EV Resources Limited announced that a programme of channel sampling taken from within, and around an old underground exploration drive and crosscut at the Don Enrique copper project in Jauja Province, Peru, has been
completed and results received. EVR announced the commencement of exploration work at Don Enrique. The exploration drive and crosscut were developed in the 1960's by Peruvian company Cerro de Pasco. EVR's results demonstrate continuity of copper-silver-zinc mineralisation where underground development permitted sampling. It appears that the underground development was driven into the halo of mineralisation alongside one of two primary parallel polymetallic breccia structures. All underground sample results have been received, while results for surface sampling directly along the strike of the breccia orebody are awaited. A geophysics programme is due to commence on 21 November 2022. In total, 28.8 line km of Induced Polarisation (IP) testwork and a further 46.8 line km of ground magnetics will be conducted along the breccia structures to test what is interpreted, after mapping and geochemical sampling, to be a potential porphyry structure. A drilling permit application, which requires community approval under Peruvian regulations, is being finalised for submission. The fieldwork is supported by the local communities, with whom a constructive relationship has been established. Fertiliser, medical equipment and building materials have been supplied to the community as part of an outreach programme following the agreement reached in September 2022. The community is supplying casual labour to the exploration campaign. EVR has placed community relations at the centre of its site activities and will continue to build this important relationship. Underground Sampling Programme; Sampling of underground workings was carried out in the historic adits that were developed for exploratory purposes in the 1960's. A large number of samples have been collected along the west margin of a quartz breccia vein structure, following the strike (footwall). This structure exhibits a variety of quartz textures including milky white quartz, sinuous quartz saccharoid veinlets, hyaline quartz, and textures such as dog-tooth, buck, and ribbon quartz. This suggests that several generations of silica deposition occurred. In addition, there are sporadic occurrences of carbonate veins including ankerite and calcite. Copper mineralisation occurs as a dissemination in hydrothermal breccias, narrower quartz veins, and in a strongly silicified dacitic body . The identified minerals are predominantly chalcopyrite, traces of bornite, secondary copper such as malachite and azurite, and the local presence of covellite. Silver (Ag), molybdenum (Mo), zinc (Zn), and lead (Pb) mineralisation occur accompanying the Cu mineralisation, inlower concentrations, in the crosscuts perpendicular to the main structure, and towards a short, poorly developed secondary underground working. Strong Ag and Zn anomalies are reported in the crosscut sampling where silver sulfosalts, sphalerite, and traces of galena have been identified. The primary quartz breccia vein structure has a variable width of up to 20 metres. A second subparallel structure with a smaller width is located to the east of the main structure. Both structures present a general strike of NNW-SSE and continue for almost 1 km in length. Figures 7A and 7B demonstrate an idealised cross section of the mineralised structures and their possible behaviour at depth, including underground exploration work, with Cu anomalies in sampling carried out by EV Resources. The mineralised structures are located in strongly fractured and deformed volcanic units, predominantly pyroclastic rocks that alternate with lava flows, both of dacitic composition. In the vicinity of the mineralised structures, the volcanic units are affected by strong silicification and quartz-sericite alteration. Some underground crosscuts were also developed, but based on EVR mapping and sampling, they do not completely cut the breccia vein structure. Samples with anomalous Cu values occur in the crosscuts but not in the margin or the west wall of the structure, which represents a halo of the main structure.
