OD6 Metals (ASX: OD6) — Rediscovers Historic Big Jim Fluorspar Lode at Quinn Project in Nevada With Reported Grades Up to 98.6% CaF₂
On 12 May 2026, OD6 Metals Limited (ASX: OD6) announced the rediscovery of the historically referenced Big Jim Fluorspar Lode at its Quinn Fluorspar Project in Nevada, approximately 220 km north of Las Vegas. Through targeted field reconnaissance guided by 1940s US Geological Survey reports, the company located the Big Jim workings, confirming massive fluorspar exposed at surface with a historically reported grade of 98.6% CaF₂ from the main lode and 60% CaF₂ from footwall breccia material. Historic workings have been mapped over more than 220 metres (700 feet) with reported high-grade fluorspar throughout, open to the north and south. The company has collected multiple rock samples (assays pending) and metallurgical samples (testwork underway). Big Jim represents a third extensive fluorspar system on the Quinn Project, complementing the previously identified Mammoth and Horseshoe deposits. No drilling has been conducted at Big Jim, and the company states that visual estimates are no substitute for laboratory results.

Big Jim Fluorspar Lode — History and 2026 Field Confirmation
Big Jim was discovered and intermittently exploited by Frank and Joe "Big Jim" Perkins from 1934. A 1947 report by Goulet and Jones documented the Big Jim lode as a shallow-dipping, high-grade fluorspar vein approximately 2 metres (6 feet) in width. Historic assay results from the vein include 94.6%, 96%, and 98.6% CaF₂. Footwall breccia material — historically described as "gangue" and considered uneconomic in the 1940s — returned up to 60% CaF₂. The company notes that modern fluorspar projects generally consider grades above 20% CaF₂ economic, with some companies suggesting grades above 8% CaF₂ may be viable.
OD6's 2026 field team confirmed the location of the Big Jim workings by identifying the "Big Rock" surface landmark referenced in the 1947 report and geographically referencing the historic mine sketch map. Surface observations are described as consistent with historic reports. The company visually estimates the main lode at approximately 85–95% CaF₂ over approximately 2 metres width, with the footwall breccia estimated at 40–60% CaF₂ over at least 2 metres (lower contact not observed, so true width may be greater).
The main lode is hosted in limestone beneath a jasperoidal (silica-rich) lithocap, with fluorspar occurring as replacement deposits and vein/breccia systems. A second lode ("Rocket") was observed in a small pit at approximately 1 metre width, and a third lode approximately 20 metres beneath is referenced in historic reports but has not been observed in the field.
All results presented are historic in nature. The company has collected new rock samples, which have been sent to ALS Global in Reno, Nevada, with assays pending. Visual estimates are explicitly disclaimed by the company as no substitute for laboratory results.
Quinn Fluorspar Project — Three Deposit Systems
Big Jim is the third extensive fluorspar system identified on the Quinn Project, complementing:
Mammoth: High-grade fluorspar mineralisation (>40% CaF₂) in replacement/breccia style, mapped over a ~9,000m² area.
Horseshoe: High-grade fluorspar mineralisation (>40% CaF₂) in replacement/breccia style, mapped over a ~3,000m² area, located approximately 1 km south-southwest of Big Jim.
Historic rock chip results across the broader Quinn project area include grades up to 94% CaF₂. All three systems are at the surface mapping and sampling stage with no drilling conducted.
About OD6 Metals — Diversified Critical Minerals Explorer
OD6 Metals is an Australian company with exploration and development projects across rare earths, fluorspar, and copper:
Splinter Rock Rare Earths (Western Australia): 100%-owned clay-hosted REE deposit with an Indicated Resource of 119Mt at 1,632 ppm TREO and an Inferred Resource of 563Mt at 1,275 ppm TREO (~23% magnetic rare earths). Heap leach flowsheet has achieved ~75% Nd and Pr recovery.
Quinn Fluorspar (Nevada, USA): Option agreement to acquire the project, announced 4 March 2026. Located on Federal Land (National Forest) outside designated Wilderness Study Areas. A 2% NSR applies on future production. Drilling requires US Forest Service permitting.
Gulf Creek Copper-Zinc (NSW, Australia): Historic high-grade copper mine (2–6.5% Cu) with 2025 maiden drilling and >3 km of strike identified.
Market Context
OD6 closed at $0.190 on the announcement day, up +15.2% from a previous close of $0.165, with an intraday high of $0.205. The 52-week range spans $0.020 to $0.233. The announcement comes amid heightened interest in U.S.-based fluorspar projects, with the United States 100% import-reliant on fluorspar and the mineral designated as a U.S. Critical Mineral with applications in semiconductor manufacturing, battery technologies, nuclear fuel, and defence.
Risks & Considerations
All results are historic: The assay grades reported (up to 98.6% CaF₂) are from 1940s-era reports using wet chemistry techniques (likely the Bidtel technique). While the Competent Person considers the data adequate for context, the company cannot independently attest to the nature or accuracy of the historic work. New assay results from OD6's 2026 sampling are pending.
Visual estimates are not assay results: The 2026 field observations include visual grade estimates (85–95% CaF₂ for the main lode, 40–60% for the breccia). The company explicitly disclaims these as no substitute for laboratory results.
No drilling: No drilling has been conducted at Big Jim, Mammoth, or Horseshoe. All three systems remain at the surface mapping and sampling stage. Drilling requires permitting through the US Forest Service.
Option agreement, not ownership: OD6 holds an option to acquire the Quinn Project (announced 4 March 2026). The transaction has not completed. A 2% NSR royalty applies on future production.
No Mineral Resource: No Mineral Resource or economic study exists for any fluorspar target within the Quinn Project. The size, geometry, and grade distribution of the Big Jim system at depth are unknown.
Single-lode width from historic reports: The main lode is reported at approximately 2 metres width from 1940s observations. The footwall breccia lower contact was not observed, meaning the total mineralised width is uncertain. A third lode referenced in historic reports has not been located.
Federal land permitting: The project is located on National Forest land. While outside Wilderness Study Areas, permitting for drilling and future development activities is subject to US Forest Service approval processes.
