CORE DRILLING PROGRAM COMPLETED ON MEX COPPER GOLD PORPHYRY PROSPECT,TOODOGGONE REGION BRITISH COLUMBIA

Wed Aug 3, 2011
Gold Fields Toodoggone Exploration Corporation ("Gold Fields"), a member of the Gold Fields Limited group of companies has completed its drill program on Cascadero Copper Corporation's ("Cascadero") 100% owned MEX copper gold porphyry prospect. The property is located in the Toodoggone region in north-central British Columbia, which is about 550 km north of Prince George. The MEX prospect is approximately 16 km northeast of Northgate's Kemess North copper-gold deposit.

The program consisted of seven drill holes for an aggregate of 2,448 metres of NQ core. The drill holes encountered a mineralized quartz monzonite unit, which includes magnetite with lesser amounts of pyrite and chalcopyrite. Alteration also includes an interpreted sericite- chlorite overprint. The drill program partially tested a zone that is approximately 500 metres northeast-southwest by 900 metres northwest-southeast.

Gold Fields prepared and shipped 1,025 samples for assay to ALS Minerals in North Vancouver, BC. Results are expected in five weeks time.

On March 6th 2009, Cascadero signed an Option and Joint Venture Exploration Agreement (the "Option Agreement") with Gold Fields. Pursuant to the Option Agreement Gold Fields can earn a 51% interest in Cascadero's Toodoggone Project a by spending at least C$5 million over an initial three year option period. Gold Fields can earn a further 24% interest by completing a feasibility study or sole funding a further C$15 million in expenditure. Gold Fields has incurred about C$4 million in expenditure to date.
