2021-2-21 WOMEN AND ARTISANAL SMALL- SCALE GOLD MINING: KENYA. Economic Activities in Artisanal and Small-Scale Gold Mining The Matanda mine is on trust land in an area where colonial-era hard rock mines date to the 1930s. Mining shafts are deep, requiring machinery, blasting and/or water removal to excavate the mineral-bearing ore.
MoreSignificant amounts of gold have been identified both within the alluvial and colluvial deposits located on the license. Current hard rock artisanal mining activities within the area are focussed on large quartz veins, producing exciting quantities of gold every month. Heavy Mineral Sands – A Significant Find

MoreArtisanal mining in Uganda started with the discovery and establishment of a number of colonial gold and tin mines across South Western Uganda between the 1920s and 1950s when small‐scale mining was introduced to the indigenous Banyankole, Batoro, Bakiga, and other Bantu‐speaking tribes of that region. In 1929, colonialists settled in Busia ...
