OROCO ANNOUNCES FIRST SAMPLING RESULTS FROM CERRO PRIETO NORTH PROPERTY

VANCOUVER, BRITISH COLUMBIA – April 30, 2008 –Oroco Resource Corp. is pleased to announce the results of a recent mapping and sampling program on its 100% owned Cerro Prieto North claim, part of its Cerro Prieto project in Sonora, Mexico.Highlights of the sampling include:

  1. 2.11 g/t Au and 142.0 g/t Ag over 0.6 meters
  2. 2.18 g/t Au and 134.0 g/t Ag over 1.2 meters
  3. 1.70 g/t Au, 115.0 g/t Ag, 2.26% Pb and 3.17% Zn over 1.0 meter

The southern boundary of the 2,508 ha Cerro Prieto North claim is located approximately two and one-half kilometers north of the historical Cerro Prieto Mine, situated on Oroco’s San Felix and San Francisco concessions, where a drill program is currently underway.  The northwest striking structural zone can be traced geologically across 1.7 kilometres of strike length of the San Felix and San Francisco concessions and onto the Cerro Prieto North concession.  It outcrops on the Cerro Prieto North property over a strike length of approximately 300 meters starting approximately 2.6 kilometres north of the property boundary.  In total, the structure has a potential strike length of 4.8 kilometers on the Cerro Prieto North property. 

The geological structure in this location is relatively steeply dipping and intersects relatively flat lying sediments and volcanics.  An Oroco geologist recently began sampling and mapping the showings and general geology of the area.  Results from the sampling along the 300 meter zone are shown in Table 1, below. Highly anomalous gold and silver values are accompanied by anomalous to highly anomalous lead and zinc values in the majority of the samples and indicate mineralization similar to that seen in the historical workings at the Cerro Prieto Mine.  Samples FCO 001 and FCO 002, FCO 005 and FC 006, FC 008 and FC 009, and FC 015 and FC 016 represent contiguous samples taken across the total width of the mineralized zone.

Regarding the significance to the Cerro Prieto Project of the identification of the mineralized structure and the assay results, Oroco President and CEO Stephen Leahy stated:  “We are extremely encouraged by the strong mineralization such at these outcroppings several kilometers along strike from the Cerro Prieto Mine.”Oroco is planning an extensive trench and sampling program on the Cerro Prieto North claim to further delineate the mineralized zone and a geophysical program to the north and south of the outcrop area to trace the zone under cover.  The results from this follow-up program will assist in defining future drill programs.

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 three Sonora concessions, comprising the Cerro Prieto Mine, a historic polymetallic deposit, 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.
