Impact of Illegal Gold Mining / Panning on Farming

2020-4-26  Gold mining in Zimbabwe‟s farming communities represents all methods of gold extraction from deep underground mining, to small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning along major rivers. Artisanal mining and processing methods are employed to work both hard rock and alluvial gold deposits. Seam gold is mined by excavating pits to levels where “a dark coloured stone which is interspersed with gold” is reached. The gold is then recovered “by grinding the stone to powder”, and then “washing it”. In Zimbabwe alluvial gold is mined by collecting gravel from the beds of streams/rivers and washing sediments clean of sand and earth. The practice which is popularly known as „chikorokoza‟ is flourishing along major rivers and the recovered gold is mainly smuggled to neighboring South Africa and Botswana for trade through black market channels. Despite contributing nothing economically, panning

2021-6-28  ASM activities are usually either carried out in alluvial or hard rock deposits (Jonsson and Bryceson, 2009). Alluvial mining consists of extracting material from sand and gravel in riverbeds, while hard rock deposits are drilled or blasted so as to loosen the mineral ore (Jonsson and Bryceson, 2009).

Indigenous Gold Mining in Southern Africa: A Review

These 'gold belts' in Zimbabwe were the source of most gold that was mined in southern Africa during the Late Iron Age (Fig. 2).

Together, the quartz veins exposed in gold bearing reefs, and the
