Inside Australia's deepest gold mine — how deep can history go at Gwalia? - ABC News (Australian Broadcasting Corporation)
A truck driver working at the bottom of Australia's deepest gold mine gets loaded up with about 55 tonnes of precious cargo — hard rock blasted from the Earth and containing small specks of the yellow metal.
For every tonne trucks cart to the surface there might be only seven grams of gold, the equivalent of about one teaspoon.
===========================================
'This is Gwalia in Western Australia's remote northern Goldfields.'
Interestingly, Herbert Hoover, the Republican President who brought the world the Great Depression, was once manager of this deep mine after graduating for Stanford U. in the 1890s. And they are still digging deeper to get the gold. At something around $1,200/ounce, this deep truck mining is still profitable.
To date this mine has yielded $10BN at today's gold prices. Eighty-three miners have died in the process.
