Rio Cristal Resources Corporation (TSX VENTURE: RCZ)(BVL: RCZ) ("Rio Cristal" or the "Company") today announced that it has entered into an agreement with SinoLatin Capital Incorporated to act as the Company's financial adviser in China.

Thomas Findley, President and CEO of Rio Cristal, said, "China is the world's largest consumer of zinc, consumption levels are growing each year and China imports approximately 50% of the zinc feed needed for its refineries. Rio Cristal is actively looking for a joint venture partner for our flagship Bongara zinc project in Amazonas, Peru and it makes sense that we have contact with potential Chinese partners on a regular basis. I am very pleased to have entered into our agreement with SinoLatin Capital, a company that can help us maintain an active presence in China as it acts as our adviser."

Headquartered in Shanghai, SinoLatin Capital is the first financial advisory firm focused exclusively on cross-border transactions between China and Latin America. The firm specializes in the natural resource transactions, with a particular emphasis on the mining sector. "China's demand for resources such as zinc continues to propel global production, and Rio Cristal is strongly positioned to play an important role in meeting this surge in demand. We are grateful for Rio Cristal's confidence in our China experience and presence in helping the Company forge new Chinese partnerships," said Erik Bethel, Managing Partner of SinoLatin Capital.

The terms of the Rio Cristal Resources agreement with SinoLatin Capital are subject to approval by the Toronto Stock Exchange (TSX).

About Rio Cristal Resources Corporation

Rio Cristal Resources is a Canadian corporation focused on the discovery and further development of zinc, copper and gold deposits in Peru. The Company's most advanced exploration project is the 18,000 hectare Bongara zinc claim block located in northern Peru. An initial 4,200 meter drilling program confirmed that the project is within an important emerging Mississippi Valley-type zinc district. In 2011, Rio Cristal has begun a 6,000 meter drill campaign in with the objectives of confirming a zinc oxide resource and discovering deeper sulfide zinc ores. Additionally, the Company is exploring methods of treating its zinc oxides so that it may make a production decision quickly and efficiently.

The Company is also conducting surface exploration at its La Cumbre copper oxide project near Chala, Peru. The process of obtaining drilling permits is underway and drilling is expected to begin in May, 2011 with an objective of completing 2,000 meters. Rio Cristal's preliminary review of La Cumbre indicates potential for bulk-mineable copper oxide mineralization grading in excess of 2% copper. Additionally, there is potential for copper sulfide mineralization as the project is located within a very prospective belt hosting significant iron oxide copper deposits. Extensive recent underground workings indicate a possible resource located at surface which could be rapidly quantified with potential for extending mineralization laterally and at depth.

The Company's shares are listed on the Toronto Stock Exchange, Venture Segment and the Bolsa de Valores de Lima (Lima Stock Exchange).
