OD6 Metals Reports Ultra-High-Grade Fluorspar Intercepts at Horseshoe Prospect

• Ultra-high-grade fluorspar channel samples from Horseshoe Prospect.
• Strong continuity and potential for DSO and AcidSpar quality product.
• Advancing exploration and permitting for future drilling.

OD6 Metals (ASX: OD6) has reported ultra-high-grade channel sampling results from its Horseshoe prospect at the Quinn fluorspar project in Nevada.

The company reported multiple thick, continuous channel intercepts, confirming extensive breccia/replacement-hosted fluorspar mineralisation.

Key results include a 12 metre section averaging 68.9% CaF2, with a peak grade of 79.7% CaF2, with other significant intercepts of 7 metres averaging 73.1% CaF2, peaking at 82.0% CaF2 and a 2 metre channel that returned an average of 75% CaF2, with a peak of 79.9% CaF2.

The mineralisation remains open along strike and at depth, with only a portion of the mapped system tested to date.

These high grades are stated to be within metallurgical-grade fluorspar ranges, supporting the potential for Direct Shipping Ore (DSO) as MetSpar, as well as conventional upgrading to AcidSpar quality, which typically requires more than 97% CaF2.

Mammoth Prospect Context

The positive results at Horseshoe complement recent high-grade assays from the Mammoth Prospect within the Quinn project.

Previous due diligence channel sampling at Mammoth in April 2026 yielded continuous fluorspar mineralisation of 12 metres at 40.8% CaF2, including a peak of 54.0% CaF2 over 1 metre.

Prior to this, initial rock chip assays reported from the Mammoth Prospect in April 2026 confirmed high-grade fluorspar, with results up to 53.2% CaF2.

These results, alongside those from Horseshoe, reinforce the potential for a larger, district-scale high-grade fluorspar system extending at depth and along strike.

Broader Quinn Project Exploration

The company commenced its first modern systematic exploration program at the Quinn Fluorspar Project in March 2026, following approximately 60 years of limited activity.

Earlier remote sensing work utilising satellite and airborne hyperspectral analysis identified an 8 kilometre epithermal alteration corridor stretching from Dress Circle to Mammoth, and a 1.1 kilometre high-intensity alteration corridor linking the Horseshoe to Jumbo prospects.

This provides further evidence that known high-grade fluorspar occurrences are part of a larger continuous mineralised system.

The ongoing field work includes systematic soil and stream sediment sampling, detailed geological and structural mapping, and additional channel sampling across known deposits and newly identified alteration systems.

Development and Regulatory Outlook

The high grades at Horseshoe could support potential eligibility for Fast 41 Status, a US permitting accelerator.

If achieved, this could shorten the timelines towards drilling and early production plans for the project.

Historic small-scale mining at the Horseshoe Prospect previously produced approximately 26,000 tonnes.

The company is actively working to initiate permitting for maiden drilling through the US Forest Service.

“We are now focused on expanding sampling, refining geological controls, advancing towards drill targeting, and looking at options for bulk metallurgical samples,” managing director Brett Hazelden said.
