Exactly. Paying a one-time dividend will only suck money out of the bank.
There have been a few posts that talk of rewarding long-time shareholders with a dividend. As far as I know, dividends never reward long-term holders, but rather every shareholder. Meaning, daytraders can just pop into MRZ to get a cash payout, or more likely, play the momentum of the announcement (the stock is not liquid enough to guard against overpaying for the stock in the first place). All that does is add volitility to the stock and take valuable money away from exploration.
