Mineral Resources are reported on a 100% basis.
Under SEC Regulation S-K 1300, a Mineral resource is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that
there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining
dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely
an inventory of all mineralization drilled or sampled. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may
be materially affected by environmental, permitting, legal, marketing, or other relevant issues.
The SEC definitions for Mineral Resources in S-K 1300 were used for Mineral Resource classification which are consistent with Canadian Institute of Mining, Metallurgy and Petroleum (CIM)
Definition Standards for Mineral Resources and Mineral Reserves (CIM (2014) definitions).
The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral
Resources as an Indicated or Measured Mineral Resource. It is uncertain if further exploration will result in upgrading Inferred Mineral Resources to an Indicated or Measured Mineral
Resource category.
Specific gravity has been assumed on a dry basis.
Tonnage and contained metal have been rounded to reflect the accuracy of the estimate and numbers may not sum exactly.
Mineral Resources are reported within stope shapes using a $52/tonne NSR cut-off basis assuming processing recoveries equivalent to CLG with an Ag price of $22/oz, Zn price of $1.20/lb, Pb
price of $0.90/lb and Au price of $1,700/oz. There is a portion of the Esther deposit that is oxidized and metallurgical test work is required to define processing recoveries.
Zn and Pb, CM (Mlb) = Tonnage (Mt) * Grade (%) / 100 * 2204.6
Ag and Au, CM (Moz) = Tonnage (Mt) * Grade (g/t) / 31.1035; multiply Au CM (Moz) by 1000 to obtain Au CM (koz)
(10) The Mineral Resource estimates were prepared by Ronald Turner, MAusIMM(CP) an employee of Golder Associates who is the independent Qualified Person for these Mineral Resource
estimates.
