Abstract
Additionally, on November 17, 2005, Corriente issued a press release outlining an updated mineral resource estimate for the Mirador deposit which used a 0.40% Cu cutoff grade. To facilitate the resource comparison between the Mirador deposit and the nearby San Carlos and Panantza deposits (see www.corriente.com for related map), which were previously reported using a 0.65% Cu cutoff grade, Corriente has calculated inferred resource totals for Panantza and San Carlos at the 0.40% Cu cutoff grade.
The Panantza and San Carlos projects are both at an advanced development stage with preliminary metallurgical studies and scoping studies completed. The two projects share similar geological settings to the Mirador project and are expected to be developed using the same open pit mining, processing technology and infrastructure proposed for Mirador. Both Panantza and San Carlos are open for potential expansion of the known mineralized systems and drilling is planned for later in 2006 to formally update the geological model and resource assessment of both of these projects.
