Monthly Mine Stockpile Volumetric Survey Services in Mpumalanga, Limpopo & North West

Accurate month-end Run-of-Mine (ROM), crushed product, and discard stockpile reconciliation is mission-critical for collieries in Mpumalanga, chrome and PGM operations on the Eastern Limb in Limpopo, and platinum smelters in North West. TerraX3D provides rapid, SACAA-compliant drone LiDAR and RTK photogrammetry volumetric audits across South Africa's primary mining belts.

How accurate are drone volumetric stockpile surveys for South African mine audits?

When tied to dual-frequency RTK GNSS ground control checkpoints on the South African Lo coordinate grid (WG27, WG29, or WG31), UAV LiDAR and photogrammetry stockpile surveys achieve volumetric accuracy within 1% to 2% of true physical volume, fully satisfying JSE, SAMREC, and external financial auditor requirements.
