Potential field experts
Initial Exploration Services was built on a solid foundation of gravity and magnetic surveys. Potential field surveys account for the majority of our annual projects nationally and internationally and we are widely considered world leaders in this field. With our inventory of 10 CG5s and CG6s, we are capable of conducting small micro-gravity/geotechnical projects all the way up to regional geoid projects.
We have experience in every type of climate and terrain and have developed unique field procedures to get the job done safely, efficiently and cost effectively.
Initial Exploration Services was the first gravity service provider to incorporate both UAV and GPR acquired digital elevation models to process the most rigorous terrain correction in the industry.

Ground Gravity: applications
Regional Mineral Exploration
Regional Mineral Exploration
Regional Mineral Exploration
Gravity is used for geological and structural reconnaissance to determine rock type, soil compaction, the presence of water and to create plausible deposit models: (greenstone belts, sedimentary basins, ultramafic rocks, granitic batholiths, karst, calderas, volcanic domes, structural corridors and faults).
Local Mineral Exploration
Regional Mineral Exploration
Regional Mineral Exploration
Gravity is used for geological and structural mapping to directly delineate ore-bearing structures: (skarns, horsts, grabens, brecchias, silicification and alteration or intense fracture zones).
Mine / Deposit Exploration
Regional Mineral Exploration
Mine / Deposit Exploration
Gravity is used for the direct detection of either excess of mass: (massive sulphide deposits associated with nickel, chromite ore, banded iron formations, stock works, and barite deposits) or depletion of mass: (coal, lignite, salt deposits, placer, karst and kimberlites).
Petroleum Exploration
Petroleum Reserve Exploration
Mine / Deposit Exploration
Gravity is used where seismic imaging has been challenged by complex geology, crew safety or practical inaccessibility. Gravity is used to map the subsurface structures under thick salt and in volcanic provinces where seismic methods have imaging problems.
Petroleum Reserve Exploration

Ground Magnetics: applications
Regional Mineral Exploration
Regional Mineral Exploration
Regional Mineral Exploration
Magnetics are used to understand the general structure of underlying rock by identifying faults and folds otherwise hidden beneath the surface.
Local Mineral Exploration
Regional Mineral Exploration
Regional Mineral Exploration
Magnetics are used to discover and evaluate the size and shape of ore bodies by mapping the magnetism of underlying rocks.
Mine / Deposit Exploration
Regional Mineral Exploration
Mine / Deposit Exploration
Magnetics are used to define deposits:
Iron ore, gold, copper, zinc, nickel, diamonds, chromite, manganese, asbestos.
Petroleum Exploration
Geothermal Exploration
Mine / Deposit Exploration
Magnetics are used to determine depth to basement rocks and to locate and define the extent of sedimentary basins.
Geothermal Exploration
Geothermal Exploration
Geothermal Exploration
Magnetics are used to identify demagnetised rocks produced by the heat of geothermal activity; potential epithermal gold deposits.
