HELICOPTER MAGNETICS AND RADIOMETRICS

NRG’s Xplorer™ system delivers ultra-high-resolution helicopter-borne magnetic and radiometric surveys, optimized for rugged terrains and complex geological settings. Utilizing dedicated low-noise aircraft, advanced sensor configurations, and high-speed data sampling, Xplorer™ ensures superior data quality. Its low-altitude operations enhance anomaly detection and structural mapping, making it ideal for mineral exploration and environmental monitoring 

Key features of the Xplorer™
system include:

Integrated
System Design

Combines magnetic and radiometric sensors in a cohesive system, streamlining data acquisition and enhancing survey efficiency.

Low-Altitude
Flight Capability

Operates at reduced survey heights with excellent terrain following capabilities, enhancing high-frequency content and improving anomaly definition in challenging environments.

Gradient-Enhanced
Magnetic Data

Employs horizontal gradient measurements to refine spatial positioning and resolve line-parallel features with greater accuracy.

High-Speed
Data Sampling

Magnetic data and DGPS sampled at 20 Hz, capturing short-wavelength anomalies effectively.

Full-Spectrum
Radiometric Analysis

Utilizes up to 2048 in³ NaI crystal packs with Radiation Solutions spectrometers for detailed gamma-ray spectrometry.

Enhanced
Signal-to-Noise Ratio

Low-altitude flights and slower speeds improve signal clarity, resulting in a down-line sample window of approximately 20 meters.

Robust Helicopter Platform

Deploys powerful ASTAR B-series helicopters equipped with non-magnetic composite horizontal-boom mountings for stability and minimal interference.

Advanced
Data Processing

Applies full spectral NASVD processing to all radiometric data, ensuring high-quality outputs for geological interpretations.

Versatile Geological Applications

Effective in mapping alteration zones, identifying surficial uranium mineralization extents, and prioritizing various mineral deposit targets.
