Gold production in Nigeria is believed to have started in 1913 and got to its peak from 1933-1943 (MMSD, 2010). Gold in the schist belt of Nigeria occur as alluvial and elluvial deposits. Only 5 …
The results indicate that structures are more important in the control for the occurrence of gold in Wonaka schist belt than lithology. View full-text. Article. Full-text available.
Such gold mineralized fluids were produced through a large-scale metamorphic process along faults and shear zones of the Zuru Schist Belt, which enabled migration of the gold-bearing fluids from their source areas to the accumulation locations during the waning stages of the Pan-African event (Garba, 2000).

The Kushaka schist belt exhibits gold mineralization mainly in veins and stockworks and in placer deposits found in eluvial and alluvial sediments [1][2][3][4][5][6][7].
The Proterozoic Kushaka schist belt of northwestern Nigeria is well known for its alluvial gold occurrence, although the primary source of gold is unknown due to the extensive thick weathering ...
Abstract-Occurrence of gold in placers and primary veins is know in several areas of the western half of Nigeria from Anka and Maru in the northwest in primarily super crustal (schist's) belts.

1. Introduction. The Ibala gold field is a group of alluvial mines discovered by artisanal miners in 2018. These mines are situated to the east of Ibala town in Osun State, southwest Nigeria (Figure 1).Gold extraction involves hand-dug trenches that extend to depths over 5 metres, and in certain locations, pits are dug vertically to about 12 metres (Figure 2).
gold assay hotspots, indicating that orogenic gold mineralization in this belt is connected to Pan-African orogenic events. Fractured zones with disseminated gold-sulde deposits and hydrothermal alteration halos exhibit low resistivity and high chargeability signatures. However, the occurrence of disseminated gold-sulde deposits that inlled ...
A significant number of gold occurrences are hosted by hydrothermal alteration zones in the Zuru Schist Belt, Northwestern Nigeria. The aim of this study is to identify the spatial correlation between faults, sheared, hydrothermally altered zones, and gold mineralized areas using geophysical and remote sensing data. The main structural trends of the schist belt as …

Nigerian gold mineralization has been identified to occur in primary, eluvial and alluvial forms, with around 90% of production coming from the alluvial sources. The Wonaka Schist belt has been recognised to consist of placer gold with mostly erratic and irregular distributions within the river systems. Despites such occurrences, the distribution,
