Frontera Copper Board of Directors Recommends Rejection of Unsolicited Offer from Invecture Group

Toronto and Phoenix, AZ - December 18, 2008 - Frontera Copper Corporation (FCC:TSX, FCC.NT:TSX, FCC.NT.A:TSX) today announced that its Board of Directors has unanimously recommended that shareholders REJECT the unsolicited offer from Invecture Group, S.A. de C.V. ("Invecture"), to purchase all of the outstanding common shares of the Company for Cdn$0.59 per share (the "Offer").

In its Directors' Circular being filed today on SEDAR and mailed to shareholders, the Board strongly recommended that all Frontera shareholders REJECT the Offer and not tender their shares for the following reasons:

Superior proposals delivering greater value for shareholders may emerge
The Offer undervalues Frontera's assets
The timing of the Offer is opportunistic given the recent decline in the price of copper and in the price of Frontera shares
The Offer is highly conditional and discretionary
There is uncertainty with respect to Invecture's intentions
The Company's financial advisor has provided an opinion that the consideration offered pursuant to the Offer is inadequate, from a financial point of view, to Frontera shareholders other than Invecture and its affiliates

As previously announced, RBC Capital Markets has been retained as the Company's financial advisor to assist in the examination and consideration of various corporate strategic alternatives, including the evaluation of all prospective purchase offers that may be received for the Company. The process of identifying and engaging other potential acquirers is currently well underway.

Shareholders are encouraged to read the Directors' Circular in its entirety and to carefully consider the reasons for the Board's recommendation. The Board wishes to reaffirm its commitment to ensuring that maximum value is achieved for shareholders of the Company.
