First Bauxite Corp. has a mining permit from the Guyana Geology & Mines Commission to mine bauxite at a general location called Bonasika, located on the right bank of the Essequibo River
-
An environmental permit is held · The bauxite deposits are usually tabular with the typical thick interiors and pinched dipping marginal terminations described as “Turtlebacks”
-
The typical vertical profile consists of 3 to 35 feet of overburden consisting of white sands, aluminous clays and occasional loams overlying 6 to 34 feet of bauxite
-
The Bonasika deposits were churn drilled by the Demerara Bauxite Company (Demba) on a square grid pattern using 600 feet center; GINMIN has copies of the drill logs and has drilled some confirmatory drill holes of its own
-
Using a cutoff of 20% SiO2, 7% Fe2O3 and a minimum of 50% Al2O3, GINMIN has calculated the drill indicated geological reserves of MAZ bauxite at 5.2 million metric tons
-
Includes some 800,000 tons of Chemical Grade Bauxite (CGB)
