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.
