GreenX Metals Limited (ASX:GRX, LSE:GRX) is pleased to advise that its Tannenberg Copper Project (Tannenberg or Project) has expanded to 1,900km2 from 272km2, which includes a new region containing additional historic drill intercepts. The expanded project is highly prospective for sediment-hosted (Kupferschiefer type) copper deposits. The Tannenberg exploration licence now covers 1,900 km2, a seven-fold increase from the original 272 km2 project area. The original Tannenberg exploration licence has been extended for a further three years (Tannenberg 1), and a second, large Tannenberg exploration licence (Tannenberg 2) covering 1,628km2 has been awarded, valid for three years. The Tannenberg project is held through an earn-in agreement whereby GreenX can earn a 90% interest. In January 2025, Tannenberg was one of eight early-stage exploration projects selected by BHP for the 2025 BHP Xplor program, with funding from BHP Xplor currently being used to accelerate the geological concept build-out and exploration timeframe at Tannenberg, including the newly expanded license area. The Tannenberg area contains historically producing copper mines and multiple historical drill intercepts, with excellent potential for new discoveries of shallow (50 m to 500 m), large scale and high-grade copper and silver mineralisation, with much of the new expanded licence area remaining untested by modern exploration.

The Company expects the first collection of magnetic data to begin within weeks; core relogging and gravity data collection will be ongoing over the summer months. Key features of the 2025 exploration program will include relogging, reassaying and scanning of archived core; completion of an airborne magnetic and radiometric survey; collection of additional ground gravity measurements; reprocessing of archived geophysical data; and collation of historic mining and production data.
