Quinn Fluorspar Exploration Revived After 60 Years—Can OD6 Deliver New Discoveries?

A New Chapter for Quinn Fluorspar

OD6 Metals has embarked on a landmark exploration campaign at the Quinn Fluorspar Project in Nevada, marking the first systematic fieldwork at the site in approximately 60 years. This initiative signals a renewed focus on a region historically known for its ultra high-grade fluorspar mineralisation, with grades exceeding 40% calcium fluoride (CaF2) in key deposits.

The project, located roughly 220 kilometres north of Las Vegas, holds strategic significance given the United States’ complete reliance on imported fluorspar, a critical mineral essential for sectors ranging from battery technology to aerospace and defence. OD6’s exploration program is designed to build a comprehensive geochemical and geological framework that could underpin future resource development.

Targeting High-Grade Deposits and New Zones

The initial phase involves collecting around 320 soil samples across known high-grade deposits such as the Horseshoe and Mammoth sites, as well as the recently identified Horseshoe-Jumbo alteration corridor. These areas have historic records of significant fluorspar mineralisation, with the Mammoth Deposit previously returning channel samples of up to 10 metres at 44.7% CaF2.

Beyond these established targets, the program ambitiously explores two substantial and previously untested alteration systems: the 70,000 square metre Lithocap target and the expansive 700,000 square metre Dress Circle alteration zone. These zones could potentially host new fluorspar mineralisation, expanding the project’s resource base.

Building Towards Drilling and Development

Complementing soil sampling, OD6 is conducting regional stream sediment sampling across approximately 40 sites to detect upstream mineralised catchments. This multi-pronged approach aims to refine drill targets and support detailed geological mapping and channel sampling scheduled for April 2026.

Managing Director Brett Hazelden emphasised the significance of this exploration milestone, highlighting the scale of alteration and widespread high-grade occurrences as strong indicators of further discovery potential. The company is simultaneously advancing due diligence, compiling historic data, and preparing for permitting processes necessary for an eventual drilling campaign.

Strategic Importance and Market Context

Fluorspar’s critical role in manufacturing hydrofluoric acid, AI semiconductor etching, and nuclear fuel processing underscores the strategic value of domestic supply. With global fluorspar markets dominated by China, OD6’s efforts in Nevada could position the company as a key player in securing supply chains for the US and allied industries.

While initial assay results are awaited, the exploration program’s scope and systematic approach reflect a confident step forward in unlocking the Quinn Project’s potential. The coming months will be pivotal as assay data and mapping results shape the next phase of drilling and development planning.
