Vancouver, B.C., April 14, 2010, Copper One Inc. ("Copper One"; TSX-V: CUO) is pleased to announce positive Phase I drilling results from its 100% owned Twin Peaks project in Arizona, a major copper producing region. The 2,572 meter reverse circulation (RC) drilling program consisted of 18 holes on a systematic 120 metre grid drill pattern. The drilling defined a relatively continuous copper oxide mineralized zone over a northwest trending area 800 metres long and 300 metres wide with thicknesses varying between 24 metres and 155 metres vertically. It is important to note that the copper oxide mineralization starts at surface. The zone is open to the northwest and southeast and appears to thicken to the southwest below a moderately dipping post mineral fault.
Significant assay intercepts are listed below using a cutoff grade of 0.05% Cu:
In addition, continuous surface channel sampling along five road cuts within the copper oxide zone demonstrated lateral continuity of copper grades. Continuous chip samples were collected on 1.5 meter intervals. Road cut channel sampling highlights include:
Copper One is evaluating the open-pit copper oxide potential at Twin Peaks that may be amenable to low cost SX-EW (solvent extraction-electrowinning) processing.
The Company conducted preliminary acid-soluble-copper assays on all the samples from the Twin Peaks drilling. Using a 0.05% acid-soluble-copper cutoff grade, the recovery by acid leach ranged between 54 and 77% of the total copper. Further metallurgical work is being planned.
"We are very pleased with the results of the first phase of drilling on the Twin Peaks property. We have defined a large volume of copper oxide mineralization and identified potential to grow it", said Alan Edwards, President and CEO of Copper One Inc. "We look forward to fully evaluating these results and testing the next round of targets on our way to building a resource."
Drilling, channel sampling and surface mapping indicate that the copper oxide mineralization at Twin Peaks is hosted in an oxidized potassic altered quartz monzonite. Copper oxide mineralization consists primarily of chrysocolla in stockwork veinlets and disseminations. The association of fracture controlled copper oxides and lack of calcite within quartz monzonite typically provide favorable leaching characteristics. The quartz monzonite is of Laramide age; similar intrusives host copper oxide and porphyry copper deposits throughout the southwestern United States. There are numerous additional untested targets on the property, associated with copper oxide outcrops and copper soil anomalies.
The Company has employed rigorous chain of custody and QA/QC procedures for the Twin Peaks RC sampling. Samples were transported by the supervising geologist at the end of each shift to a secure storage unit. Skyline Lab personnel periodically picked up samples from the storage unit. Copper One makes use of analytical control samples (standards and blanks) inserted throughout the sample sequence. The performance of the analytical control samples is recorded and measured against accepted values to monitor lab performance. Skyline Labs is accredited to ISO 17025:2005 by the American Association for Laboratory Accreditation for sample preparation and various assay procedures. Copper values for all samples were obtained from Skyline's SOP 401 three acid AAS package. The copper values from this analytical package are considered to be near-total for most rocks.
About Copper One Inc.
Copper One Inc. holds a significant portfolio of copper properties in the prolific copper- producing regions of Arizona and New Mexico. This area hosts some of the world's largest and most profitable copper mines and yields over 10% of the world's copper production. Copper One Inc. is focused on the discovery of copper resources which are suitable for leaching. Lone Mountain, the company's feature property, is within sight of the large Tyrone and Chino porphyry copper mines operated by Freeport-McMoRan. Five core holes have been completed at Lone Mountain in 2010. Results from two holes were recently reported; the remaining assays are pending. Photographs of select core intercepts are posted on Copper One's website.
