Lodestar Minerals Limited (ASX:LSR) attracted market attention on 12 May 2026 after the company released a new exploration update from its Virgin Mountain Heavy Rare Earth Element (HREE) Project in the United States, while also entering a Trading halt pending a separate announcement linked to assay results from the Ned’s Creek project.

The company’s shares last traded at AUD 0.020 on 11 May 2026 before the trading halt took effect. The halt will remain in place until the earlier of the commencement of trading on 14 May 2026 or the release of the pending market announcement.

The latest exploration update centred on the Virgin Mountain Project, where Lodestar confirmed continuity of xenotime-bearing rare earth element mineralisation along a mapped structural trend. The company described the findings as an important development in understanding the scale and geological characteristics of the project.

With investor interest in critical minerals and heavy rare earth Supply chains continuing globally, the update placed additional focus on Lodestar’s US-based exploration activities, particularly given xenotime’s association with high-value heavy rare earth elements.

Virgin Mountain Exploration Confirms Surface Mineralisation Trend

According to Lodestar, field activities at the Virgin Mountain Project were recently completed by its US exploration team, which included Exploration Manager Finn Hunter alongside specialist consultants Robin Wilson and Dr Ross Chandler.

The field program confirmed surface continuity of xenotime-bearing rare earth mineralisation across the interpreted structural trend at the project. The company noted that xenotime is a rare-earth phosphate mineral commonly associated with heavy rare earth elements such as yttrium, dysprosium, terbium, erbium, ytterbium and lutetium.

Heavy rare earth elements typically attract elevated strategic interest because of comparatively constrained global supply conditions and their importance in advanced technologies and industrial applications.

Lodestar stated that the observed mineralisation supports the interpretation of Virgin Mountain as a metasomatic-style rare earth element system, a deposit style often associated with structurally controlled mineralisation hosted within Proterozoic basement rocks.

Management indicated that the continuity of mineralisation observed at surface represented a favourable step in advancing the project toward more detailed target definition.

Geological Comparisons Draw Interest

One of the more notable aspects of the update was Lodestar’s reference to geological similarities between Virgin Mountain and the Music Valley Rare Earth Element Project in California.

The company stated that field observations identified characteristics comparable to those seen at Music Valley, which is owned by Dateline Resources Limited.

However, Lodestar also included a cautionary statement clarifying that the comparison remains conceptual in nature. The company emphasised there is no certainty that mineralisation at Virgin Mountain will match Music Valley in terms of scale, grade or economic outcomes.

Even so, the comparison highlighted geological traits that may assist the company in refining its exploration model as additional work progresses across the project area.

The field observations were undertaken directly on-site and incorporated geological mapping and structural interpretation work aimed at understanding the extent of the mineralised corridor.

Next Phase to Focus on Drill-Ready Targets

Following the latest field program, Lodestar outlined plans to advance exploration activities through airborne Geophysical surveys designed to improve structural targeting across the broader project area.

The company intends to undertake high-resolution airborne radiometric and magnetic surveys covering the 5km structural corridor identified at Virgin Mountain.

According to Lodestar, the surveys are expected to improve interpretation of the project’s structural architecture and help delineate the extent of the mineralised shear system at surface.

The company plans to integrate the airborne dataset with existing outcrop mapping and ground-based radiometric work to prioritise drill-ready targets for future exploration campaigns.

Management indicated that the next phase of work is focused on accelerating target generation while improving geological understanding of the HREE-bearing structures identified during field activities.

The company’s exploration strategy appears centred on systematically refining targets before moving into more advanced drilling programs.

CEO Highlights Exploration Potential

Lodestar CEO and Executive Director Coraline Blaud commented that the company’s US exploration team had successfully confirmed continuity of the metasomatic-style trend hosting heavy rare earth mineralisation at Virgin Mountain.

Management noted that the project continues to demonstrate exploration potential as the company advances toward the next stage of work.

The exploration team involved in the field activities included three rare earth specialist geologists, reflecting the company’s focus on technical evaluation of the emerging heavy rare earth opportunity.

The latest update also reinforces Lodestar’s broader positioning within the critical minerals exploration sector, particularly across commodities linked to energy transition and advanced Manufacturing supply chains.

Trading Halt Linked to Ned’s Creek Assay Results

Alongside the Virgin Mountain announcement, Lodestar separately requested a trading halt from the ASX effective from the commencement of trading on 12 May 2026.

The company stated that the halt was requested pending an announcement regarding assay results from its Ned’s Creek project in Western Australia.

According to the request lodged with ASX, Lodestar expects the trading halt to remain in place until either an announcement is released or normal trading resumes on 14 May 2026.

The company also advised that it was not aware of any reason why the halt should not be granted and confirmed no additional information was necessary to inform the market at this stage.

Trading halts are commonly used by ASX-listed companies when preparing potentially market-sensitive announcements, allowing information to be released in an orderly manner.

The pending assay results from Ned’s Creek now add another area of investor focus beyond the company’s US rare earth activities.

Lodestar’s Broader Project Portfolio

Beyond Virgin Mountain, Lodestar Minerals maintains a diversified exploration portfolio spanning critical minerals, gold and base metals projects across multiple jurisdictions.

The company’s project base includes the Los Loros Porphyry copper-molybdenum-gold project and the Three Saints IOCG project in Chile.

In Australia, Lodestar holds the Ned’s Creek Gold Project and the Earaheedy Project in Western Australia.

The company also retains exposure to lithium through performance rights associated with ORE Resources, which owns the Kangaroo Hills and Miriam Projects in Western Australia.

The Virgin Mountain Project adds a United States-based heavy rare earth element opportunity to the broader portfolio, aligning the company with increasing exploration interest in non-Chinese rare earth supply chains.

Market Attention on Heavy Rare Earth Potential

The latest Virgin Mountain update appears to have increased attention on Lodestar’s exposure to heavy rare earth elements, particularly given the identification of xenotime-bearing mineralisation across the mapped structural trend.

The company’s planned airborne geophysical work is expected to play a key role in refining exploration targets and determining the scale of the mineralised corridor.

Meanwhile, the ASX trading halt linked to Ned’s Creek assay results has introduced an additional near-term catalyst for the company.

With exploration activities advancing across multiple projects, investors are likely to monitor both the upcoming Ned’s Creek announcement and future developments from Virgin Mountain as Lodestar progresses toward drill targeting and further technical evaluation.
