RE:k92 expansion versus T.TRXTRX is nothing like K92. It has lost 60% share price in the past 3 years, is down a bunch this year, has insignificant Market Cap, and double or triple of not much is still not much production wise. And after that it seems they need to find something - not always a given. And according to Yahoo they will run out of cash in a year - so then more dilution?
But for sure sometimes these tiny companies get lucky.
