Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce assay results for an additional 15 diamond drill holes from the 2017 exploration program at its 100% owned Klaza gold-silver property, located in the Dawson Range Gold Belt of southern Yukon.
Rockhaven Resources Ltd. (TSXV:RK) (“Rockhaven”) is pleased to announce assay results for an additional 15 diamond drill holes from the 2017 exploration program at its 100% owned Klaza gold-silver property, located in the Dawson Range Gold Belt of southern Yukon.
A total of 15,922 m in 96 holes were completed during the 2017 exploration program. Results from the first 56 holes were released on September 12, September 26 and October 16, 2017. The main objectives of the 2017 program were to: better define and expand the near-surface mineral resources through infill and step-out drilling; explore for new gold zones through drilling, trenching and geophysics; and, continue to advance the metallurgical and engineering facets of the Klaza project. Holes in this release are from the Central Klaza, Western Klaza and BYG zones.
Assay highlights from this news release include:
- 10.94 g/t gold and 81.7 g/t silver over 3.74 m; plus
2.17 g/t gold and 76.3 g/t silver over 7.09 m – Hole 388
- 8.54 g/t gold and 674 g/t silver over 2.26 m – Hole 412
- 21.13 g/t gold and 116 g/t silver over 1.36 m – Hole 392
- 6.18 g/t gold and 441 g/t silver over 1.01 m – Hole 414
- 8.91 g/t gold and 452 g/t silver over 2.69 m – Hole 419
- 6.84 g/t gold and 44.5 g/t silver over 3.69 m – Hole 389
- 1.20 g/t gold and 22.1 g/t silver over 9.52 m – Hole 427
“Drilling in 2017 has successfully expanded the area of mineralization and further confirmed the exceptional continuity of high-grade gold and silver veins within the Klaza Zone,” stated Matt Turner, Rockhaven’s CEO. “We are currently revising the geological model for this zone and anticipate an updated resource estimate in early 2018.”
Central and Western Klaza Zones
The Klaza Zone is one of eleven main vein systems identified to date in the core of the Klaza property. The Central and Western parts of the zone and adjacent subsidiary structures have been traced over a combined 1,400 m strike length and to a maximum depth of 325 m. A total of 10,300 m have been completed in 2016 and 2017 on the Klaza Zone subsequent to a resource estimate that was announced in December 2015 (See January 22, 2016 Klaza Property Technical Report on the Rockhaven website (www.rockhavenresources.com). Maps and sections highlighting results from the 2016 and 2017 exploration programs can be viewed on Rockhaven’s website.
The Central Klaza Zone is a laterally extensive complex of steeply dipping veins, breccias and sheeted veinlets emplaced within a 25 to 100 m wide structural corridor. It currently hosts an inferred mineral resource of 3,794,000 tonnes containing 470,000 oz gold, 6,796,000 oz silver, 60.2 million lbs lead and 88.3 million lbs zinc at an average grade of 3.85 g/t gold, 56.0 g/t silver, 0.72% lead and 1.06% zinc.
The Western Klaza Zone consists of a single discrete vein and currently hosts an inferred mineral resource estimate of 542,000 tonnes containing 98,000 oz gold, 3,455,000 oz silver, 7.7 million lbs lead and 10.6 million lbs zinc at an average grade of 5.62 g/t gold, 198.0 g/t silver, 0.64% lead and 0.88% zinc.
Significant new drill results from the Central Klaza (KZA), Western Klaza (WKZA) and Western BYG (WBYG) zones are shown in Table I.

All analyses for rock and core samples from the 2017 program were performed by ALS Minerals with sample preparation in North Vancouver, Whitehorse, Yellowknife or Thunder Bay and assays and geochemical analyses in North Vancouver. Core samples were routinely analyzed for gold by fire assay followed by atomic absorption (Au-AA24) and 48 other elements by inductively coupled plasma-mass spectrometry (ME-MS61). Samples that exceeded the detection limits of the routine methods were assayed for silver, copper, lead and zinc by inductively coupled plasma-atomic emission spectroscopy (Ag/Cu/Pb/Zn – OG62) and gold by gravimetric analysis (Au-GRA22). Rigorous procedures were in place regarding sample collection, chain of custody and data entry. Certified assay standards, coarse reject duplicates, field duplicates and blanks were routinely inserted into the sample stream to ensure integrity of the assay process. All of the results reported have passed the QAQC screening.
The 2017 program was managed by Archer, Cathro & Associates (1981) Limited (Archer Cathro). Technical information in this news release 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.
