I saw an interesting presentation the other day. Magma Ventures have this interesting property near Thunder Bay (I am not touting the company either!). One of their slides on their web shows their version of a meandering sulphide rich and PGE rich tube that wonders across the countyside. It is a plan map, and drilling at first was difficult due to its meandering nature. Perhaps Noront has the same problem only in vertical section which will compond locating a large massive sulphide deposit. They have interesting results but they got to find the meandering channel, which will take a lot of close space drilling.
