This is its investor presentation.  By my calculation, the PE ratio is under 5 (NPAT of $8.4 million, market cap of $46.6 million).  Debt is not insignificant at $24.8 million but it is mostly for working equipment.

The contracts are for long life mines, blue chip firms and all in Australia.  But don't expect anything dramatic with this kind of stock.  The share price might even fall due to market sentiment against coal stocks.  This one is actually a mining service company.  Its rigs are not used for exploration but to open up the ground for mining.
