About Rio Cristal Resources Corporation

Rio Cristal Resources is a Canadian corporation focused on the discovery and further development of gold, copper and zinc deposits in Peru.

Outstanding initial drilling results confirm that the project is within an important emerging Mississippi Valley-type zinc district.

The Company is also exploring its Condor gold project near Nazca, Peru. Recent assays of a 300 kilo bulk surface sample averaged 3.25 grams of gold per tonne (see news release dated March 15, 2010). Drilling is expected to begin in August pending receipt of necessary permits.  In addition, the Company is evaluating the acquisition of a copper oxide property with significant potential for low-cost, leachable copper resources.
