Summary

The scope of the review for this memorandum included:

  • a comprehensive review and classification of underground stoping methods which may be applicable as an alternative to block caving;
  • a review of literature to estimate an Operating Cost per ton (or per tonne) for the more feasible alternatives to block caving;
  • a review of other pertinent block caving operations world-wide;
  • a meeting with RCM personnel (Mses. Vicky Peacy and Kim Heuther, and Mr. Bill Hart) on 3/23/17 to discuss information needs to complete this assessment;
  • develop an estimate, based on limited information provided by RCM, of the total tons of potentially mineable material above a cut-off grade of 2% which lies at or above the -2,500 ft level;
  • project the tons vs cut-off grade (COG) line to other COGs to estimate the tons available if the COG were to rise due to utilizing a more expensive alternative mining method; and
  • discuss possible realistic alternative mining methods which may be utilized instead of block caving.
