The Mine Planning and Survey Twin

This paper studies plan conformance at the point where an approved design becomes work at a bench, stope or development heading. It joins design surfaces and schedules to survey control, as-built geometry, geotechnical and hydrogeological restrictions, drill-and-blast conditions,...

The Economic, Legal and Regulatory Twin

This paper examines whether a mining value case is executable, rather than merely internally consistent. It relates controlled technical production and metal evidence to contract terms, payable-metal logic, price and FX versions, costs, royalties and tax where applicable, licence...

The Water, TSF, Geotechnical and Environmental Twin

This paper addresses high-consequence decisions involving water, tailings storage, geotechnics and environmental obligations. It connects instrument and survey provenance, water and deposition balances, freeboard, operational limits, trigger-action response plans, permit conditio...

The Haulage and Material Movement Twin

This study treats every movement of ore, waste or product as a potential change in material identity rather than as a dispatch transaction alone. It links loading origin, payload or scale support, route and road status, operator, time, destination, stockpile/dump state, rehandlin...

The Processing Twin

This paper investigates whether mine-to-mill recommendations remain technically defensible when laboratory evidence, feed identity, process measurements, instrument calibration and mass-water-metal accounting refer to the same controlled operating period. The Processing Twin test...
