ANCOUVER, British Columbia – (March 7, 2011) Oroco Resource Corp. (TSX-V: OCO) (“Oroco” or “the Company”) is pleased to announce that it has extended the mineralized zone at its Cerro Prieto Project over 500 meters to the south from the current resource area which was the subject of a recent Preliminary Economic Assessment (the “Current Resource Area”).  See the Company’s news release of December 15, 2010.

The Company conducted a surface sampling program from 150 N, being the southern edge of the Current Resource Area, along approximately 500 meters of strike extension to line 350 S.  It is important to note that the samples were taken only where the mineralized zone was exposed and no attempt was made to extend the exposures.  Results of the sampling program are contained in the following table.

The results of samples from 150 N to 000 were previously stated in a press release of November 28, 2008 which reported surface sampling from 000 to 1250 N. 

Line 000 to 250 S are contained within the Elba concession, a 5.82 ha concession to which the Company recently acquired a right to purchase (along with the 20 ha Huerto De Oro and 9.79 ha Reyna De Plata concessions which lie to the east of the Cerro Prieto Project).  The Company had intentionally left an untested 150 meter buffer zone between the southern edge of the Current Resource Area and the northern boundary of the Elba concession.  Locations of the Elba concession and grid references may be viewed on the Oroco website at 
www.orocoresourcecorp.com/projects-Cerro-Prieto-Project-Maps-and-Sections.html.

The recent sampling program was undertaken for reason that the Company is planning a drill program to increase the size of the Cerro Prieto deposit beyond that delineated within the mine plan presented in the recent Preliminary Economic Assessment.
