Copper One Selects Priority Targets for Initial Drilling at Rivière Doré

May 26, 2011, Vancouver, BC: Copper One Inc. (TSXV: CUO) (the "Company" or "Copper One") is pleased to announce that target prioritization and drill target selection for the 2011 spring season has been completed for its Riviere Dore Cu-Ni joint venture project with Cartier Resources located southeast of Val d'Or, Quebec. Thirty-five (35) primary targets have been selected through property-wide modeled AeroTEM geophysics prioritized and selected in conjunction with field geology and geochemistry gathered by Cartier staff. Condor Consulting provided assistance in the target prioritization. The initial 35 primary targets were identified throughout the 60,500 hectares property which covers an 80 km long layered mafic intrusive complex. The targets were selected based on the occurrence of EM conductors, geomagnetics, till sampling, favorable geology, and rock sample anomalies that indicate potential for the local presence of Cu- Ni sulfide mineralization. These targets have been further prioritized for the spring 2011 core drilling program which will begin immediately following permitting, which is in process. The prioritization was based on inductive ratios of the EM conductor 3D modeling, surface geology, the surface geochemical anomaly density, location, and magnitude, in relationship to large geomagnetic features. Copper One anticipates drilling at least 15 of the targets and over 3,000 meters during the spring 2011 drilling campaign.

"We are excited to initiate the first phase of drilling on the vast Riviere Dore Cu-Ni property, which will not only follow up our mineralized channel samples, but further our understanding of the overall layered intrusive complex which contains over 75 kilometers of conductive targets. We anticipate development of many more drilling targets in the future" commented Alan Edwards, President and CEO of Copper One.
