Mogotes Metals Reports Drilling Results At Filo Sur Project
Mogotes Metals Inc. provided an update on drilling results from its flagship Filo Sur project, located immediately south of, and along strike from, the Filo del Sol copper-gold-silver discovery being advanced by BHP and Lundin Mining. Highlights of FS_DDH_016: 180.0 m @ 0.98% CuEq from 108.0 m (0.51% Cu, 0.37 g/t Au, 2.8 g/t Ag, 119 ppm Mo) including: 58.0 m @ 1.77% CuEq from 111.0 m (0.90% Cu, 0.70 g/t Au, 3.6 g/t Ag, 228 ppm Mo), 7.0 m @ 1.01% CuEq from 188.0 m (0.54% Cu, 0.38 g/t Au, 1.8 g/t Ag, 118 ppm Mo), 7.0 m @ 1.29% CuEq from 236.0 m (0.91% Cu, 0.16 g/t Au, 11.9 g/t Ag, 143 ppm Mo), 9.0 m @ 2.84% CuEq from 276.0 m (1.32% Cu, 1.34 g/t Au, 7.5 g/t Ag, 105 ppm Mo). Shallow copper and gold mineralization starts at 108 m depth. Surface channel samples collected by Mogotes immediately above and along strike of the drill intercepts returned anomalous copper and molybdenum values. Together with a molybdenum-in-soil anomaly measuring approximately 400 by 800 m, these results support the interpretation that the mineralized hydrothermal system has significant extent, including possible continuation beneath a thin veneer of scree cover. The limits of the mineralization intersected in FS_DDH_016 have not yet been defined by drilling and remain untested to the northwest and southeast along the strike of the Macho Muerto Fault Zone, and at depth. Multiple overlapping hydrothermal events were observed in FS_DDH_016, including early potassic-altered quartz diorite porphyry intrusions, early-stage quartz stockwork veining consisting of "A" and "B" family veinlets with chalcopyrite, chalcopyrite-bearing magmatic-hydrothermal breccias altered to anhydrite and biotite, later copper-bearing vein generations, and subsequent fine-grained, epithermal overgrowths of dark copper-bearing sulfide minerals including probable covellite, digenite, bornite and enargite. Early potassic alteration is overprinted by silica and quartz-sericite-chlorite, consistent with the telescoping of lithocap and epithermal alteration over deeper potassic alteration. These cross-cutting relationships indicate multiple mineralizing events within the hydrothermal system. Increasing potassic alteration at depth was observed at 287.85 m in FS_DDH_016, where the mineralized breccias and quartz diorite porphyry are bounded by a strand of the Macho Muerto Fault, with drilling continuing into less-mineralized but increasingly potassic-altered andesite wall rock. The intensity of potassic alteration associated with phreatic breccias in the andesite wall rocks increases with depth. This trend, located immediately adjacent to an IP chargeability high, is interpreted by Mogotes geologists to represent another potentially mineralized porphyry target at depth. In FS_DDH_016, quartz diorite porphyry dikes and mineralized breccias are emplaced along the trans-Andean Macho Muerto Fault Zone. Within the Filo Sur project, the Macho Muerto Fault Zone extends over approximately 10 km: from the Meseta target in the north, through Luz del Sol to Albor (a 3 km trend), then a further 7 km southeast to the newly discovered Cruz del Sur porphyry system. FS_DDH_019 was collared opportunistically to acquire more information on the discovery prior to the next season. Company geologists believe that the hole may have tested the Macho Muerto Fault Zone at an oblique, shallow angle, limiting its effectiveness in crossing the principal breccia body; FS_DDH_019 is therefore not interpreted as an adequate drill test of the mineralized breccias. Thin mineralized breccia intercepts were encountered, and additional drilling will be required to test the northwest continuation of the breccias: Highlight assay 14.0 m @ 0.82% CuEq from 48.0 m (0.41% Cu, 0.35 g/t Au, 1.6 g/t Ag, 60 ppm Mo). Meseta: Mogotes geologists encountered highly fractured, dense silica and faulting while drilling Meseta target holes FS_DDH_011 (20 m depth) and FS_DDH_012 (116 m depth). The drilling did not reach the targeted depths and the rigs were remobilized to drill the Luz del Sol targets to make best use of the limited summer months. The Meseta target remains untested and a target for future seasons. Camino: Due to technical drilling issues, FS_DDH_009 was unable to reach target depth of 1,200 m to test the primary MT resistivity low. The hole was weakly mineralized and the target potential will be re-evaluated. Cumbre: Drill holes FS_DDH_017 (10 m depth) and FS_DDH_018 (47 m depth) were not completed to target depth due to forecast winter weather conditions necessitating the completion of the drill season in May. Both short drill holes encountered lithocap style, moderate to strong silica-clay alteration. These areas remain priority targets for the next drill season. Drill hole FS_DDH_014 was intended to test the coincidence of MT and IP resistivity lows that overlap with IP chargeability highs. The hole encountered weak to strong argillic to advanced argillic alteration affecting a thick sequence of andesitic to dacitic pyroclastic rocks. This alteration is suggestive of a high-level porphyry lithocap environment telescoped over nearby porphyry-related mineralization encountered in FS_DDH_016.
