"Silverado's twelve square mile, 100% owned Nolan Property has yielded over $15 million in gold. This was produced during past Silverado test mining activities. The area, over its pre-Silverado historical 'gold rush mining', produced 120,000 oz of gold, and generated a 136 oz gold nugget, the second largest ever found in Alaska. Silverado discovered the tenth largest gold nugget, at 41 oz."
