Phase II start-up

The construction of Phase II expansion was completed during the third quarter 2011. The natural gas turbine generator went into service on August 15th. The Phase II ball mills and rougher flotation circuit went into service on August 18th. The Phase II crusher went into service September 30th. The plant has operated individual days in excess of 60,000 tons per day and has averaged over 45,000 tons per day in the first 45 days of commissioning.

Previous guidance for the third quarter 2011 was 12 million pounds of copper and 1.7 million pounds of molybdenum, or 22 million pounds on a copper equivalent basis. Third quarter 2011 production of 10.5 million pounds of copper and 2.0 million pounds of molybdenum is approximately 22.3 million pounds on a copper equivalent basis.

"Phase II start-up is going extremely well with recoveries and mill throughput holding very close to design for both copper and molybdenum. On a copper equivalent basis, we achieved our production targets for the quarter," says Bruce McLeod, President and CEO of Mercator. "Our focus in the upcoming quarter is to sustain Phase II targeted production levels of at least 50,000 tons per day, while maintaining recovery levels and lowering production costs. With construction of Phase II behind us, we will be providing 5-year production guidance in the coming weeks."

Copper Forward Sales

After taking into account copper delivered against hedges for the first three quarters of 2011, there are 8.5 million pounds of copper remaining to be delivered in the fourth quarter 2011 at an average price of $3.12 per pound. Further information on the forward sale positions can be found in the Company's second quarter 2011 financial statements, which can be found on SEDAR ( and on the Company's website (
