Cascadero Copper Corporation: Santa Rosa Drill Program on Tom Zone Completed

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 5, 2006) - Cascadero Copper Corporation (TSX VENTURE:CCD) ("Cascadero") has completed 13 NQ core holes on the Tom Zone at the Santa Rosa gold-silver prospect in north western Argentina. A total of 1,100.4 metres was completed. Core recovery ranged for a low of 89.1% to a high of 98.8% and averaged 94.8%. Drilling was conducted by Connors Argentina S.A. without material problems.

The core holes tested about 200 metres of strike length to a vertical depth of about 115 metres below surface, which is equivalent to 145 metres down dip.

The characteristics of the mineralization in surface outcrop and trenches are as follows:

- textures consist of multiple criss-crossing micro fractures and breccias;

- style of mineralization is transitional to mesothermal and gold dominant;

- alteration consists of limonite, goethite, sericite, hematite and silica;

- two lithologies are present - intrusive and sedimentary rocks;

- this material assays gold and silver in trenches and outcrops;

- the reader can refer to recent news releases where values are stated.

Similar looking altered, fractured and brecciated material occurs in the drill holes over variable thicknesses ranging from 15 to 55 metres.

The Tom Zone essentially strikes east to west and dips variably from -50 degrees to -60 degrees to the south. The azimuth of the drill holes is due north. The dip of the 13 core holes ranges between -45 degrees to -80 degrees. The true thickness of the mineralized interval in drill core is estimated at 95% to 100% for holes dipping from -45 degrees to -50 degrees (7 holes). The other six holes dip from -68 degrees to -80 degrees, which suggest that the true thickness of the mineralized interval in these core holes ranges from 70% to 80%.

The altered zone in drill holes is narrowest in the most south easterly core hole (PT-06-01) and thickens to the northwest (PT-06-13). It is believed that the altered zone is open to depth and also continues along strike under the pediment to the northwest of core hole PT-06-13. Excavator trenching along strike of PT-06-13 failed to reach bedrock.

Assays from the first 8 core holes are expected between June 12th and June 16th.

Sample preparation is conducted by Acme Analytical, Mendoza Argentina and assaying is conducted by Acme Analytical, Vancouver BC. All assays are 60 gram (two-assay tonne) fire assays with 34-element ICP. Field work is under the direction of Dave Kuran, P. Geo., who is the qualified person for Cascadero and its parent company Stealth Minerals Limited ( SML: TSXV).

Cascadero has an option to acquire a 51% interest in the Santa Rosa Property from Argentine Frontier Resources Inc. (AFRI) and its subsidiary Salta Exploraciones S.A. (SESA). Cascadero, Stealth, AFRI and SESA are related parties. Dr. Tom Richards, P. Geo. is the qualified person for AFRI and SESA.

By way of its share ownership in Cascadero and AFRI, Stealth Minerals holds a 39% equity interest in the property. Stealth Minerals also provides management and geological consulting services to Cascadero Copper.
