Highlights
- A CSAMT geophysical survey at Lirios 1 identified two priority drill targets.
- A large low-resistivity anomaly located about 500 metres southeast of existing drilling remains open in multiple directions and is considered a priority target.
- The survey delineated a deep-rooted anomaly adjacent to current drilling that is interpreted as a potential feeder conduit for mineralising fluids.
- The survey identified sub-parallel vertical features parallel to the San Elias and San Miguel feeder systems, providing significant targeting vectors.
- Ground verification work is underway to support Phase 2 drilling and advance plans for a maiden JORC Mineral Resource Estimate at Los Lirios.
EV Resources Ltd (ASX:EVR) shares traded higher on Wednesday after the company announced new exploration targets and expanded scale potential at the Lirios 1 prospect within its Los Lirios Antimony Project in Oaxaca, Mexico. The company has completed and interpreted a 2D inversion model from a Controlled Source Audio-frequency Magneto-Telluric (CSAMT) geophysical survey at the prospect. The survey revealed multiple new exploration targets, including a potential feeder zone, a large untested anomaly, and a project-wide structural network that could play a key role in controlling mineralisation.
Geophysical Survey Expands Exploration Footprint
The CSAMT survey was designed to map subsurface conductivity changes across a vertical window of approximately 500 metres to identify hidden sulphide accumulations and feeder structures to establish a potential geophysical fingerprint of mineralisation. The program, covering five survey lines spaced 100 metres apart, was processed by Zonge International and interpreted by SouthernRock Geophysics.

Results indicate that the hydrothermal system extends beyond the area tested during Phase 1 drilling, outlined two priority target zones and established a vectoring tool that may assist in locating mineralised feeder systems.
EVR shares were trading at AUD 0.007 per share, up over 7%, at the time of writing on 10 June 2026.
