On 17-Jan 2018, NST spent over $3M and bought 8.8M shares at about 0.35. So today, they just lost 50% of that. Does this make sense to anybody? BB doesn't bet on a loser, let alone hold 19%. The BFS figures look ok to me. Capex is low and IRR is great. In my opinion a T/O is not far... time to average down a little.
