Well Boot, one thing I can say is that there are Placer Deposits in the area as the largest Gold Nuggets ever found in Canada came from this exact area. One measuring about 54 ounces and another at 46 ounces and I think there is another in the 40's
This location is along a major fault line and so plate tectonics would definitely be in the cards and my guess is we are looking at a lode gold type deposit. However I think our veins are rather large, which plays into the hydaulic fracturing theory, which in turn plays into the theory that the deposit was fed from way down deep into the Earth.
I'm no geo, so what the heck do I know?
