VANCOUVER, BRITISH COLUMBIA, Sep 28, 2011 (MARKETWIRE via COMTEX) –Cascadero Copper’s /quotes/zigman/364470 CA:CCD -13.33% 50% owned subsidiary SaltaExploraciones SA (Salta), completed a five core hole program totaling785.4 metres of a planned seven core hole 1,000 metre program on theDiscovery Zone at Las Cuevas. The program was shortened due to groundconditions. Management believes that five completed holes are arepresentative sample of the Discovery Zone. The five drill coreintervals are directly below surface trenches, up to 100 metres inwidth, that have variable grades of gold and silver. The distancebetween the furthest south core hole to the furthest north core holeis about 250 metres. Alteration includes limonite, sericite, silica,pyrite and quartz in stock work and veinlets. The style ofmineralization is principally mesothermal with minor epithermaltextures. The oxidized material in drill core consists of sandstone,siltstone and interbedded shale.

A second gold bearingoutcrop, the Hilda Zone, is 1,200 metres to the south. Several goldbearing outcropping veins and mineralized zones occur betweenDiscovery and Hilda, along the ridge that outlines the fault. Thissuggests that Las Cuevas may host a larger gold bearing system thatmay be contiguous between the Discovery and Hilda zones. Infrastructure at Las Cuevas is excellent as the property is roadaccessible; a high-voltage power line to Chile passes through theproperty’s southern extreme; the natural gas line to Pocitos iswithin 6kms; and, the railway to Antofagasta, Chile is approximately8 kms to the north. There is a small mining supportive indigenouscommunity close by with qualified local field support personnel. Theproperty is between 3,000 to 3,600 metres elevation and can be workedyear round. The area is part of the south eastern extension of theColama-Olacapato-El Toro (COT) mega transverse structure, whichgenerates structural compression and dilation zones, calledpull-apart basins, that provide the faults and fractures that permitdeposition of precious and base metal hydrothermal fluids insurrounding host rocks. The COT lineament has generated greatmineralized areas such as Chuquicamata and El Laco in Chile, TacaTaca, El Oculto, El Quevar, Concordia, Pancho Arias, Las Burras,Incahuasi Las Cuevas and several other mineral deposits and showingsin north western Argentina. The Company is assaying the entire one-half of each drill hole inone-metre intervals where possible due to extensive fracturing andbroken rock. The meta-sediment encountered at the end of LC11-03, -04and -05 provided the best core recovery. The meta-sediment has quartzin veins and veinlets as principal alteration. These intervals are infor assay. The Company intends to release assays after all resultsare received, compiled and interpreted. The samples are shipped toACME Labs Mendoza, Argentina for preparation and fire assaying forgold and silver. ABOUT CASCADERO COPPER Cascadero Copper is an integrated prospecting and mineral explorationbusiness. The Company has offices in North Vancouver, BC, Sudbury,Ontario and Salta City in the province of Salta, Argentina. TheCompany generates, acquires and explores mineral properties. TheCompany has several copper-gold porphyry prospects in the Toodoggoneregion of British Columbia, a 100% interest in 22 volcanic andintrusive hosted gold properties in the Sudbury, Swayze and Timminscamps of Ontario and holds a 50% interest in a 46 property portfolioin north western Argentina. Exploration is currently active in Ontario and Argentina. A 2,448metre core drilling program was completed July 2001 on the MEXcopper-gold porphyry in British Columbia. Cascadero’s commodity focus is gold, silver and base metals hosted inlarge-scale mineral systems. In 2011 and 2012, Cascadero and Saltaplan to drill test a total of four copper-gold porphyry systems andfour large-scale sediment hosted gold and silver-rich polymetalicsystems and two sediment hosted gold-silver showings.
