GLOBAL COPPER GOLD EXPLORATION

SEPTEMBER 2, 2003

High-Grade Enriched Copper Zone Discovered at Mirador

 With pre-feasibility work continuing, Corriente is currently carrying out a review to investigate the economics of contract mining, copper concentrate transport and port operations for the Mirador project. Corriente is also evaluating several funding options for the subsequent feasibility study and is looking to complete this step shortly.   

Corriente foresees the Mirador project as the key starter project for the phased development of the entire Corriente Copper Belt in Ecuador. Such a sequential development plan would maximize the potential to fund expansion from cash flow and minimize the amount of funds required from the market or lenders. In addition to this scoping study, Sumitomo Metal and Mining Co. of Japan recently completed a positive metallurgical study at Mirador. The Corriente Copper Belt currently is known to contain three deposits (Mirador, San Carlos, Panantza), with announced geological resources of approximately 600 Million tonnes at a grade of 0.8% copper plus gold and molybdenum credits. The Belt also contains numerous undrilled targets, which have had preliminary field investigation but have not been the subject of follow-up drill programs.  

Corriente Recources Inc. is a Canadian based junior resource exploration and development company specializing in copper and copper-gold opportunities. The company's main focus is the development of the Corriente Copper Belt in Ecuador. In addition, Corriente has a global exploration alliance with BHP Billiton, one of the worlds largest mining companies. Corriente continues to review advanced copper and copper-gold exploration projects through this alliance.
