ARGENTINE SILVER - GOLD POLYMETALIC SYSTEMS
OCULTO MINERAL DISTRICT
SSC ZONE HIGHLIGHT
OUTCROP ROCK SAMPLE ASSAYS 1,085 g/t (34.9 oz/t) Silver

(CCD: TSXV)
The Company received assays from seventy-one (71) rock samples from the SSC Zone on the Oculto prospect in north western Argentina that average 60.7 g/t silver (1.95 ounces) with anomalous values in gold, lead and antimony. Eight (8) of the 71 samples returned assays >100 g/t silver. The over limit assays were 151, 188, 212, 522, 575, 575, 636 and 1,085 g/t silver as displayed in TABLE ONE below.

Over Limit Silver Assays with Gold and Base Metal Values
SSC Zone
| Silver g/t | Gold g/t | Lead % | Antimony % |
| 1,065 | 0.013 | 0.16 | 0.04 |
| 636 | 0.005 | 0.10 | 0.08 |
| 575 | 0.042 | 0.39 | 0.05 |
| 575 | 0.081 | 0.37 | 0.03 |
| 522 | 0.672 | 0.15 | 0.03 |
| 212 | 0.411 | 0.08 | 0.12 |
| 188 | 0.091 | 3.21 | 0.03 |
| 151 | 0.063 | 0.18 | 0.02 |
The high-silver values are associated with limonitic sediments with greyish silica veinlets and stock work, which variably occur along the entire length of the outcropping structure. The SSC Zone is now a high-priority for further exploration. The importance of these exceptional silver values provides evidence that the Oculto mineral system can produce very high-grades within lower grade large-scale alteration systems. This information and the location of the high-grade silver samples enables the Company to focus its next phase of exploration with an excavator trenching program, mapping and a more sampling. This will likely lead to focused geophysical surveys that will assist in positioning drill collar locations.
The SSC Zone is the largest continuous outcropping sedimentary system in the Oculto Mineral District. It is at least 3,600 metres NW-SE and up to 1,000 metres wide. The most prominent outcrops consist of silicified conglomerate. The host sediments include argillic, limonitic and silicified siltstone and sandstone. The SSC zone is underexplored and there are no historic drill holes.
Cascadero Copper's 50% owned subsidiary Salta Exploraciones (Salta) holds a 100% interest in 31,024 hectares that includes the majority of the most prospective geology in the 70 km2 high-sulphidation sediment hosted epithermal Ag-Au 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, including Pancho Arias, Las Burras, Incahuasi, Las Cuevas, Santa Rosa, Concordia, El Quevar, El Oculto, Taca Taca, in Argentina and El Laco and Chuquicamata in Chile.
The SSC Zone is about 3.0 kms north of the Luc Carrill Zone that Cascadero announced in a news release on April 11th, 2011.
Salta is planning a US$600,000 exploration program that includes property-scale mapping, geological cross sections, geochemistry, trenching and ground based geophysics followed by core drilling on selected targets.
The property has exceptional infrastructure. The Argentine national highway, a 500 Kv high-tension power line, and a natural gas pipeline are located on property. Importantly, the railway to the Pacific Ocean port of Antofagasta also passes through El Oculto.
The Company is pleased to have this highly prospective contiguous 31,024 hectare property under its control and believes the Oculto District has potential to host large-tonnage bulk mineable silver - gold - base metal 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.

ABOUT CASCADERO COPPER - SALTA EXPLORACIONES
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 showings.
