    17, 2016018332Exploration of this bauxite district started in 1939, while mining commenced in 1941. The district originally consisted of 13 bauxite deposits, several of which are currently mined out. The original reserves of 100 Mt were based on a cutoff grade of Fe 2 O 3 lt 30% and TSiO 2 lt 15%.

  • Drill Results Apparent Versus True Thickness Geology

    17, 2019018332In geology, the thickness of the feature observed by drill 1 is called an apparent thickness, because it varies from the true thickness of the feature. An apparent thickness will give the illusion that a larger amount of the resource has been found than is actually present. That is why for resource estimates only true thickness is used.
