Our exploration methods
Boulder exploration, geological mapping in the field, geophysical surveys, geochemical sampling and drilling are examples of the methods we use in exploration to find new mineral deposits.
Geophysical surveys
Investigates the bedrock’s physical properties. Surveys can be performed from the air, manually on the ground or using probes lowered into bore holes.
The method has limited or no environmental impact.
Boulder hunting
Physically searching on site for geologically interesting boulders that have been separated from the bedrock in connection with inland ice sheet movements and are now a part of a till layer. The discovery of e.g. copper or zinc indicates the possibility of deposits in nearby bedrock.
The method has limited or no environmental impact.
Bedrock mapping
Documents the geological properties of outcrops, including metallic minerals, and gathers the information in databases for interpretation and analysis.
The method has limited or no environmental impact.
Geochemical sampling
Analyses till and drill cuttings to trace mineralisations
Limited impact on the environment in the form of minor ground damage may occur.
Diamond drilling
Enables the mapping of the bedrock at depth, its geology and possible mineralisation. Core drilling can take place to depths as great as 2,000 metres.
This method has some impact on the environment as the bore hole entails an intervention in the bedrock.
