Assays of 31 samples of pyritic core from diamond drill holes under gossan at Wadi Wassat, Saudi Arabia, disclosed 0.02 oz/ton gold in five samples, and from
0.11 to 1.68 oz/ton silver in 23 samples: The tenors are too low to constitute ores of either metal. Further work is required to learn if the tenor in silver varies with depth below the ground surface, with geologic unit, or both. No apparent relation exists between the estimated amount of pyrite in the core and the amount of silver disclosed by the assays.
