Canada’s Mandalay Resources (TSX:MND) has put its Cerro Bayo underground silver-gold complex in Chile on care and maintenance as a result of a June incident that caused one of the three mines to flood, killing two workers.

Shares of small producers, mainly focused on mines in southern Africa and Canada, have tumbled more than 30 percent during the past year and each company seems to be embroiled in its own mess.

The issues range from mine setbacks, political fights and low prices for certain types of stones. The volatility is normal for such a speculative corner of the industry, but the losses are surprising since rough-diamond prices have held up relatively well. (See full article here)
