I was just reading about the pyramid and what the scans show (another possible tomb) and wonder what that means for the precious metals market. If ground scan sonar becomes capable enough the mining of everything will be more profitable because they will know exactly where the seams are so you would have a far higher percentage of recovery per investment.
People like to say there is a finite amount of precious metals and they are right. What they don’t say is we have likely recovered single percentage points of the materials because technology has never allowed us to pinpoint where it is under the ground (only where it should be for gold).
That might do even more to the gem markets. Most gems form in cavities. (Diamonds are the common exception).
