Rockhaven drills 0.61 m of 182 g/t Au at Klaza

Mr. Matthew Turner reports

ROCKHAVEN INTERSECTS 182 G/T GOLD OVER 0.61 M AT KLAZA PROJECT, YUKON

Rockhaven Resources Ltd. has released assay results for an additional 21 diamond drill holes from the 2017 exploration program at its 100-per-cent-owned Klaza gold-silver property, located in the Dawson Range gold belt of southern Yukon.

A total of 15,922 metres in 96 holes were completed during the 2017 exploration program. Results from the first 28 holes were released on Sept. 12, 2017. The main objectives of the 2017 program were to: better define and expand the near-surface mineral resources through infill and stepout 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 were mostly from the Central Klaza and Eastern BRX zones.

Assay highlights from this news release include:

  • Hole 376 -- 182 grams per tonne gold and 231 grams per tonne silver over 0.61 metre and 7.00 grams per tonne gold and 7.12 grams per tonne silver over 2.92 metres;
  • Hole 370 -- 4.18 grams per tonne gold and 30.1 grams per tonne silver over 6.94 metres;
  • Hole 383 -- 13.38 grams per tonne gold and 397 grams per tonne silver over 1.05 metres;
  • Hole 372 -- 4.41 grams per tonne gold and 23.0 grams per tonne silver over 5.81 metres;
  • Hole 380 -- 4.10 grams per tonne gold and 46.3 grams per tonne silver over 4.32 metres;
  • Hole 384 -- 3.09 grams per tonne gold and 7.01 grams per tonne silver over 5.60 metres;
  • Hole 373 -- 12.09 grams per tonne gold and 43.7 grams per tonne silver over 1.20 metres;
  • Hole 368 -- 5.16 grams per tonne gold and 16.7 grams per tonne silver over 3.00 metres;
  • Hole 385 -- 12.20 grams per tonne gold and 57.5 grams per tonne silver over 1.05 metres and 12.60 grams per tonne gold and 166 grams per tonne silver over 0.90 metre;
  • Hole 378 -- 4.50 grams per tonne gold and 96.0 grams per tonne silver over 2.76 metres;
  • Hole 374 -- 3.15 grams per tonne gold and 10.1 grams per tonne silver over 4.31 metres.

"The 2017 exploration program continues to produce consistent, high-grade results from near-surface targets," stated Matt Turner, Rockhaven's chief executive officer. "We are especially excited by the results from drill hole 376, which includes the highest-grade intersection to date from the Klaza project. This is similar to intercepts that characterize the Western BRX zone. Prior to hole 376, the best drill interval from the project (66.20 grams per tonne gold and 403 grams per tonne silver over 1.00 metre) came from hole 154 within the Western BRX zone (July 29, 2014, news release)."

Current mineral resources within the Central Klaza zone relate to veins emplaced along and adjacent to moderately dipping, northwest-trending dikes. A secondary set of mineralization is developed in the footwall of the primary vein system. This footwall mineralization trends oblique to the primary trend and comprises an extensive network of narrow veins and mineralized fractures. Many of the intercepts announced to date from the 2017 program lie outside of the current mineral resource and existing mine plan, as presented in the March, 2016, preliminary economic assessment report prepared by AMC Mining Consultants (Canada) Ltd. Drilling this year has demonstrated that higher-grade and/or wider mineralized intervals exist within the Central Klaza zone, at junctions between the two mineralized trends.

Drilling within the Eastern BRX zone was designed to better delineate veins and fracture fillings that comprise the zone. Core from this year's program will be used for additional metallurgical testing, which is necessary to incorporate the Eastern BRX zone into future economic studies.

Maps and sections from the 2017 exploration program can be viewed at Rockhaven's website.

Significant new drill results from the Central Klaza (KZA), Eastern BRX (EBRX), Central BRX (CBRX), Pika, AEX, BYG and Dickson zones are shown in the attached table.

Quality assurance/quality control

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 quality assuance/quality control screening.

The 2017 program was managed by Archer Cathro & Associates (1981) Ltd. Technical information in this news release has been approved by Matthew R. Dumala, PEng, a geological engineer with Archer Cathro and qualified person for the purpose of National Instrument 43-101.
