UTAH – The Lisbon Valley copper mine 72 km southeast of Moab has produced its first copper cathodes, says owner CONSTELLATION COPPER of Denver. The first 2,400 sheets were harvested on April 14, 2006. Another 5,280 sheets were harvested last week.
Constellation says most mining and processing circuits are performing near or above 90% of design capacity. The exception was the solution flow volumes, which will increase as the plant ramps up to full capacity. The start-up of the electrowinning facility went smoothly with little iron in solution. A description of the project is posted at www.ConstellationCopper.com.
The Lisbon Valley cathodes are sold to Sempra Metals and Concentrate under an off-take agreement. Constellation receives the prevailing COMEX price plus a premium of US$0.07-$0.08/lb. Designed capacity of the project is 54.0 million lb of cathode copper per year.
