Cascadero Copper Corporation: Las Cuevas Drill Program Completed

Marketwired Canada
Cascadero Copper's (TSX VENTURE:CCD) 50% owned subsidiary Salta Exploraciones SA
(Salta), completed a five core hole program totaling 785.4 metres of a planned
seven core hole 1,000 metre program on the Discovery Zone at Las Cuevas. The
program was shortened due to ground conditions. Management believes that five
completed holes are a representative sample of the Discovery Zone. The five
drill core intervals are directly below surface trenches, up to 100 metres in
width, that have variable grades of gold and silver. The distance between the
furthest south core hole to the furthest north core hole is about 250 metres.
Alteration includes limonite, sericite, silica, pyrite and quartz in stock work
and veinlets. The style of mineralization is principally mesothermal with minor
epithermal textures. The oxidized material in drill core consists of sandstone,
siltstone and interbedded shale.

The Las Cuevas Discovery Zone is the northern most of two gold bearing outcrops
controlled by a regional fault system. A second gold bearing outcrop, the Hilda
Zone, is 1,200 metres to the south. Several gold bearing outcropping veins and
mineralized zones occur between Discovery and Hilda, along the ridge that
outlines the fault. This suggests that Las Cuevas may host a larger gold bearing
system that may be contiguous between the Discovery and Hilda zones.
Infrastructure at Las Cuevas is excellent as the property is road accessible; a
high-voltage power line to Chile passes through the property's southern extreme;
the natural gas line to Pocitos is within 6kms; and, the railway to Antofagasta,
Chile is approximately 8 kms to the north. There is a small mining supportive
indigenous community close by with qualified local field support personnel. The
property is between 3,000 to 3,600 metres elevation and can be worked year
round.
The area is part of the south eastern extension of the Colama-Olacapato-El Toro
(COT) mega transverse structure, which generates structural compression and
dilation zones, called pull-apart basins, that provide the faults and fractures
that permit deposition of precious and base metal hydrothermal fluids in
surrounding host rocks. The COT lineament has generated great mineralized areas
such as Chuquicamata and El Laco in Chile, Taca Taca, El Oculto, El Quevar,
Concordia, Pancho Arias, Las Burras, Incahuasi Las Cuevas and several other
mineral deposits and showings in north western Argentina.
The Company is assaying the entire one-half of each drill hole in one-metre
intervals where possible due to extensive fracturing and broken rock. The
meta-sediment encountered at the end of LC11-03, -04 and -05 provided the best
core recovery. The meta-sediment has quartz in veins and veinlets as principal
alteration. These intervals are in for assay. The Company intends to release
assays after all results are received, compiled and interpreted. The samples are
shipped to ACME Labs Mendoza, Argentina for preparation and fire assaying for
gold and silver.
ABOUT CASCADERO COPPER
Cascadero Copper is an integrated prospecting and mineral exploration business.
The Company has offices in North Vancouver, BC, Sudbury, Ontario and Salta City
in the province of Salta, Argentina. The Company generates, acquires and
explores mineral properties. The Company has several copper-gold porphyry
prospects in the Toodoggone region of British Columbia, a 100% interest in 22
volcanic and intrusive hosted gold properties in the Sudbury, Swayze and Timmins
camps of Ontario and holds a 50% interest in a 46 property portfolio in north
western Argentina.
Exploration is currently active in Ontario and Argentina. A 2,448 metre core
drilling program was completed July 2001 on the MEX copper-gold porphyry in
British Columbia.
Cascadero's commodity focus is gold, silver and base metals hosted in
large-scale mineral systems. In 2011 and 2012, Cascadero and Salta plan to drill
test a total of four copper-gold porphyry systems and four large-scale sediment
hosted gold and silver-rich polymetalic systems and two sediment hosted
gold-silver showings.
