we're going mining >> 6 month price target, page-6

re: we're going mining >> 6 month price ... URA has the option to increase their shares to %75 and they will IMO

Is company tax of %35 paid on revenues? or profit at the end of the finacial year? after including all the expenses associated with production, exploration, acuestions etc. I would think that a half clever accountant could see them not paying much of that %35 tax mentioned above. or is it royalities ?
