Update NI43-101 due "soon" will include asay reports for 313 holes, an additional 154 holes over the 159 holes in the Apr 2012 estimate. That's almost double. Mark's estimate of an increase of 38% could be low. However, his reporting of possible higher sp is to my liking. IMHO, don't think PRB will be acquired by some "big boy" in 2013. Also don't believe that spin-off strategies proposed by many posters make sense for 2013.
