Vancouver, Canada and Lima, Peru, Marzo 22, 2010 - Rio Cristal Resources Corporation (TSXV:RCZ) ("RCZ" or the "Company") is pleased to announce completion of its previously announced incentive program (see news releases January 18 and February 23, 2010) for the early exercise of warrants issued in April 2009 (the "April 2009 Warrants").  A total of 14,260,094 shares were issued upon exercise of the April 2009 Warrants for aggregate proceeds of approximately $998,200 to the Company and a total of 7,130,047 new warrants were issued under the program.

Thomas Findley, President and CEO, said “This additional capital provides funding for exploration of our Condor gold project, maintenance of our Charlotte Bongara zinc project and general corporate purposes including funding to enable the Company to pursue additional copper and gold projects.”

Each warrantholder who exercised its April 2009 Warrants received one unit (in lieu of one common share) consisting of one common share and one-half of one new warrant (each whole new warrant, a "2010 Warrant").  Each 2010 Warrant allows the holder to acquire one common share of the capital of the Company at an exercise price of $0.12 until March 17, 2011.  The 2010 Warrants are subject to a four-month hold period ending July 18, 2010.  Holders of April 2009 Warrants who did not participate in the incentive program will be able to exercise their April 2009 Warrants for common shares of the Company on their original terms. 

The Company paid a 5% cash finder's fee in connection with the early exercise of certain of the April, 2009 Warrants.

The Company announces that it has also issued 200,000 shares pursuant to the terms of its option agreement in respect of the Condor property and has issued 669,697 common shares in payment of its US$50,000 payment required on March 15th under the agreement respecting the Charlotte Bongara zinc project.
