VANCOUVER, Canada — (January 27, 2021) Oroco Resource Corp. (TSX-V: OCO, US OTC: ORRCF, BF: OR6) (“Oroco” or “the Company“) is pleased to announce significant results from the deep, three-dimensional, Induced Polarization (“3D IP”) geophysical survey of its Santo Tomas porphyry copper project in Mexico. The survey is now approximately 80% complete, and Oroco has received preliminary inversion data for all stations surveyed to date. The preliminary inversion model has successfully mapped the resistivity and chargeability characteristics along a swath 2.1 km wide by 4.3 km along strike over the South Zone, North Zone and part of the Brasiles Zone. The survey has reached the southern fringe of the prominent Brasiles zone gossans. Geophysical crews have now re-mobilized to complete the planned program and to prepare additional survey lines to enlarge the north and south-east extents of the current survey area. The Company has high confidence in the survey results.
