Corriente Resources Inc.: Requested Changes to Technical Report to be Completed

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 16, 2006) - Corriente Resources Inc. (TSX:CTQ)(AMEX:ETQ) -


Following a review of our recently announced prospectus financing by the B.C. Securities Commission (BCSC), Corriente has requested Mine Development Associates (MDA) to make a change in its Technical Report on Corriente's Mirador project, which was filed on SEDAR on February 13, 2006. The Technical Report upgraded some of the resources at Mirador to reserves based on information from an independent feasibility study filed on Sedar May 13, 2005. The MDA report differs from the disclosure in Corriente's November 17, 2005 press release entitled "Mirador Mine Life Extended To 38 Years With New Optimization Results For Starter Copper Project" and its Annual Information Form dated March 24, 2006. The amended Technical Report, to be issued later this week by MDA, will reclassify the stated mineral reserves back to resources to match our other disclosure, and will include supporting information for the economic analyses announced in our November 17, 2005 release.

Corriente is moving towards construction of a starter operation at its Mirador copper-gold operation. Mirador is one of the few new, sizeable copper projects available for near-term production. Corriente controls a 100% interest in over 50,000 hectares located within the Corriente Copper Belt, Ecuador. The Belt currently contains three copper and copper-gold porphyry deposits, Mirador, Panantza and San Carlos, as well as the newly discovered Mirador Norte prospect. Additional exploration activities will be ongoing, as six additional copper and copper-gold exploration targets have been identified in the Corriente Copper Belt to date.
