New magnetic data. New exploration targets. 🧲

A recent magnetic survey at Yukon Metals’ AZ Copper-Gold Project in Yukon has highlighted a previously untested convergence zone.

The 400-line-km survey used a GSMP-35U potassium-vapour in a UAV towed-sensor configuration, with 25 m line spacing.

The resulting magnetic data identified two intersecting structural trends that converge in an area associated with elevated copper values and surface mineralization.

It’s another great example of how high-resolution magnetic surveys can help geologists refine the geological picture and identify areas for follow-up exploration.

From the field to the final map. 🧲

What happens after a magnetic survey is completed?

1️⃣ Collect — A magnetometer records measurements across the survey area.

2️⃣ Process — The data is corrected and cleaned to remove effects such as diurnal variation and other sources of interference.

3️⃣ Map — The measurements are transformed into detailed magnetic maps that reveal patterns and anomalies.

4️⃣ Interpret — Geophysicists combine the magnetic data with geology and other information to understand what may be happening beneath the surface.

The magnetometer is just the beginning. It's the quality of the data—and how that data is interpreted—that turns measurements into meaningful exploration insights.

Take VLF surveys to the air. 🛩️

What if you could use Very Low-Frequency ( ) EM to investigate the subsurface in areas where traditional ground or manned airborne surveys are difficult?

The GEM Systems -VLF combines VLF electromagnetic surveying with UAV technology, allowing operators to efficiently map resistivity contrasts, geological contacts, faults, and conductive structures—even in challenging terrain.

With two lightweight VLF sensors, the system can simultaneously measure signals from two selected VLF stations while collecting detailed in-phase, out-of-phase, and horizontal field data.

From mineral exploration and bedrock mapping to water exploration and pipeline detection, the UAV-VLF opens up new possibilities for electromagnetic surveying.

UAV VLF-EM SYSTEM: Resistivity Mapping Solution | The Very Low-Frequency (VLF) Electromagnetic Method (EM) survey technique is a passive method that utilizes distant, globally positioned transmitters that are broadcasting at frequencies in the range of 15.0 – 30.0kHz. In a VLF investigation the primary fields (generated by the radio transmitters)...

At Vault Strategic Mining's War Bond Tungsten Project in Nevada, a high-resolution UAV magnetic survey is underway to help refine the geological picture and identify priority exploration targets.

The roughly 70 line-km survey is using tightly spaced flight lines to map magnetic features, structural trends, and geological contacts that may be associated with tungsten-bearing skarn and tactite mineralization.

The equipment used includes a GEM Systems GSMP-35U potassium vapour magnetometer ( ) and a GSM-19 Overhauser base station.

It's a great example of how modern UAV magnetics can complement geological mapping and sampling—helping exploration teams build a more detailed picture of what's beneath the surface before drilling.

Why do exploration teams start with magnetic surveys?

Magnetic surveys are often one of the first steps in understanding what's beneath the surface.

They can help geoscientists:
🧲 Map geological contacts and rock types
🧲 Identify faults and structural trends
🧲 Delineate intrusive bodies and d***s
🧲 Refine exploration targets before drilling
🧲 Build a better understanding of regional geology

While magnetic data doesn't identify minerals on its own, it provides valuable context that helps guide exploration decisions and reduce uncertainty.

That's why magnetics continues to be one of the most widely used geophysical methods in mineral exploration.

Precision matters—especially when you're measuring the Earth's magnetic field.

The CONRAD Geomagnetic Observatory was designed to push the boundaries of geomagnetic research. Equipped with three GEM Systems SuperGradiometers, the observatory is capable of measuring magnetic field gradients in the femtotesla (fT) range, enabling researchers to study subtle variations in the Earth's magnetic field with exceptional sensitivity.

By combining north-south, east-west, and vertical gradient measurements, the observatory supports advanced research into geomagnetic processes and their effects on our planet—demonstrating what's possible when cutting-edge instrumentation meets scientific discovery.

Sometimes, the best way to understand what's below the surface is to get boots on the ground.

Bronco Resources recently announced the completion of a ground magnetic survey at its Placer Mountain Gold Project in British Columbia using the industry-standard GSM-19 ground magnetometer. The survey produced higher-resolution magnetic imagery than previous airborne data, revealing structural trends and magnetic lineations that could be associated with gold-bearing zones. Based on these results, the company is expanding its ground magnetic program to further refine exploration targets.

It's another great example of how high-resolution ground magnetics continues to play an important role in modern mineral exploration—helping geoscientists build a clearer picture of the subsurface before drilling begins.
