Though diversified mining major BHP Billiton remains confident in the long-term outlook for commodities, it is not waiting for prices to recover. Instead, it is looking to increase value by improving productivity, investing in projects and increasing exploration activity to take advantage of falling costs. “We have everything we need in our portfolio right now to significantly increase the value of the company,” said BHP Billiton chief executive Andrew Mackenzie, who maintained that the company could still value in all market conditions.
