GreenX Metals Ltd. announced the results from the first site visit to the Arctic Rift Copper Project (ARC) in Greenland. The results of this work program have demonstrated the high-grade nature of the known copper sulphide mineralization, and wider copper mineralization in fault hosted Black Earth zones and adjacent sandstone units. The exact position of a native copper fissure at the Neergaard Dal prospect was also identified. This new information is key to future targeting of stratabound copper of both types. The field team completed a site visit to the Discovery Zone and Neergaard Dal prospects in the northern half of ARC. A sample at the Discovery Zone prospect yielded a peak reading of 53.8% Cu with 1,074 g/t Ag; and an average reading of 39.3% Cu and 1,065 g/t Ag. Other samples at the Discovery Zone yielded 12.09% Cu and 373 g/t Ag; with a median result of some being 5.82% Cu and 448 g/t Ag. One of the objectives of the site visit was to verify the Discovery Zone, given the extremely high grades reported historically. The location of the high-grade material was apparent from over 150m altitude and on the ground. Finding the native copper mineralisation at Neergaard Dal was similarly easy. Historically, a copper fissure was noted but this was recorded prior to GPS and so the exact location was unknown. A well-mineralised fissure was quickly identified, which bodes well for finding additional fissures in this area and further afield. Portable XRF (pXRF) readings were taken of the collected samples. Samples were collected from the Discovery Zone fault-hosted `Black Earth' and sandstone-hosted mineralisation. Historical sampling from this area demonstrates 4.5m true width of 2.15% Cu, 35.5 g/t Ag. The dominant copper mineral is chalcocite, which occurs as pervasive thin veins that sometimes produce visually obvious green oxides like malachite. The primary trend of the mineralisation appears to be bounded by a sub-vertical sandstone fault that produces a prominent ~2m ledge (5). As the mineralised fault is softer than the sandstone, it has a negative relief and is superficially obscured in places. The Black Earth material comprises a variety of different rock types hosted by fine-grained material.
There appear to be at least four subtly different sandstones and mudstones, as well as fragments of very dense, almost complete chalcocite1. This dense material is almost the same as that is historically reported to grade 53.8% copper (`Cu') and 2,480 silver (`Ag'). A handheld XRF unit was used to conduct multiple scans of sample A1199a, which also yielded a peak reading of 53.8% Cu with 1,074 g/t Ag2; and average reading of 39.3% Cu and 1,065 g/t Ag (6). This high-grade sample was recovered from 35m along strike to the west of where a similar grading float sample was historically collected. The Company cautions that pXRF readings are indicative and not absolute. It is possible that surface oxidation and contamination produced lower readings than may be recorded from the central mass of A1199a. The shape of sample A1199a is suggestive of something tabular, like that of the historical sample with extreme grades. This tabular shape could result from a vein, like the fine-grained chalcocite veinlets seen throughout the area or a layer within the sedimentary horizon. Notably, the other Black Earth material hosting this high- grade material is also mineralised, as is the surrounding sandstone. The median XRF reading of the six fragments (A1199a to A1199f) is 12.09% Cu and 373 g/t Ag; and the median of all the 49 Black Earth readings (including A1197a-d, A1198a-d) is 5.48% Cu and 89 g/t Ag. The samples 1197 and 1198 are of interest as they are from an area where the Black Earth is well exposed, and has an apparent width around 5 m3.
