Tony Makuch, President and CEO of Lake Shore Gold, commented: 'A significant highlight of the first quarter 2011 was our cost performance, with average cash costs at Timmins Mine during the first quarter of commercial operation being $92 per tonne and very close to our full year target average for the Mine of US$575 per ounce despite the anticipated lower grades due to mine sequencing. Output from Timmins Mine is expected to be weighted to the second half of the year once mining resumes in the Timmins Mine Ultramafic Zone near the end of the second quarter. At the Mill, recoveries continue to be excellent. In terms of throughput, we have addressed some issues to more effectively manage the flow of material through the circuit. We are already seeing improvement and expect to achieve average throughput of 2,000 to 2,100 tonnes per day on a sustained basis by the end of the second quarter, with higher rates targeted for later in the year.'
