FORZA ITALIA'S Travelblog: Underground Gold Mines

so when gold was discovered in south africa late in the 19th century, there was a huge influx of ppl to try and reap all that...many miners were obviously abused and all that good stuff...at its height, early in the 20th century, 27% of worldwide gold was coming from south africa...there were tons of mines like this....this one, went down 3 km...naturally we were only at like 100m-250m below the ground...i can't even imagine going down that deep....way too hot.
