The Mineral Industry of Mali in 1998

Gold production exploitation permits at Loulo and Sadiola included Afko Corp. from the Sadiola Hill Mine, the Syama Mine, and artisanal Mali, a subsidiary of Afko Korea Inc., on a Kéniéba area production reached an estimated 25 metric tons. Mali was tied property and African Goldfields Corp., a subsidiary of African for third with Zimbabwe on the list of African gold producers, Selection Mining Corp. of Canada, on the Kofi and the Metedia after South Africa and Ghana.

For example, a deadline to apply for a scholarship can be easily missed if it is not posted to the community at a proper time. As a result, and for better and faster communication among the geological society of Africa, the GSAf will use a Gmail group ([email protected]) to facilitate the communication between society members. Some advice and rules: Since any member can post and all the members will receive your message, please do not overload the society by un-related news. Post only important news that wants immediate action from members. Improper messages can lead its owner to be blocked from posting. -

Gold in Mali
Acta Montanistica Slovaca Ročník 4 (1999), 4, 311-318 Gold in Mali 1 Imrich Kušnír Zlato v Mali Článok sa, okrem stručného úvodu do geológie regiónu, zaoberá popisom hlavných zlatých ložísk Mali, kde sa t.č. ťaží viac ako 20 t zlata ročne. Súčasné objavy zlata v tejto Západoafrickej krajine sú totiž príkladom, ako orientácia geologického prieskumu územia s dobrým potenciálom pre určitú nerastnú surovinu a použitie vhodnej metódy môže viesť k úspechu. Zlato sa v Mali ťaží už od nepamäti, ale ekonomicky významné ložiská (s prepočítanými zásobami 50 až 240 ton Au), sú objavované len v poslednom období. Presnejšie odvtedy, odkedy sa prieskum sústredil na zóny proterozoických epimetamorfovaých vulkano-sedimentárnych hornín (tzv. Birrimian greenstone belts) Západoafrického kratónu, s použitím geochémie, ako jednej z hlavných prieskumných metód. Keď si prieskumári uvedomili, že "Birrimian" môže mať rovnaký potenciál na zlato ako archaické "greenstones", ktoré sú hlavným zdrojom zlata na svete a že geochémia môže byt účinnou metódou pre prieskum krajiny s plochým povrchom, bez východov hornín, ktorá je charakteristická pre väčšinu územia Mali (a celej Západnej a Strednej Afriky). Key words: Mali, West Africa, West African craton, Tuareg shield, Proterozoic, Birrimian, Pan-african orogeny, precambrian greenstones, gold, lode gold, auriferous tourmalinites. Introduction Gold mining in Mali has a long history. In 1433, its renowned emperor Kanku Mussa brought 8 tons of gold on his pilgrimage to Mecca. Local population has exploited gold since immemorial times. Nowadays, several thousands of "artisan" miners exploit numerous sites and their production is estimated at more than 2 tons of gold per year. Industrial mining began in the 1970's (Kalana mine), following a large exploration programme by SONAREM with the soviet assistance (Golder et al., 1965; Boltroukevitch, 1973). -

Among Birimian structures, N-S and NE-SW trends have been defined as controlling gold mineralizations in Kedougou-Kenieba Inlier (KKI), whereas some of these structures are not gold-bearing. To determine structures related to gold mineralization, airborne electromagnetic data collected during the “Système Minier” of Mali have been processed and interpreted. Identified lineaments have been followed in the ground to establish their link with gold showings in the Kenieba area. -
