Rock Chip Sample Assays 58.9 g/t silver
1.14% Lead from the NW Oculto Zone

JUNE 16th 2011


The Company received assays from eleven (11) rock chip samples from the North West Oculto "J" Zone on the Oculto property. The 11 samples average 15.1 g/t silver with highly anomalous gold and base metal credits equivalent to 31 g/t silver or ~1.0 oz/t silver.

The chip samples are from an area of altered sediments that measures 200 by 400 metres and is open in all directions and may be the extension of underlying and related sediment hosted mineralization.

The mineralization consists of limonitic-quartz veins in stockwork hosted in silicified sediments consisting of interbedded sandstone, siltstone, pebble conglomerate and dacite tuff, which is similar to several other mineralized zones in the 702 km Oculto property.
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 NW Oculto Zone is part of El Oculto, which is part of a 70 km2 high-sulphidation sediment hosted epithermal Au-Ag polymetalic 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 north western Chile and Argentina that includes Pancho Arias, Concordia, El Quevar, El Oculto, Aguas Calientes, Taca Taca, El Laco and Chuquicamata. Salta controls the majority of the prospective geology in the 70 km2 Oculto sedimentary basin in Argentina.

The NW Oculto is about 5.4 kms northwest of the Luc Carrill Zone and 200 metres west of the OCD Zone. Cascadero reported assays for each property on April 11th, 2011 and June 8th, 2011 respectively.

Salta is planning a US$600,000 exploration program that includes property-scale mapping, an eight km geological cross-section, geochemistry, trenching and ground based geophysics followed by core drilling where warranted.

The property has exceptional infrastructure. The Argentine National highway, a high-tension power line to northern Chile 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. Management believes the Oculto Mineral District has potential to host large-tonnage, bulk mineable gold-silver rich polymetalic deposits with aggregate silver equivalent grades comparable to Bear Creek's Coriani deposit in Peru (83 g/t Ag = 2.7 oz/t Ag) and Goldcorp's Penasquito deposit in Mexico (62 g/t Ag = 2.0 oz/t Ag).

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.
