Material accounting, not stock counting
Mining operations move mass. Extraction, hauling, processing and dispatch all change the form and the value of that mass, and each step introduces measurement variance. A system that only counts units cannot express any of this.
Haulage is where the money goes
Distance from face to plant, load factor, fuel efficiency and tyre wear determine haulage cost, and most operations only see the fuel bill in aggregate at month-end. Costing per vehicle and per trip changes decisions about fleet mix and route planning almost immediately.
Royalty and permit reconciliation
Royalty calculated on production estimates rather than measured dispatch is both a compliance exposure and, frequently, an overpayment. Permit consumption tracked as material moves keeps statutory returns defensible.
Equipment availability is the real constraint
Excavators, loaders and crushers determine throughput more than reserves do. Preventive maintenance scheduling and breakdown history make availability something you manage rather than something that happens to you.
Site-level truth
Groups running several pits need per-site profitability. Averaged across the group, a loss-making pit is invisible until someone looks specifically.
