The repeatedly deformed and metamorphosed Adola Precambrian Greenstone Belt of Southern Ethiopia which is well known for its gold potential has been Placer gold in the Megado belt was first discovered in 1936 and, since then, more than 55 tons of placer gold has been produced.

Abstract Economic analysis for multiple hypothetical placer gold mine models was conducted and its result is plotted on four graphs, each represents deposits Primary and placer gold mining sites in southern Ethiopia were studied to see the contribution of mining to the accumulation of metals in different environmental Metal contamination of the environment by placer and primary gold
The paper reported the information on geology, alteration pattern, ore minerals and geochemical investigation for gold and base metals and to delineate potential area of gold and base metalsIt is proposed that the Adola placer gold was derived, ultimately, from the ultrabasic rocks which are now represented by serpentinites and talc-schists. During the process of Serpentinites as a possible source of the Adola placer gold,

reported to contain 20-30% of the whole estimated gold reserve of the Adola region. Tsegaye Desalegn and Holloway (1955) are also credited for the placer exploration of the area. In the period 1956 to 1965 the prospecting and exploration work for placer gold was getting more attention and the profound works have been performed by A total of 173 placer deposits and occurrences of gold are known in the Adola area, comprising 7200 km 2 (EMRDC, 1985). In the Adola gold field, placer gold deposits with contents averaging 0.1 g/m 3 (of gravel) or more of gold and with gold reserves of over 30 kg are classified as “placer deposits”, while those with lesser gold values andGeology and mineral potential of Ethiopia: a note on
Primary and placer gold deposits are mined from the Pan-African Adola volcano-sedimentary sequence, in southern Ethiopia. Two major mineralized belts can be recognized: the Megado (‘Gold Belt’) and the Kenticha Belts. The Kenticha Belt is also known for its rare metal mineralization.Accordingly, the study area is located very close to the well-known Adola gold eld within the southern Ethiopia greenstone belt and there is an extensive artisanal mining activity by the localThe geology of the Lega Dembi gold deposit, southern

So far developed large scale gold mine in the country is the Lege-dembi gold mine, located in the southern greenstone belt region, being operated by private company with estimated reserve of 82 tons and an average annual production of 3.6 tons of gold. There is also small scale open pit mine of columbo-tantalite at Kenticha in the Placer gold was found in Adola belt 1936 and by 1996, had produced >55 t of placer gold.

Ethiopia’s only primary gold mines are Lega Dembi and Sakaro, both are located in southern Ethiopia in the Adola Gold Belt. Since commencing operations in 1998, Lega Dembi has produced 2.1 million ounces of gold. The remaining gold resource is estimated at 2.5 million ounces. Sakaro was designed as high-grade fill for Lega Dembi and has aGondiunnn Rcsrrrrcli, V. 2,No. 3, p p . 439-447. 0 1999 Iiiteriintioilnl Associcifioiifor ~ 0 i l d 7 i ~ ~ l l l ~ Rcscnrcli, Inpnii ISSN: 1.342-937X GR Gondwana ResearchGeology and Gold Mineralization in the Pan-African Rocks of the Adola

Important small scale alluvial gold mining sites in Cameroon are found in the Adamawa and East Regions, but other smaller active alluvial mining sites exist, among which is the Abiete-Toko Gold District where relatively little or no gold exploration has been undertaken (Embui et al., 2013; Soh et al., 2014; Vishiti et al., 2015, 2017).Moreover, The Ablarus and Epar gold mineralizations are and domains Haramsam, Hassamte and Chamuk gold prospect areas different parts of the country, particularly in Adola area of related to quartz mica schist and metagabbro, and the underlain by meta-granodiorite, amphibolites, gabbro- southern Ethiopia since the Italian aggression during Gold in Ethiopia-Mining PDF Scribd
