Abstract

The Samrah mine, near Ad Dawadimi, Kingdom of Saudi Arabia, has been explored by 18 diamond drill holes, aggregating 3,624.3 meters in length. The holes demonstrate that the Samrah vein zone follows premineral andesitic dikes. Smaller veins split away from the main Samrmh vein zone, The Samrah vein zone is known to be mineralized at the surface for at least 400 meters and to a depth of a of the least 220 meters below the surface. Within this mineralized part of the vein zone diamond drilling has indicated ore reserves of approximately 204,000 metric tons, the average value of which is estimated at $57 per ton.
