COPPER-GOLD-BASE METAL SYSTEM
SALTA PROVINCE NORTH WESTERN ARGENTINA
APRIL 26th 2011
Cascadero Copper's 50% owned subsidiary Salta Exploraciones SA (Salta) has initiated a 1,750 metre drill program consisting of five (5) 350-metre NQ boreholes. Las Burras is 100% owned by Salta and is one of four porphyry systems in the Pancho Arias Mineral District, which is located in the western portion of the of the Colama-Olacapato-El Toro (COT) northwest trending transverse fault zone. The COT is a major crustal suture that controls the location of several large mineral systems in north western Chile (Chuquicamata, El Laco) and in Argentina (Taca Taca, Oculto, Concordia, Pancho Arias, Incahuasi, Ojo Negro). The drill program is fully funded.
Work by Salta consisted of geological mapping, petrography, IP/Res/Mag geophysics, MMI geochemistry, 2,300 metres of surface trenching and over 420 assays. Compilation of the data layers strongly supports the presence of an underlying mineralized system.
The size of the system is approximately 1,600 metres east west by 2,000 metres north south. The IP data suggests the system is open at 500 metres below surface. The trenches outlined a large area of argillic alteration with good gold values, extensive fracturing and some secondary copper showings. Additionally, a significant zone of leached-cap alteration is present on the western portion of the property. This is the location of the first core hole, LB11-01, which is underway. The property was not subject to a prior drill program.
The property has exceptional infrastructure. The Argentine National Highway #51, the high-tension power line and the natural gas pipelines to northern Chile are within 15 kilometers south of the property. Importantly, the railway to the Pacific Ocean port of Antofagasta passes through the southern part of the claims. Antofagasta is about 625 kilometres by rail west of Las Burras.
Las Burras is also located in a similar geological setting as two other Argentine copper-gold porphyry deposits: Alumbrera is in production (850 million tonnes) and Agua Rica is in the feasibility stage (800 million tonnes). Both deposits are located about 225 kilometres to the south of Las Burras.
Las Burras occurs in the Diego de Almagro multiphase magmatic complex and Alumbrera and Agua Rica are in the Farallon Negro multiphase magmatic complex. All three systems are of similar geologic age, which is Middle to Upper Miocene. Alumbrera, Agua Rica and the Pancho Arias Mineral District are within a north-west trending high-potassium calc-alkaline belt. The Alumbrera magmatic host rocks are compositions of an andesite-dacite-rhyolite suite, while Las Burras is composed of a diorite-granodiorite-monzogranite suite.
The Company is pleased to have this property in its portfolio and believes it has potential to host a large-tonnage bulk mineable gold-silver base metal deposit.

ABOUT CASCADERO COPPER
Cascadero is an integrated prospecting and mineral exploration business with offices in North Vancouver, BC, Sudbury, Ontario and Salta City in the province of Salta, Argentina. The Company generates, acquires and explores mineral properties in these three areas. The Company has several copper-gold porphyry prospects in the Toodoggone region of British Columbia, 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 and exploration will commence in June, 2011 in BC.
Cascadero's commodity focus is gold, silver and copper hosted in large-scale mineral systems. In 2011 and 2012, Cascadero plans to drill test a total of four copper-gold porphyry systems. In addition, Salta intends to drill four large-scale sediment hosted gold and silver-rich polymetalic systems and two sediment hosted gold-silver showings.
