GreenX Metals Limited (GreenX or Company) and its joint-venture (JV) partner Greenfields Exploration Ltd. (Greenfields) announced the results of preliminary analysis on three historical samples of native copper nodules from the RC Project (ARC or the Project) in Greenland. The samples were obtained from a recently opened government geological storage facility in Copenhagen. Three native copper samples found at Discovery Zone, Neergaard Dal, and Neergaard South within ARC were subject to advanced micro-XRF scanning, a more precise and comprehensive technology when compared to more common portable XRFs. The best analysis result was for a sample found immediately south of the Discovery Zone, which indicated median copper purity of 99.8%, with 255 g/t silver, 0.004% antimony and 0.000% arsenic. The samples from Neergard Dal and Neergard South indicated copper purity of 99.7% and 99.4% respectively, with low to no deleterious elements detected in any of the samples. The high quality of the analysed samples is comparable to blister copper, a product typically produced by smelting prior to being sent to a refinery. Three samples of native copper i.e., near-pure copper metal found in nature, were identified: native copper from immediately south of the Discovery Zone prospect; fissure copper from the central Neergaard Dal prospect; and native copper from Neergaard South prospect. Notably, the existence of the samples from the Neergaard Dal and Neergaard South prospects was not previously known in the historical data set. Similarities to Keweenaw Peninsula: The ARC native coppers are of particular interest to the Company, given the potential for them to be geologically analogous to the Keweenaw Peninsula (Michigan, USA). The native copper at Keweenaw was extremely enriched, almost pure, with very little in the way of deleterious elements. Due to the high purity of the historical samples recovered, the Company considers these results to be reminiscent of the Keweenaw mineralisation, and it looks forward to future exploration results to substantiate this indication. The main by-product element found with the Keweenaw copper was silver, an element that is also recorded in the historical assays from ARC, and the currently analysed Discovery Zone sample containing 255g/t Ag. Notably, the records of the silver at Keweenaw are incomplete as it is reported that much of it was misappropriated by the miners, giving
testament to the silver size and quality. The historical mining companies at Keweenaw were instead focussed on the almost pure native copper, that in some cases weighed hundreds of kilograms. These extreme native copper occurrences were hosted in `fissures' (faults). Significantly, the native copper sample from Neergaard Dal is hosted within a fault, giving the potential for similarly intense mineralisation.
