Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of McEwen Mining (NYSE:MUX) jumped as much as 12% today after the company released production figures.

So what: In the second quarter, the company produced 35,955 gold equivalent ounces, 30% higher than a year earlier. Both of the company's mines are producing at solid levels, and management thinks it can reach 130,000 gold equivalent ounces this year. 

Now what: The strong performance was good, and it didn't hurt that gold itself was up 2.9% today. The low price of gold has hurt miners, so they can use any good news they can get on the pricing front. McEwen hasn't yet posted a profit and, with gold under pressure, I would take a cautious approach to this stock, because even higher production may not make up for falling prices.
