True, but they have said many times they need $5 million not just $500k. They'd have to do private placements at a discount to market, 20-50% discount for restricted stock is quite normal.
Even at today's price that's close to 2 billion shares, discounted from today's close it could be close to 4 billion, more than doubling the outstanding.
I can pretty much guarantee you that any production for the first number of months will not provide enough profit, if there is any, to keep them going for long without raising additional cash.
