and Invecture Group, S.A. de C.V.

Toronto and Phoenix, AZ - November 28, 2008 - Frontera Copper Corporation (FCC:TSX, FCC.NT:TSX, FCC.NT.A:TSX) today acknowledged the recent purchase of a 16 percent equity interest in the Company by Invecture Group, S.A. de C.V., a Mexican registered company ("Invecture"). Invecture has announced its intention to seek to acquire additional shares in the Company to the extent of at least the number of shares that would constitute legal control, provided such shares are available at an acceptable price. While a verbal dialog is currently underway between the Company and Invecture, the Company has received neither a formal offer nor entered into any agreements with Invecture pursuant to Invecture's stated intentions.

In light of the recent downturn in the copper market, the Board of Directors of Frontera Copper appointed a Finance Committee in October to evaluate the appropriate course of action to ensure maximum value for the stakeholders of the Company. The Company also intends to engage the services of a fiscal adviser in the near future to assist in the evaluation of any formal offers that may be received from Invecture or other interested parties with whom similar discussions are presently underway.
