Full Summary

IRIS Metals Limited (ASX: IR1) has announced the commencement of exploration activities at the Finley Basin Tungsten Project in western Montana, USA. This follows a comprehensive review of historical exploration data from Union Carbide, which identified tungsten mineralization. The project aims to verify and expand on this historical data through a planned drilling program expected to start in Q3 2026. The program will involve up to 7,000 meters of diamond drilling across 16 drill hole locations. The Finley Basin Project is strategically important as it adds tungsten exposure to Iris Metals' existing lithium and critical minerals portfolio in South Dakota. The project benefits from established infrastructure and year-round access.
