Here is one interpretation of when we’ll run out of each metal or energy source. While the technicalities of some of this information can be debated, I think the general theme runs the same. There is a limited supply of these commodities – and if there are no discoveries, no price changes, and no changes in consumption, we are running out relatively soon. In my opinion, there are two caveats that are always worth considering when looking at something like this.
1. “Reserves” are an engineering number that are based on economic viability. Technically speaking, there are small concentrations of gold everywhere. It is just not usually viable to mine 0.1 g/t gold. When we will “run out” of each mineral in this chart is based on current reserves and prices. If the gold price doubles, then suddenly it is economic to mine more.
2. This chart is a reminder that something has to give. Either prices are going to have to go up, or new amazing discoveries have to be made to keep prices down. It’s basic economics, and either way it seems that there are many opportunities in the mining industry for investors and speculators on both fronts.
