GRAFTON RESOURCES STARTS HELIBORNE MOBILE MT GEOPHYSICAL SURVEY AT ALICAHUE GOLD-COPPER PROJECT, CHILE

Expert Geophysics Surveys Inc. has started a planned 80-line-kilometre mobile magnetotelluric (MobileMT) helicopter-borne survey at the Alicahue gold-copper project in Valparaiso, Chile. This survey will cover the entirety of Grafton's Alicahue gold-copper project within one day and interpreted results are expected in March, 2026.

MobileMT is a leading geophysical technology, which aids in the identification of subsurface geologic structures, alteration halos and contrasting lithologies. Complementary VLF-EM (very-low-frequency/electromagnetic) data, which provides near-surface electromagnetic (EM) information, should yield increased resolution of shallow features. Combining the methods should identify deep-seated faults, lithological contacts and structures controlling mineral systems from surface to a depth of approximately one kilometre to two kilometres, dependent on the conductivity distribution of the local geology.

Campbell Smyth, chairman of the company, commented: "We expect the MobileMT data will provide a three-dimensional image of the Alicahue project area. We hope the survey will assist us in tracing the outline of a possible porphyry centre in the southeast concession. Further we hope the survey helps us to vector towards the origin of the IOCG vein systems and possible feeder zones to gold and copper vein mineralization mapped in the area. MobileMT is known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres and resistive bodies representative of intrusions."
