Evion Group NL (ASX:EVG) has completed a high-resolution drone magnetic survey at its Carp Fluorspar Project in the Viola Mining District of Lincoln County, Nevada, with processed data delivered to the company and interpretation now underway ahead of maiden drill programme planning.

Key Points

Drone magnetic survey completed across the entire project claim area of approximately 4.94km² at 25-metre line spacing, flown 20–25 metres above ground level
Processed data delivered as five magnetic products: Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), Tilt Derivative (TDR), and Analytical Signal (AS)
Initial review has added detail to previously interpreted structures and identified others not previously noted, which had been drawn largely from satellite imagery
Assay results from 41 rock chip samples are expected in two batches through November 2026, followed by a surface geochemical survey targeted for completion by end of 2026
Bureau of Land Management permitting preparation for a maiden drill programme is planned for early 2027

Drone Magnetic Survey Scope and Data Delivery

The survey, described by the company as the first component of the Phase Two exploration programme, was flown at 25-metre line spacing between 20 and 25 metres above ground level across the full claim area of approximately 4.94 square kilometres. The company said the dataset represents a materially higher-resolution magnetic dataset than has previously been available over the project. The processed data was delivered as five magnetic products, including TMI, 1VD, 2VD, TDR, and Analytical Signal, and the company stated the survey was delivered on the timetable set out at commencement.

Interpretation Integrating Magnetic, LiDAR and Orthophoto Datasets

Detailed interpretation is underway integrating the magnetic data with LiDAR and orthophoto datasets, with a focus on the regional northwest-southeast structural trend and the local north-south mineralised corridor. The company stated the initial review has added detail to previously interpreted geological structures and identified others not previously noted. The earlier structural interpretation at Carp had been drawn largely from satellite imagery. The company said interpretation results will be reported to the market once complete, and will also incorporate pending rock chip assays and the planned surface geochemical survey.

Carp Fluorspar Project Background and Next Steps

The Carp Fluorspar Project comprises 59 unpatented lode claims covering approximately 493 hectares on Bureau of Land Management administered land. The project has a documented production history, with approximately 44,900 tonnes at approximately 69% CaF2 mined and sold between 1958 and 1971 to Kaiser Steel Corporation as metallurgical-grade fluorspar without beneficiation. Next steps disclosed by the company include reporting assay results from 41 rock chip samples submitted in two batches through November 2026, completing the surface geochemical survey by end of 2026, and preparing for Bureau of Land Management permitting for a maiden drill programme in early 2027.
