Evaluation of Placer Deposits in Ghana: a Case Study of
Nov 30, 2019 Alluvial gold deposits occurred throughout the country in favorable areas overlying Birimian metavolcanics and metasediments rocks. The vast majority of historical gold production from Ghana prior to the 20th century came from a myriad of small streams and rivers draining areas with underlying oxide and primary gold deposits (Hilson, 2002).
A Contextual Review of the Ghanaian Small-Scale Mining
Tarkwaian gold deposits have experienced several episodes of erosion and subsequent deposition. Small-scale gold mining is, for the most part, confined to these areas, since most operators lack the requisite mechanized equipment to mine hardrock deposits of the Birimian and Tarkwian Belts. The rivers and waterways highlighted on the map contain the

iii) Recent placer gold deposits. Both alluvial and eluvial gold deposits occur in Ghana. The alluvial deposits however are the most common and occur in gravels of streams, river flats, old valleys and on terraces and in beach sands and gravels. They are derived mainly from the primary vein and lode-type deposits associated with the Birimian.
