PIEDRAS VERDES

Frontera Copper Corp is seeking to extend the payment of interest on its Notes such that these payments would be made over the period of June through August 2009. Such a change is being submitted to the Note holders for approval through an Extraordinary Resolution dated June 10, 2009. Frontera has been advised by its’ mining contractor PEAL S.A. d CV that they were going to sell their mining equipment previously being used at the Piedras Verdes Mine under its contract with Frontera. Frontera Management entered into discussions with its shareholder and with PEAL to determine if an alternative solution could be found to secure the mining equipment and find sufficient funding to allow the restart of mining. The company is close to reaching an agreement with PEAL that will secure this equipment and substantially improve its chances of restarting mining. This agreement will require the assistance of a third party. This will essentially consume most of the funds available within Frontera to secure this equipment and obtain a commitment to restart mining under the terms of the existing PEAL Contract. The Frontera Board believes that it is only through the restart of operations that the viability of the company can be maintained.

Announced that as a result of slower than expected rates of copper recoveries, management engaged an independent consultant to conduct a review of recovery rates for ores placed on the leach pads prior to the end of the second quarter of 2008. Conclusions drawn from this review, which were based upon actual operating results to date, suggest that the 37.4 million tonnes of ore at an average grade of 0.34%, which were primarily mined from the western zone prior to the end of the second quarter of 2008, may achieve an ultimate recovery of 52.5%, compared to the previous estimate of 62.5% to 61.9%. On Nov11/08, announced that in response to the recent downturn in copper prices, mining activities at Piedras Verdes Operations will be temporarily suspended.

Frontera Copper suspended mining at its Piedras Verdes mine in Mexico in response to the recent downturn in copper prices. Copper production will continue on a gradually declining basis while leaching operations will proceed on an uninterrupted basis to recover copper from ores previously placed on the leach pads.
