The Science Behind Magnetometer and Resistivity Surveys in Mining

1. What is a Magnetometer Survey?

A magnetometer measures the Earth's magnetic field and detects variations caused by the presence of magnetic minerals like magnetite, pyrrhotite, or even buried metal objects. These subtle magnetic anomalies help geologists create a magnetic map of the subsurface.

• How it works:
• It detects variations in magnetic intensity. By comparing these readings with the baseline Earth’s magnetic field, explorers can pinpoint mineral-rich zones.
• Use in Mining:
• Ideal for identifying ferrous mineral deposits and structural geology like faults or dykes. It’s non-invasive and provides fast, accurate results.

2. What is a Resistivity Survey?

Electrical resistivity is a method where electrical current is passed into the ground, and the resistance to that current is measured. Different rocks and minerals conduct electricity differently, making it possible to map underground structures.

• How it works:
• Electrodes are inserted into the ground to measure how easily current flows between them. Moisture content, mineral composition, and porosity affect resistivity readings.
• Use in Mining:
• Perfect for locating water-bearing formations, sulfide mineralization, and identifying ore bodies. It complements magnetic surveys by offering data about non-magnetic materials.

3. Complementary Nature of Both Surveys

When used together, magnetometer and resistivity surveys provide a complete geophysical profile. While magnetometers detect metallic and magnetic anomalies, resistivity surveys reveal the electrical nature of the subsurface. This combo allows mining teams to reduce guesswork, optimize drilling locations, and minimize environmental impact.
