Source: Micon. GMPV (gross mineral product value) based on Cu $3.50/lb, Pb $1.00/lb, Zn $0.90/lb,
Ag $33/oz, Au $1700/oz.

*GMPV is the sum of the products of the metal prices shown, with a 65% gross recovery factor and the various block grades to produce a single Gross Metal Product Value (“GMPV”) value for each block. Micon reported the mineral resources by category following the guidelines of the JORC Code, for a range of GMPV cut-off values from $0 per tonne to $200 per tonne. This resource is shown for an $80 GMPV Cut-Off.
