Initial results from the current round of drilling at Mirador have defined an edge to the deposit to the east and south. Results have been received from the first 13 holes drilled in this phase of work. Of these holes eight are outside the area of the main copper mineralization Mineralization The process by which the body uses minerals to build bone structure.

Results from the holes within the main mineralized zone are shown on the table below. Holes M-3,23,28,34,37,39,40 and 43 (see map at www.corriente.com) are from outside the main mineralized zone and are available at the Website.

Drilling is continuing at Mirador with a series of recently completed deeper holes which are designed to test for higher grade mineralization extending to depth in the core of the deposit. Several holes will also be completed on the north and west side of the deposit to see if the main envelope of mineralization extends in that direction. This region is north of hole M-2 which averaged 0.68 % copper and 0.125 g/t gold (0.74% copper equivalent) for the entire 159 metres below the shallow leached capping. All drilling at Mirador is expected to be completed shortly and following receipt of assays, all outstanding results will be released.
