HudBay Minerals Inc. has released its first quarter 2011 financial results. Net profit attributable to shareholders increased to $16.8 million or $0.11 per share in the first quarter of 2011, compared to $10.6 million, or $0.07 per share, during the first quarter of 2010. Earnings in the first quarter of 2011 included a charge of $5.8 million, or $0.04 per share, for transaction costs associated with the successful acquisition of Norsemont Mining Inc. in March 2011. Earnings grew during the quarter mainly due to higher metal prices and reduced exploration expense, partly offset by lower sales volumes, a stronger Canadian dollar and Norsemont transaction costs.

The Oyu Tolgoi Project initially is being developed as an open-pit operation, with the first phase of mining planned to start at the near-surface Southern Oyu deposits, which include Southwest Oyu and Central Oyu. A copper concentrator plant, related facilities and necessary infrastructure that will support an initial throughput of 100,000 tonnes of ore per day are being constructed to process ore scheduled to be mined from the Southern Oyu open pit. Commercial production of copper-gold-silver concentrate is projected to begin in the first half of 2013.
