Altura Mining Limited provided earnings guidance for the six months ended December 31, 2011. For the period, the company announced that net loss was likely to be in the range of $0.4 million to $0.6 million. This compares with the company's result for the six months ended 31 December 2010 of a loss of $0.9 million. The reduced loss in the current half year is mainly due to a favorable foreign exchange movement, an improved operating performance in the drilling business and higher interest income partially offset by higher administration and employee benefits costs during the six months.
