Porcupine Mine

Gold production at the Porcupine mine for the second quarter of 2010 was 14%, or 10,700 ounces, less than in the second quarter of 2009 mainly due to 19% lower grades, offset by 2% higher mill throughput and improved recoveries. The Hoyle Pond underground operation experienced 8% higher grades primarily due to mining in the high grade VAZ and AFO zones and 5% higher tonnage due to equipment availability. The Dome underground operation experienced 53% lower grades, slightly offset by 14% higher tonnage due to mining in the lower grade bulk zones. As anticipated, the material reclaimed from the stockpiles provided 52% lower grades, slightly offset by 1% lower tonnage.

Gold production at the Porcupine mine for the first quarter of 2010 was 21%, or 16,200 ounces, less than in the first quarter of 2009, mainly due to 30% lower grades. The Hoyle Pond underground operation experienced 6% lower tonnage due to equipment availability and 18% lower grades primarily due to timing of development in the high grade VAZ zone. The Dome underground operation experienced 5% higher tonnage and 19% lower grades due to the increased mining dilution resulting from higher development rates. As anticipated, the material reclaimed from the stockpiles provided 2% higher tonnage and 38% lower grades. Cash costs for the first quarter of 2010 were 45%, or $204 per ounce, higher than in the first quarter of 2009 due to lower gold production ($121 per ounce, or 59%) and a stronger Canadian dollar ($107 per ounce, or 53%), offset by lower operating costs ($24 per ounce, or 12%). The decrease in operating costs was attributable to the suspension of the Pamour open pit mining in 2009, explosives ($0.9 million), diesel fuel ($0.9 million) and reagents ($0.5 million).
