Measuring a stockpile is one thing. Explaining why volumes changed, why numbers did not match across systems, and what finance, audit, royalty, JV, or regulatory stakeholders needed to see was another.
In this session, we walked through a stockpile reconciliation framework operators can use to connect what is measured in the field with what is reported in the books. We covered the key comparisons every site can run, how survey cadence affects confidence, and the common variables that create reconciliation drift, including shrink and swell, density assumptions, tonnes versus cubic metres, material movement, and rehandles.
You’ll come away with a repeatable process for reducing end of month surprises, building trust in inventory reporting, and creating a defensible audit trail for the stakeholders who rely on your stockpile numbers.
Who this session was for
Operations leaders, site managers, inventory and production teams, survey teams, technical services, finance stakeholders, and anyone responsible for stockpile confidence, reconciliation, or reporting.
