Highlights

  • Evion Group has signed a binding option and joint venture agreement to earn a majority interest in the Blue Nose property, adjoining its Carp Fluorspar Project in Nevada.
  • Stored drill samples from historical limestone drilling at Blue Nose have never been assayed for fluorine, offering a low-cost initial test of the ground.
  • The transaction is subject to Due Diligence and consents, with staged cash and share consideration payable over a multi-year period.

Fluorspar has gained prominence on critical minerals lists in the United States and elsewhere, reflecting its role in steelmaking, aluminium production, refrigerants and battery materials. That theme has given US-focused projects a higher profile within the broader universe of Metal and Mining Stocks on the ASX. Evion Group NL (ASX:EVG), a critical minerals company with graphite interests in Madagascar and India, has now secured an option to earn into the Blue Nose property in Nevada. The ground sits immediately northwest of Evion’s Carp Fluorspar Project, and the company says the pair originally formed a combined claim block. The deal is drawing attention because it consolidates a historic fluorspar district under a single operator and comes with a large inventory of stored drill samples that can be re-tested without new drilling.

Blue Nose Option and Joint Venture Terms

According to Evion’s announcement to the ASX, its US Subsidiary has signed a Property Option and Joint Venture Agreement with Reno-based Infrastructure Materials Corp. Over the Blue Nose property in Lincoln County, Nevada, within the Viola Mining District. The property comprises unpatented lode claims on Bureau of Land Management land.

Evion can earn up to a majority interest in non-reserved minerals, including fluorspar, silver, gold and copper. Infrastructure Materials retains a minority interest in those minerals and keeps full rights to reserved minerals, namely marble and industrial limestone products. In return, Infrastructure Materials can earn a minority interest in the Carp claim group, free carried through to a bankable feasibility study.

Consideration comprises staged cash payments and Evion shares over a multi-year period, plus a due diligence payment. There is no minimum expenditure requirement, Evion will act as operator, and completion is subject to due diligence, regulatory and external consents, and no material adverse change.

Stored Samples Offer a Low-Cost Starting Point

Infrastructure Materials previously drilled reverse circulation holes across Blue Nose targeting limestone. Duplicate sample splits from that work are stored in Reno, and Evion says they were analysed for a range of oxides, including barium oxide, but never for fluorine.

Evion plans to inventory the material and re-analyse selected samples for fluorine, while screening existing barium oxide data as a possible pathfinder for barite and fluorite. Managing Director David Round said Blue Nose and Carp started life as a combined claim block, with the historic Carp pit on its southeast corner, and described the stored material as a fast, low-cost way to test the ground before committing to new drilling.

Building on the Carp Fluorspar Project

Carp hosts a historic open pit that produced fluorspar over several years during the last century, with the material supplied to Kaiser Steel. That production history confirms that fluorspar mineralisation in the district was mined on a commercial basis. Evion has reported high-grade calcium fluoride results from recent surface sampling, and on the day after the Blue Nose announcement it reported that a drone magnetic survey at Carp had been completed.

The company is also evaluating whether to extend the drone magnetic survey and surface geochemistry from Carp across Blue Nose, and expects to receive Infrastructure Materials’ drill database and records as part of the transaction. Work at Carp is continuing in parallel, so the company can advance its existing project while it assesses the newly optioned ground.

Strategic Fit Within Evion’s Portfolio

Beyond Nevada, Evion holds the Maniry Graphite Project in Madagascar and an equal-share interest in Panthera Graphite Technologies in India. The Blue Nose option adds scale to its US critical minerals footprint, where fluorspar has attracted policy attention as governments seek to diversify Supply chains.

Risks and Challenges

The transaction remains conditional, and Evion’s interest depends on meeting staged payment obligations. Re-assaying historical samples may or may not identify meaningful fluorine, and any results would be exploration information rather than a mineral resource. Converting historical production and surface sampling into a defined resource will require further drilling, metallurgical work and permitting.

As a junior explorer, Evion also faces funding needs across multiple projects, and the market for fluorspar and graphite can be affected by pricing, trade policy and competition from established suppliers.

Consolidating a Historic Nevada District

The Blue Nose option gives Evion Group (ASX:EVG) the chance to consolidate ground surrounding the historic Carp fluorspar pit and to test stored drill samples at relatively low cost. Outcomes will depend on due diligence, re-assay results and subsequent exploration. The deal reflects broader interest among ASX-listed explorers in US critical minerals projects, a theme that continues to shape activity across the Australian resources sector.
