Arch Coal expects earnings to be $900 million to $1.0 billion range and adjusted earnings per diluted share to be in the range of $1.00 per share to $1.40 per share. "The reduction in earnings guidance resulted largely from lost metallurgical coal production at the Mountain Laurel complex," said the company in a statement.

The price of US crude oil crashed through the $80/barrel level on Friday afternoon bringing its losses to more than 10% in September and suffering its worst quarter since the 2008 recession. At the same time the discount on Western Canada Select widened to $10.50/barrel meaning oil sands producers now sell some of the cheapest fuel on the planet. The international benchmark for oil was pegged at over $102 on Friday. Canada exports 2 million barrels of oil per day and a lack of pipelines means all of it goes to the US Midwest, the pricing point for US crude.

A draft law approved by the Indian cabinet today directs miners to share their profits with people displaced by mining. The Wall Street Journal reports that the law, which has been pending for over two years, would have mining companies pay a royalty to create a fund to help for those displaced by mining and related industries. Coal producers would pay a 26% tax on profits. A regulator has also been set up to monitor illegal mining and prosecute violators, in a direct response to recent scandals in the states of Karnataka and Goa respecting the illegal export of iron ore.

Despite a rancourous dispute with local landowners over compensation and infrastructure upgrades and an appeal against a Papua New Guinea High Court ruling approving the dumping, Australia's Highlands Pacific on Friday said it is confident it could power on its already built mine next year after the intervention of a provincial governor. The wrangling over the $1.5 billion Ramu nickel and cobalt mine that over its life will dump 100 million tonnes of waste 400m offshore comes as the new PNG's government moves to quell concerns about proposed changes to mining rights that would potentially force projects worth billions of dollars into renegotiation.
