Magnetic Surveys

Ground magnetic surveys

Map magnetic changes before committing to expensive targets.

WCP collects and processes ground magnetic data to help exploration teams map structures, contacts and magnetic responses that may deserve follow-up work. The method is fast, low-impact and useful when the target or host geology has a meaningful magnetic contrast.

What it can show

Magnetic surveys can outline changes in rock type, structures, faults and magnetic bodies beneath cover.

What it cannot prove

A magnetic anomaly is not proof of ore or gold. Results must be interpreted with geology, mapping, sampling and other project information.

Built around the decision

Start with the geological question, not the instrument.

We review the claim, target type, terrain and existing data before recommending line spacing or survey coverage. That keeps the work tied to a decision: where to map more closely, sample, trench, drill or stop spending.

How the work moves

A clear path from the first question to the final record.

  1. 01

    Design the grid

    Set survey lines and spacing around the target, terrain and required level of detail.

  2. 02

    Collect controlled data

    Run the field magnetometer with GPS control and a base station for daily magnetic changes.

  3. 03

    Process and map

    Correct and clean the readings, then prepare maps that make the response easy to compare.

  4. 04

    Interpret and deliver

    Explain the main patterns, limitations and practical follow-up targets.

Common questions

Before the work begins.

Can a magnetic survey find gold?

Not directly. It maps magnetic contrasts that may relate to geology or structures associated with a target.

Does the survey require line cutting?

Often no. Access and vegetation determine the practical field layout, and we design the survey to minimize disturbance.

Where does WCP work?

WCP works worldwide, with most projects in British Columbia and Yukon and completed work in Africa, Mongolia and the United States.
