30 cents is sustainable .I believe NB will run higher based on more eyes and of course more news this year.That is short term.The Long term,A geologist I know(Uncle)went over the deposit figures,price of niobium,tonnage, shares outstanding in a year.Est 130 mill out at that time.NB is worth at least 2$ to 3$,and that is confirmed with a couple of brokers that did the math as well.I have been here for the long haul and will continue to hold until a buyout.Also would expect news before or during the upcoming European dog and pony show.
