This facility was used to crush and process ore worked from the local mines, which you can also visit. The buildings you will see were the offices and houses of the government wokers and the machinery was part of the gold extraction proces.
You will not be disappointed in making the trip out here to see this reserve, close your eyes and imagne what it wuld have been like back in those times. The sun, the heat and those flies.
So glad I was born in the 1970's.
