News release, dated September 7, 2006, related to the Company's drilling results for its Panantza copper deposit. DOCUMENT 1 [CORRIENTE RESOURCES GRAPHIC OMITTED] ------------------------------------- | Disclosure statements as required | | by National Instrument 43-101 are | | available at our website | | www.corriente.com | ------------------------------------- "NEWS RELEASE" For Immediate Release September 07, 2006 --------------------- TSX: CTQ, AMEX: ETQ DRILLING EXTENDS PANANTZA COPPER MINERALIZATION, ECUADOR VANCOUVER, BRITISH COLUMBIA, September 07, 2006 - Corriente Resources Inc., announced today drilling results for its Panantza copper deposit. Further to our Panantza feasibility drilling news release of June 12, 2006, assays have been received from the most recent ten holes of this drilling program. Drilling continues to the south and further holes will be announced throughout the next few months. Current drilling results include hole PA039 with 17 metres of 1.31% copper in a secondary copper horizon overlying 399 metres of 0.66% copper. Panantza, which is located in southeast Ecuador approximately 40 km north of our Mirador project, has not been drilled since 2001. Previous inferred resources at Panantza total approximately 395 million tonnes grading 0.67% copper containing 5.8 billion pounds of copper. The deposit sits beside our San Carlos deposit that totals approximately 657 million tonnes grading 0.61% copper and containing 8.8 billion pounds of copper. Results from the previous drilling at Panantza included holes PA013 with 299 metres of 0.76% copper, hole PA012 with 269 metres of 0.97% copper, and PA017 with 64 metres of 1.29% secondary copper at the surface followed by 383m of 0.75% copper. The purpose of this drilling was to define the southern edge of Panantza's mineralization so that an updated resource calculation could be provided for a planned feasibility study. However, rather than delineate the edge of the Panantza deposit, the most recent results indicate the Panantza mineralization extends farther south than previously recognized. The southernmost holes drilled, PA033 and PA034, were both terminated in copper mineralization averaging over 0.8% Cu at the hole bottoms, at approximately 330 metres and 342 metres deep respectively. The Panantza drill plan has now been expanded to complete additional holes to follow this mineralization to the south. The geology from the new drilling is consistent with the existing model at Panantza, which is a conventional copper porphyry deposit hosted in granitic and porphyritic rocks. The copper mineralization is almost exclusively chalcopyrite with local horizons of secondary copper sulfide and oxide near the surface. The barren dike intersections in the table below are from a small 15-25 metre wide dike which crosses the area of this phase of drilling, but in general the amount of post-mineral dikes at Panantza is low. According to Ken Shannon CEO of Corriente, "Panantza-San Carlos represents a rare opportunity to capitalize on six years of community work, project engineering and management development that has been built around the nearby Mirador project. To be able to utilize that body of knowledge on a similar project such as Panantza-San Carlos will significantly aid in the project development process and at the same time allow us to take economic advantage of infrastructure that will be put in place for the Mirador mine." Results for the new holes are listed below and a map of the current round of drilling can be found at www.corriente.com.
