Common Problems Found in Underground Mine Plan Audits

Published on May 15th, 2020

Senior Mining Engineer, Tom Joseph provides a short audio presentation on cut-off grade calculation and cost estimation, two of the most common problems in mining.

He touches further on the importance of reviewing the cut off grades yearly whilst outlining some of the misunderstandings in cost estimates that can make a sub-optimal mine plan look feasible.

Join us in our latest audio presentation as we explore some of the common problems found in short to medium term plans and discuss how to look for problems that stop us from achieving maximum benefit.
