Model to Metal Reconciliation: Delivering on Promises

Simulated orebodies can be sampled using various grade control strategies and these notional grade control samples used to predict outcomes. In particular, the Chain of Mining (CoM) method (Shaw and Khosrowshahi, 2002) can be used to assess how sampling, grade control, mining selectivity and blasting practices impact reconciliation variances.
