According to Hilson (2017), Ghana's ASM sector produced 1.2 million ounces of gold in 2016 which represented 31 % of the total gold production. In Ghana, small-scale (gold) mining has two forms: registered (small-scale) mining and informal, illegal or unregistered (small-scale) mining activities, locally called galamsey.
of ASM to total gold production has been rising steadily. In 1989, it accounted for 2.2 percent of total production. By 2014 and 2018, the figure rose to 34.4 and 41.1 percent, respectively, (Ghana Chamber of Mines, 2014 and 2019). Despite the clearly laid out formalization process in the Ghana's Mineral and Mining Act (Act

In recent years, gold production, for instance, has observed to increase substantially from <20,000 ounces in 1990 to 1.6 million ounces in 2016 (Ofosu et al., 2020). The increase in gold mining in Ghana has also seen some significant improvement in the livelihoods of communities where gold mining is in operation (Ofosu et al., 2020).
This unregulated small-scale and artisanal gold mining is known locally as galamsey, a slang word derived from the Ghanaian words "gather" and "sell.". About one million Ghanaians engage in the practice, supporting about 4.5 million people in the country. Many of the galamseyers live in poverty, and their activities often come at a cost ...

5.2. Effect on water. SSM of alluvial gold is believed to be the major cause of river water pollution in Ghana (Al-Hassan and Amoako, 2014, Aryee et al., 2003).Due to the dredging activities and the washing of alluvial gold in the water, siltation is common in major rivers and streams where the miners operate.
The process of alluvial gold mining involves digging and sifting through mud, sand and gravel using shovels, sieves, or even bare hands and this is not the preserve of only galamseyers but all licensed small scale miners. Alluvial mining though regarded the most environmentally friendly method of gold mining as a result of the reduced ...

Artisanal and small-scale mining for example accounted for 43% of Ghana's total gold production in 2018 (Adu-Baffour et al., 2021). Ghana was one of the first African countries to recognize ASM through the promulgation of a landmark Small-scale Gold Mining Law in 1989 (Government of Ghana, 1989) aimed at mainstreaming ASM …
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).
For example, alluvial gold mining operations have been found to pollute over 200 water bodies within mining districts in Ghana. Mining operations damage riverbanks and divert streams from their ...
A total volume of 19328000m3 gold bearing gravels were estimated at average grade of 0.46g/m3 and fine ounces of 261,728 oz based on the gold fines of 920 for the alluvial gold within the area.
