Rio Cristal Resources Updates Its Condor Gold Property

VANCOUVER, BRITISH COLUMBIA and LIMA, PERU--(Marketwire - March 15, 2010) - Rio Cristal Resources Corporation (TSX VENTURE:RCZ) ("Rio Cristal" or the "Company") announces assay results from a campaign of bulk sampling on a mineralized quartzite bed known as Bench 5 within Zone 2 at its Condor gold property ("Condor") in southwest Peru.

Thomas Findley, President and CEO of Rio Cristal, said, "we are pleased to announce excellent results from our recently completed bulk sampling program at our Condor project. The gold assays from five bulk samples range from 1.12 to 6.82 grams per tonne ("g/t") and averages 3.25 g/t. Each bulk sample weighed between 57.5 kg and 68.5 kg and each was divided into 6 subsamples. The range of assays, as shown in Table 1, confirms the strong presence of surface gold mineralization within the Zone 2 prospect at Condor."

"The Company's goal at Condor is to continue defining and extending the limits of the outcropping gold-mineralized zones discovered to date. We expect to begin drilling the project this year."

The principal economic targets at Condor are gold-mineralized, potentially bulk-mineable zones hosted in sandstone and volcaniclastic sequences of Cretaceous to Lower Tertiary age. Bench 5 is a nearly vertical cliff face extending across strike for a distance of 50 meters and exposing about 10 meters of altered (silicified) quartzite stratigraphy. The five bulk samples were taken at approximately even intervals across strike over the 50 meters. Each of the five samples represents a panel 3 meters long (across strike) and about 2.2 meters high on the cliff face.
