Oroco Intersects 0.214 g/t Au, 361.8 g/t Ag, 2.40% Pb and 4.76% Zn over 11.2 Meters.

June 16, 2008

VANCOUVER, BRITISH COLUMBIA – June 16, 2008. Oroco Resource Corp. (OCO-TSX.V) is pleased to report results from its drill program on the Cerro Prieto program in Sonora State, Mexico.

Highlights of the drilling include:

To date a total of 1,426.8 meters has been completed in six diamond drill holes. The holes have been targeted to confirm and expand a 725 meter long mineralized zone previously outlined by Morgain Minerals in 1998 and 1999. Morgain calculated a resource of 8.5 million tons with a 4.4 g/t Au equivalent (the resource was calculated prior to NI43-101).

The mineralized zone at Cerro Prieto consists of a shear zone up to 60 meters thick with an abundance of quartz veining, brecciation, stringer sulphides and oxides. Often, the bottom contact of the shear zone consists of a brecciated, mineralized quartz vein up to 10 meters thick.  Oroco geologists previously sampled an underground adit along the mineralized zone that assayed an average of 3.45 g/t Au, 6.22 g/t Ag, 0.54% Pb and 1.27% Zn over a sampled strike length of 408 metres on the 800 level.

The locations of the six completed holes and the next ten planned holes are shown on the longitudinal section on the Oroco website (here).

Assays have been received for the first two holes and are presented in the following table.

Core is split with a diamond saw on site and half of the core is placed in plastic sample bags. A company employee delivers the samples to the ALS Chemex preparation laboratory in Hermosillo. The samples are crushed and a portion is pulverized which is sent to the ALS Chemex laboratory in Vancouver Canada for assaying.

Oroco also has a Quality Assurance – Quality Control program in place to ensure accuracy of sampling and assaying.The project is being run in the field by Antonio Montante, an experienced geologist from San Luis Potosi. The project is supervised by Ken Thorsen, a director of the company and the company’s Qualified Person.

Oroco is a Canadian mineral exploration company which holds a 100% interest in six mineral concessions in Mexico.   The company is initially focused on its Sonora concessions, comprising the Cerro Prieto Mine and the nearby 2,508 hectare Cerro Prieto North concession.   In addition, Oroco holds three mining concessions in the state of Guerrero totaling 293 hectares.

Director Ken Thorsen, BSc Geological Engineering, P Eng, is the company’s Qualified Person for the Cerro Prieto Project.   Mr. Thorsen is responsible for the current exploration and development program and has reviewed the content of this release.

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.
