Map Screenshot_2014-08-15-08-47-01 was posted twice. I did something different this time. The red line box rectangle is to mark only where it seems to be the most important signal. Then checked for gold only signals, big or small.
Here is what happened. You see on one, 2 red boxes together with a red X where they touch, an orange circle around it. This hit wasn't hard to pinpoint.
Another map had double red hits with double gold hits above it. I put a red X between all of these. The target is large enough to cause responses all around it. I'd first check to make sure this isn't natural gold in the ground or veins.
Then a map with 2 red boxes in different places, the gold hit in another location.
