VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 25, 2011) - Quadra FNX Mining Ltd. ("Quadra FNX" or the "Company") (News - Market indicators) announces its second quarter 2011 production and sales results. Combined payable production for the three months ended June 30 totaled 55 million pounds of copper, 27 thousand ounces of total precious metals ("TPMs") and two million pounds of nickel.

1. Payable Cu and Au produced in concentrate
2. Payable Cu produced in cathode
3. Shipped payable metal
4. The average price used to value provisionally priced copper

Paul Blythe, President & CEO comments; "Our production profile improved through the second quarter as optimization initiatives at our operations began to deliver positive results and we expect this trend to continue in the second half of the year. The ongoing measures to improve flexibility at Robinson are on track, and Franke is now back at full mining capacity. Overall, our consolidated copper production is expected to be within the previously stated guidance of 240 million pounds +/-10%. We have also made progress on a potential re-start of our primary nickel capacity at our Sudbury operations with a waiver obtained from Vale. Our team remains focused on our existing operations and advancing our significant growth profile."

SECOND QUARTER OVERVIEW:

At Robinson, the removal of mud from the bottom of the Ruth Pit was completed approximately four weeks ahead of schedule and the secondary access ramp remains on track for completion in August. As previously indicated, the production profile at Robinson is back-end weighted, benefiting from access to higher grade material at the bottom of the pit and the removal of the existing north ramp, as well as additional haulage capacity. As the third quarter started, the grade profile at Robinson increased significantly versus the second quarter, and ore grades are expected to further improve in the fourth quarter.

In Sudbury, copper production at all three operations was above plan. During the quarter the Company reached an agreement with Vale, whereby Vale waived its right to the high-magnesium oxide (MgO) nickel ores from McCreedy West for a period of three years. The Company has subsequently entered into negotiations for the sale of this ore to another party and nickel ore mining has recommenced at McCreedy West to provide a bulk test sample.

At Franke, the transition to owner mining and plant maintenance, as well as the purchase of all additional mining equipment, was completed during the quarter, so that mining volumes at Franke continued to increase as planned. Following the completion of the transition from truck dumping to conveyor stacking at Carlota, the Company is evaluating options going forward.

Q2 FINANCIAL RESULTS AND CONFERENCE CALL DETAILS: The second quarter financials will be issued on August 10, 2011 prior to market open. A conference call to discuss the second financial results has been scheduled for August 10, 2011, at 10am ET (7am PDT). Dial in details of the accompanying conference call will be issued under separate press release.
