The major
theme of the present study is to determine total potential of alluvial gold
reserves in wadi Gebeit and some of its tributaries (Wadi East and West Gebeit)
within the area of the study area as indicated is located between Longitudes 36040’&37000’
and Latitudes 20045’&21015’ N with an area of about
11.5 Km² approximately. The area as a whole is part of Arabian-Nubian Shield.
Geologically it consists of Proterozoic rocks of Nafirdeib series; volcanic and
volcano-sedimentary rocks cover the terrain. These rock types have been
subjected to regional metamorphism to green schist facies, folding and faulting.
These were later reworked by the invading gold bearing hydrothermal solutions
that now exist as quartz lodes, veins, vein-letsand their alteration zones as
primary gold.
The study
of stream sediments gold evaluation a systematic grid sampling is done by
digging pits of 20X40m² all over the selected area in wadi Gebeit and its
terbutaries. All stream sediments in the area are highly over turned by the
artisanal using dozers, excavators, and loaders. These tools are destroyed the
geological features of the area and mixing the weathered bed rocks with the
overlain soil. The total volume of the studied stream sediments is711,692 m³
which represent the geological reserve, with average gold grade 0.30g/ m³. The
gold reserves in the study area are230 kilograms, of fine and medium grains. The
ground water resources availability is restricted in wadi
Gebiet and Adalaweib. Pumping test reveal that the production of the boreholes
varies from 4 m³\hr to 6 m³\hr and combinely the total production of the
operational boreholes about 75 m³/hr.
