This part of doublewides post is very good. I'm no geo but it makes sense to me. well done doublewide.

Formation of deposit...this is not a Sudbury look alike. There is no reason at this time to think the geology in this area is anything more than a typical granite-greenstone belt, similar to others found around the world. To the best of my knowledge Dr. Mungall has had a few graduate students complete studies on the Sudbury structure, as have too numerous to mention other professors from around the world. That hardly makes him an expert on Sudbury. In fact he has probably completed more work on the Ungava nickel deposits in northern Quebec. These types of deposits are probably closer analogies for deposit types. Intrusive ultramafic bodies enriched in nickel. His main point, and worth repeating here, is that the amount of sulphide found in this small intrusion is more than what should be normally expected. Therefore the geologic system must have been significant enough and long lived enough to allow lots of sulphide enriched magma/lava to flow through this area and deposit the nickel rich sulphide. There should be more around!
