basic valuation

Just did some reading on Whitehaven last night and have not gone into this at depth by any standard re revenues/costs/depreciation etc etc but I look at this on a very very basic valuation:

Whitehaven is doing approx 5mtpa and has a market cap of just over $3.1b.

CCC is looking at 2mtpa rising to 10mtpa by 2015. If these were comparable companies which at the moment they are not but at 40% volume to WHC rising to 200% volume of WHC would this not put the market cap over time on CCC at somewhere between $1.2B (40%) and $6.2B (200%)

Or in other words between 6x and 31x current market cap or a share price of between $0.45 and $2.38.

I know this is just pie in the sky stuff at the moment but for mine I dont think you can go wrong if you are in the for the next 4 - 5 years at current prices.

Cheers
