EXPLORATION SUMMARY - Toodoggone District, British Columbia 2005 to 2008

This press release summarizes the exploration work carried out by Cascadero Copper Corporation (the "Company") in 2005, 2006, and 2007 on its Toodoggone mineral claims. The Company did not conduct any exploration on the Toodoggone claims in 2008. On March 3rd, 2009 Cascadero signed an Option and Joint Venture Agreement with Gold Fields Toodoggone Exploration Corporation, a wholly owned subsidiary of Gold Fields Netherlands Services BV. Since that time, all exploration work on the claims has been conducted by Gold Fields Toodoggone Exploration Corporation pursuant to the Joint Venture Agreement.

2005

Diamond drilling was carried out on the FIN, MEX and RYAN CREEK properties. Significant drill intersections are listed in Tables One, Two and Three below. Geological mapping and sampling was carried out on the following Cascadero properties: Canyon Creek, Steel, Dry Pond, Pine North and 10K.

FIN PROSPECT

In 2005, the Company completed eight HQ/NTW core holes (F-05-01 to F-05-08) for a total of 1,892 metres. Drill access for the skid-mounted drill was attained by existing 1991 Cominco drill roads. Drill holes were located about 400 metres southwest of the 1991 Cominco percussion drill sites, targeted on historic Cominco geochemical and IP chargeability anomalies. Exploration work by Stealth Minerals in 2004 discovered copper and molybdenum surface mineralization hosted by intrusive rocks of the Geigerich pluton and crystal tuffs of the Toodoggone Formation. The best copper values from the 2005 drill program occurred in drill holes F-05-02 and F-05-06, which are located peripheral to the margin of the IP anomaly, indicating that future drilling should be located to the northwest. Significant copper and molybdenum values were attained from surface samples in the area northwest of the drill holes.

MEX PROSPECT

In 2005, the Company drilled four BQ/TW core holes (MX-05-01 to MX-05-04) for a total of 990 metres. The helicopter-supported program tested a 700 metre x 300 metre zone along the MEX ridge. Drill hole MX-05-01 tested a magnetic anomaly between the Giegerich pluton and MEX intrusions, including dykes. MX-05-01 is anomalous in gold values from 22.0 metres (360 ppb gold) to the end of the hole. MX-05-01 averaged 0.084% copper, 0.095% zinc and 0.45 g/tn gold over 123.43 metres from 22.0 metres to 145.43 metres. Included in this interval, from 136.0 metres to 145.43 metres, was a 9.4 metre interval that averaged 1.37 g/tn gold with 462 ppm copper and 334 ppm zinc. MX-05-01 was lost in a fault at 145.43 metres and was not followed up.

The MEX intrusions are overlain by intrusive breccia that cut Toodoggone tuffs. Surface oxidation extends down to at least 150 metres. Secondary copper (neotocite) occurs on fracture surfaces deeper in the system. Elevated gold values correlate with intense argillic alteration and high magnetic values. High copper values correlate with low magnetic values in altered rocks. Elevated gold values may be related to the roots of the hydrothermal breccia deeper in the system.

RYAN CREEK PROSPECT

At Ryan Creek, copper and zinc mineralization discovered in outcrop was followed up by soil geochemical and geophysical surveys, which defined a coincident 4,000 metres by 1,000 metres anomaly. The helicopter-supported program completed four BQ/TW core holes (RC-05-01 to RC-05-04) for a total of 918.25 metres. All inclined holes were drilled northeastward toward outcropping mineralization in Ryan Creek, and intersected monzonite porphyry. Toodoggone lithic crystal tuff was intersected in holes RC-05-01 and RC-05-04 above the monzonite. All drill holes encountered low copper with elevated zinc values and locally elevated gold values over significant widths. The positive geochemistry and lithologies in all holes suggests that these drill holes are located at the periphery of a porphyry deposit possibly related to the Nub Massif to the north or northeast.

2006

Geological mapping on MEX near drill hole MX-05-01 defined a zone of magnetite-veined volcanic tuff about 1,000 metres by 250 metres, which is estimated to be about 300 metres thick. Four drill holes were proposed for 2007 but none was drilled.

At PINE NORTH, a MMI geochemical line was sampled from Ryan Creek northeastward to PINE NORTH, a distance of 2,400 metres The MMI survey defined a Copper-gold anomaly interpreted to correspond to a body of porphyry-type mineralization possibly extending from PINE NORTH through Ryan Creek southwestward to PINE WEST.

2007

At PINE NORTH one NQ/TW core hole was drilled with helicopter support at -75º to azimuth 045º, to intersect a coincident MMI Cu-Au anomaly and an IP chargeability high. The hole intersected 67.1 metres of monzonite porphyry followed by 69.6 metres of quartz monzonite before terminating at 137.31 metres due to mechanical problems with the drill. The hole was planned to 350 metres in length.

Quartz-magnetite-pyrite veins were observed throughout the drill hole, copper assays ranged from 14 to 708 ppm, zinc from 37 to 91 ppm, silver values ranged from 0.2 ppm to 1.8 ppm and gold values were 0.03 g/t throughout. The planned five-hole program was deferred until another drill could be obtained.

A collaborative NSERC-CRD grant research project between UBC/Northgate Minerals Corporation/Stealth Minerals Ltd/Cascadero Copper Corporation was started in 2003 and ended in 2007. An airborne magnetic and radiometric survey was flown in conjunction, with GSC and BCGS support in 2003. Results were published by UBC in 2007. The research objectives included determination of porphyry-epithermal geological controls, identification of genetic links between the deposit types, construction of factual deposit models and a regional metallogenic model, and development of a predictive exploration model for the Toodoggone district.

This news release was prepared and approved for public distribution by the Company by Dr. Ken Dawson, P. Geo., and the Qualified Person for the Company's British Columbia properties. All assays included in this report were done by ECO TECH Laboratories Ltd., Kamloops BC.
