LRL's are not supposed to detect minerals unless you have it set to do so. What can happen is in conductive ground the signal dissipates into the conductive material. Salt water is bad and the signal only travels a short distance. Graphite is one of the worst. Clay layers can cause problems, too. Wet conditions can make salty soil conductive. Some areas that have a rainy season and volcanic soil can make it unusable.

Handheld devices are not the way it should be done. You need to set the transmitter on the ground and let it run for several minutes for the line to the target to develop. Then circle the transmitter with an L-rod to find the line. Otherwise you get no discrimination.
