Miners struggle with debt refinancing after prices slump
Competition from Australia and dwindling demand add to woes for Chinese and Mongolian producers

The coal sector is taking a beating, with prices down 35 per cent from their November 2011 peak.
Cheap Australian coal is undercutting prices to the point where mining is unprofitable for regional producers, particularly Mongolian mines. Firms that borrowed to fund expansion during coal's boom year of 2011 are now on the hook to refinance debt, and banks and bond markets are baulking.
Winsway Coking Coal, which transports Mongolian coal to the mainland, asked investors last month to exchange an outstanding US$460.5 million bond for a new one and lose more than half their capital in the process. Investors who accepted the deal did so in the knowledge that rejecting it would likely send the firm into default.
As it was, Moody's Investors Service described the offer as a technical default in itself. "The [Winsway] transaction will constitute a distressed debt exchange, which is a default event under Moody's definition," it said.
Elsewhere, Mongolian Mining has asked banks and investors to extend repayment of various debts.
