Mining in Malolotja
(Updated by Bob Forrester, December 2005)
Malolotja Nature Reserve, with its fascinating geology, is home to a number of old mines. Anyone interested in the history of Swaziland should visit them. Gold is concentrated in the rocks of the Swaziland Supergroup in a belt extending along the north western border of Swaziland from Ngwenya to Horo. It is an area of complex geology with extensive folding, overfolding and shearing. Within the reserve the gold mines are found on the south eastern border, at Forbes Reef and at the top of the Malolotja valley.
There is slight evidence that some tin mining has taken place in the reserve. Two miles west the Forbes Main reef and one mile west of the gold deposits, two areas of casserite have been found. A small amount of trenching and investigation has been carried out although no records of them can be found. Local people living in the area also speak of the old tin mines.
