Here's an excerpt from the link below. This blogger seems to have a good handle on the metcoal space.

How you can outperform my 40% gain
Because the noteworthy 70% premium offered for Grande Cache's shares would appear to make competing bids unlikely, the window of opportunity has probably been slammed shut with respect to that one met coal play. But I encourage Fools to carefully scour the sector for some stocks that could yet yield a similar or even greater return over a relatively brief span. By far my favorite remaining prospect within the sector holds a majority interest in a well-studied property within that same Peace River Coalfield in British Columbia that has clearly garnered the attention of some major operators. Because that stock has dipped deep into micro-cap territory, I will refrain from identifying the company by name, but I am confident that Fools will discover the stock in the course of their own due diligence.
My second-favorite met coal play, meanwhile, is Cline Mining. This budding new producer is busily ramping up production at the New Elk coal mine in Colorado, with a view toward reaching 3 million tons by 2013. In fact, Cline's 2012 production target of 2.75 million tons would place it ahead of Grande Cache's anticipated output of 2.2 million tons for its current 2012 fiscal year! What's more, Cline's measured and indicated resource of 388.5 million tons at New Elk easily exceeds Grande Cache's corresponding cache of 300.8 million tons (measured and indicated resource). Although variations in the precise characteristics of coal products can render direct comparisons of the sort rather problematic, I can't help but to discern compelling value in the notion that Cline's stock would need to advance by more than 200% just to reach the per-ton valuation implied in the recent bid for Grande Cache. When you toss in the $40 million in cash Cline just acquired by monetizing its Lossan deposit, the prospect turns sweeter still. Investors in the U.S. will find Cline Mining trading on the Pink Sheets under the symbol CLNMF.PK, and I strongly recommend a closer look.
