The absence of these elements in some of the gold suggests that alluvial gold would have been exploited, although we cannot rule out the exploitation of primary deposits. While detailed provenance studies are required, existing compositional studies revealed that Great Zimbabwe's gold is argentiferous (Grigorova et al. 1998; Bandama …
Y-t-d mine production of 2,744t is also a record: up 1% over the previous Q1-Q3 record of 2,706t achieved in 2018. On a q/q basis, production increased by 6%, due primarily to normal seasonal fluctuations. Global gold production shows modest seasonality: in the ten years to 2022 first-half mine production averaged 48% of the …

Current (official) gold production in Zimbabwe is 33.2 metric tonnes (2018) to 27.5 metric tonnes in 2019 – the approximate equivalent of what was produced in each of the fifteenth and ...
Twenty per cent of the country's gold mines and 75% of chromite mines were classified as small, based on tonnage of ore. These categories of mines produced between 0 and 50 thousand tonnes of ore per year. Other commentators have estimated the small-scale gold sector to account for 20% of gold production in Zimbabwe [1].
With Government relying heavily on gold production to increase revenue, it is important to scrutinise the ban and question whether it serves the country's best interests. ...

6 In some areas, alluvial gold was worked by shafts sunk into river banks and reef mining may have developed from this technique; see, for example, The Rhodesian Mining Review, 19 02 1913, 185. For further details of alluvial mining methods, see I. R. Phimister, 'Placer mining in South Central Africa', unpub. research paper.Google Scholar
Introduction. This presentation highlights environments in which alluvial gold may be concentrated. The aim is to show the wide diversity of the alluvial depost-types so that appropriate titles and tenure for their exploraton are discussed.
