Aeromagnetic Surveys

High-sensitivity fluxgate and cesium vapour magnetometers deployed on fixed-wing and multi-rotor platforms for mineral exploration and structural geology.

Mineral Exploration≤2 nT Resolution1,000m Depth
TECHNICAL OVERVIEW

Sub-Surface Mineral Intelligence at Scale

Aeromagnetic surveying measures subtle variations in the Earth's magnetic field caused by differences in the magnetic susceptibility of crustal rocks. Our cesium vapour magnetometers achieve ≤2 nT sensitivity, enabling detection of magnetic anomalies associated with iron ore bodies, massive sulphide deposits, kimberlite pipes, and magnetite-bearing host rocks at depths exceeding 1,000 metres.

The Arabian Shield — one of the world's most prospective greenstone belts — contains significant undiscovered mineral wealth. Our aeromagnetic surveys provide the first-pass exploration intelligence needed to rank target areas, design drilling programs, and advance projects from reconnaissance to resource definition.

PLATFORM SELECTION · 1,200 KM² REFERENCE BLOCK

Three platforms. One target. Different physics.

We size the platform to the target. For shallow-to-mid-depth concessions a drone fleet runs faster and cheaper. For deep targets or large regional blocks the heavy-lift drone or helicopter earns its overhead. The numbers below reflect the same 1,200 km² block flown by each platform.

P-01

Drone fleet

PRIMARY · Shallow to mid-depth
Effective depth300 m
Sensor noise floor0.005 nT/√Hz
Along-line resolution0.1 m
Total project duration107 days
Mobilization4 days
Permitting (typical)14 days
Crew size5 persons

Two drones run mag+rad and AEM packages in parallel.

P-02

Heavy-lift drone

UPGRADE · Deep targets, gradient
Effective depth600 m
Sensor noise floor0.0002 nT/√Hz
Sensitivity vs drone10× better
Total project duration96 days
Mobilization7 days
Permitting (typical)21 days
Crew size6 persons

True gradiometer eliminates diurnal drift — helicopter-grade resolution at drone overhead.

P-03

Helicopter

REGIONAL · >5,000 km² blocks only
Effective depth1,000 m
Sensor noise floor0.001 nT/√Hz
Along-line resolution0.5 m
Total project duration184 days
Mobilization25 days
Permitting (typical)90 days
Crew size8 persons

Mob and permit overhead amortizes only at >5,000 km². Below that, drones win on every axis.

Reference block: 1,200 km² mag+rad combined, 1,100 km² AEM, KSA. Numbers reflect mobilization → final report including permitting, field execution, processing, and interpretation.
