Why wouldn't they? They have heaps of cash and this is an infrastructure play for them as well as a gold play.
Gold price breaking out and gold m&a happening everywhere I look currently.. VWAP will not be able to maintain the 16-17 mark for long and the stock will break alot higher, in my opinion it is is NOW or NEVER for NST at this price.. or they wait 6 months until EAR are producing and pay a massive premium
