Key Highlights

  • OD6 Metals has agreed to acquire 20 unpatented lode claims covering the historic Rainbow and Nyco fluorspar mines in Nye County, Nevada.
  • Upon completion, the company's Quinn landholding would total 257 claims covering about 2,135 hectares across eight project areas.
  • Rock chip samples from the Rainbow and Bruno area returned results of up to 99.9% CaF2, although these are selective samples.
  • Consideration is US$89,166 in cash plus 480,000 fully paid shares, with completion expected in the coming weeks.

OD6 Metals Limited (ASX:OD6) has agreed to acquire 20 unpatented lode Mining claims covering the historic Rainbow and Nyco fluorspar mines in Nye County, Nevada, according to an announcement dated 12 November 2026. The Acquisition is designed to complete the company's consolidation of the Quinn Fluorspar District, which would bring its landholding to 257 mining claims across eight project areas. Completion is subject to customary conditions and is expected in the coming weeks. The deal also adds a vein-hosted style of target to a district that the company has previously described in terms of bulk-tonnage zones.

The historic Rainbow and Nyco mines

The Rainbow mine sits on land administered by the Bureau of Land Management and has a recorded production history stretching back to the 1940s. Published records cited by the company describe around 200 tonnes of high-grade fluorspar shipped from Rainbow and an adjacent claim in 1945 and 1946, the first fluorspar production in the district. Historic workings are said to extend across an 850-metre strike length, and the company's field visit confirmed that they are present.

The Nyco mine lies about 14 kilometres west-southwest of the company's Horseshoe prospect. Published historical records estimate roughly 1,100 tonnes of production at 50 percent CaF2, with an upper adit of about 122 metres and a second adit 21 metres in length. The company has not visited Nyco, and it stresses that these production and grade figures come from historical records compiled by third parties rather than verified data.

Sampling results and their limits

OD6's recent rock chip sampling at Rainbow returned 89.6% CaF2 from a 1-metre shear vein carrying purple and green fluorspar, along with 53.6% and 7.2% from altered volcanic country rock that flanks the main structure. At the adjacent Red Bluff prospect, samples returned 99.9%, 80.4% and 58.4% CaF2. The Bruno prospect returned 97.2% and 92.1%. The 99.9% result was adjusted by the company, which said a raw fluorine assay implied a value above 100 percent and therefore applied a top cut to 99.9%.

The company also notes that rock chip samples are selective by nature and do not represent true widths or continuity. No drilling has been completed at Rainbow, Bruno or Nyco, and the historical information has not been prepared in accordance with the JORC Code. Those points matter because the high-grade results could reflect selective sampling rather than the grade of the broader system.

Deal terms, permitting and open questions

The consideration comprises US$89,166 in cash, about A$127,500, paid from existing working capital, and 480,000 fully paid OD6 shares issued within the company's Placement capacity. The shares carry a voluntary 12-month escrow. No royalty, deferred or contingent consideration is payable, and the agreement can be terminated by either party if conditions are not satisfied by 31 December 2026.

Permitting is a relevant variable. The Rainbow and Bruno area sits primarily on BLM land, where the company says the pathway to ground-disturbing work is relatively rapid. Other Quinn projects sit on federal forest land and require permitting through the US Forest Service before drilling. The company also notes that the United States imports all of the fluorspar it consumes, which is the basis for its critical minerals positioning, but it has not quantified the cost or timetable to bring any of these projects into production.

Final Word

OD6's Nevada acquisition extends its control of the Quinn district and introduces narrow, vein-hosted targets beside the bulk-tonnage zones at Horseshoe and Mammoth. The rock chip results are high, but they are selective and have not been replicated by drilling. Whether the Rainbow and Nyco structures can be developed into a meaningful resource will depend on the trenching and drilling program that follows completion, and on the permitting that governs access to those sites.
