it was set up from the tigers realm boys here in melbourne, they are the ones that did oxiana and then merged with zinifex to become Ozminerals
they purchased all these different assets through their vast fortunes from that and spun off gold, copper , coking coal and uranium companies onto many exchanges across the globe. look up tigers realm group to see their story,,. nexgen just happen to find the largest deposit of uranium on the planet and now we are going to make a mine from it... but we totally expect they will be taken out very very soon..
i am in a few of their spin offs. nut heavily accumulating the nexgen share on the TSX.
