PANANTZA COPPER RESOURCES CONTINUE TO GROW

Scoping Study For A Combined Panantza-San Carlos Project Advances

VANCOUVER, CANADA, June 20, 2007 – Corriente announces that an updated resource estimation has been completed for the company’s Panantza project in the Corriente Copper Belt in southeast Ecuador, which utilizes results from the most recent drilling program.

Using a 0.4% copper cut-off, the inferred copper resources at Panantza are now estimated at 463 million tonnes, containing approximately 6.7 billion pounds of copper at a grade of 0.66% copper. This estimate represents an increase of almost a billion pounds of contained copper in comparison to the company’s most recent disclosure for Panantza (please see current district copper totals in the table at the end of this release).

This increase is a result of additional mineralization that was discovered along the south margin of the Panantza deposit during the course of drilling. The next phase of drilling planned for Panantza is in the order of 24 holes, totaling over 7500 metres of coring. This drilling program will attempt to delineate the full extent of the Panantza copper mineralization that is still open to the south, north and at depth. The Qualified Person for this disclosure is John Drobe (P.Geo) of Corriente and the 43-101 Technical Report that details this work will be posted to SEDAR and the company’s website within 45 days.

The company is also well advanced on a Preliminary Assessment ("Scoping Study") for a combined Panantza and San Carlos project, given their close proximity (4 km apart) to each other. Corriente has engaged a team of engineering consultants, including Merit Consultants International Inc., Hoffert Processing Solutions Inc. and Knight Piésold Ltd. to complete this scoping work. The Scoping Study will consider a large central milling facility having a capacity of up to 90,000 tonnes per day and a project life of twenty years. An operation of this size and project length is estimated to process a combined copper resource from the Panantza and San Carlos deposits in excess of 600 Million tonnes, from an estimated total copper resource for these two deposits that is in excess of 1.1 billion inferred tonnes at a grade of 0.63% Cu. The milling process is forecast to produce an average of over 400,000,000 pounds of copper per year. This Scoping Study is planned to be completed later this summer and will be released as soon as it is available.

Management recognizes that the size of the combined Panantza – San Carlos project is better suited to the capabilities of a large integrated copper mining company in partnership with Corriente. Consequently, discussions have begun with several parties who are interested in a mining operation of large scale, which will enable the company to stay focused on development of the Mirador project as a priority.

Corriente CEO, Ken Shannon commented, "Advancing two large mining projects in one district presents a unique opportunity to significantly improve the economic stability of the region and would provide thousands of high-paying jobs as an alternative to their current subsistence economy. We remain committed to working with local communities, indigenous supporters and the government to continue to develop responsible mining in Ecuador and look forward to the resumption of our activities following a lifting of the suspension of field work at Mirador."

ABOUT CORRIENTE

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 Mirador Norte prospect currently under development. Additional exploration activities are ongoing, as six additional copper and copper-gold exploration targets have been identified in the Corriente Copper Belt to date.
