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

VANCOUVER, British Columbia, Dec. 13 /PRNewswire-FirstCall/ -- The Company 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.
