Down Hole Logging
Natural Gamma
For general lithology and to calculate a Uranium resource.
Magnetic Susceptibility.
For identifying Fe minerals - magnetite, pyrhotite and hematite.
Resistivity and Induction Conductivity.
Used in groundwater and mineral investigations.
Gamma Gamma Density.
Gamma Gamma Density uses a radioactive source. For obtaining density of material in grams per cubic centimetre. This is useful when calculating a resource for mining. Gamma Gamma Density detects material such as coal which is less dense than the surrounding rock.
Gyro Tool (Reflex)
Used to determine sub-surface drillhole location.
