Defensive Mining

We all know about defensive driving. But, there is also defensive mining and I’m not talking about avoiding workplace accidents, environmental damage, public relations problems, etc., although those are all important issues to be defensive about. All over the world, mining is done by a social contract between miners, workers, and communities. But it is also done in the face of an inevitable and reoccurring market cycle that creates risk and a need to mine defensively.

The conventional wisdom holds that mining, and particularly precious metals mining, is an enormously profitable business, and it is true that some mines are profitable and some are even very profitable. However, what about in general and in the long run?

For the most part, mining is a highly competitive and risky industry with market structures characterized by having many sellers of most commodities, many buyers, no significant entry barriers, and miners sell homogenous products. The first two characteristics – many buyers and sellers – imply that buyers and sellers have little pricing power, that is, they are price takers. While entry barriers are greater today than they have been in the past because of regulatory factors like permitting processes, bonding for reclamation, etc., it is still possible to open mines in most political jurisdictions. And finally, product homogeneity means that no copper, gold, silver, iron, etc., miner can claim that their copper, gold, etc. is better than anyone else’s so that they can raise their price.

The implications of this kind of market structure for industry profitability is that in the short run miners can make profits or suffer losses, and in the long run their profits will be approximately zero. To understand, consider the reoccurring market cycle illustrated by the graph below.

The typical pattern is that some outside factor like an increase in demand for some commodity will drive up its price. For example, in the late 1970’s inflation drove up the price of precious metals. This led to an increase in investment in gold mines in the early 1980’s, and then an increase in production in the late 1980’s. This increase in production coupled with European central bank selling in the 1990’s sent prices downward. Mines were closed, merger and acquisition activity in the industry increased and production leveled off and investment declined. Then, in the early 2000’s, with low prices, central banks halted their sales programs reducing supply, and the cycle started again. Since about 2002, gold prices have risen dramatically, investment in exploration and mine development have increased, and prices have started falling.

From 1989 to 2006 the correlation between gold prices and the profitability of major North American gold miners has been 0.05 which means that there is essentially no correlation in the long run. In other words, gold miners at least, have been chasing the cycle like a dog chasing its tail. When prices go up, they invest their increased revenues in expansion and lower their cut – off grades (i.e., process lower grade ores) which raises their costs. When prices fall, they cut back on investment and process higher grade ores to lower their costs. The result is that in the long run the spread between prices and costs stays about the same.

There is a story familiar to most economists (which, sadly, passes for economist humor) that a student once asked Milton Friedman if he would pick up a $20 bill if it were lying on the sidewalk? He is reported to have answered “No, because in long run equilibrium it wouldn’t be there” – just like miners’ long run profits.
