[QUOTE="Hawkear, post: 673698, member: 4728"] You say that the signal although strong is much broader than a small gold signal. One immediately thinks of ground noise or a deep target which may also manifest as a broad signal at the surface (or side in this case). The fact that you can hear the signal from both sides of the column does not discount either possibility as the mineralised seam may run through the pillar. How would you check the difference? If it were a seam of mineralised material or perhaps a concentration of flour gold, perhaps the signal should be broad along the seam but narrower across the seam ie at 90 degrees. A single discrete gold nugget at some distance from the coil should produce the same signal width either way. Another thing that may be useful, could be to try and replicate the signal at home using different sized gold or lead targets at different distances from the detector coil. I have not used a GM but just some thoughts. I would really want to be very certain before doing any work on that pillar supporting that large mass of conglomerate. [/QUOTE]
