VANCOUVER, British Columbia ? (August 11, 2009) Oroco Resource Corp. (*TSX-V: OCO*) (?*Oroco*? or ?*the Company*?) is pleased to announce the initial results of its Phase Two field program commenced last month at the Cerro Prieto project in Sonora, Mexico.
As part of the 2009 exploration program, geologists sampled 900 meters of outcropping vein structure on the Argonauta concession, starting at the northern boundary of Oroco?s Cerro Prieto concessions. The samples returned high grade or anomalous gold values along the entire strike length tested. This represents a significant extension of the Cerro Prieto vein system successfully tested in Oroco?s 2008 Phase One exploration program. Together with the 1,250 meters of strike length tested in 2008, this increases the strike length on which high grade gold has now been confirmed to over two kilometers.
*Highlights of the program are as follows:*
1. The Cerro Prieto vein and mineralized zone extends for at least 900 meters north of that previously outlined by Oroco in the 2008 trenching and drilling program.
1. Intermittent sampling along the mineralized zone resulted in highly anomalous results in gold, silver, lead and zinc.
1. Complicated structural preparation (pre-mineralization faulting) in the northern 200 meters of the zone is accompanied by high gold assays including 14.90 g/t/1.0 m, 10.05 g/t/1.0 m and 21.90 g/t/0.8 m.
1. Highly anomalous lead (up to 5.4%/0.5 m) and zinc (up to 2.22%/1.0 m) values are also associated with the Cerro Prieto vein system.
A total of 122 samples were collected along a 900 meter strike length and were selectively taken across areas of veining, brecciation or fault gouge only where they are exposed ? no physical trenching was attempted. All samples with the exception of two are channel samples, with the two exceptions being composite grab samples. In the collection of channel samples attempts were made to get equal volumes of each rock type in the sample.
Sampling results are grouped into five geographic areas identified on the accompanying map (to view map go to http://www.orocoresourcecorp.com/projects-Cerro-Prieto-Project-Maps-and-Sections.html).
Area A, where 37 samples were taken, consists of the 700 meter long extension of the Cerro Prieto vein traced by drilling and trenching on the original Cerro Prieto claims. Of the 37 samples taken, 14 assayed greater than 0.5 g/t Au as shown in Table 1.
