Interpretation of geological data at the stage of gold ore deposit exploration

Many gold mines experience worsening of composition of mineral resources and reserves recently while developing ore fields which were earlier assumed as unprofitable due to extremely complicated geological conditions and low content of useful components [1]. Mining is often very difficult and expensive therefore. The most attractive sites of such deposits are only extracted partly, which results in accumulation of mean and low quality ore reserves. Selective mining of high-grade ore exclusively is often conditioned by backwardness of available technologies and equipment. Comprehensive extraction of ore reserves requires that the maximum possible information is obtained as early as the stage of geological exploration. Aiming to reduce operating costs, to embrace both high-grade and low-grade ore sites, to optimize drilling, to scale down sampling and its analysis amount, as well as to reliably delineate ore bodies, it is necessary to study spatial variabilities using the analytical and indirect methods. The presented material and petrography analyses accomplished by the authors enable adjustment of boundaries of ore lodes and veins using the methods of interpretation, statistics and trend-analysis. Evaluation and processing of the very conflicting empirical data on the subsoil allow following up spatial distribution patterns of useful components.

Keywords: mining, gold production, data processing, exploration drilling, sampling, trendanalysis, distribution patterns, data interpretation.
