GOLD-SILVER: PEA positive for Klaza says Rockhaven



YUKON – Rockhaven Resources of Vancouver says the preliminary economic assessment for its Klaza gold-silver project is positive. The PEA includes a pre-tax net present value (5% discount) of $150 million with a pre-tax internal rate of return of 20% . Post tax, those numbers are $86 million 14%, respectively.

The report, prepared by AMC Mining Consultants (Canada), relies on a combination of contractor open pit and owner operated underground longhole stoping. A 1,500-t/d flotation-pressure oxidation-leaching plant will be built. The cost of the project would be $262 million (including a $34 million contingency) plus sustaining capital costs of $96 million. All-in sustaining costs are estimated at US$966/oz AuEq.

The pit constrained portion of the Klaza resources is roughly 25%, and the balance is recoverable from underground. The total inferred resource is 9.42 million tonnes grading 4.48 g/t Au, 89.02 g/t Ag, 0.75% Pb and 0.95% Zn, or 5.92 g/t AuEq. The deposit contains an estimated 1.79 million gold equivalent ounces.

Rockhaven has an exploration benefits agreement with the Little Salmon Carmacks First Nation. Talks are continuing with the First Nation and the residents of the nearby town of Carmacks.
