Oroco Announces the Start of Drilling at Santo Tomas


July 29, 2021

VANCOUVER, British Columbia – (July 29, 2021) Oroco Resource Corp. (TSX-V: OCO; OTCQB: ORRCF) (“Oroco” or “the Company”) is pleased to announce that it has commenced diamond core drilling at its Santo Tomas copper project, with the first drill hole collared and in progress.  A second drill rig is scheduled to begin operating next week, and a third rig, constructed for the Company by Hydracore Drills Ltd. of Canada, is in transit to the project.  The drill hole currently in progress is located in the North Zone and represents the first drill hole collared anywhere on the property since 1993.  The initial drilling is intended to confirm the presence of historically defined polymetallic copper mineralization and to begin the development of new mineral resource models at Santo Tomas.

Commenting on the start of drilling, Oroco’s CEO, Craig Dalziel, stated "We are extremely pleased to be able to initiate a new generation of drilling at Santo Tomas at a time when the acceleration of large copper projects is essential for global economic growth and stability. We are anxious to confirm and extend the historical resources at the North and South Zones, and to commence exploration at the Brasiles Zone, where our 3D DCIP program indicated extensive and compelling chargeability features.”

The initial holes in the drill program will be collared in the North Zone and will be drilled at steep angles to the East-Southeast.  While heavy rains have impacted roads and mobilization, causing the initial drill setups to be supported by helicopter, the rapidly rising reservoir has enabled the project team to revert to waterborne support of the drilling program from the Company’s existing Buena Vista base camp.  The light and highly (man-) portable drills being deployed by the Company allow for drilling at favourable locations with no environmental impact.  Targeting for drilling is being informed by the recently completed 3D DCIP survey which has defined significant chargeability features that correlate well with mineralisation known from historical drilling and which features continue beyond the mineralization defined by that drilling.

ABOUT OROCO:

The Company holds a net 73.2% interest in the collective 1,172.9 ha Core Concessions of the Santo Tomas Project in NW Mexico.  The Company also holds a 77.5% interest in 7,807.9 ha of mineral concessions surrounding and adjacent to the Core Concessions (for a total project area of 22,192 acres).  The Project is situated within the Santo Tomas District, which extends from Santo Tomas up to the Jinchuan Group’s Bahuerachi project, approximately 14 km to the north-east.  Santo Tomas hosts a significant copper porphyry deposit defined by prior exploration spanning the period from 1968 to 1994. During that time, the property was tested by over 100 diamond and reverse circulation drill holes, totaling approximately 30,000 meters. Based on data generated by these drill programs, a historical Prefeasibility Study was completed by Bateman Engineering Inc. in 1994.

The Santo Tomas Project is located within 160km of the Pacific deep-water port at Topolobampo and is serviced via highway and proximal rail (and parallel corridors of trunk grid power lines and natural gas) through the city of Los Mochis to the northern city of Choix. The property is reached by a 32 km access road originally built to service Goldcorp’s El Sauzal Mine in Chihuahua State.

These historical resource estimate models are based upon historical resource estimates prepared by John Thornton in 2011. While, in the opinion of Dane A. Bridge, author of the revised NI 43-101 standard technical report, Geology, Mineralization and Exploration of the Santo Tomas Cu-(Mo-Au-Ag) Porphyry Deposit, Sinaloa, Mexico dated April 21, 2020 (the “Report”), reliable estimation practices were used, in order to upgrade or verify the historical estimations, resampling and assay of historical drill samples, twinning of historical drill holes, and a new program of regularly spaced drilling is required. No qualified person has undertaken sufficient work to classify the current mineral resources or mineral reserves upon which these models are based and the Company is not treating the estimates as current estimates of the mineral resources. The Company gives no assurance that either these models or the historical resource estimates upon which they are based are accurate, and does not undertake any obligation to update the models or to release publicly any update or revisions of the resource estimates except as required by applicable securities law. The reader is cautioned not to rely upon these models or the historical resource estimates upon which they are based.
