Artisanal and small scale gold mining (ASGM) is an informal economic activity. ASGM is the process of extracting gold ore from the ground in the absence of land rights, mining license, exploration or mining mineral exploration permit or any legitimate document that allows the operation. Its haphazard nature, location close to and dependence on water …
Ghana retained its spot as Africa's biggest gold producer last year, as increased production from small-scale and artisanal miners pushed output to 4.03 million ounces.

Often when artisanal & small-scale miners produce gold observing relevant environmental, social and governance standards, practical barriers to accessing international markets still remain. This report offers insights for securing a brighter future for the legitimate, safe and clean flow of artisanal and small-scale gold to market.
Mercury releases to air, water and land from artisanal and small-scale gold mining (ASGM) are estimated to be over 2000 tonnes each year (UNEP Global Mercury Assessment 2018). It is the sector demanding the largest quantity of mercury, with virtually all of the mercury used released to the environment. The sector produces about 12 to …
The 2019 State of the Artisanal and Small-Scale Mining Sector report showcases data contributions made to Delve and demonstrates the potential for a deeper sector …
Artisanal and small-scale gold mining (ASGM) sites are spread out across thirty provinces in Indonesia, and have provided work opportunities and income for more than two million people. However, the majority of ASGM activities use rudimentary technologies that have serious impacts upon the environment, public health, and miners' …

Implementing retorts in artisanal and small-scale gold mining (ASGM) to mitigate mercury emissions is a positive development. However, it creates a new challenge: the need for proper management of retorted mercury waste. This study aimed to estimate the global waste management cost for retorted mercury using stringent guidelines for …

Rapid Assessment of the Impact of COVID-19 on the Artisanal and Small-Scale Gold Mining Sector in Sierra Leone. In 2021, the AGC undertook a study on the impacts of COVID-19 on the ASGM sector in Sierra Leone. This report highlights the results, focusing on impacts to miners' livelihoods, gender impacts, and disruptions to the informal gold ...
The past decade witnessed the initiation and boom of the Artisanal and Small-scale Gold Mining (ASGM) activities in the hyper-arid southern Egypt. The ores are mined in the Eastern Desert and then transported to the densely populated farming communities in the Nile Valley, where the river provides the water resources needed for …
Bone River, which is located in the eastern part of Gorontalo, Indonesia, has an issue of contamination by heavy metals due to artisanal small-scale gold mine (ASGM) activities. This river is used as a source of water by inhabitants living along the river, due to the lack of another clean water supply. The purpose of this study is to …
Artisanal small-scale gold mining (ASGM) is one of the major sources of mercury pollution in Indonesia.

Abstract Artisanal and small-scale gold mining (ASGM) utilizes mercury (Hg) for the extraction of gold (Au) and is responsible for the largest anthropogenic source of emissions and releases of Hg to the environment. Previous estimates of Hg use in ASGM have varied widely. In this effort, Hg losses in ASGM were derived from the difference …
The World Gold Council and its member companies support the responsible mining and trading of gold from all legitimate sources, including artisanal and small-scale gold mining (ASGM).
1. Introduction. Disparate and incomplete data makes it challenging to address the complex and multifaceted issues involved in mining (Lèbre et al., 2019, 2022).A prominent example is artisanal and small-scale mining (ASM), which is conducted by individuals, groups, families, or cooperatives, typically with minimal or no mechanization, …

Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
