QUANTITATIVE ASSESSMENT OF LEAD–ZINC DEPOSIT THROUGH CORE –DRILLING AT IGIDAGU OKPITUMO AMACHI, ABAKALIKI LOCAL GOVERNMENT AREA OF EBONYI STATE

Abstract

The core drilling activities was a follow up of geological and geophysical exploration of the Exploration Lease (EL) over an area of land at above address acquired by Forward Gems and Earth Ltd, for quantitative assessment of the deposits of lead/zinc for economic viability. The core drilling exercise was used as a comparative studies and confirmative assessment of detailed reconnaissance survey, detailed geological and geophysical exploration already carried out on the acquired land. It is the third phase of the project. The samples analysis of the cores obtained was used to determine and reveal the physical and chemical nature of the rock underneath.The VES points where the core drill was carried out was chosen based on recommendation of geophysical/geological survey. However the survey report suggested that the lead mineralization faults/anomaly occurred in a deeper formation.
