Molycorp (NYSE: MCP) has seen deteriorating finances all year but the fourth quarter is when it all came to a head. Last night after the market closed the company reported a $362.4 million loss, or $2.91 per share, as it wrote off assets that aren't worth nearly what the company thought they were when the stock was a hot item.  

Despite the fact the company is now in full production, revenues are only up 1% year over year to $134.3 million, which is down 35% from a quarter ago. Molycorp also blew through $89.6 million of cash in 2012; with rare-earth mineral prices falling, that rate should increase in 2013. Hence the $414.2 million it needed to get from investors at the start of the year.

The price of common rare-earth minerals has been dropping since 2011, the year prices peaked, which is why revenue is slipping. The table below shows a few of these minerals courtesy of competitor Lynas, who is also dealing with similar challenges as Molycorp.

It's a wonder at this point that miners without production, like Rare Element Resources and Avalon Rare Metals, are still in business at all. If Molycorp can't make money now that it's in full production, then how could there be enough demand to support all of these companies?

Foolish bottom line
Fundamentals have only been getting worse for Molycorp over the past year, so unless prices improve dramatically I don't see a profit in the company's future. I'd stay away from this stock as well as Rare Element Resources and Avalon Rare Metals after this terrible fourth quarter.
