Klaza Project Overview

PROJECT HIGHLIGHTS

  • Pre-Tax NPV(5%) of $529 million and an IRR of 45%, and a Post-Tax NPV(5%) of $378 million and an IRR of 37%, at US$1,450/oz gold;
  • Exceptional value at $1,740 gold price: post-tax NPV(5%) of $540 million and IRR of 49%
  • 12-year mine life producing total payable metals of approximately 750,000 ounces gold and 13.8 million ounces silver;
  • Initial capital costs of $244 million, which includes $32 million in contingency costs. Life-of-mine (“LOM”) sustaining capital costs total $114 million;
  • Average LOM operating cash cost of US$613/oz AuEQ* and total all-in sustaining cost of US$875/oz AuEQ*;
  • Annual payable metal production exceeds 100,000 ounces AuEQ in years three through seven; and,
  • Only the upper portions of three out of eleven known mineralized zones are included in Mineral Resources evaluated by this PEA, and there is excellent potential for value enhancement through additional exploration.
  • 100% Owned By Rockhaven Covering 25,000 Hectares
  • Road Access To The Property And Only 50 km From Major Highway
  • Exploration Benefits Agreement Signed With Local First Nations

Klaza Project Overview - Project Map

The Klaza Property is 100% owned by Rockhaven Resources Ltd. and covers an area of 25,000 hectares, 50 km west of Carmacks. It is favourably located within the southern part of Yukon’s Dawson Range Gold Belt, an under explored area that hosts a historical gold mine, rich placer gold deposits and key infrastructure such as road access.The Klaza property is road accessible by a two-wheel drive road from the Klondike Highway. Rockhaven’s exploration to date has included over 100,000 m of diamond drilling, 24,500 m excavator trenching; airborne and ground magnetic, radiometric and VLF-EM surveys; and extensive soil geochemistry.

Drilling at the Klaza property has identified 12 main mineralized zones and numerous subsidiary structures which have a cumulative mineralized strike length greater than 10 km. The zones are hosted within a 1.8 km wide structural corridor consisting of Mid-Cretaceous granitic country rocks. Individual zones range from 1 to 75 m in width and consist of quartz-sulphide veins, breccias and fracture networks that are spatially associated with unmineralized quartz-feldspar porphyry dykes. They exhibit exceptional lateral and down-dip continuity, and all zones remain open for extension along strike and to depth.

The mineralized structural zones correlate well with intense magnetic lows and VLF-EM conductors that are often accompanied by anomalous gold, silver, lead, zinc and arsenic soil geochemical results. Follow up of some of the geophysical and soil geochemical anomalies continue to result in new discoveries.

An updated PEA was completed in July 2020 and has demonstrated the excellent economic potential of the Klaza Project.At a base case gold price of US$1,450/oz gold, the Klaza project has a Post-Tax NPV(5%) of $378 million and an IRR of 37%.At current prices (US$1,740), the project has an exceptional value of post-tax NPV(5%) of $540 million and IRR of 49%.The following tables summarize the results of the updated PEA and its sensitivities.

An updated Mineral Resource was prepared by AMC Mining Consultants (Canada) Ltd. and announced on June 21, 2018 and forms the basis of the 2020 updated PEA. Results of this Mineral Resource estimate are summarized below.

  1. CIM Definition Standards (2014) were used for reporting the Mineral Resources. Using drilling results to December 31, 2017. The Qualified Persons are Adrienne Ross, P.Geo. of AMC Mining Consultants (Canada) Ltd, and Nicholas Ingvar Kirchner, FAusIMM, MAIG. of AMC Mining Consultants Pty Ltd.
  2. Near surface Mineral Resources are constrained by an optimized pit shell at a metal prices of $1,400/oz Au, $19/oz Ag, $1.10/lb Pb, and $1.25/lb Zn.
  3. Cut-off grades applied to the pit-constrained and underground resource are 1.0 g/t and 2.3 g/t AuEQ respectively.
  4. Gold equivalent values assume $1,400/oz Au, $19/oz Ag, $1.10/lb Pb, and $1.25/lb Zn, and variable recoveries for the different metals.
  5. Numbers may not add up due to rounding. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. All metal prices are quoted in US$ at an exchange rate of $0.80 US to $1.00 Canadian.

Investors should be cautioned that the preliminary economic assessment is preliminary in nature, that it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.

Technical information in this summary has been approved by Matthew R. Dumala, P.Eng., a geological engineer with Archer Cathro and qualified person for the purpose of National Instrument 43-101.
