There is a vein of uranium ore that runs from George West Texas to almost Texarkana Texas. When determining where to place a mine, the following steps are accomplished: (1) A geologist with a geiger counter flies over the area and finds the highest radiation reading. (2) Drilling trucks are sent out and core samples are drilled to determine the highest concentration of uranium ore. These core samples are drilled in a grid pattern and every core sample is given a tracking number and logged in showing the concentration and amount of uranium present. (3) The open pit mine is then laid out according to these core samples.
