Mining's biggest loser Lonmin is burning cash to stay alive

For most of the mining industry, 2017 is turning out to be another good year. The big exception is Lonmin Plc. Investors are losing confidence in the world’s third-largest platinum producer as it burns through cash to stay afloat, just 15 months after raising about $400 million from shareholders. Platinum prices aren’t far from a seven-year low and Lonmin has its own set of operational problems, including higher costs and lower output at its biggest mining shaft.
