In its Third Quarter 2011 Results released today, the Company reported revenue for the quarter of $103.5 million from a record average gold price received of $1,706 per ounce. This represents a 9% increase on the previous quarter and a 24% improvement on the same period last year. Revenue for Year-to-date (YTD) 2011 reached $289.0 million and was another notable gain, exceeding the 2010 result of $211.8 million by 36% and again driven by higher gold prices.

Gold sales for the quarter were 60,646 ounces with cash costs of $956 per ounce, slightly higher than the previous quarter at $921 per ounce. The Company’s Didipio Project in the Philippines also made solid progress throughout the quarter with construction activities progressing to plan.

OceanaGold CEO, Mick Wilkes, said the Company’s third quarter results were buoyed by the strong leverage to a rising gold price. “We are pleased with the operational improvements we have achieved at Macraes and Frasers over the past quarter and continue to work on getting the Reefton operations back in line with expectations. Despite some weather related events at Didipio, progress there is tracking well and we are looking forward to achieving some key benchmarks such as pouring concrete at the project before the end of 2011,” he said.
