Grafton Resources Starts Heliborne Mobile MT Geophysical Survey at Alicahue Gold-Copper Project, Chile

Grafton Resources Starts Heliborne Mobile MT Geophysical Survey at Alicahue Gold-Copper

Project, Chile

February 12, 2026

Vancouver, British Columbia – February 12, 2026 – Grafton Resources Inc. (CSE: GFT; OTCQB:

GFTFF; FSE: K8L0) (“Grafton” or the “Company”) is pleased to announce that Expert Geophysics

Surveys Inc. has started a planned 80 line-kilometre mobile magnetotelluric (“MobileMT”)

heliborne survey at the Alicahue Gold-Copper Project, Valparaiso, Chile. This survey will cover the

entirety of Grafton's Alicahue Gold-Copper Project (the “Property” or the “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 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 1 km to 2 km, dependent on the conductivity distribution of the local geology.

Campbell Smyth, Chairman of the Company, commented: " We expect the Mobile MT 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.”

exploration, development and mining activities; actual exploration or development plans and costs

differing materially from the Company’s estimates; the ability to obtain and maintain any necessary

permits, consents or authorizations required for mining activities; environmental regulations or hazards

and compliance with complex regulations associated with mining activities; climate change and climate

change regulations; fluctuations in exchange rates; the availability of financing; operations in foreign and

developing countries and the compliance with foreign laws, remote operations and the availability of

adequate infrastructure; fluctuations in price and availability of energy and other inputs necessary for

mining operations; shortages or cost increases in necessary equipment, supplies and labour; regulatory,

political and country risks, including local instability or acts of terrorism and the effects thereof; the

reliance upon contractors, third parties and joint venture partners; challenges to title or surface rights;

the dependence on key personnel and the ability to attract and retain skilled personnel; the risk of an

uninsurable or uninsured loss; adverse climate and weather conditions; litigation risk; and competition

with other mining companies. As a result of these risks and uncertainties, and the assumptions underlying
