After a tailings dam burst at Imperial Metals’ Mount Polley mine in B.C. in August, Edwards pumped $40 million into the company as part of a $100-million emergency bond issue. The personal commitment from Imperial’s controlling shareholder helped halt the stock’s free fall. It’s been a lousy year for the resource tycoon, with key assets caught up in the crude oil price swoon. But there are benefits to diversification: Edwards’ Magellan Aerospace is up 50% year-to-date.
