what is current pe based on cashflow

Hi, would be interested if someone who owns and knows this stock could give me their DCF or even just say pe on say the current royalty on it's own (reefton)? share price seems tempting to buy, espesh with weakening AUD$ offsetting falls in gold price...and the fact that people aren't looking at it as a cash flow stock but an explorer which is wrong.

Anyone done the numbers on this one?

ok thanks.
