Abstract
Diamond drill hole number 1 at the Samrah ancient mine, Kingdom of Saudi Arabia penetrated a series of mineralized fractures. Lead, zinc, and silver are the principal ore metals and galena and sphalerito are the ore minerals identified to date. Throughout the core there is a somewhat better correlation of silver with zinc than with lead.
The richest interval of core is in the main vein, 51-1/2 feet of core from 430 to 482 feet, and averages nearly 20 ounces of silver to the ton. Within this interval, 15 feet of core from 444 to 459 feet averages 60 ounces of silver to the ton. The richest single sample represents the five-foot interval from 454 to 459 feet and is reported to contain nearly 140 ounces of silver to the ton. All of these intervals contain recoverable quantities of lead and zinc and some contain a small amount of gold.
