Cascadero Copper's 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 mesothermal. 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.
