Golder Associates offers a broad range of geophysical services to the aggregate industry. geophysics can be extremely cost-effective in developing resource and reserve estimates for pit and quarry operations. The survey data is processed by our geophysicists using state of the art software.

Typical applications for these services include:
* Cost-effective correlation of limestone and dolostone resources using borehole geophysics;
* Characterising sand and gravel deposits using electrical resistivity imaging (ERI) surveys;
* Mapping depth to bedrock using ERI or seismic refraction surveys to assess overburden stripping requirements for quarries; and
* Assessment of bedrock structure using ground penetrating radar (GPR).

Golder geophysics provides geophysical consulting and contracting services for engineering, environmental and mining projects around the world. Our expertise covers the full spectrum of terrestrial, marine, and borehole based geophysical surveys.
