IMC employed a three step process to estimate the volume of saleable sand stocks across CFSM mining lease. Firstly, using lidar data, IMC developed a complete 3D digital terrain wireframe of the entire deposit to model the potential sand resources. Secondly a site visit was organised to validate the lidar data and measure significant geological contact zones. Finally, IMC provided practical recommendations to the client on how the estimated sand endowment could be converted to a JORC compliant resource statement.
