Since it was friday and most of my friends would be working, I went with the two unattached ladies from the Kruger tour, this was especially convenient since one of them had her company's rental car!
We watched them pour a bar of molten gold, and got to handle a $100,000 bar of gold. There were native dancers giving a variety of performances, including a dance form developed by miners wearing rubber boots.
We put on hard hats, lights and went down to level 5, 226m down, and
went on a tour of the mine shafts.
The winch workings were accessible too, there was a HUGE drum of 2" dia cable for the elevator, only 11 turns were needed for 226m. Apparently the mine has 46 vertical shafts and only 12 go to the surface and everyone has a similar elevator winch. it goes 5000m deep, that's 3 miles!
We walked around the shops, ate lunch, one of the ladies and I went
on a water ride (she panicked and wanted to get off midway!)
