As is said, gold is where you find it, which is not always where you would like it to be. Since we want to find the rocks that are on top of the intrusives we have to be higher than they are. Since they are generally more resistant to erosion than the surrounding rocks they weather positively and create topographic highs... mountains. Thus to find what is above the intrusives, when erosion has removed the rock around them, we have to go high. In one place I have a totally unexposed large intrusive that is only indicated by an air mag anomaly and it's in relatively low country for here. That could be a totally virgin intrusive cupola; if it's mineralized it could be a monster. Pretty exciting. The high ground we're working on in the picture is formed by resistant intrusives and the hornfels shell around them. Not much intrusive is exposed compared to what is indicated by the air mag so it's a great target.... there's also a lot of gold-bearing quartz vein material to be picked up on the ground in places. We had good visible gold in core yesterday. This piece is 2mm across
