The development of the Calcario Limestone Project is a strategic component of Verde’s fertilizer production strategy. The production of ThermoPotash requires significant quantities of limestone as one of its raw materials. It requires high quality limestone, having CaO content higher than 50% with associated SiO2 lower than 2%.
In June 2011, Verde reported the discovery of a major high grade limestone unit located approximately 100km from the Cerrado Verde Potash project in Minas Gerais State, Brazil and in September 2011, the Company received an independent resource estimate. The resource includes 89 million tonnes in the indicated category at an average grade of 54.71% CaO and 180 million tonnes in the inferred category at an average grade of 54.7% CaO (no cut-off applied).
