Indicators and Quartz reefs

I actually found a rock that signalled off on my 5000 earlier this year while out detecting with a mate and thought nothing of it first up as it was a screaming signal. I dug down no more than about 5 inches and out popped the rock being the target. i looked at it and for the life of me couldnt see anything on this rock that would have made the 5000 scream. I then broke open the rock (Was a slate/Quartz rock) and there it was. A band of gold going right round the rock. Now at closer inspection after washing it with some water i could see one edge of the rock was slate and right next to that was a thin line which looked like a bit of pencil lead and then the gold band was next that and the quartz rock on the other side of the band of gold. I took this piece to a very knowledgable person regaurding gold and the first thing he said to me was the pencil lead coloured line was the indicator line. I managed to dolly up some of the rock and have found about 6 grams of gold so far with over half to be dollyed up still. I do still have a piece that shows this line very well and if i can manage a picture i will be more than happy to post it up for all to see.

That would be great, as the say a picture paints a thousand words, I do love a picture of a gold nugget or whatever form it's in but Geology can be the key,this kind of hands on in your face knowledge could be the most valuable of the two.
