At first glance, Great Basin Gold may look to be worthwhile. With just a minimal amount of digging, pun intended, this mining stock shows its true colors. Great Basin has been able to generate revenue growth over the past twelve months at a nice rate of 49.5%. Compare this to competitor Newmont Mining’s (NEM) growth rate of just 5.7%. Great Basin’s gross margin of 37.97% is a little light compared to some of the bigger plays in the sector, such as Newmont’s gross margin of 62.47%.

The flashing warning sign, however, is the company’s operating margin of negative 8.85%. Newmont and Barrick Gold both have operating margins over 40%. Great Basin should be considered a sell, which is somewhat reflected in its current share price.
