(1)Preliminary feasibility study dated July 2017, prepared by JDS Mining Inc. for Desert Star Resources titled “Kutcho Copper Project Prefeasibility Study British Columbia.”
(2) Copper equivalent grade (CuEq%) calculated as copper equivalent recovered and based on commodity prices of $2.75/lb Cu, $1.10/lb Zn, $17.00/oz Ag and $1,250/oz Au and recoveries of 84.7% Cu, 75.7% Zn, 48.0% Ag, 41.2% Au. Actual economic parameters, including recoveries, are subject to change as additional test work and studies are completed.
(3) A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances a Measured Mineral Resource, demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.
(4) The economic analysis contained in the 2017 PFS does not include inferred resources.
