GreenX Metals Ltd has released its Quarterly Activities Report for the period ending June 2026. The report highlights the Tannenberg Copper Project in Germany, which has an Exploration Target estimated at 144 to 279 Mt at 0.9% to 1.4% Cu and 15 to 21 g/t Ag. This target captures mineralisation in the hanging wall and footwall of the Kupferschiefer shale, providing a modern view of the deposit. Additionally, the company has completed an early-stage mineralogy and processing study, confirming the potential for conventional flotation-based processing. In Greenland, fieldwork at the Eleonore North Project is underway, targeting gold, tungsten, and antimony mineralisation. Lastly, the Singapore Court has rejected Poland's application to set aside GreenX's ECT award, upholding the company's right to compensation.
