Earthcore by Scott Sigler

Deep below a desolate Utah mountain lays the largest platinum deposit ever discovered. A billion-dollar find, it waits for any company that can drill a world's record, three-mile-deep mine shaft. EarthCore is the company with the technology, the resources and the guts to go after the mother lode. Young executive Connell Kirkland is the company's driving force, pushing himself and those around him to uncover the massive treasure. But Kirkland and EarthCore are not the first to find this treasure. The mountain's history reveals two centuries of disappearances, murder, and insanity. The discovery of ancient platinum knives, razor-sharp despite lying untouched for 1,000 years, reveals evidence of an ancient culture. If the artifacts are genuine, they show a pre-historic empire that once spanned from the Southern tip of South America all the way up through the American Southwest. Wealth and fame lie under that Utah mountain, but at three miles below the surface, where the rocks are so hot they burn bare skin, something has been waiting for centuries. Waiting ... and guarding. Kirkland and EarthCore are about to find out first-hand why this treasure has never been unearthed. Technorati Profile
