(TSX-V: OCO, OTC: ORRCF) (“Oroco” or “the Company”) is pleased to announce the receipt of the assay results from its initial drilling campaign at its Santo Tomas property (the “Property”) in northwestern Mexico. Eight drill holes have been completed to date, all in the North Zone (see Figure 1, attached). An additional two drill holes in the North Zone are completed, pending surveying. A further two drill holes are in progress in the North Zone, and another in the Brasiles Zone. Assays reported herein are for the first three holes (N001 to N003) comprising 2,350m of HQ3 and NQ3 diameter diamond drilling which produced 1,492 assay samples. The Company is very pleased that the initial drilling results confirms the following: Copper grades in holes N001 to N003 are comparable to the historical drilling reported on each of the cross-sections drilled to date. Drilling results in N001 to N003 conform closely to, and confirm the geological conclusions and the 2009 Gradeshell model of Cu > 0.3% (the “2009 Gradeshell Model”) contained in the current Technical Report (‘the “Technical Report”) (Bridge, 2019: See SEDAR, or the Company’s website www.orocoresourcecorp.com/projects/technical-reports/). (see Figures 2, 3 and 4, attached). Geological logging indicates copper is present as chalcopyrite and bornite dissemination and vein fillings. Pyrite is relatively sparse in the main drill intersections. Molybdenum, gold and silver are elevated across the width of the North Zone and provide about a 15 to 20% contribution to the copper equivalent grade, without factoring for metallurgical recoveries. Fracturing, Laramide intrusive dikes, mylonite zones, veining and sulphide mineralization are controlled by faulting co-eval with the formation of the North Zone deposit. The deposit is confirmed in drilling with a strike of N20°E and a dip of 50-55°W, as reported in the Technical Report. Sulphide mineralization in the main intersections on the North Zone are hosted in strongly potassic-altered volcanic and intrusive rocks with an overprint of phyllic alteration. The footwall of the North Zone is propylitic-altered andesite volcanic rock with disseminated and vein filling pyrite, explaining the extreme Chargeability High response in the 3D IP survey...
