NSU employee stock options....
As of Dec 2015 there were 12,893,833 employee stock options issued ranging from $3.14 to $6.37 Canadian per share. Considering they can issue up to 10% of their outstanding stock (300 million shares) in options I believe they can issue up to another 17 million options. I went back and checked and I see that they do not issue the max but I do expect them to issue a good bit more before they prove up Timok....
