CRCC-Tongguan Extends Bid for Corriente to April 28, 2010

  CRCC-Tongguan Investment Co., Ltd. (the "Offeror") announced today that it has extended to April 28, 2010 the expiry date of its February 1, 2010 offer (the "Offer") to acquire at a price of C$8.60 in cash per share all of the outstanding common shares of Corriente Resources Inc. (TSX: CTQ)(NYSE Amex: ETQ) ("Corriente"), including all shares that may be issued on the exercise of options granted under Corriente's stock option plan.

The obligation of the Offeror to take up the shares of Corriente deposited under the Offer is subject to the receipt of replacement titles for its mining concessions in Ecuador, Canadian competition and foreign investment approvals, and approvals required from the government of The People's Republic of China, in addition to other customary closing conditions as set out in the Offer documents, which are available on SEDAR.

Corriente is pleased to announce that the replacement titles required under Ecuador's 2009 Mining Law have been issued for each of Corriente's mining concessions, and that it believes that all Canadian competition and foreign investment approvals that are required for the completion of the Offer have been obtained. As set out in the press release of the Offeror issued earlier today, the Offeror believes that all regulatory approvals necessary to complete the Offer will be obtained prior to the expiry of the Offer.

The Offer, as extended, is scheduled to expire at 5:00 p.m. (Vancouver time) on Wednesday, April 28, 2010.

Kenneth R. Shannon, Chief Executive Officer
