Frontera Copper Corporation - Home Page

Frontera Copper is a mining and exploration company whose principal activity is the production, through its subsidiaries, of copper cathode from the Piedras Verdes run-of-mine, heap leach, SX-EW copper operations in Sonora, Mexico. Based on the January 1, 2010 ore reserves and the estimated recoverable copper contained on the leach pad at December 31, 2009, approximately 726 million pounds of copper are projected to be produced during the remaining 15-year life of the project assuming certain economic conditions (primarily the price of copper). Existing resources and prospective exploration targets adjacent to the open-pit have the potential to extend the life of the mine.

At June 30, 2009, the leach pads at the Piedras Verdes Operations were estimated to contain 62 million pounds of recoverable copper based on the assumption of a re-start of mining activities so that the existing mineralized material can be subject to additional leaching cycles when new material is added to the pad. During the temporary suspension of mining activities, the Company expects to continue to produce copper cathode through the ongoing circulation of acidified solutions in the leach pads for as long as the operation continues to generate positive cash flows. The Company believes that as a result of these actions it will be better prepared to resume mining activities if and when copper prices return to levels that justify resumption of mining activities and if it is able to raise the funds necessary in order to do so. Management has reviewed the actual recoveries from the leach pads and in order to increase its confidence in the 62 million pound estimate has retained the services of a major independent engineering company to provide an additional independent assessment of the recoverable copper. This assessment is expected to be completed over the next few months.

Frontera Copper's common shares have been de-listed. Two series of debentures are listed and trade on the Toronto Stock Exchange under the symbols FCC.NT and FCC.NT.A, respectively.
