Contract Magnetic Exploration Services

Groundsearch provides contract magnetic survey services across Cambodia and the wider region, for mineral exploration, geological structure mapping, unexploded ordnance (UXO) screening, and locating buried infrastructure. Surveys are scoped to the target and terrain — ground-based, drone-mounted, or a combination — and delivered with processed anomaly maps your team can act on.

What magnetic surveys are used for

  • Mineral exploration — mapping magnetic anomalies associated with ore bodies, intrusions, and structural targets before committing to drilling
  • Geological structure mapping — identifying faults, dykes, and lithological contacts not visible at surface.
  • UXO and buried metal detection — screening sites for unexploded ordnance or buried infrastructure ahead of construction or land clearance.
  • Archaeological and heritage survey — non-invasive detection of buried features.

How a magnetic survey works

  • Scoping — define the target (ore body, structure, buried object), site access, and required resolution.
  • Survey design — set line spacing, sensor height, and ground vs. airborne approach based on the target depth and size.
  • Data acquisition — field survey using GSM proton GEM 300 - (pair rover and base)
  • Processing and interpretation — anomaly mapping, filtering, and integration with existing geological data.
  • Reporting — a clear deliverable your team can use to target follow-up work (drilling, excavation, further survey).
