To be sure Goldcorp was really just pitching its own balance sheet, and was more focused on its far more levered gold-mining competitors going out of business...
... and hence facilitating "peak production" this year as one after another producer is forced to file for bankruptcy, than actually making a statement on how much gold remains to be mined in the ground. Because the last thing even the most healthy gold miner, with the lowest production cost wants, is to face a world in which their primary commodity is running out.
Which may just be this world.
According to a report issued by Goldman's Eugene King looking at commodity scarcity, the chart below "shows that there are only 20 years of known mineable reserves of gold and diamonds."
Some futher observations on gold and scarcity in general from Goldman:
The combination of very low concentrations of metals in the Earth’s curst, and very few high-quality deposits, means some things are truly scarce. Perhaps unsurprisingly, these are the so-called precious metals (and diamonds), and that their value is derived from the fact they are rare.Their relatively scarcity, and the market’s belief that new discoveries will be limited, is what drives the price of these super rare commodities. Take diamonds as perhaps the most extreme example. A diamond has very little intrinsic value. Its value is determined by a belief that it is rare and, for a natural diamond, unique.Gold has been used as a measure of wealth for more than 4,000 years, as the ancient Egyptians soon worked out that gold was not only shiny and heavy, but rare.
Of course, this analysis is meaningless in a vacuum: if the "known reserves" of gold plunge in the coming decade, no matter how many gold futures and GLD short sales are conducted by the BIS, the price will have to go up, and it will go up high enough to where a new surge of gold miners will come online and find thousands of new tons of gold reserves around the globe.
Unless they don't, and Goldman is correct that "peak gold" may have arrived. This will be even more true if over the coming years the long overdue fiat economic panic finally washes over the globe, and a revulsion toward central bank policies forces a scramble into gold whose value (if not price since fiat currencies will be redundant) soars.
The answer is unclear, but what is certain is that like the price of oil over the past decade and until last fall when price discovery finally became somwhat credible, what happens in the physical realm has absolutely zero marginal impact on the price of commodity which has about 100 ounces in deliverable paper contracts for every ounce in underlying. It will be only after the gold price distortions via the derivative market are eliminated that such trivial price-formation forces as supply and demand are once again relevant."
