Rock Chip Sample Assays 2.5 g/t Gold, 7.6 ounces Silver, 2.0% Lead

From Extensive OCD Sediment Hosted System

JUNE 8th 2011


The Company received assays from twelve (12) rock chip samples from the OCD Zone on the Oculto property. The 12 samples have an average of 0.73 g/t gold, 39.0 g/t silver and 0.61% lead.. In addition to the high lead values, the samples also contain a highly-anomalous base metal suite with bismuth (0.03%), copper (0.05%), antimony (0.03%) and zinc (0.05%). The chip samples were taken from an area of historic work and cover an outcrop area that extends 250 by 450 metres, which is the northern portion of a 250 metre by 2,500 metre outcropping argillic alteration envelope. The mineralization consists of limonitic-quartz veins and stock work that is hosted in silicified sediments consisting of interbedded sandstone, siltstone, pebble conglomerate and dacite tuff.

Cascadero Copper's 50% owned subsidiary Salta Exploraciones (Salta) holds a 100% interest in the El Oculto property (1,800 hectares) in Jujuy Province, northwestern Argentina. The OCD zone is part of El Oculto, which is part of a 70 km2 high-sulphidation sediment hosted epithermal Au-Ag polymetalic mineralized sedimentary basin situated within the Colama-Olacapato-El Toro (COT) fault system. The COT is a northwest trending transverse zone that controls the location of several large mineral systems in northwestern Chile and Argentina that includes Pancho Arias, Concordia, El Quevar, El Oculto, Taca Taca, El Laco and Chuquicamata. Salta controls the majority of the prospective geology in the 70 km2 Oculto sedimentary basin in Argentina.

The OCD Zone is about 5.2 kms northwest of the Luc Carrill Zone that Cascadero reported assays for in a news release on April 11th, 2011.

Salta is planning a US$600,000 exploration program that includes property-scale mapping, geochemistry, trenching and ground based geophysics followed by core drilling where warranted on selected targets.

The property has exceptional infrastructure. The Argentine national highway, a high-tension power line, and a natural gas pipeline all pass through the property. Importantly, the railway to the Pacific Ocean port of Antofagasta also passes through El Oculto.

The Company is pleased to have this exceptional property under its control and believes the property has the potential to host large-tonnage bulk mineable gold- and silver-rich polymetalic deposits.

Assays were done by ACME Analytical of Vancouver BC. This report was reviewed and the technical contents approved by Dr. George Gale, PhD., PEng., who is the Qualified Person for the Company's Argentine properties.

The Companies are integrated prospecting and mineral exploration businesses 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 focus is on large-scale open pit mineral systems such as copper-gold porphyry prospects in the Toodoggone region of British Columbia, volcanic and intrusive hosted gold properties in the Sudbury, Swayze and Timmins gold camps of Ontario and copper-moly-gold porphyry prospects and gold-silver, base metal sediment hosted mineral systems in north western Argentina.

Exploration is currently active in Ontario and Argentina and will commence in June, 2011 in British Columbia.

Cascadero's commodity focus is gold, silver and base metals. In 2011, Cascadero and its joint venture partners plan to drill test a total of four copper-gold porphyry systems and two sediment hosted gold-silver systems.
