What is the Best Method of Geophysical Exploration in North America?

The Need for Cost-Effective Geophysical Exploration

Geophysical exploration in North America is is an important part of the mineral prospecting process, and is thus an extremely important methodology for Junior mining and mineral exploration companies. Geophysical exploration is essential to identify and locate different mineral commodities in a specific area. Governments also use geophysical mapping to identify anomalies, which are often indicative of the presence of valuable minerals and even petroleum.
Junior mining and mineral exploration companies operate on budgets in order to maximize the returns when a large deposit of a valuable mineral is found. This means finding the most cost-effective methods of geophysical exploration possible.

Airborne Geophysical Surveys

Airborne geophysical surveys can be coordinated and executed to quickly and effectively determine the geological makeup of a large area by measuring the following geophysical characteristics  of the subsurface:
  • Magnetics
  • Radiometrics
  • Gravity
  • Electromagnetics
Airborne exploration offers the advantage of being able to efficiently survey remote and challenging terrain.  Ground-based exploration methods are simply unable to compete economically with airborne survey methods in terms of the large area that can be covered and the time required necessary to acquire geophysical data.
Junior Mining and mineral exploration companies typically survey large areas using a variety of geophysical methodologies before a valuable deposit is accurately identified, modelled and assessed.  Airborne geophysical exploration surveys provide the most cost-effective method to survey large and remote areas and increase the chances of efficiently sourcing geophysical targets.
