Grafton Resources Inc. has commenced an 80 line-kilometre mobile magnetotelluric heliborne survey at its Alicahue Gold-Copper Project in Valparaiso, Chile. The survey, conducted by Expert Geophysics Surveys Inc., will cover the entire project area within a single day, with interpreted results anticipated in March 2026.
The MobileMT technology represents a significant advancement in mineral exploration, capable of identifying subsurface geologic structures, alteration halos, and contrasting lithologies. When combined with complementary VLF-EM data that provides near-surface electromagnetic information, the survey is expected to yield increased resolution of shallow features. This integrated approach aims to identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to depths of approximately 1 to 2 kilometers, depending on the conductivity distribution of the local geology.
Campbell Smyth, Chairman of Grafton Resources, emphasized the survey's potential significance. "We expect the Mobile MT data will provide a three-dimensional image of the Alicahue Project area," Smyth stated. "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."
The importance of this survey lies in MobileMT's proven capability to identify areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres, as well as resistive bodies representative of intrusions. This technology has become increasingly valuable in modern mineral exploration for its ability to provide detailed subsurface imaging without extensive ground disturbance.
For investors and stakeholders following mineral exploration developments, the results of this survey could have substantial implications. Positive findings might indicate the presence of significant gold and copper mineralization, potentially increasing the project's valuation and attracting further investment. The mining industry closely watches such technological applications, as successful implementations can set precedents for exploration efficiency and effectiveness in similar geological settings worldwide.
The broader implications extend to Chile's mining sector, where advanced exploration techniques contribute to maintaining the country's position as a leading copper producer. Efficient identification of mineral resources supports responsible resource development while minimizing environmental impact through targeted exploration.

This survey represents a critical step in Grafton Resources' systematic exploration approach at Alicahue. The project's location in Chile's prolific mineral belts adds geological significance to the undertaking, as the region hosts numerous world-class deposits. The March 2026 timeline for interpreted results provides a clear milestone for evaluating the project's potential, with implications for future exploration decisions and resource estimation.
