Robinson Mine Expected To Produce 125 Million Pounds Of Copper For The Year
VANCOUVER, BC - Paul Blythe, President and CEO of Quadra said that,The Robinson Mine, in Nevada, continued to generate the majority of our overall revenues and operating income during the quarter, however, as we have mined further into the Ruth pit, which will be the only production pit by the fourth quarter, an area of underground workings from the 1950's has proven to be larger than expected. These workings were block caves where higher grade ore was extracted, with lower grade material then caving in to fill the voids. While we continue to understand and evaluate the impact of this block caving, we feel it prudent to lower Robinson's copper production expectation to 115 -- 125 million pounds of copper and 75,000 ounces of gold for the year (previously 135 million pounds of copper and 80,000 ounces of gold). We were aware of the underground workings at Ruth and have relied on historical records to understand these. Now that we are well along with dewatering the pit, we have the drill access required to drill from the bottom of the pit to confirm the full extent of these workings, and this work is in progress."
The Robinson Mine as it exists today was built in 1994 through 1996 for approximately $480 million and ran until operations were suspended by BHP Copper in 1999 due to low commodity prices (60ó per pound copper and $260 per ounce gold). The Company purchased the mine from BHP Billiton in April 2004, and immediately recommenced operations, reaching full production in October 2004 more than two months ahead of schedule and following capital upgrades to the process plant facility. The mine mobile equipment had been reassigned to another BHP Billiton project and was replaced with new equipment. The current mine infrastructure consists three large open pits; Liberty (previously mined out by BHP Copper), Tripp-Veteran, and Ruth, a conventional process plant with SAG and ball mill grinding followed by floatation. A molybdenum recovery circuit was constructed by the Company and entered operations in December 2005. Robinson has operated continuously since 2005 producing on average, 121 to 126 million pounds per year of copper. In 2006, mining transitioned from the Tripp to the Veteran pit and the mine produced 121.4 million pounds of copper, 75,074 ounces of gold and 260,000 pounds of molybdenum. In 2007, the mine produced 131.9 million pounds of copper and approximately 108,000 ounces of gold and production for 2008 was a historical record for the mine for both copper and gold. Robinson produced 159.7 million pounds of copper in 2008 and 137,628 ounces of gold. The reserves at Robinson as of January 1st 2009 were 121 Mt containing 0.54% copper and 0.23 g/t gold.
