The site was first discovered in 1905. The Rooiberg Tin Mine is a underground mining operation. Initial production took place in 1908 and overall output was considered to be medium size. Mine operations consist of 2 distinct underground workings. There are a total of 2 shafts. Subsurface depth reaches a maximum of 150 meters (492 feet).

The treatment principle of gold-pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation. There're 4 extraction processes. #1 Roasting-Cyanidation Treatment

Terrace mining is similar to open-pit mining as a large hole of about 12 meters is dug here too. In the terrace-mining method, steps or "benches" are created parallel to the pit on the way to the bottom. These benches can be used as exploration spots, where miners search for emerald-rich rock, or they can be used to move away waste rock.

Cassiterite is a tin oxide mineral (SnO2) and the principal source for tin metal (79.6% Sn). The color is shining black, brownish-black ( Fig. 1.34 ), reddish brown, gray, red, white, and rarely colorless. The crystal system is tetragonal with very common twinning. The fractures are subconchoidal to uneven and brittle.

This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz - gold bearing veins can consist of calcite or mostly sulfides - which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.
