Hydro-metallurgical extraction processes have also improved over the last 100 years so the amount of metal recovered from their concentrates could increase dramatically.

Important to note that all original mine discoveries were made due to outcropping at surface. The old miners would never have found it if wasn’t sticking out of ground.

With modern geophysical exploration methods there is a massive chance they could find more high grade deposits scattered throughout their tenement.
