In the first quarter 2008, the mine produced 42.0 million pounds of copper and 37,738 ounces of gold. Both copper and gold production were quarterly records for Robinson, exceeding any previous quarterly production as operated by Quadra or any prior owner of the mine.

Several favourable factors and developments combined during the quarter to produce these results. The mine is currently producing exclusively from hypogene ore and the hypogene encountered in the first quarter had higher than average grades. In addition, blending and reagent strategies developed in 2007 resulted in some of the highest recoveries so far to be achieved from the Veteran pit. The gold grade and recovery were also higher than expected, notwithstanding adjustments made based on the results from 2007.

Paul Blythe, President & CEO of Quadra said, “This was obviously a very good quarter for Robinson and for Quadra. Congratulations are due to the Robinson team on all the work and innovation that has led to this outcome. As well as the record production volumes, the substantial sales volumes achieved are important to us during this period of high copper and gold prices. Of course, it would be remiss not to re-iterate that Robinson is a skarn deposit with inherent variable mineralogy and that will continue to result in uneven production quarter over quarter. As such, we are currently not in a position to revise guidance but management will continue to assess the impact of new strategic initiatives on production going forward.”

The first quarter financial results will be announced on May 13th, 2008.
