From the past to the present, mining exploration and prospecting principles have not changed greatly, except in the diversity of minerals that are now being prospected for due to global expansions and the integration of the world´s mineral industry. Modern living standards and the need for global power have driven the industry to grow exponentially and into regions of the world that have not been explored before. The use of new sophisticated technology has enabled these areas to be explored more effectively and productively.
The Geophysical method is used for finding answers to the geometry of subsurface geologic relations that cause geophysical anomalies, environmental geophysical problems and detecting materials at deeper levels. Techniques as gamma-ray spectrometry and remote sensing are used with in this method to find materials closer to the surface. Various techniques are used for the differing materials being explored. Airborne applications can be used also for aerial mapping and surveys within the geophysical method. Thermal and some electrical methods are used to find relatively shallow materials but can also help in finding materials at a deeper level.
Magnetic technique is used for explorations to find iron ore deposits and are useful in working out what type of minerals are within the exploration area. It uses small variations in magnetic mineralogy among rocks. Magnetometers are used with this method to help with the needed results. It is mainly used for surface or just below the surface of the earth exploration.
Gamma Ray technique is used for the exploration of potassium and uranium as it can provide direct detection results. Spectrometers are used in this method as they can provide quantity and geo-environmental information. This method is used for exploration in the upper 50cm of the earth.
Electromagnetic technique measures the magnetic fields of the measurable currents of the earth. It is used for finding minerals of the sulphide family. Airborne applications are useful for this type of exploration as it is able to screen and map large areas for materials and discern the structural features of the minerals to be mined.
There are many other techniques available which can be used in the exploration for minerals and oil and the sophisticated technology that can now be used, improves on all these methods. It makes them more effective and the results they give easier to come by and more reliable.
Chopper Worx gives support to this exploration area of mining with their helicopters, providing platforms for the equipment needed to execute these various techniques of exploration. Other areas of the mining industry they can support are:
- with the long line drill moves,
- equipment relocation,
- all kinds of material sampling
- site clearances.
Providing airborne solutions to problems of varying kinds for many industries or even of personal nature is their expertise accomplishing the required result quickly and efficiently.
