Summary:A method and system for estimating density of material surrounding a borehole in mineral exploration, the method including inserting a tool into a drilling rod located within a borehole, the tool having a gamma radiation source and at least one sensor; raising the tool within the drilling rod; receiving gamma count readings at the at least one sensor; sending the gamma count readings to a computing device; and removing effects of the drilling rod from the gamma count readings at the computing device to calculate a density of material surrounding the borehole. Une méthode et un système pour estimer la densité du matériau entourant un trou de mine lors dune exploration minière. Cette méthode comprend linsertion dun outil dans une tige de forage située dans un trou de mine. Cet outil possède une source de rayonnement gamma et au moins un capteur. Il faut récupérer loutil situé dans la tige de forage, lire les données sur les rayons gamma captés par au moins un capteur et envoyer ces données à des services informatiques, soustraire leffet de la tige de forage du comptage de rayons gamma au moyen de loutil informatique afin de calculer la densité du matériau entourant un trou de mine.
