As noted above, production improvements achieved during the second quarter of 2010 were improved in July and then again in August. Mercator expects to continue at these performance levels until the additional flotation tanks are brought on line the first of October and then, subsequently, when the Phase 2 expansion is completed.

Mercator reports that construction of the rougher flotation expansion continued on schedule with the completion of concrete and support steel, and mechanical and electrical on schedule. The tanks are scheduled for start-up the first of October and will provide additional retention time, which is expected to further improve copper and molybdenum recoveries. All four Phase 2 ball mill shells are on site and installation is in progress. All the concrete for the Phase 2 ball mills is complete. During the month financing was arranged and an order was placed for a 35 megawatt GE LM 6000 gas turbine which when installed will supply all the power for Phase 2 production of 50,000 tons per day of mill through put. The turbine is scheduled for delivery the first of December 2010 and scheduled to be fully operational in April of 2011.
