The photograph on the left shows fresh core in a core trough being described in the field prior to splitting. Coring is an essential step in evaluating a uranium deposit. Coring provides valuable radiological data on the state of the deposit's radiometric equilibrium. It also provides information on the host formation's hydrological characteristics in the form of porosity and permeability data. Core samples can also be tested metallurgically to determine amenability to milling. Without good core data, accurate ore reserve estimates cannot be made since the state of the deposit's radiometric equilibrium would not be accurately known.
The photograph on the right shows a geologist examining a three dimensional model of a uranium deposit developed from drilling data. The vertical and near vertical rods represent drill holes. Some of the holes were not precisely vertical and are represented as such in the model. The flat suspended sheets of plexiglass represent uranium mineralization. The gently inclined blue rod represents a proposed decline to be driven into the deposit in order to mine it.
