"Exploration for residual Tertiary/Quaternary lateritic bauxite developed
on Archaean granitic and gneissic basement. Scout drilling along
forrestry tracks and areas selected visually on the ground and from
monochromatic aerial photographs disclosed a wide variation in ore
thickness and grade. 2368 holes for 6891 metres were drilled to an average depth of 2.9 metres leading to an estimation of 25.5 million tons of bauxite of an average grade of 34% available alumina.

Once again thanks to pattyp for the research, keep up the good work!

by the way Tibbs he's still got no luck with his account.
