Ethiopia EITI
Ethiopia is a significant producer of gold and limestone, and also produces smaller quantities of tantalum, salt and pumice. The latest EITI reporting shows that the mining sector accounted for 1% of total exports and 14% of total employment in 2019. Oil and gas exploration activities are ongoing, although no commercially viable discoveriesIn 2020, production from artisanal and small-scale mining accounted for nearly 70% of total primary tantalum supply (Friedline, 2022; Roskill Information Services Ltd., 2020; Tantalum-Niobium International Study Center, 2021c).Dynamic material flow analysis of tantalum in the United States

Tantalum supply from artisanal and small-scale mining: A mineral
The growing livelihood significance of ASM activities at a global scale necessitates formalization efforts that include, among others, increasing non-discriminatory market access for artisanal mineral products (Sovacool et al., 2020).This implies the need for evaluating ASM production as a potential long-term source of mineral supply, in This article examines the impact of artisanal and small-scale mining (ASM) on livelihood in mining communities in Rwanda (Rutsiro) where wolframite and coltan are mined. The paper discusses the development of ASM and other entrepreneur activities, in particular agriculture. With ASM activities, there is environmental degradation on the IJERPH Free Full-Text The Livelihood of Artisanal and Small-Scale

Coverage of artisanal and small-scale mining (ASM) in EITI reporting
In many resource-rich developing countries, the extraction of minerals by artisanal and small-scale miners plays a significant role in national mineral production and economic activity. According to the global data platform on artisanal and small-scale mining (ASM), Delve,the ASM sector is estimated to comprise nearly 45 million people worldwide and The use of tantalum is problematic due to its primary production, which mainly takes place in the Great Lakes region in Africa through artisanal and small-scale mining (ASM) under questionableGrade-tonnage diagram for tantalum mining and exploration

Child labour in mining and global supply chains
Child labour in mining is most commonly found in artisanal and small-scale mines (ASM). Even if produced in small quantities at a mine site, cumulatively, the quantity of minerals coming from ASM is significant: ASM accounts for about 20 per cent of global gold supply, 80 per cent of global sapphire supply and 20 per cent of global Global tantalum production volume 2022, by country.

Tantalum: 101 Mining & Investment Resource Capital Funds
Australia’s historical tantalum production has come from just two mines, Wodgina and Greenbushes. Both mines ceased tantalum production in the late 2000’s, which provided an opportunity for small scale artisanal production from Rwanda, and the Democratic Republic of Congo to fill the supply gap.80% share in the large-scale diamond producer Société Minière de Bakwanga (MIBA).
