Rockhaven Resources Ltd. Announces Initial Assays from 2017 Drilling at Klaza Project, Yukon
12.09.2017 | GlobeNewswire
VANCOUVER, Sept. 12, 2017 - Rockhaven Resources Ltd. (TSX-V:RK) ("Rockhaven") is pleased to announce assay results from the first 28 holes of the 2017 diamond drill program at its 100% owned Klaza gold-silver property, located in the Dawson Range Gold Belt of southern Yukon. The field program was completed ahead of schedule with a total of 15,922 m in 96 holes.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.
Near surface assay highlights include:
7.57 g/t gold and 65.6 g/t silver over 2.90 m –Hole 366
14.14 g/t gold and 116 g/t silver over 1.93 m – Hole 365
36.90 g/t gold and 1,280 g/t silver over 0.83 m – Hole 341
1.25 g/t gold and 8.74 g/t silver over 14.04 m – Hole 360
6.57 g/t gold and 99.0 g/t silver over 2.22 m – Hole 362
12.65 g/t gold and 419 g/t silver over 1.16 m – Hole 343
14.10 g/t gold and 331 g/t silver over 1.13 m – Hole 344
4.78 g/t gold and 22.7 g/t silver over 2.96 m – Hole 346
3.79 g/t gold and 48.2 g/t silver over 3.78 m – Hole 339
19.50 g/t gold and 554 g/t silver over 0.63 m – Hole 342
3.00 g/t gold and 32.7 g/t silver over 6.98 m – Hole 356
“Enhancing the economics at Klaza is largely dependent on adding ounces amenable to open pit mining and these first holes help demonstrate the consistent nature and extent of the near surface gold mineralization within and adjacent to the Klaza and BRX zones,” stated Matt Turner, Rockhaven’s CEO. “These holes expand the area of mineralization and provide material needed to complete pre-concentration and metallurgical studies.”
The majority of the holes announced in this press release are from drilling conducted in the Central Klaza Zone, testing veins located within the zone and in its immediate footwall. All of the holes are situated within or adjacent to the proposed open pit as outlined in a March 1, 2016 Preliminary Economic Assessment (PEA) on the Klaza property. A copy of the PEA can be viewed on the Rockhaven website (www.rockhavenresources.com).
The near-surface veins within the footwall of the Central Klaza Zone were first systematically tested during a drill program conducted in summer 2016. They comprise a laterally extensive complex of moderate to steeply dipping, fracture-filled veins and sheeted veinlets and the majority of these veins are not included in the mineral resource estimate or proposed mine plan contained in the PEA. Samples collected from the drill program will be used for pre-concentration metallurgical test work that will begin in fall 2017.
Maps and sections from the 2017 exploration program can be viewed at Rockhaven’s website (www.rockhavenresources.com).
Significant new drill results from the Central Klaza, Eastern BRX and Pika zones are shown in Table I.

QAQC
All analyses for rock and core samples from the 2017 program were performed by ALS Minerals with sample preparation in North Vancouver, Whitehorse 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.
