Rockhaven Resources Ltd. Outlines Second High-Grade Au and Ag Discovery at Klaza Project, Yukon: Drilling Intersects 15.38g/t Au and 741g/t Ag (30.20g/t AuEQ) Over 1.46m at the Western Klaza Zone

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:

  • 25.3 g/t gold and 637 g/t silver (38.04 g/t gold EQ*) over 0.96 m - Hole 178
  • 20.6 g/t gold and 93.8 g/t silver (22.48 g/t gold EQ) over 1.06 m - Hole 180
  • 14.60 g/t gold and 778 g/t silver (30.16 g/t gold EQ) over 0.82 m - Hole 182
  • 30.90 g/t gold and 5.28 g/t silver (31.01 g/t gold EQ) over 0.66 m - Hole 184
  • 2.56 g/t gold and 757 g/t silver (17.70 g/t gold EQ) over 2.01 m - Hole 206
  • 7.74 g/t gold and 427 g/t silver (16.28 g/t gold EQ) over 1.27 m including 14.35 g/t gold and 1160 g/t silver (37.55 g/t gold EQ) over 0.43 m - Hole 214
  • 15.25 g/t gold and 789 g/t silver (31.03 g/t gold EQ) over 0.78 m - Hole 218
  • 15.38 g/t gold and 741 g/t silver (30.20 g/t gold EQ) over 1.46 m including 33.2 g/t gold and 1625 g/t silver (65.70 g/t gold EQ) over 0.53 m - Hole 220

"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.

+ 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.
KL-14-219 and KL-14-223 did not intersect significant mineralization.
KL-14-224 is a geotechnical hole that was extended to test the Western Klaza Zone structure. Results from this hole are pending.

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.
