VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 12, 2015) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce initial 2015 Diamond drill results from its 100%-owned and road-accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. At present, two skid-mounted Diamond drills are working to expand the current mineral resource (see Rockhaven News Release dated January 25, 2015) and provide key geotechnical and environmental data to further advance the project. A total of 12,000 m of Diamond drilling in 45 holes have been completed thus far in 2015.
The four Diamond drill holes described in this release are from the Central Klaza Zone. They intersected high-grade gold and silver mineralization in the main zone and within subsidiary vein structures that are developed in the immediate footwall of the main structure. Mineralization in the footwall structure was not included in the current mineral resource. Highlights from the initial drill holes and an overlying excavator trench are as follows:
- 11.28 g/t gold, 75.9 g/t silver and 7.37% zinc over 3.68 m - Hole 258
- 5.99 g/t gold and 165 g/t silver over 0.96 m - Hole 259
- 5.20 g/t gold and 24.7 g/t silver over 2.08 m - Hole 261
- 36.60 g/t gold and 374 g/t silver over 2.00 m - Trench 79
"The new drill and trench results demonstrate Rockhaven's continued ability to make new discoveries of high-grade mineralization within the core of the Klaza property," stated Matt Turner, CEO of Rockhaven Resources. "Substantial progress is being made on geological and engineering fronts, which will be essential as the property moves toward development."
Significant new drill and trench results are shown in the table below.

Central Klaza Zone
The Central Klaza Zone forms the core of the Klaza Zone, a 2,400 m long mineralized complex that is one of the nine gold-silver zones identified to date on the Klaza property. Mineralization in the Central Klaza Zone consists of a laterally extensive complex of steeply dipping and anastomosing veins, breccias and sheeted veinlets emplaced within a 25 to 100 m wide structural corridor. Mineralization in the main zone and various subsidiary structures have been traced over a 800 m strike length and to a maximum depth of 325 m. The zone remains open to expansion to depth and into the footwall.
Since June 2015, a total of 12,000 m of Diamond drilling has been completed in 45 holes at the Klaza property. Drilling is expected to continue until the end of August when the focus will shift to engineering studies. Maps and sections can be viewed at the Rockhaven's website at www.rockhavenresources.com. Additional results will be released on a target by target basis once assays are received, compiled and evaluated.
All analyses for rock and core samples from the 2015 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 2015 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.
About the Klaza Project and Rockhaven
The road accessible Klaza project hosts a recently announced inferred mineral resource estimate that includes 7,040,000 tonnes containing 948,348 oz gold, 21,780,313 oz silver, 121,060,093 lbs lead and 144,340,881 lbs zinc at an average grade of 4.19 g/t gold, 96.23 g/t silver, 0.78% lead and 0.93% zinc using a 1.5 g/t gold cut-off (see Klaza Property Amended Technical Report dated June 19, 2015 which can be viewed at www.sedar.com under the Rockhaven profile or on the Rockhaven website).
