Table 15.3 - Bear Lodge Mineral Reserve Estimates
(WLRC, 2014)
Sub-grade and waste rock are estimated at nearly 133 MM tons, for an average
stripping ratio of 8.5 (tons waste per ton of mineral reserve). Total material within the
ultimate pit, including the above mineral reserves, is estimated at over 148 MM tons.
While treated as waste rock in this study, approximately 12 MM tons of inferred
mineral resources grading 2.41% TREO are estimated within the ultimate pit design
(above 1.50, 1.75 and 1.00% TREO cutoffs for BH Ox, BH OxCa and WT Ox+OxCa
ore types, respectively).
Mineral resources that are not mineral reserves do not have demonstrated economic
viability. Inferred mineral resources have a great amount of uncertainty as to their
existence and as to whether they can be mined legally or economically. There is no
certainty that the any of the estimated inferred mineral resources will be converted to
measured or indicated mineral resources.
