In the third quarter of 2007, copper production of 30.7 million pounds was in line with block model estimates that provided the basis for Quadra's 2007 production guidance of 125 million pounds of copper. Ore was largely mined from the supergene zone. As anticipated, copper recoveries were impacted by the presence of copper oxides, both acid soluble and non acid soluble ("NASOX"), that are associated with this zone and which are not amenable to flotation and therefore not recoverable. Gold production continued to exceed expectations and remained at levels higher than predicted by the block model.

Paul Blythe, President & CEO of Quadra, said, "We have maintained our production momentum at Robinson throughout the third quarter. As we mined through the ore that has given us recovery issues in the past, including the copper coated pyrite and the NASOX material, we again experienced lower recoveries during the quarter. This supergene zone will continue to provide the ore feed well into the next quarter but as noted, the impact of this material is built into our annual copper production estimates for the year and we are expecting to meet or exceed our copper guidance."

"The work we are doing to improve our gold production estimates are well in hand. Based on our gold production trend and year to date results we are expecting to exceed our current gold guidance of 90,000 ounces for the year."

The financial details from this quarter are due to be released on Monday, November 5th, 2007.
