Pacific Booker Minerals Inc. Completes HPGR/SAG Mill Trade-off Study

    VANCOUVER, British Columbia, Dec. 13 /PRNewswire-FirstCall/ -- The
 Company (Amex:   PBM; CDNX: BKM.) is pleased to announce that Wardrop
 Engineering Inc. have completed a Trade-off Study to evaluate the
 application of High Pressure Grinding Rolls (HPGR) as an alternative
 technology to the conventional semi-autogenous (SAG) milling process for
 the Morrison project. The results of the Trade-off Study indicate that the
 application of HPGR, with an initial capital cost of approximately CDN $10
 million higher than a SAG milling process, would result in significant
 operating costs savings amounting to more than 23%. The reduction in power
 for the combined crushing/grinding circuits for the HPGR option is 3.67
 megawatts (MW). The resulting power savings translates into an operating
 cost savings of CDN $0.08/tonne and for consumables; the reduction was
 estimated to be CDN $0.59/tonne for a total cost saving of CDN $0.67/tonne
 over the life of the mine. For more information regarding PBM and the
