OD6 Metals Advances US Fluorspar Play with Ultra-High Grades and Strategic Advisor Appointment

Quinn Fluorspar Acquisition Positions OD6 at US Critical Minerals Frontline

OD6 Metals (ASX:OD6) has taken a decisive step into the US critical minerals arena by securing an exclusive option over the Quinn Fluorspar Project in Nevada, a district-scale asset boasting ultra-high-grade fluorspar mineralisation. The project covers approximately 400 hectares across 48 state mining claims, with rock and channel samples revealing grades as high as 94% CaF2 and continuous channel widths exceeding 12 metres at over 40% CaF2.

Located in Nevada, ranked the world's top mining jurisdiction, Quinn taps into a US market wholly reliant on imports for fluorspar, a mineral critical to semiconductor manufacturing, aerospace, and defence. OD6’s acquisition terms limit upfront risk with milestone payments tied to drilling approvals, resource declaration, and commercial production, alongside royalties on extracted minerals.

Systematic exploration commenced in April, marking the first modern program at Quinn in six decades. Initial channel sampling at Mammoth and Horseshoe prospects has validated historic data, confirming extensive high-grade continuity. Notably, channel samples at Horseshoe returned spectacular results including 12 metres at 68.9% CaF2 and peak values surpassing 79%, reinforcing potential for direct shipping ore and acid-grade fluorspar production. These findings echo the recent detailed assays from the project’s ultra-high-grade zones, underscoring the scale and quality of mineralisation discovered OD6 Metals Confirms Ultra-High-Grade Fluorspar Up to 82% CaF2 at Horseshoe Prospect, Nevada.

Metallurgical Advances at Splinter Rock Rare Earths

In Western Australia, OD6 is progressing its Splinter Rock Rare Earth Project with advanced metallurgical testwork underway at ANSTO. The program targets heap leach optimisation, impurity removal, and the production of commercially relevant mixed rare earth carbonate and hydroxide products. These efforts aim to de-risk processing pathways and support offtake negotiations, crucial for financing and future development.

OD6’s participation in the Australian Critical Minerals Strategic Reserve framework signals its commitment to fostering supply chain resilience and market certainty for rare earth elements. The company’s resource base at Splinter Rock remains one of Australia’s largest clay-hosted rare earth deposits, with a recent resource estimate confirming significant high-value magnetic rare earth content.

New Copper Targets Emerge at Gulf Creek, NSW

At the Gulf Creek Copper Project in New South Wales, Downhole Electromagnetic (DHEM) surveys have identified strong off-hole conductors beyond recent drill holes, suggesting potential fault offsets or stacked mineralised lodes undetected by historic drilling. These conductors lie near historic high-grade copper workings, presenting compelling new drill targets as OD6 applies modern geophysical techniques to a century-old mine site.

While some DHEM targets require further geological evaluation before testing, the identification of these conductors expands the exploration upside across the project’s >3km strike length, complementing the company’s broader critical minerals strategy.

Capital Raising and Strategic Advisory Strengthen Corporate Position

To fund its aggressive exploration and acquisition strategy, OD6 completed a two-tranche placement raising A$3.4 million at $0.05 per share, with the second tranche pending shareholder approval. The company ended the quarter with a cash balance of A$3.48 million, supplemented by a recent A$216k R&D tax offset refund.

Significantly, OD6 appointed The Hon Julie Bishop as Strategic Advisor to enhance engagement with Australian and US government stakeholders on critical minerals policy and supply chain initiatives. Bishop’s extensive international relations experience is expected to bolster OD6’s positioning amid growing geopolitical focus on critical mineral supply security.

OD6’s Managing Director Brett Hazelden described the quarter as transformational, highlighting the strategic intersection of critical mineral supply security and US supply chain re-shoring themes underpinning the Quinn acquisition and broader company initiatives.
