Pacific Booker Minerals Inc. Completes HPGR/SAG Mill
Trade-off Study
Vancouver BC, December 13, 2007: 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.
