Oroco Reports On South Extension Drilling At Cerro Prieto
May 14, 2012
VANCOUVER, British Columbia – (May 14, 2012 – Oroco Resource Corp. (TSX-V: OCO) (“Oroco” or “the Company”) is pleased to report additional results from the 2011 and 2012 exploration and infill drill program at its Cerro Prieto Project in northern Sonora State, Mexico.
As part of this overall drill program, the Company tested the southern extension of the mineralized structure on strike from the southern boundary of the area containing the current resource, a length of 500 meters from Line 150N to Line 350S. All but one of the completed drill holes intersected intervals of gold mineralization greater than the cut-off grade used in the existing resource estimate for Cerro Prieto.
Highlights of the results include:
- Holes CP067 and CP068A, both drilled on line 100N (50 m south of the boundary of the current resource estimation), intersected 10.35 m of 0.65 g/t Au and 11.2 m of 0.60 g/t Au respectively;
- At Line 200S, hole CP095 intersected 15.0 m of 0.50 g/t Au in one of two zones intersected;
- At Line 250S, hole CP097 intersected 9.00 m of 3.29 g/t Au in one zone and 12.65 m of 0.45 g/t Au in a deeper zone; and
- At Line 300S, hole CP098 intersected 9.15 m of 0.57 g/t Au
The drill holes were spaced to test the structure to a maximum vertical depth of 100 meters at 50 meter intervals along strike. All drill holes intersected the structure and in some cases intersected more than one mineralized zone. Full results are shown in the following table.

The south end of the current proposed open pit extends south from line 150N to Line 000, however as no drilling had previously taken place south of line 150N, the Current Resource is presently estimated only as far south as Line 150N. Drill results within this area reported herein include intersections of mineralization at gold grades greater than the cut-off grade used in the Company’s previously announced resource calculation and Preliminary Economic Assessment. Previously reported surface trenching from lines 150N to 000 also include intervals of mineralization at grades greater than the cut-off, including intervals of 5.2 meters averaging 4.79 g/t Au and 21.5 g/t Ag (at 150N), 9.8 meters averaging 4.08 g/t Au and 36.2 g/t Ag (at 100N), and 6.1 meters averaging 2.05 and 9.0 Ag (at 050N).
Further south along strike, intersections from drilling at 100S to 150S and 250S to 300S are of particular interest because higher grade material was intersected under surface trenches with higher grade results (see press release March 7, 2010), including 6.0 meters averaging 1.28 g/t Au and 12.8 g/t Ag (at 100S), 4.7 meters averaging 2.36 g/t Au and 28.0 g/t Ag (at 150S), 5.5 meters averaging 4.65 g/t Au and 53.3 g/t Ag (at 272S) and 8.0 meters averaging 2.49 g/t Au and 93.4 g/t Ag (at 300S).
