Abstract
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 3640& 3700 and Latitudes 2045& 2115 N with an area of about 11.5 Km 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 20X40m 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 m which represent the geological reserve, with average gold grade 0.30g/ m.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 m\hr to 6 m\hr and combinely the total production of the operational boreholes about 75 m/hr.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
