NEW YORK, Aug. 3 (UPI) -- Results of a U.S. Treasury operation to audit about $21 billion in gold bars stashed in a vault at the New York Federal Reserve are expected by year's end.
Some 530,000 gold bars are in a Manhattan vault five stories underground protected by tons of steel, concrete and a 90-ton door. The audit -- which involves weighing 350 bars on an electronic scale and drilling into them to assay the purity of the granules -- began in January, the Los Angeles Times reported.
