Magnetic (Mag) Survey Services
High-resolution magnetic data that accelerates discovery and reduces drilling risk.
Magnetic surveys (mag surveys) are one of the most powerful tools available to modern exploration teams. By measuring subtle variations in the Earth’s magnetic field, these surveys reveal the geological structures, lithologies, and intrusions that control where mineral deposits form.
If you need fast, reliable insight into the subsurface without the high costs of drilling, magnetic surveys are one of the smartest ways to move your project forward.
Rangefront delivers complete magnetic survey solutions, from planning and data acquisition to processing, modeling, and interpretation. Our services help exploration teams make confident decisions, prioritize drill targets, and understand their project’s geological framework with much greater clarity.
Why Magnetic Surveys Matter
Magnetic surveys allow you to map geology at scale, quickly and affordably. They’re often the first step exploration companies take when evaluating new ground because they offer immediate insight into what’s happening beneath the surface.
Magnetic data can reveal features such as mafic and ultramafic intrusions, iron formations, fault networks, shear zones, basement topography, and alteration zones where magnetic minerals have been added or removed. These geological clues often point directly toward areas with the highest mineral potential.
Ultimately, magnetic surveys save time, reduce cost, and help exploration teams avoid drilling blind.
What We Offer
Rangefront provides Rangefront provides airborne (manned aircraft or drone/UAV) and ground magnetic surveys, each tailored to your project scale, terrain, and exploration goals. Our teams handle every part of the workflow, from designing the survey and collecting high-quality magnetic data to delivering clear, meaningful interpretation. You receive more than data; you receive actionable geological insight.
Drone Magnetic Surveys
For target areas, rugged terrain, or infill after a regional program, drone magnetic surveys (UAV magnetics) provide a fast, high-resolution way to tighten up targets. Drones fly low, controlled flight lines while collecting continuous magnetic measurements, often with tighter line spacing than conventional airborne surveys and with minimal ground disturbance.
This gives you a detailed map of:
-
Structural trends and fault zones
-
Subtle lithologic contacts and domain boundaries
-
Intrusions and alteration-related magnetic signatures
-
Extensions of known anomalies beneath cover
-
Iron-rich formations and magnetic highs/lows that guide targeting
Drone magnetics helps turn broad regional anomalies into drill-ready targets before ground work ramps up.
Ground Magnetic Surveys
Once regional anomalies or target areas are identified, ground magnetic surveys provide the high-resolution detail needed to refine drill targets. Using precise walking magnetometers, our crews collect closely spaced measurements that offer a much more detailed picture of geology at the project scale.
Ground magnetic surveys excel at:
-
Identifying subtle faults or cross structures
-
Delineating intrusive contacts and mafic units
-
Detecting small iron-rich bodies or skarns
-
Improving structural interpretation
-
Pinpointing drill collars with confidence
This level of granularity helps exploration teams reduce the risk and cost of drilling.
Airborne Magnetic Surveys
For large land packages or early exploration phases, airborne magnetic surveys are the fastest and most cost-effective way to understand regional geology. Aircraft follow tight, controlled flight lines to capture continuous magnetic measurements across your entire project area.
This gives you a detailed map of:
-
Structural trends
-
Intrusions and plutonic bodies
-
Iron-rich formations
-
Lithological domains
-
Basin architecture and depth to basement
Airborne magnetics helps narrow down broad areas into focused zones where ground-based work and drilling should begin.
High-Quality Data & Process Modeling
Magnetic data is powerful—but only when processed correctly. Our geophysicists apply all necessary corrections and enhancements, producing clean, stable datasets that are ready for interpretation or integration into 2D and 3D geological models.
We deliver:
-
Total magnetic intensity maps
-
Reduced-to-pole (RTP) transformations
-
Derivative grids and analytic signal maps
-
Lineament interpretation
-
Structural and lithological models
-
Drill-targeting recommendations
Every deliverable is designed to support smarter exploration decisions, not overwhelm you with unnecessary complexity.
How Magnetic Surveys Fit into your Exploration Program
Magnetic surveys can add value at almost every stage of exploration. In early phases, they help you understand the geological setting and identify promising trends. At the project scale, they refine anomalies and highlight specific structures or lithologies to target. In later stages, magnetic data feeds into 3D models that support resource delineation and technical reporting.
Whether you’re building a first-pass picture of your project or tightening up drill targets, mag surveys help move exploration forward with clarity.
