- An increase of 49% in the Measured & Indicated copper resources to 1.06 billion pounds; and
- An increase of 17% in the Inferred copper resource, to 329 million pounds; also at a 0.10% copper cut-off.
The updated mineral resource estimate incorporates results from 42,418 feet (12,932 meters) of drilling following a significant land acquisition from Allied Nevada Gold Corp. in 2011. The study updates a previous mineral resource estimate in the 2010 NI 43-101 Technical Report Pre-feasibility Study Update for the Contact Copper Project, Elko County, Nevada, USA. The details of updated mineral resource estimate are provided in the accompanying tables.
"The substantial increase in copper resources at our Contact Copper Project validates the work we have done in property acquisition and drilling," commented Arnold Armstrong, President & CEO of Enexco. "We are very pleased with the updated resource figures and the progress we have made in advancing the project to a feasibility study. Our drill programs have produced steady and significant increases in the resources at Contact since 2007, and we still have exploration targets on the property to test by drilling."

| Notes: Mineral Resources have been classified according to "CIM Standards on Mineral Resources and Reserves: Definitions and Guidelines" (December 2005). Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of Mineral Resources will be converted into Mineral Reserves. Mineral Resources cited are global totals. It cannot be assumed that all or any part of an Inferred Resource will be upgraded to an Indicated Resource, or that an Indicated Mineral Resource will be upgraded to a Measured Resource, as a result of continued exploration. Cut-offs used are not based on specific economic conditions and are for comparison only. Mineral resource tonnages and contained metal quantities have been rounded to reflect accuracy of the estimate and the numbers may not sum due to rounding. |

The copper mineralization at the Contact Copper Project is comprised of multiple high grade veins within an envelope of lower grade mineralization within granodiorite. A single stage indicator approach was selected to model high grade zones. Copper grades were estimated from the drill hole data base, with assays capped at 10% Cu, using an inverse distance squared (ID-2) algorithm and dynamic anisotropy derived from geostatistical analysis. The resource was categorized into measured, indicated and inferred categories based on cumulative frequency distribution of estimation variance of the resulting block estimates. The mineral resources are global estimates and are unconstrained within the block model for the resources estimate.
The updated estimate uses results from 42,418 feet (12,932 meters) of drilling in 82 holes which commenced following the acquisition of 8,400 acres of adjoining mining claims in the district from Allied Nevada Gold Corp in 2011. The updated resource estimate is based on a database that now consists of 254,998 feet (77,743 meters) of drilling in 329 core and reverse circulation drill holes.
A NI 43-101-compliant Technical Report detailing the Updated Resource Estimate will be filed within 45 days of the date of this release. The report will be available at www.sedar.com. This report will supersede the PFS2010 and will not be updating the sections related to an advanced mineral exploration project. Enexco is currently working towards a feasibility study for the Contact Copper Project.
