Introduction In open-pit nickel mining, the transition from geological resource estimation to economic pit optimization is a critical workflow that […]
Multiple case studies follow the same sequence: This integrated loop is reported for gold, copper–cobalt and other deposits, with the […]
The literature distinguishes clearly between economic cut‑off grade (COG) used for mine planning/operation and geological cut‑off grade used to report […]
Open‑pit design always comes to a critical question: how big should the final pit be? This “ultimate pit” decision controls how much […]
This post describes an optimization technique where you create the CONC attribute (concentrate) to be valued and allow for a pit optimization based on this variable in GEOVIA Whittle.
