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.
