Well I justs had a look at the newly posted presentation - not too bad, ( no new news tho ).
Perhaps that large volume buy (200k) you mentioned is a new investo & not familiar with NI ??
This stock need new investors badly, ....I also read the up-dated filings on Sedar, a little dry but worth the read I think.
.....I just want to see things (like all of us here) keep moving forward.
