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 70,000 m of diamond drilling, 20,000 m excavator trenching; airborne and ground magnetic, radiometric and VLF-EM surveys; and extensive soil geochemistry.
Drilling at the Klaza property has identified nine 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.
Two of the nine mineralized structures identified to date were the focus of the Klaza property’s maiden inferred mineral resource estimate that includes 7,040,000 tonnes containing 948,348 oz gold, 21,780,313 oz silver, 121,060,093 lbs lead and 144,340,881 lbs zinc at an average grade of 4.19 g/t gold, 96.23 g/t silver, 0.78% lead and 0.93% zinc using a 1.5 g/t gold cut-off (see Klaza Property Amended Technical Report dated June 19, 2015.) There are no underlying royalties or encumbrances on the claims that cover the mineral resource areas.
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.
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.
