Ebonyi State, Nigeria 1. INTRODUCTION Enyigba is located within Ikwo and Abakaliki Local Government Areas of Ebonyi State on latitudes and and longitude and (Figure 1) and falls within the lower Benue sedimentary formation of southeastern Nigeria. The region is noted for Lead-Zinc mineral (Pb/Zn) mining activities by the locals.
Mississippi Valley-Type (MVT) ores are epigenetic, sedimentary hydrothermal base metal deposits that exist worldwide with type localities in the midcontinent United States. These Permian-aged sulfide ores represent an extraordinary concentration of economic metals, Pb and Zn. Ore deposits occur in vast districts that have a rich mining history. The Pb and Zn from …

Among these, the Sinemurian-Pliensbachian aquifer is currently the most productive carbonate horizon as it hosts most of the higher-grade orebodies, contributing up to 95 % of the total Pb-Zn-Ba production of the district. Uneconomic amounts of Pb Zn sulfides and barite occur as sparse cm-thick veins in the Paleozoic basement.
the Nigerian Mining Corporation has indicated proved reserves of up to 711,237 tonnes [5]. Nigerian Lead-Zinc Mining Company in 1956 gave conservative indicated reserves of 693,000 tonnes with 9.0% lead and 7.0% zinc [3]. The Abakaliki field is still Nigeria's most important lead-zinc deposit. In Azara area, the Nigerian Mining
