Mine Construction & Production Surveys

Purpose: To ensure all mine development and production activities are executed precisely to plan, maintaining safety and operational efficiency.

What We Do:

  • Establish survey control networks to guide construction crews.
  • Set-out of haul roads, pit boundaries, waste dumps, and plant infrastructure.
  • Verify excavation progress against design plans.

Deliverables:

  • Control point coordinates
  • Construction set-out maps
  • As-built documentation
  • Why It Matters: In mining, even small deviations can result in safety risks, over-excavation, or costly rework. Accurate set-out protects both assets and lives.

Exploration Survey Control

Purpose: To provide precise positioning for geological exploration and drilling campaigns.

Technology Used:

  • Set-out drillhole collars with high-precision GNSS.
  • Pick-up collar positions post-drilling for geological modelling.
  • Create control frameworks for mapping geophysical data.
  • Why It Matters: Incorrect drill positioning can compromise entire exploration programs. Our surveys guarantee accurate geospatial reference for all data collected.

Volume & Quantification Surveys

Purpose: To measure the quantity of extracted material, stockpiles, and waste dumps with pinpoint accuracy.

Technology Used:

  • UAV photogrammetry and LiDAR scanning of stockpiles.
  • 3D modelling to calculate volumes for inventory, reporting, and reconciliation
  • Comparative surveys to track production rates.

Products / Deliverables:

  • 3D models (TIN/point cloud)
  • Volume reports in CSV/PDF formats
  • Change-over-time visuals
  • Why It Matters: Accurate volumetrics are critical for mine planning, financial reporting, and contractual compliance.

Progress & Compliance Surveys

Purpose: To track the mine’s progress against design, budget, and regulatory requirements.

What We Do:

  • Routine monitoring of excavation faces, benches, and stopes.
  • Check against original pit or underground design models.
  • Provide proof of compliance with environmental and mining regulations.
  • Why It Matters: Helps avoid regulatory penalties, ensures design conformance, and enhances project transparency.

Blast & Drilling Set-Out, QA/QC

Purpose: To ensure blasts and drill patterns are accurately placed for maximum efficiency and safety.

Technology Used:

  • Set-out blast holes and drilling grids.
  • Post-blast surveys to assess fragmentation and displacement.
  • QA/QC reporting to improve subsequent blast designs.
  • Why It Matters: Reduces misfires, optimises fragmentation, and minimises risk to personnel and equipment.

UAV / Drone LiDAR & Photogrammetry

Purpose: To capture high-resolution aerial data for mine planning, monitoring, and safety inspections.

What We Do:

  • Fly UAV missions to capture orthophotos, DSMs, and dense point clouds.
  • Integrate aerial data with ground control for survey-grade accuracy.
  • Perform rapid inspections of high-risk areas without exposing staff to hazards.
  • Why It Matters: Safer, faster, and often more cost-effective than traditional methods—especially in remote or dangerous terrain.

Deformation & Monitoring Surveys

Purpose: To detect movement in mine infrastructure, slopes, tailings dams, and underground openings before failure occurs.

Technology Used:

  • Install and monitor prisms, extensometers, and inclinometers.
  • Perform high-frequency GNSS or total station checks.
  • Analyse and report movement trends for early warning.
  • Why It Matters: Prevents catastrophic failures, supports safety compliance, and protects lives.

Underground Mapping & Surveying

Purpose: To capture the geometry of underground workings for planning, safety, and legal reporting.

What We Do:

  • Traverse surveys through tunnels, drives, stopes, and shafts.
  • Laser scanning for 3D visualisation of underground spaces.
  • Integration of underground and surface datasets into a single mine model.
  • Why It Matters: Enables precise stope design, ventilation planning, and reconciliation between design and as-built mine workings.

Reclamation & Mine Closure Surveys

Purpose: To provide accurate data for rehabilitation and closure planning.

Technology Used:

  • Map disturbed land and waste facilities.
  • Survey reshaped topography post-rehabilitation.
  • Provide compliance documentation for environmental regulators.
  • Why It Matters: Demonstrates environmental responsibility, ensures legal compliance, and reduces liability post-closure.
