Provides Update on Operations

Toronto and Phoenix, AZ - December 22, 2008 - Frontera Copper Corporation (FCC:TSX, FCC.NT:TSX, FCC.NT.A:TSX) today provided an update on the Piedras Verdes operations.

Pursuant to the temporary suspension of mining activities announced in November, the Company and its mining contractor, Peal Mexico, S.A. de C.V., ("Peal") executed an amendment to their original mining contract. The amendment provides for the immediate release of approximately $1.7 million from an escrow account, funded when the contract was initially executed, to cover the costs associated with the demobilization of Peal's mining equipment from the Piedras Verdes operation. The addendum further states that if both parties agree to extend the contract, the term of such extension will be for a period equal to the duration of the suspension of mining activities. The Company and Peal also acknowledged that upon final payment of all outstanding invoices for work previously completed by Peal, no claims, demands or obligations remain between the two parties.

As previously announced, mining activities at Piedras Verdes were temporarily suspended in mid-November. Since then, leaching operations have proceeded on an uninterrupted basis to recover copper from ores previously placed on the leach pads. Based on actual and projected recovery rates achieved subsequent to the cessation of deliveries of fresh ore to the leach pads midway through the quarter, the Company estimates that copper production for the fourth quarter will total approximately 10 million pounds. Actual cash costs per pound of copper produced during the fourth quarter are expected to range from $1.85 to $1.95 per pound, excluding inventory accounting adjustments. Reported cash costs per pound, including inventory accounting adjustments, are expected to range from $1.55 to $1.65 per pound.

In November, the Company settled its copper hedges for the period December 2008 to March 2009. As a result, a payment of $6.9 million was received for the closure of hedges on 8.3 million pounds of copper, based on an average settlement price of $1.69 per pound compared to an average hedged price of $2.54 per pound. Combined with the settlement of October and November hedges as originally scheduled, net cash receipts attributable to the hedging program totaled $9.1 million for the fourth quarter. Currently, the Company has no remaining hedges outstanding.

The Company projects its year end 2008 cash balance at approximately $10 million, a decrease of about $13 million since September 30. This decrease is attributable to lower copper prices and the one-time costs associated with the temporary suspension of mining activities, partially offset by the cash receipts related to the settlement of copper hedges. The Company continues to anticipate the receipt of a refund of 2008 tax installments of approximately $7.2 million (at current exchange rates) in early 2009, since it is not expected to be in a cash taxable position in Mexico for the 2008 fiscal year.
