47.74M.
