Rockhaven Resources Ltd. Continues to Intersect High-Grade Gold and Silver Mineralization at the Western BRX Zone, Klaza Project, Yukon
July 22, 2014 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce results for five additional drill holes from the 2014 program at its 100%-owned Klaza property located in the Dawson Range Gold Belt of southern Yukon. The 12,000 m diamond drill program is focused on delineating and expanding areas of high-grade gold and silver mineralization within multiple structural zones that have been identified on the property.
Highlights from the new drill holes testing the Western BRX Zone are as follows:
Western BRX Zone
The Western BRX Zone is the main target of the 2014 diamond drill program. It is a 750 m long, linear structure hosting high-grade gold and silver veins emplaced alongside or in close proximity to a feldspar porphyry dyke. Systematic infill and step-out diamond drilling in 2014 at the Western BRX Zone has further confirmed the continuity of the structure while delineating areas of high-grade gold and silver mineralization. Twelve of the thirteen holes reported from 2014 drilling have tested a 400 m section of this 750 m long zone. The other hole (KL-14-146) appears to have entered an offset fault that post-dates mineralization, before reaching the targeted Western BRX Zone.
Significant new results, including some from mineralized secondary structures, are shown in the table below.
+ Represents the diamond drill hole length. True widths are estimated to be approximately 80-90% of the interval.
*Gold equivalence (EQ) has been calculated using metal prices of $1300 per ounce gold and $26.00 per ounce silver, to be consistent with earlier calculations and assumes 100% recoveries of both metals.
Drilling and trenching at the road-accessible Klaza property since 2010 have identified nine main mineralized structural zones and numerous subsidiary structures within a 2,000 by 4,000 m corridor. Individually, the main zones range from 1 to 75 m in width and are continuously mineralized over strike lengths of 250 to 2,400 m. The zones have been traced over a cumulative strike length of 9,400 m and all remain open for expansion along strike and to depth.
Maps, sections and an expanded assay list which includes copper, lead and zinc values for the significant intervals can be viewed at the Company’s website at www.rockhavenresources.com. Additional results from the 2014 exploration program at Klaza will be released once assays are received, compiled and evaluated.
All analyses for rock and core samples from the 2014 program were performed by ALS Minerals with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. Core samples are 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 exceed the detection limits of the routine methods are 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 are in place regarding sample collection, chain of custody and data entry. Certified assay standards, coarse reject duplicates, field duplicates and blanks are routinely inserted into the sample stream to ensure integrity of the assay process. All of the results reported have passed the QAQC screening.
The 2014 program is 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.

Highlights from the new drill holes testing the Western BRX Zone are as follows:
- 26.80 g/t gold and 705 g/t silver (40.90 g/t gold EQ*) over 0.84 m and 29.30 g/t gold and 36.8 g/t silver (30.04 g/t gold EQ) over 1.01 m - Hole 144
- 10.79 g/t gold and 121 g/t silver (13.21 g/t gold EQ) over 2.90 m - Hole 145
- 15.95 g/t gold and 123 g/t silver (18.41 g/t gold EQ) over 1.89 m - Hole 147
