Frontera Copper Operations and Corporate Update

TORONTO, ONTARIO--(CCNMatthews - April 24, 2007) -

(All dollar amounts are expressed in United States currency unless otherwise noted)

Frontera Copper Corporation (TSX:FCC)(TSX:FCC.NT)(TSX:FCC.NT.A) is pleased to report on recent corporate and operations activity.

On April 19th an inaugural ceremony was held at the Piedras Verdes operation to recognize the completion of construction, commissioning and ramp up toward full production. Distinguished guests representing the Federal and State Governments of Mexico, the Canadian Ambassador to Mexico, other mining companies, contractors and employees of Cobre del Mayo attended the ceremony.

The company is pleased to report that during the week of the inauguration celebration, cathode copper production reached an average daily rate of 87.5 metric tons, or 99.0% of design capacity, including a peak 24 hour plating rate of 91.8 tonnes (104% of total plating capacity). Full production can be expected to be announced once these rates have been sustained over an appropriate period of time.

These performance levels are the result of the success of the adjustments made in the heap leaching process and the regular placement of fresh ore under leach. The average PLS grade for April to date is approximately 1.90 g/l and the average PLS flow to the SX plant over the same period has averaged 1,803 cubic meters per hour. Ore is being placed on the heap leach pad in lifts of five meters (previously 10 meter lifts). To accelerate copper dissolution and improve solution grade, approximately two thirds of the ultimate acid application is being applied by pre-soaking the ore with a strong solution of sulfuric acid prior to rinsing it with normal raffinate solutions.

Phases 2A and 2B of leach pad area are nearly complete and ore placement has begun. Pre-soaking with acid will begin in mid-May, once the construction of the second PLS pond and pumping station has been completed. These construction projects are included in the approximately $30 million 2007 capital estimate.

"I am very pleased with the progress that our operation has made in recent weeks," says Gary Loving, President and CEO Frontera Copper Corporation. "Each mine has its unique challenges, and generating the solution to allow filling of the plant to capacity represents the final step in completing the project. Our focus will now be to continue to improve the efficiencies and costs of the operation while evaluating further opportunities to improve shareholder value."

The company recently completed the limited hedging program, adopted to ensure that sufficient revenues are generated from its copper cathode sales over the next two years to cover certain known financial obligations. For the total program, the Company has placed contracts for 30,575 metric tons of copper at an average price of $2.85 per pound over the 24-month period from March 2007 through February 2009. The average monthly prices received range from a high of $3.11 in May 2007 to a low of $2.58 in February 2009.

The upcoming financial obligations include the repayment of the debt currently issued as free trading notes and planned sustaining capital expenditures. The program provides that the Company may hedge up to 50% of its forecasted production over a two-year period, which would represent about 7% of the recoverable copper contained in the present 13 year mine plan.

The company is also very pleased to announce the appointment of Mr. Tim J. Swendseid as Vice President of Engineering of Frontera Copper Corporation. Mr. Swendseid has over twenty years of underground and open pit experience in various management, supervisory and engineering roles with Phelps Dodge Mining Company (a subsidiary of Freeport-McMoRan Copper & Gold Inc.) and Asarco Inc. Most recently he was the Director of Mining of Phelps Dodge's North American One Mine organization. Previously, he worked at Phelps Dodge operations in Arizona and Chile. Mr. Swendseid holds a Bachelor of Science degree in mining engineering from the Montana College of Mineral Science and Technology and an MBA from the Eller Graduate School of Management, University of Arizona. He is a Licensed Professional Engineer in Arizona and Idaho, a Registered Member of SME and a Member in the Instituto de Ingenieros de Minas de Chile.

Production commenced in October, 2006 and is expected to reach the operations' full annual production capacity of 70 million pounds of copper cathode in 2007. A total of 942 million pounds of copper is projected to be produced during the 18-year life of the operation. Existing resources and prospective exploration targets adjacent to the main open-pit have the potential to extend the life of the project.
