Mine-to-Mill Reconciliation

What this topic covers

Compare geological estimates, mined ore and plant measurements.

Core mine-to-refinery ideas

Reconciliation tests whether predicted tonnes and grade match what is actually mined and processed.

Persistent differences can indicate geological, sampling, survey or ore-control issues.

Good reconciliation improves planning and confidence in metal forecasts.

Important tradeoffs

Throughput alone is not a useful measure without grade, recovery, availability, water and energy context.

Measurement and accounting

Control systems support qualified operators and should use defensive industrial cybersecurity practices.

Lifecycle perspective

Maintenance and hazardous-work procedures are intentionally excluded.
