$PGLC / $T.PGLC The mineral resources at Relief Canyon were modeled and estimated by evaluating the drill data statistically, utilizing the geologic interpretations provided by Pershing Gold to interpret mineral domains on cross sections spaced at 50-foot intervals, rectifying the mineral-domain interpretations on long sections spaced at 10-foot intervals, analyzing the modeled mineralization geostatistically to establish estimation parameters, and estimating grades into a three-dimensional block model.
