The development of geostatistics as an ore reserve estimation methodology emerged in France in early 1960 from the work of Matheron (1962) and was based on original studies by D.G. Krige functioning the optimal assigning of weights to the neighbouring sample values used in estimating the grade of blocks in South African gold mines. Geostatistics … Read more
INTRODUCTION In areas where soil cover is thin, the location and testing of bedrock mineralisation is made relatively straightforward by the examination and sampling of outcrops. However in locations of thick soil cover such testing may involve a deep sampling program by pitting, trenching, or drilling. Pits and trenches can be a quick and cheap … Read more

Lithologging of drill core of boreholes is an important stage in mineral exploration and it is done in reconnoitery, exploratory and evaluation stages of drilling to characterise the lithology. What is lithologging? Lithologging is systematic, depth wise enumeration of details of Core/Sludge samples or rock exposure in cross sections. Objective of lithologging: The basic objective … Read more
