Oroco Receives Approvals For Drill Programs

June 23, 2021

VANCOUVER, British Columbia – (June 23, 2021) Oroco Resource Corp. (TSX-V: OCO, US: ORRCF) (“Oroco” or “the Company”) is pleased to announce that it has received approval from the Chihuahua State and Sinaloa State offices of the Mexican Secretariat of Environment and Natural Resources (“SEMARNAT”) to conduct drill programs from a collective 55 approved drill locations in the Brasiles Zone and the North Zone of its Santo Tomas Project.  While initial plans are for one hole per location, if warranted by results, the Company will be able to target different areas of the zone with multiple holes per location.

The Chihuahua State office of SEMARNAT approved the Company’s 46 drill locations, supporting 28-person camp, and access road network the Brasiles Zone.  The program will test the Brasiles Gossan zone (identified in surface exposure and further defined by the 3D IP program) and the Western blind target identified by the 3D IP program.

The Sinaloa State SEMARNAT office has approved a non-environmental impact 9 drill location program in the North Zone which is intended to confirm and expand the historical North Zone resource.  While this approval does not allow for the construction of new roads, the deployment of light, highly portable drill rigs with helicopter support will offset this restriction.  During this initial program, the Company will pursue the unified environmental impact assessment and change of land use permit, as recommended by SEMERNAT, which will allow for the construction of access roads, more drill locations and supporting infrastructure throughout the North Zone.

The Company will now proceed to install water storage and distribution facilities to support the drilling at the Brasiles and North Zones and will shortly mobilize drill equipment to commence the drill programs.

“We are very pleased with the cooperation and support we have received from the Sinaloa and Chihuahua offices of SEMARNAT” stated Ian Graham, the Company’s President.  “We see this positive relationship as integral to the success of the Santo Tomas Project.”


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.
