With its subsoil rich in raw materials and minerals, Kazakhstan represents a remarkable potential for mining. Second-largest mining market in Central Asia, behind only Russia, Kazakhstan is the world's largest producer of uranium and contains the world's fifth-largest reserves of zinc. The country also holds large reserves of coal, copper, nickel, gold, silver and iron. It is not ...

Warm-up As it does every year, the Quebec Mineral Exploration Association (QMEA) organized an opening cocktail party before the start of the first day of the Xplor convention. However, it was something new for the group of participants, exhibitors and speakers to assemble at Pub Explo in Place Bonaventure to raise a glass. We had sent a few rather limited number of ...

The main goal of electromagnetic geophysical prospecting in the mining industry, which is based on variations in relative subsurface conductivity, is to detect deposits that conduct electricity. These formations are detected using the principle of induction, as they would be by a current transformer.   The usual process is to put an transmitter on the surface. It produces ...

Induced Polarization (IP) is used to measure the chargeability of the subsurface. The electrochemical effect, or IP Effect, can be influenced by many factors; grain size, surface area, types of minerals present (metallics vs. silicates vs. clays), type and mobility of ions within the pore fluid. Disseminated mineral grains, for example, have a larger overall surface area providing a ...

Aeromagnetic geophysical surveys consist of measuring the intensity of the geomagnetic field in order to detect local magnetic variations from the rocks. The resulting aeromagnetic data is generally used to support the mapping of geological formations and accidents that have effects on these in order to directly detect any concentrations of magnetic minerals.   The ...
