When the ancient Roman scholar Publilius Syrus said, “No pleasure endures unseasoned by variety,” he could well have been referring to mining companies. One trick ponies, as recent events are sure to prove again, live and die the by price of a single commodity, and as such, are more vulnerable to sudden or unexpected market movements than are polymetallic companies.
