Undervalued gold mining - Calidus Australia vs Tucano Brazil

Considering a 90koz p.a. average in their feasibility study I think Calidus is way undervalued, especially with these gold prices. It's valued at less than a year's worth of projected free cash flow at these prices so think has a lot of room to revalue.
Another stock i'm excited about is Tucano Gold (ex Beadell Resources). They've taken control over the whole operation with the 10k tonne per day mill and plan to go underground next year, although OP production starting next month. Not IPO'ing until later in the year but very undervalued right now. This is the latest TG update I received http://eepurl.com/iPCRhE
