A mineral exploration is conducted in several stages, and the prospecting stage is arguably one of the most important. Mineral prospecting can be done in various different ways and geophysical surveys are enabling mining companies to acquire highly accurate results with regards to the mineral concentrations in the Earth’s crust. There are two specific types … Read more

Mining companies in the prospecting stage source out airborne geophysical companies that specialize in conducting highly precise surveys and employ reliable data acquisition services, as well as precise interpretation capabilities. The success of a geophysical survey is dependent not only upon the survey itself, but the ability to interpret the data obtained accurately and apply … Read more
Airborne geophysical data can be used indirectly to map some geological features in detail, including contacts, faults, shear zones, folds, alteration zones and other structures. To obtain this data, survey areas are systematically traversed by fixed wing or rotary wing aircraft carrying geophysical equipment along parallel flight lines. The traverse lines are oriented to intersect … Read more
There are a variety of geophysical survey methods that are used both in mineral prospecting or regional mapping. Using either ground or airborne techniques, geophysical companies employ the use of magnetic, radiometric and electromagnetic equipment to detect concentrations of minerals in the Earth’s crust. Magnetic Surveys: The most commonly used geophysical survey method is the … Read more
The Demand for Airborne Geophysical Surveys Greater global demand for minerals is leading to an increased demand for mineral exploration and in turn geophysical surveying. Airborne geophysical surveying, in particular magnetics and radiometrics, have become the leading technique to initiate the mineral exploration process, by acquiring data from the air. This has proved to be … Read more
Geophysical companies conduct efficient geophysical explorations for governments, individuals, mapping professionals, mining companies and others who are in the field of geophysics and who depend upon geoscientific data. The exploration of geophysics involves acquiring data from a specific terrain in terms of the mineral qualities present in the Earth’s crust. Data that can be uncovered … Read more
Geophysical surveying is a technique of the mining industry which uses a specialized instruments to measure the physical properties of rocks and soil in the surface and subsurface. The goal of geophysical surveying is to detect and/or predict the presence and position of elements and minerals, ground water, oil and gas and other components of … Read more
Radiometric Surveys detect and map gamma rays, and can be performed on the ground, in the air, or in a borehole. Airborne gamma-ray spectrometry or radiometric surveying for mineral exploration measures the gamma-rays that are emitted from naturally occurring radioactive isotopes that are found in rocks and soils near the surface. The most abundant of these … Read more
Geophysical Survey Increases Geophysical survey companies are experiencing significant growth due to increases in the number of mineral and oil exploration projects worldwide. Declines in reserves are directly tied to an increase in funding for exploration activities. Geophysical surveys are an essential part of these exploration processes and are imperative to locating mineral or hydrocarbon … Read more
A Growing Industry The practice of geophysical surveying is growing in popularity and acceptance due to breakthroughs in the technology. Geophysical surveys are important because they provide the ability to accurately map a survey area rapidly and economically. There are many innovative and exciting advances in the industry of geophysical surveys that will alter the … Read more
