Mining professionals use ground penetrating radar for mineral exploration in igneous and metamorphic rocks, such as granitic pegmatite, to locate hydrothermal features including cavities and vugs. This 2D data set shows a large void containing emeralds in a pegmatite mine. This data was collected with a 900 MHz in contact with the rock surface.
The most commonly used first step in geophysical exploration process is the aeromagnetic survey. A magnetometer or often a series of magnetometers are attached to an aircraft in a stinger, or wingtip pods to measure the intensity of the earth's magnetic field, thereby permitting the detection of magnetic anomalies caused by the minerals that are present in the ground.

Self Potential (SP) geophysical surveys measure the potential difference between any two points on the ground produced by the small, naturally produced currents that occur beneath the Earth's surface. The SP method is passive, non-intrusive and does not require the application of an electric current.
Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface. Investigation depth ranges from 300 m below ground by recording higher frequencies down to 10,000 m or deeper with long-period soundings.

When initial survey data are correlated to known mineralization, even dead holes or drill "misses" become useful as each layer of information helps refine the picture and guides the next round of exploration. Whether the target is a base metal, precious metal, or industrial mineral, geophysics illuminates the path to success.
A geophysical survey is a method of collecting information about the physical properties of rocks and sediments. This method is also increasingly applied to mineral exploration activities. It provides a reliable result of the types of hydrocarbons and minerals present underground without tunneling ...
Oct 12, 2011· Geophysical survey methods are becoming increasingly accepted and implemented in the field of mineral exploration. These surveys provide a reasonably reliable idea of the types of minerals and hydrocarbons present below the ground without any actual digging or tunnelling.
GeoPotential was founded in 1979 as a geophysical consulting company in the oil and mineral exploration industries. Since the mid 80's we have gradually expanded into environmental and engineering geophysical consulting, primarily to environmental and engineering firms. The size of the company has fluctuated between 3 and 12 employees.
in the survey area. Geophysical methods all depend on measuring a physical property of rocks. There are only a few such properties, shown in Table 1: Table 1: Geophysical properties useful for surveys, roughly in order of increasing survey cost.

Geological and Geophysical (G&G) Surveys Why Are Geological and Geophysical (G&G) Surveys Conducted? G&G surveys are conducted to: (1) obtain data for oil and gas (O&G) exploration and production, (2) aid in siting offshore (i.e., O&G, renewable energy) structures, and (3) locate marine mineral resources. More specifically, G&G surveys are
Geophysical surveys can help identify resources without the need for sampling and are usually undertaken with minimal surface disturbance. Different geophysical surveys measure various physical properties of the Earth and have different applications and equipment. Geophysical surveys can be conducted from the air, on the ground or down drill holes.
Drone magnetometer surveys also minimize noise from boulders and operator movement which are encountered in ground surveys. Drone Magnetometer Surveys vs Airborne Surveys. Mineral exploration is a natural fit for a UAV magnetometer survey for a number of reasons.

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
