Sorry, I am very bad at typingt...
There seems to be a bit of confusion here regarding the location of some of PRB's properties in relation to NOT's discovery properties.
This is understandable given the number of maps in circulation that are not up-to-date, and the fact that NOT's discovery properties were recently acquired and do not feature of many of the maps.
However, if you go to this page on the PRB website (http://www.probemines.com/s/McFauld.asp), you will see that PRB has done a good job of ubpdating their maps to show the location of NOT"s discovery properties, the NOT discovery, and the location of their properties adjacent to these properties. Obviously it is in their best interests to do this, which is why their information is up-to-date.
Click on the map at the top of the page (Location Map) and you will get an enlarged view...
