Aeromag survey identifies copper source beneath historic German mines

BERLIN - GreenX Metals Limited (ASX:GRX, LSE:GRX) has identified what appears to be the primary source of copper mineralization beneath historic mines at its Tannenberg Project in Germany, according to a company press release Tuesday.

The recently completed 58 square kilometer airborne magnetic and radiometric survey revealed deep metal source structures directly below the historic Richelsdorf copper district, which produced 416,500 tonnes of copper at grades between 0.8% and 1.2% from the 1800s to 1950s.

The survey identified the presence of the Mid-European Crystalline Zone (MECZ) beneath the mining district - the same geological structure considered to be the primary source of copper in the Kupferschiefer deposits across the European Copperbelt in Germany and Poland.

GreenX CEO Ben Stoikovich called the findings significant, noting this represents the first modern exploration at the site in 40 years.

"We have identified several previously unknown geological features below the historic Richelsdorf mines that will form a fundamental part of our understanding of the mineral system," Stoikovich said.

The geophysical anomalies extend beyond the survey area into the company’s recently expanded Tannenberg 2 license, potentially increasing the project’s exploration potential.

The survey was funded by BHP Xplor as part of an exploration collaboration that has been extended to October 31, 2025. Additional work programs include core logging, assaying, hyperspectral scanning of historical core, and reprocessing of historical geophysical data.

The company’s total license package now covers 1,900 square kilometers in an area considered strategically important for copper resources in Germany and the European Union.
