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: Great Basin Gold (AMEX: GBG) shares jumped 10% today after the company released trial mining results from a Nevada project.

So what: A few months of stock momentum has turned into a bonanza as the Blanket Zone above the Main Clementine vein No. 18 has yielded average fully diluted value in the muck samples of 22.3 oz/ton gold and 23.4 oz/ton silver. The company released these results because locals around the mine were aware of the results.

Now what: Great Basin is currently drilling to determine the full extent of mineralization in the Blanket Zone, but initial results are positive. These results could provide a further catalyst as more mining data become available and investors get a chance to digest the news. I'm buying this move because not only are the Blanket Zone results a positive, gold prices seem to be on an endless run upward that this Fool just can't bet against.
