The Superpit
Continuing my “big” theme, here’s a big hole. Those are huge rock-filled dump trucks (with ~8’ wheels) driving up the roads on the far side!
Just outside Kalgoorlie is a gold mining area that was called The Golden Mile - said to be the richest gold deposit in the world. It was mined since the 1890s but as the gold deposits got deeper it became less economic.
Then, in the 80s around a dozen mines were bought up by one company and they started digging the whole thing out! Now there’s a 24/7 operation where they blast a few times a week, and then load all the rock onto dump trucks, and cart it off to the ore crushers. It’s a very impressive operation. Only part of the hole is visible in my picture.
