While explaining to my sister and wife the details of the McFaulds Lake Ring of Fire, I ended up having to tell them what VMS and MMS referred to. I had to look it up and after some digging in Google, was able to find the following link, which is fairly easy for the layman to read. The articles were written in reference to Voisey's Bay, but the same holds true when referring to the ROF. Actually, the similarities are striking, might get everyone who reads it rather bullish :)

Enjoy!
