Benches, stockpiles and haul cycles surveyed every shift without stopping the pit. The dock launches on the clearance horn, the surface lands before the muckpile is touched, and month-end becomes a reconciliation instead of an argument.

The sheet above is a drawing of this. 10 capture waypoints, and every finding called as the aircraft reaches it — scroll sets the target, the mission keeps its own pace, and the page waits for it.
Month-end is a survey crew walking a cone of ore and an accountant taking their word for it. The number moves six per cent between two people measuring the same pile, and the auditor asks which one is right.
Stockpiles closed at month-end
Every stockpile on the ROM pad is surfaced from the same flight the benches came off, differenced against the pad base surface and reconciled to ±1.8%. The tonnage carries the survey behind it.
A survey crew on a bench is a stopped bench. Nobody schedules that at 06:00, so the pit gets flown when it suits the day rather than when the shift changes — and the record drifts a week behind the dig.
Capture that never stops the pit
A dock on the crest launches on the clearance horn and lands before the excavator swings again. Twelve pits, two captures a day, no pilot in a truck and no bench standing idle for either of them.

The fleet plan says a 21-minute cycle. The ramp says otherwise after the third re-route, and the first anyone hears about it is when the tonnes do not land at the crusher.
Haul cycles measured, not estimated
Ramp geometry comes off the same surface as the benches and truck positions off the fleet feed, so the real cycle reads 24 minutes — and the idle iron sitting outside it is named, not averaged away.
The program runs on the pit's own clock — the clearance horn, the shot, month-end. Nothing on this list asks the pit to stop; everything on it lands on the same record.

Dock flight
2×/day, launched on the clearance horn
A dock on the crest flies the benches, the ramp and the ROM pad, and is back on its pad before the excavator swings again. Every shift ends with a surface, not an estimate.
Each pile on the ROM pad is differenced against the pad base surface from the same flight the benches came off. The tonnage carries the survey behind it into the close.
The pre-blast surface is flown in the clearance window and the muckpile is differenced 26 minutes after firing — 62,000 t read against design before a bucket touches it.
Truck positions land on the same surface the ramp geometry comes from, so the haul cycle is measured against the ramp as it is — and the idle iron outside it is named.
No. The dock on the crest launches on the clearance horn and lands before the excavator swings again — no pilot in a truck, no bench standing idle, two captures a day across the operation.
Fourteen stockpiles on the ROM pad, differenced against the pad base surface from the same flight the benches came off, reconciled to ±1.8%. The auditor gets a survey, not two people's word.
How accurate is the surface — and do we lay control every flight?
The fix holds to ±1.2 cm, repeatable flight to flight, at 2.4 cm detail on the ground. Control is laid once and checked, not rebuilt every morning.

Q04
Can one record hold the whole group, not one pit?
Twelve pits, captured every shift, on one record. The planner in pit 3 and the board read the same surfaces and the same stockpile ledger, cut to their own morning.

Q05
How fast is a shot on the record?
Cleared at 12:40, fired at 13:00, muckpile differenced at 13:26 — twenty-six minutes from shot to volume, with 62,000 t read against design before the muckpile is touched.

Q06
What happens when the ramp changes?
Ramp geometry comes off the same surface as the benches, so the fleet plan meets the ramp as it is: the real cycle reads 24 minutes against a 21-minute plan, and the difference is named, not averaged away.

Q07
How much is left to dig to design grade?
Current terrain set against the designed pit shell, zone by zone. Bench 4 reads 1,240,000 m³ of cut still to grade at ±1.8%, so the mine plan is a countdown in cubic metres rather than a date on a chart. Material class comes from your own block model, which means every zone's measured volume carries the class you already assigned it.

Who reads it
Read overnight on a pit like this one: two dock flights, the stockpile ledger, the fleet feed, and the design shell at its current revision. Three of the 27 profiles wake up to it.
The 13:00 shot gates bench 4: hold the dig on the east face until the pre-blast flight lands, and the 62,000 t reads against design by 13:26.

HAZARD
Nobody walks a bench to prove the pattern is clear — clearance reads off the 12:52 flight, and the ramp's 10% grade is checked from the same surface, truck by truck.
Send us a pit boundary and the design shell — we will fly one shift's capture and hand you the bench surfaces, the stockpile ledger and the reconciliation.
