OD6 Metals (ASX:OD6) reports high grade fluorspar results from Horseshoe Prospect
OD6 Metals has reported expanded channel sampling results from the Horseshoe Prospect within the Quinn Fluorspar Project in Nevada, USA, including 50m @ 63.9% CaF₂ from the SE Wall, which the Company reported as the thickest mineralised interval to date.
The sampling program was completed across exposed areas within the historic pit as part of the Company’s ongoing work at the project.
Highlights
Expanded channel sampling results from Horseshoe confirmed broad zones of continuous high grade fluorspar mineralisation from surface.
Results included 50m @ 63.9% CaF₂ from the SE Wall, 27m @ 54.4% CaF₂ from the North Pit, and 22m @ 70.7% CaF₂ from the NW Wall, including 9m @ 74.9% CaF₂, 8m @ 71.2% CaF₂ and 5m @ 62.4% CaF₂.
Central Bench channel sampling returned 15m @ 75.8% CaF₂.
All 118 channel samples averaged 64.4% CaF₂, with 84% of samples grading above 50% CaF₂ at an average of 70.7% CaF₂.
Channel sampling confirmed mineralised widths of 60m, with previous reported drilling and open pit exposure indicating a tabular zone 15 to 30m thick.
The Quinn Fluorspar Project is located approximately 220km north of Las Vegas, Nevada, with OD6 announcing the exercise of the option agreement to acquire the project on 9 June 2026, with completion remaining subject to shareholder approval at the General Meeting on 20 July 2026.
The project includes the Horseshoe and Mammoth Projects, where fluorspar mineralisation greater than 40% CaF₂ has been identified.
The Company has also identified other fluorspar occurrences across the wider project area, including historic rock chip results of up to 98.6% CaF₂.
The channel sampling program used chip channel samples collected from exposed areas within the historic pit. OD6 stated that the technique involves collecting representative samples using a hammer drill from 1m intervals along the side of the historic pit, with each sample representing a fixed width across the sampled interval.
The latest results covered the NW Wall, Central Bench, SE Wall and North Pit areas, with the Company reporting that mineralisation remains open up dip beneath the silicified cap and down dip beneath talus cover.
OD6 Managing Director Brett Hazelden commented on the latest results.
“These channel sampling results represent another outstanding outcome for OD6 and further validate the scale, exceptional grade, width and geological potential of the Horseshoe deposit within the Quinn Fluorspar Project.”
The Quinn Fluorspar deposits are located within the Great Basin region of Nevada and are hosted in Paleozoic sediments including the Pogonip Limestone Formation and the Simonson Dolomite.
OD6 stated that fluorspar is deposited in epithermal breccias, veins and as replacement deposits parallel to bedding in limestone.
The Company’s next steps include finalising the shareholder approval process and completion of the Quinn transaction, receiving pending assay results, completing geological modelling and drill targeting, integrating activities into permitting activities, lodging bulk sample permit applications, commencing metallurgical testwork programs and preparing a maiden drilling program.
OD6 Metals is continuing activities at the Quinn Fluorspar Project following the latest Horseshoe Prospect results.
The project work program remains focused on advancing geological modelling, permitting activities, metallurgical testwork programs and preparation of a maiden drilling program.
The Quinn Fluorspar Project transaction remains subject to shareholder approval, with Horseshoe, Mammoth and Big Jim identified as fluorspar prospects within the project.
