Geochemical methods of ore and precious metal deposits prospecting and exploration

Mining geochemistry

Continuously complicating conditions of identification and evaluation of ore and precious metal deposits require constant improvement of geological exploration methods. Particularly relevant is the problem of prospecting in areas where numerous types of hypergenic anomalies are widely developed in different climatic landscapes, where the application of traditional geological and geophysical methods is not always effective.

Geochemical methods, in comparison with traditional geological and geophysical studies, make it possible to not only predict metallogenetic features of the sedimentary section on the structural-tectonic basis but also to rank the forecast sites for reserves and conduct a qualitative assessment of ores and buried precious metal placers.

The company uses highly effective geochemical methods of prospecting for ore and placer deposits of non-ferrous and precious metals. These methods are based on previously unknown patterns of migration of elements and their concentration on natural specific sorbents, which make it possible to ensure high reliability and transmission distance. Along with this, the methods used are express, economical, do not require special equipment, and are low-cost.

They include:

Bacterial-geochemical method is characterized by ultrahigh resolution (transmission distance), which allows predicting ore objects hidden or covered under allocations, as well as placers at any depths. It is also used for identification and delineation in closed landscapes of kimberlite pipes.

Mercury-salt lithogeochemical method for salt superimposed halos of highly mobile, including closed type ore elements.

The lithogeochemical method based on conducting prospecting for dispersion fluxes possesses high information capacity and reliability of the forecast.

The quartz-geochemical method is based on the features of the location of detrital fractions of vein-hydrothermal quartz in the hypergenic zone as the main mineral-forming component of gold ore formations.

The hydrogeochemical method is carried out in two options: along the river and slope waters.

The phytogeochemical method is used to prospect for noble metal deposits using plants as testing objects, which are the most widespread in natural landscapes.

The results of geochemical work allow, with a small number of appropriations, to reduce the level of risk in determining the location of ore-bearing and alluvial objects, relocation, and reduction of drilling and mining operations.
