Costs going down

Looking at the notes on the 2014 financials NCM entered into short term hedges on its diesel fuel of 471,000 contracts at an avg price of US $118/barrel. With oil taking a 40% haircut this is a nice add to bottom line when these contracts expire and are rewritten at the lower price. I would assume in this period of deflation in the mining sector with job losses in other sectors like iron ore that Newcrest will also be able to hold labour costs down as well.
