COPPER AND MOLYBDENUM IN
ADDITION TO AU-AG-PB-ZN MINERALIZATION IN DEEPEST HOLES DRILLED TO DATE AT
CERRO PRIETO
VANCOUVER, BRITISH COLUMBIA- (Marketwire �
September 18, 2008) - Oroco is pleased to
announce the results from an additional four diamond drill holes from its
Cerro Prieto Property located in Sonora State, Mexico.
HIGHLIGHTS
1. A
total of 18 holes have been completed and all holes have intersected the
mineralized shear zone;
2. CP011,
the first hole to return significant copper values, intersected a 1.5 meter
section (0.7 meter true) that averages 0.403 g/t Au, 79.3 g/t Ag, 2.07% Cu,
8.06% Pb, and 9.35% Zn in a 61.0 meter section (30.0 meters true thickness)
averaging 0.147 g/t Au, 13.3 g/t Ag, 0..74% Pb and 2.02% Zn. Within
the broader section and including the high grade copper section is an 8.5
meter (4.2 meters true thickness) long section averaging 0.188 g/t Au, 79.6
g/t Ag, 0.78% Cu, 3.71% Pb and 6.13% Zn;
3. Three
holes (CP009, CP010 and CP011) returned significant molybdenum assays (see
table) ;
4. CP008
intersected 48.3 meters (25.0 meters true thickness) averaging 0.542 g/t
Au, 20.4 g/t Ag, 0.45 % Pb and 0.99% Zn including 19.8 meters (10.2 meters
true thickness) averaging 0.904 g/t Au, 27.6 g/t Ag, 0.67% Pb and 1.35% Zn;
5. CP009
intersected 47.5 meters (32.0 meters true thickness) averaging 0.318 g/t
Au, 14.9 g/t Ag, 0.91% Pb and 2.59% Zn including 8.5 meters (5.7 meters
true thickness) averaging 0.746 g/t Au, 59.7 g/t Ag, 3.3% Pb 5.45% Zn, and
0.06% Mo;
6. CP010
intersected 77.2 meters (42.0 meters true thickness) averaging 0.284 g/t
Au, 4.9 g/t Ag, 0.36% Pb and 1.07% Zn including 11.5 meters (6.3 meters
true thickness) averaging 1.21 g/t Au, 11.5 g/t Ag, 0.98% Pb and 2.29% Zn.
To date, a total of 4,850 meters have been completed in the phase
one drill program. The mineralized shear zone has been traced for a
total of 500 meters along its strike length and to a maximum depth of 400
meters from surface. In addition, a surface trench located 425 meters
north of Oroco�s northernmost drill hole (see press release dated September
5, 2008) has exposed the mineralized zone over a 36.3 meter true width.
Hole CP019 is currently being drilled and assays are awaited for
holes CP012 to CP018. Please refer to Oroco�s website for the
location of the completed holes on a longitudinal section http://www.orocoresourcecorp.com/images/Longitudinal-Section.jpg.
The following table is a summary of the significant assays received
from holes CP008 to CP011. Also included is a new calculation for CP003 that includes an
extension to the width of the mineralized zone that had not previously been
sampled.

The four new drill holes
reported in this release are outside of the area included in Morgain
Minerals� historical resource calculation and significantly enhance the
potential for a larger resource than that concluded from Morgain�s work.
Also of great importance is the addition of copper and molybdenum to
the metallogeny. Although the intersections containing high grade
copper and molybdenum are relatively thin, the model of a deep epithermal
or mesothermal system is holding true.
Also significant is the
fact that CP011, the deepest hole on the property to date, intersected
sulphides including visible pyrite, galena and sphalerite indicating that
the oxide zone exists to a depth of approximately 350 meters from surface
and that higher base metal contents are present below the oxide zone.
CP019 is currently being
drilled and three other holes will be completed in the next few weeks,
which will conclude the phase 1 drill program. Trenching, mapping and
sampling are continuing on the surface trace of the mineralized zone.
At the completion of these programs and after all assays are received
and reviewed, the Company intends to commence a phase 2 drill program
including infill and step out drilling.
The Cerro Prieto
polymetallic project is located in Sonora State, Mexico and consists of
three mineral concessions totaling 2,508 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 program (6,000 meters in 22
holes) 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.
Qualified Person
Kenneth R. Thorsen,
B.Sc., P. Geo., is a director of the company and is a 'qualified person'
for the purposes of National Instrument 43-101 Standards of Disclosure for
Mineral Properties of the Canadian Securities Administrators and has
verified the data (including sampling, analytical and test data) and
prepared or supervised the preparation of the information contained in this
news release.
Quality
Assurance & Control
The Company has
implemented a quality assurance and control (QA/QC) program to ensure sampling
and analysis of all exploration work is conducted in accordance with the
best possible practices. Split core is transported to the ALS Chemex
laboratory in Hermosillo where it is crushed and pulverized, with pulps
sent to the ALS Chemex laboratory in Vancouver, B.C. for assaying.
The other half of the core is retained for future assay verification.
The QA/QC policy includes the chain of custody monitoring, insertion of
blanks, standards and duplicates in the initial samples submitted.
The laboratory provides an additional internal control program.
