*CuEq = ((Cu%) x $Cu x 22.0462) + (Au(g/t) x AuR/CuR x $Au x 0.032151) + (Ag(g/t) x AgR/CuR x $Ag x 0.032151)) / ($Cu x 22.0462).
Commodity prices: $Cu = US$4.60/lb, $Au = US$2,600/oz., and Ag = US$30.00/oz.
There has been no metallurgical recovery testing on Kliyul mineralization.
The Company estimates copper recoveries (CuR) of 80%, gold recoveries (AuR) of 60%, and silver recoveries (AgR) of 60%
Factors: 22.0462 = Cu% to lbs per tonne, 0.032151 = Au g/t to troy oz per tonne, and 0.032151 = Ag g/t to troy oz per tonne.
