One of the likely reasons for recent selling The hold period on the (relatively) small February 2012 equity financing expired recently. James Mark Plaxton only subscribed for about 20 - 25% of that financing (only vaguely recalling though, off the top of my head), likely to maintain his (the company he represents) certain percentage ownership of NWM. As such, the other 75 - 80% went to others, and some of those shares were likely unloaded recently (it could even include some of the shares paid out as commissions).
From the February 2012 financing info:
``NWM Mining Corp announced the closing of a 6,175,000 common share private placement financing. Each share was issued at a price of $.08 per common share for aggregate proceeds of $494,000. Commissions amounting to $44,400 and 555,000 shares were paid to placement agents in connection with this financing. The private placement is subject to regulatory approval and the securities issued are subject to a four month plus one day hold period, ending June 8, 2012, in accordance with the policies of the TSX Venture Exchange and applicable securities laws.``
