Mine site intelligence — captured monthly, reconciled defensibly.

From pit progress to stockpile reconciliation, haul-road condition to rehabilitation reporting — drone LiDAR turns the mine site into a measurable, repeatable dataset. Captures take hours, not weeks, and never stop the trucks rolling.

Interactive · Monthly reconciliation

Step through four monthly captures of an evolving pit.

Each capture is geo-referenced to the same survey control, so the difference between any two surfaces is a deterministic number — not an estimate. The volume bar tracks against the annual plan; the period delta is what the mine planner reports to the General Manager at month-end.

Repeatable monthly capture. Each LiDAR pass is geo-referenced to the same control, so reconciliation becomes deterministic — the difference between two surfaces, not an argument between two spreadsheets. Schematic shown at 1 svg unit ≈ 2.6 m; real captures resolve to ±20 mm vertical.

The problem

The cost of capturing a mine the hard way.

Reconciliation cycles are slow, capture is dangerous, and the data that drives the decisions is rarely fresh. Traditional survey methods compete with operations for site access and rarely keep up with the production pace.

  • 01 · GPS-walked stockpiles are guesswork

    A surveyor walking a stockpile gets a handful of breaklines and a base ring — the volume that drops out depends on the assumed base plane more than the pile itself.

  • 02 · Pit progress lags reality

    Monthly reconciliation that arrives three weeks after month-end is operationally useless. Decisions have already been made on stale numbers, and corrections are after-the-fact.

  • 03 · Crews on unstable batters

    Surveying a pit floor or a fresh dump face puts personnel inside the operational footprint. Every capture adds exposure — for data that&apos;s already going stale by the time it&apos;s plotted.

  • 04 · Reconciliation arguments cost the project

    When the mine plan, the geological model, and the surveyor&apos;s spreadsheet all disagree, the project pays for the argument — in delayed claims, contested invoices, and lost confidence in the numbers.

Why LiDAR

One surface, captured monthly, runs the whole site.

Drone LiDAR captures the full operational envelope — pit, dumps, haul roads, ROM, WROM and stockpiles — in a single mobilisation, without stopping operations or sending crews onto live faces. Every surface is geo-referenced to the same control. Every month after that is a deterministic comparison.

  • Audit-grade stockpile volumes

    Full surface capture of every stockpile to ±1.5% volume accuracy, with the base plane derived from prior captures or design — not assumed.

  • Pit progress, monthly or weekly

    Same flight plan, same control, every capture. Bench advance, depth progression and material moved drop out as a deterministic comparison.

  • Haul-road condition profiling

    Roll, crossfall, rut depth and water-pooling risk derived from the same LiDAR pass. Maintenance prioritisation moves from operator complaint to engineering data.

  • Dump and TSF stability monitoring

    Change detection on dump faces and tailings storage facilities flags batter creep, settlement and freeboard loss between captures.

  • Rehabilitation reporting that holds up

    Pre- and post-rehabilitation surfaces with batter angles, surface roughness and revegetation cover — ready for closure reporting and regulator submission.

  • Capture without halting operations

    Drone airspace is segregated from the haul fleet. Captures run above active operations with no production interruption and no personnel on unstable ground.

Workflow

A standard monthly reconciliation capture.

  1. 01
    Establish baseline

    First capture sets ground control, flight plan, surface model and reconciliation baseline. Subsequent captures re-use all of it.

  2. 02
    Capture

    Single-mobilisation drone flight covering pit, dumps and stockpiles. Airspace coordinated with site SSE. No production interruption.

  3. 03
    Process & QA

    Trajectory correction, classification, control validation. Independent QA against prior capture before any delivery.

  4. 04
    Reconcile

    Surface differencing, stockpile recompute, dump comparison. Signed reconciliation pack lands in technical services within 48 hours.
