ENVIRONMENTAL PERMIT AND WATER USE PERMIT APPROVED
FOR MIRADOR PROJECT, ECUADOR

VANCOUVER, CANADA, July 20, 2009 – On March 17, 2009, Corriente Resources Inc. announced that all suspensions of field operations of the company were lifted. Continuation of our permitting activities at Mirador has led to approval by the Ministry of Environment of our updated Environmental Management Plan and by the Secretary of Water for our Water Use Permit. Securing these two key permits is an essential milestone for advanced operations to commence in the field.

Separately, negotiations are continuing with the selected party regarding the potential sale of the company, as last reported in the company’s news release dated June 9, 2009. Discussions are ongoing and management remains satisfied with the progress to date. Further comments or announcements will be made by the company as developments warrant. No assurance can be given that the negotiations will result in an agreement for any sale of the company.

ABOUT CORRIENTE
Corriente holds a 100% interest in four known copper and copper-gold porphyry deposits that are being strategically developed as the Mirador Project (which includes our Mirador Norte deposit) and the Panantza-San Carlos Project, for which NI 43-101 Technical Reports have been filed on SEDAR (www.sedar.com).

The company also holds 100% of concession interests covering approximately 430 square kilometres, in which six additional copper exploration targets have been identified. Taken together, the known project deposits and exploration targets represent a potential long-term district development opportunity for large-scale copper-gold mining in southeast Ecuador.
