Oroco Resource Corp. Drills 187.9 M of 0.58% Cu Equivalent At Santo Tomas
Oroco Resource Corp. announced assay results from drill holes S004 through S018 (8,547 m of drilling) of its South Zone drilling program at its Santo Tomas property (the "Property") located in northwestern Mexico. To view an interactive 3D model that includes the South Zone results. South Zone Program: The Company has now completed a 21-hole South Zone drill program (12,154 m) designed to confirm and test the South Zone mineralized structures, with the assay results up to drill hole N018 now being reported, and those of holes S019 through S021 currently pending. All drill holes tested the deposit approximately perpendicular to its structural attitude. Core intervals are within approximately 10% of true thickness. Assay results and cross-sections of all South Zone, North Zone and Brasiles Zone drill holes released to date are available at the Company's website. Historical drilling, surface geological mapping, and the Dias Geo 3D Induced Polarization survey have defined near-surface mineralization projected to 400 m below the surface along 2,000 m of strike length in the South Zone. The South Zone is only partly tested by the current drill program. However, the historical drilling and the 2022-2023 drill program conclusively define a NNW to NNE trending zone of faulting, Laramide-age intrusion, hydrothermal breccias and mineralization along the entire two kilometer corridor south of drill hole N034 of the North Zone. The northern segment of the South Zone, between drill holes N034 and S012, representing a 500 m long undrilled corridor, will be tested in a future drilling program. The middle segment of the South Zone extends from drill hole S012 southward to hole S007 (Plates SZ-49 to SZ-63). Current drilling demonstrates a zone of moderate-grade, shallow-seated mineralization to a depth of 200 to 400 m below surface along a strike length of approximately 700 m. Continuity in this area must be confirmed by additional drilling. The southern segment of the South Zone extends southward from drill hole S007 along a strike length of approximately 800 m. Drill holes S004 to S017 (Plates SZ-47 to SZ-38), including the previously released S003 (277.4 m of 0.39% CuEq) and S004 (127.0 m of 0.41% CuEq), demonstrate continuity of good grade mineralization within a southwest plunging zone 300 m in width, extending from surface to 200-400 m in depth. As these drill holes test an area of the South Zone that begins within and extends beyond the historical resource, they have the potential to add significant tonnage to the mineral resource estimate being prepared in support of the planned Preliminary Economic Assessment. Drilling results - middle segment of the south zone: Drill hole S005 (Plate SZ-51), collared on the west side of the higher chargeability anomaly, returned 54.2 m of 0.28% CuEq. Drill hole S006 (Plate SZ-56), returned one of the best near surface drill holes in the South Zone to date with 146.6 m of 0.43 CuEq commencing within 20 m of surface. · Drill hole S007 (Plate SZ-49), collared on the eastern fringe of a chargeability anomaly returned only marginal mineralization. Drill holes S008 and S010 (Plate SZ-52), returned only marginal intervals of mineralization. · Drill hole S009 (Plate SZ-58), returned only two short intervals of good grade mineralization: 23.2 m of 0.39% CuEq and 24.3 m of 0.32% CuEq, but appears to correlate well with S006 to the south and S012 to the north. Drill hole S011 and S013 (Plate SZ-54), intersected only marginal intervals of mineralization. Drill hole S012 (Plate SZ-63), returned three mineralized intervals, with the main interval being 82.0 m of 0.42% CuEq. This intersection remains open to the north into the gap of drilling between the North and South Zones. Drilling results - southern segment of the south zone: Drill hole S004 (Plate SZ-47), returned three mineralized intervals, with a main interval of 127.0 m of 0.41% CuEq. Drill hole S014 (Plate SZ-41), collared approximately 120 m south of S003, cut and confirmed STE-54 while extending mineralization a further 200 m to depth (with the best grades found at depth). S014 returned three mineralized intervals: 44.0 m of 0.32% CuEq, 146 m of 0.28% CuEq, and 66.0 m of 0.34% CuEq. · Drill hole S015 (Plate SZ-44), returned three mineralized intervals, with the main interval being 179.2 m of 0.45% CuEq. · Drill hole S016 (Plate SZ-43), returned three mineralized intervals, with a significant main interval of 349.1 m of 0.40% CuEq. Drill hole S017 (Plate SZ-38), returned one main mineralized interval of 142.0 m of 0.27% CuEq. · Drill hole S018 (Plate SZ-44-A), returned three mineralized intervals, of which the most significant are 187.9 m of 0.58% CuEq and 234.3 m of 0.40% CuEq. The southern segment of the South Zone has a contrasting geology to the North Zone. The North Zone is a body of sheeted, west-dipping Laramide-age intrusive dikes and mineralization. Drilling of the southern segment has intersected similar west-dipping intrusions and mineralization but also cut a slightly younger overprinting of mineralized hydrothermal breccia bodies and a wide body of stockwork vein and fracture mineralization. Grades are comparable to North Zone and locally extend over wider intervals than seen in the North Zone to date.
