• Channel sampling at Blue Bell returned maximum calcium fluoride grades of 99.5 per cent, with averages of 51.1 per cent over 24 metres in one channel.
  • Rock chip results reached 98.4 per cent CaF2, although rock chips are selective samples.
  • No drilling has been reported at Blue Bell, and the release does not report a Mineral Resource or Exploration Target.

OD6 Metals Limited (ASX:OD6) has reported its first exploration results from Blue Bell, a fluorspar target within the Quinn Fluorspar Project in Nevada, USA. Channel sampling and rock chip sampling returned high calcium fluoride (CaF2) grades at surface, and the company has identified Blue Bell as the fourth priority target in the project. The results are surface samples only, and no drilling has been reported at Blue Bell.

Project and tenure

Blue Bell lies about 12 kilometres south of the Horseshoe prospect. OD6 holds 100 per cent of 226 Nevada Mining claims covering about 1,890 hectares, staked in 2025 and 2026, with the claim expansion announced on 23 June 2026. The claims are on federal National Forest land outside designated Wilderness Study Areas. A 2 per cent net smelter return Royalty applies to Horseshoe, Mammoth and Bonanza but not to Blue Bell, and state royalties apply. The project includes more than 20 known fluorspar occurrences and an 8 kilometre mineralised corridor.

Sampling results

Three channels were cut across the prospect. Bluebell_Front1 averaged 51.1 per cent CaF2 over 24 metres, with a maximum of 83.4 per cent. Bluebell_Back2 averaged 29.2 per cent over 28 metres, including 8 metres at 50.7 per cent from 18 metres, with a maximum of 87.3 per cent. Bluebell_Back1 averaged 39.7 per cent over 12 metres, including 7 metres at 60.2 per cent from 5 metres, with a maximum of 99.5 per cent.

The highest rock chip results were 98.4 per cent CaF2 from green fluorspar, 96.0 per cent from footwall stockwork veins and 95.6 per cent from two fluorspar veins, while lower values ranged from 5.1 to 49.3 per cent. The company notes that rock chips are selective samples. The main high-grade vein is 20 centimetres to 2 metres wide and exposed for about 40 metres above a small historic quarry. The wider mineralised zone is mapped at roughly 70 by 100 metres and remains open in several directions, including east under talus cover, with results to the west still pending. OD6 states that channel sample widths are not true widths.

Processing potential and caveats

A large-format sample collected for metallurgical and ore-sorting testwork returned 91.6 per cent CaF2, as previously announced on 12 August 2026. OD6 says the low-impurity mineralisation may support premium Acidspar (more than 97 per cent CaF2) and Metspar products after beneficiation, and proposes a hub-and-spoke model in which satellite deposits feed a central processing facility, subject to further work. Those are company aspirations and have not been demonstrated.

Samples were prepared by ALS in Reno and re-assayed in Perth using the F-XRF24 method, with CaF2 calculated from fluorine results. The release does not report a Mineral Resource or Exploration Target, and these surface results do not indicate tonnage.

Permitting and next steps

Drill access is being permitted through the US Forest Service. OD6 proposes drilling and bulk sampling at Horseshoe and Mammoth in early 2027, subject to permitting. At Blue Bell, the next steps are to complete the geological interpretation, follow-up mapping and sampling, and assessment of extensions. The company also plans metallurgical testwork on beneficiation and the Metspar and Acidspar pathways, environmental and cultural studies for future drilling, and continued evaluation of the known occurrences across the expanded claim package. It also notes gold upside identified in soil sampling at Mammoth, Horseshoe and Dress Circle.

OD6 also holds the Splinter Rock Rare Earth Project in Western Australia and the Gulf Creek Copper-Zinc Project in New South Wales. The Competent Person for the release is Dr Darren Holden of GeoSpy Pty Ltd. Because Blue Bell has not been drilled and the sampling is selective, the results show the presence of high-grade fluorspar at surface but not its scale or continuity.
