The thickness of gypsum layer is of some 20 m and corresponds to a gypsum level known as the First Mass The stratigraphic series is then completed by supra and infra gypsum marl formations as well as by three other levels of gypsum see Fig 1 The mine spans roughly 50 ha and is operated using the method of rooms and pillars
About one billion tons of gypsum deposits are spread over many sites in Nigeria The quality of gypsum is a function of the calcium sulphate CaSO4 content The higher the calcium sulphate CaSO4 content the higher the grade and price This report seeks to examine the financial viability or otherwise of mining gypsum rock in Nigeria
