Dividend Policy, page-21

PLS ruled out dividends until they were paying tax, so they could be fully franked, thus giving shareholders some tax relief.

Leo probably won't pat tax in Australia - paying the 30% corporate rate in Mali, hence no franking credits.

Also in Mali there is a 10% withholding tax for money taken out of the country.

For the above reasons I can't see them paying any dividends any time soon, but would reinvest profits.
If anything possibly a share buyback similar to what Qantas did/does when it has no franking credits.
