OROCO CONTINUES SOUTH ZONE SUCCESS WITH 221.7 M OF 0.45% CU EQUIVALENT

Vancouver, Canada, March 29, 2023 (GLOBE NEWSWIRE) -- Oroco Resource Corp. (TSX-V: OCO, OTC: ORRCF) (“Oroco” or “the Company”) announces the assay results from drill holes S019 through S021 (1,553 m of drilling) of its South Zone drilling program at its Santo Tomas property (the “Property”) located in northwestern Mexico (see Table 1, Figure 1 (Figure 3 on the Company’s website) and the South Zone cross-sections, attached).  To view an interactive 3D model that includes the South Zone results announced today, please use the following link: https://vrify.com or visit Oroco's website: www.orocoresourcecorp.com.

DRILL RESULT HIGHLIGHTS:

• Drill hole S020 (Plates SZ-46 & -47) returned 221.7m of 0.45% CuEq
• Drill hole S021 (Plates SZ-33 & -34) returned 145 m of 0.32% CuEq AND 89m of 0.34% CuEq

Richard Lock, Oroco’s CEO, commented: “I am very pleased to say that the overall Santo Tomas 2022-2023 drilling program has validated my decision to join Oroco approximately one year ago. The project is clearly meeting my expectations as a highly attractive acquisition target and I look forward to this assessment being further substantiated with the upcoming release of an updated Mineral Resource Estimate and the Preliminary Economic Assessment which will follow.”

SOUTH ZONE PROGRAM

The Company has now completed its current 21-hole South Zone drill program (12,154 m) designed to confirm and test the South Zone mineralized structures, with all results released. 

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. 

While the current drill program only partly tests the South Zone, the historical drilling and the 2022-2023 drill program conclusively define an NNW to NNE trending zone of faulting, Laramide-age intrusion, hydrothermal breccias and mineralization along the entire two-kilometer long corridor south of North Zone drill hole N043.

• The northern segment of the South Zone, between drill holes N043 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 holes S002 and S007 (Plates SZ-49 to SZ-63). Drilling demonstrates a zone of moderate-grade, shallow-seated mineralization to a depth of 200 to 400 m below the surface along a strike length of approximately 700 m.  Additional drilling is needed to confirm the continuity in this area.
• The southern segment of the South Zone extends southward from drill holes S002 and S007 along a strike length of approximately 800 m to drill hole S021.  Drill holes S001, S003 to S004, and S015 to S021 (Plates SZ-33 to SZ-47) demonstrate the continuity of good-grade mineralization within a southwest plunging zone at least 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 potentially add significant tonnage to the mineral resource estimate being prepared to support the planned Preliminary Economic Assessment (refer to Figure 1 and Plate SZ-33).
