OD6 Metals (ASX:OD6) expands Quinn Fluorspar Project in Nevada

OD6 Metals has expanded its Quinn Fluorspar Project in Nevada following a review of historic geological data, government archives and regional fluorspar occurrences.

The company has increased its landholding from 48 original optioned mining claims to 226 State of Nevada Mining Claims covering approximately 4,670 acres, or 1,890 hectares, across seven project areas, adding four new project areas and recorded historic fluorspar occurrences.

Highlights

• Mining claims increased from 48 to 226, covering approximately 4,670 acres, or 1,890 hectares.
• Four new project areas have been added, Blue Bell, Bonanza, El Cortez and Bruno.
• The expanded project area contains 20 recorded historic fluorspar occurrences.
• Historic United States Geological Survey sampling at Blue Bell included one assay returning 88.9% CaF₂.
• Historic mapping at Bonanza identified two CaF₂ bearing breccia bodies extending more than 200m and 80m respectively.
• The company is currently undertaking on ground work, with results expected in 4 to 6 weeks.

The expansion follows the company’s announcement on 9 June 2026 that it exercised its option to acquire the Quinn Fluorspar Project, located approximately 220km north of Las Vegas, Nevada.

According to the announcement, the newly staked claims were identified through a review of historic geological information from sources including the United States Geological Survey, the Nevada Bureau of Mines and Geology and Union Carbide Corporation, with the announcement stating that the historic observations have not yet been followed up with Company work.

The announcement provides detailed information on the Blue Bell Project, where historic United States Geological Survey sampling included one assay returning 88.9% CaF₂.

An adjoining breccia/stockwork zone mapped over at least 12m in width returned historic assays of 23.1%, 20.6% and 17.5% CaF₂.

The announcement also states there is no record of previous drilling at Blue Bell, where company representatives have recently visited the project with samples pending assay, while additional mapping and channel sampling are planned ahead of finalising a drill plan.

The Bonanza Project includes historic geological mapping completed by Union Carbide Corporation identifying two CaF₂ bearing breccia bodies extending more than 200m and 80m respectively, covering a combined target area of approximately 3,300m², together with three additional zones identified as “high grade” by Union Carbide Corporation.

The announcement states the host rock is a heavily silicified limestone or quartzite, while company representatives have also visited Bonanza with samples pending assay, and the project will be remapped and sampled in upcoming programs.

The expanded Quinn Fluorspar Project comprises seven project areas containing 20 recorded historic fluorspar occurrences.

According to the company’s priority table, Mammoth, Horseshoe and Big Jim are classified as P1 Drill Design targets, while Blue Bell and Bonanza are classified as P2 targets for locating, mapping and sampling, and El Cortez and Bruno require further work to assess their potential.

OD6 Managing Director Brett Hazelden commented:

“We have successfully consolidated Quinn Fluorspar into a district play and we believe this represents the most compelling emerging fluorspar project in North America. We’ve already identified three targets with genuine scale that warrant drilling to resource status: Horseshoe, Mammoth, and Big Jim. What makes this story even more meaningful is the addition of other occurrences including Blue Bell and Bonanza, two close proximity historic fluorspar deposits that show real scale potential. Together, these give us the ability to build a strong pipeline of exploration targets. The vision we’re working toward is a hub and spoke model, multiple feeds supplying a single processing facility at the Quinn Project.”

The announcement states that the Quinn Fluorspar deposits are part of the Great Basin (Basin and Range) of Nevada and are hosted in Paleozoic sediments including the Pogonip Limestone Formation and the Simonson Dolomite.

It states that fluorspar is deposited in epithermal breccias, veins and as replacement deposits parallel to the bedding in the limestone.

The announcement also notes that the United States is currently 100% reliant on imports of fluorspar and that fluorspar is listed on the United States Critical Minerals list.

The company is currently undertaking on ground work and will be assessing these projects, with results expected in 4 to 6 weeks.

The announcement also states that ongoing mapping and sampling will be undertaken ahead of drill permitting and planning.
