Klaza Project Overview - Project Map

The Klaza Property is 100% owned by Rockhaven Resources Ltd. and covers an area of 25,000 hectares. 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 located 50 km west of Carmacks, Yukon and is road accessible by a two-wheel drive road from the Klondike Highway. Rockhaven’s exploration to date has included over 94,400 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 11 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 Mineral Resource was prepared by AMC Mining Consultants (Canada) Ltd. and announced on June 21, 2018. This new estimate comprises an Indicated and Inferred Mineral Resource. The Indicated Mineral Resource that includes 4,457,000 tonnes grading 4.8 g/t gold, 98 g/t silver, 0.7% lead and 0.9% zinc, and contains 686,000 oz gold, 14,071,000 oz silver, 73,268,000 lbs lead and 92,107,000 lbs zinc. The Indicated Mineral Resource has a gold equivalent metal content of 907,000 oz at a gold equivalent grade of 6.3 g/t. The Inferred Mineral Resource includes 5,714,000 tonnes grading 2.8 g/t gold, 76 g/t silver, 0.6% lead and 0.7% zinc, and contains 507,000 oz gold, 13,901,000 oz silver, 77,544,000 lbs lead and 89,176,000 lbs zinc. The Inferred Mineral Resource has a gold equivalent metal content of 725,000 oz at a gold equivalent grade of 3.9 g/t. 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.

Metallurgical results have been highly encouraging. Locked cycle flotation testwork, followed by pressure oxidation and carbon-in-leach cyanidation of a gold-bearing sulphide concentrate, on a project-wide composite, yielded overall recoveries of 95.0% gold, 90.8% silver, 91.2% zinc, and 84.6% lead to potentially saleable products. Additionally, recently completed pre-concentration studies from the Western BRX and Central Klaza zones were positive and demonstrate the potential to increase head-grade to the mill and reduce mill and circuit sizes of an envisioned mining operation at Klaza.

The 2018 program is managed by Archer, Cathro & Associates (1981) Limited (Archer Cathro). 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.
