Oroco Intersects 18.50 G/T Of Gold Over 2.0 Meters


October 8, 2008

VANCOUVER, BRITISH COLUMBIA – (Marketwire – October 8, 2008) – Oroco Resource Corp. (“Oroco” or the “Company”) (TSX-V: OCO) is pleased to announce the results from an additional seven diamond drill holes at its 100% owned Cerro Prieto Property in Sonora State, Mexico.

Highlights of the current results include:

  1. A total of 22 drill holes have been completed and all have intersected the mineralized shear zone;
  2. CP013 intersected 23.1 meters (10.7 meters true thickness) averaging 0.95 g/t Au, 9.7 g/t Ag, 0.62 % Pb and 1.58% Zn included within a 73.6 meter section (34.0 meters true thickness) averaging 0.40 g/t Au, 4.8 g/t Ag, 0.35% Pb and 1.23% Zn;
  3. CP014 intersected 2.0 meters (1 meter true thickness) averaging 18.50 g/t Au, 85.7 g/t Ag, 0.31% Pb and 1.65% Zn included within a 64.0 meter section (31.0 meters true thickness) averaging 1.01 g/t Au, 13.7 g/t Ag, 0.16% Pb and 0.52% Zn;
  4. CP015 intersected 4.0 meters (2.5 meters true thickness) averaging 0.72 g/t Au, 55.2 g/t Ag, 0.17% Cu, 2.94% Pb and 7.94% Zn included within a 22.0 meter section (13.5 meters true thickness) averaging 0.36 g/t Au, 15.9 g/t Ag, 0.87% Pb and 2.27% Zn;
  5. CP018 intersected CP018 intersected 176.5 meters (65.4 meters true thickness) averaging 0.12 g/t Au, 4.1 g/t Ag, 0.30% Pb and 0.93% Zn.

The 22 holes drilled to date (5800 meters in total) are spaced horizontally and vertically at 100 meter intervals and have traced the mineralized shear zone over a strike length of 600 meters to a depth of 400 meters below surface. The holes reported in this release are at the southern end of the known mineralized shear zone where, historically, grades have been lower than to the north.

The last hole in the Phase 1 program has just been completed and is located 325 meters along strike to the north under the previously reported (see press release dated September 9, 2008) trench which assayed 79.7 g/t Ag, 0.401 g/t Au, 0.32% Pb and 0.47% Zn over a 36.3 meter section.

Trenching is continuing along the strike length of the mineralized zone on surface. All assays should be received by the end of October at which time the company will formulate its plans for a Phase 2 drill program.

The Cerro Prieto polymetallic project is located in Sonora State, Mexico and consists of three mineral concessions totaling 2,523 hectares.  Oroco holds a 100% interest in these concessions.  In April of this year a Phase 1 drill program commenced and, at the completion of this 23 hole program the mineralized zone will have been drill tested vertically at 100 meter centers along a strike length of at least 600 meters to a depth of 400 meters allowing the calculation of an initial estimation of resources.

The company is excited about the extent and consistency of the mineralization along the strike length and to depth, and with the potential to expand the zone in all directions.

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.
