Boart Longyear has posted a steep loss and says it will review its operations after having slashed almost 3500 jobs in the past year.
The world's largest drilling company predicts key commodity prices will remain weak this year.
Yesterday, it posted a full year net loss of US$620 million in 2013, down from a US$68 million profit in 2012, hit by US$461 million of restructuring costs and impairments after cutting 3481 jobs during the year.
Chief executive Richard O'Brien has left the door open for more job losses and says the US-based company will leave all options on the table as it focuses on debt reduction and improving its capital structure.
"To that end, we have initiated a strategic review to ensure all options are considered carefully and completely, not only to meet today's needs but to position the business to capitalise on future opportunities," O'Brien said.
