VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 17, 2014) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce results for 22 diamond drill holes from the Western Klaza Zone at its 100%-owned and road-accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. The Western Klaza Zone represents a second high-grade discovery that is situated 1000 m northeast of the Western BRX Zone, the primary target of the 2014 drilling program where numerous high-grade gold and silver intercepts have been reported (see Rockhaven News Releases dated July 15, July 22 and July 29, 2014). Trenching and drilling on the Western Klaza Zone have successfully delineated areas of high-grade gold and silver mineralization over a 500 m strike length and from surface to a maximum depth of 250 m.
Highlights from recent drill holes testing the Western Klaza Zone are as follows:
"The numerous high-grade gold and silver intercepts at the Western Klaza Zone confirm the significant potential for new discoveries at our Klaza project," stated Matt Turner, CEO of Rockhaven Resources. "The strong and increasing gold grades in the deeper holes provide good encouragement to continue testing further to depth in future drill programs."
Western Klaza Zone
The Western Klaza Zone is a linear vein that was extended both along strike and to depth during the 2014 drill program. The zone has now been traced over a 500 m strike length and from surface to a maximum down-dip depth of 250 m. It lies within the same fault panel as the gold-rich veins of the Western BRX Zone, with both zones bounded by the same pair of northeasterly trending cross-faults.
The Western Klaza and Western BRX Zones share many similarities, but mineralogy and geochemistry suggest the Western Klaza Zone was formed in a more distal or higher level part of the hydrothermal system. Gold to silver ratios are increasing at depth in the Western Klaza Zone, and the veins appear to be wider and more distinct than they are near surface.
Significant results from the announced holes that tested the Western Klaza Zone and mineralized secondary structures are shown in the table below. Maps, sections and an expanded assay list, which includes drill results from previous years and includes copper, lead and zinc values, can be viewed at the Company's website at www.rockhavenresources.com.

2014 Exploration Program
The 2014 field program is now complete with over 19,000 m drilled in 104 holes. Drilling focused on delineating areas of high-grade gold and silver mineralization in the BRX and Klaza Zones. Condemnation and geotechnical drilling was also completed in strategic areas to aid in advanced permitting of the Klaza project. Gaps in the numeric sequence of the released holes result because drills were operating in more than one target simultaneously. Assay results from the remaining 57 diamond drill holes will be released on a target by target basis once assays from each target have been received, compiled and evaluated. A summary of the 2014 diamond drill program is shown in the following table.

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 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.
