VANCOUVER, BRITISH COLUMBIA--(July 29, 2014) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce results for twelve additional drill holes from the Western BRX Zone at its 100%-owned and road-accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. The most recent results continue to delineate areas of high-grade gold and silver mineralization within the Western BRX Zone (See News Release dated July 15th 2014 and July 22nd 2014). The current 12,000 m diamond drill program is focusing on the BRX and Klaza Zones which are two of the nine well-mineralized structural zones that have been identified on the property.
Highlights from the new drill holes testing the Western BRX Zone are as follows:
"The current drill program is proving to be highly successful and is validating that the Western BRX Zone is a significant gold-silver discovery," stated Matt Turner, CEO of Rockhaven Resources. "The new holes continue to indicate exceptional continuity and size potential and are encouraging Rockhaven to test this target further along strike and at depth."
Western BRX Zone
The Western BRX Zone is the main target of the 2014 diamond drill program. The zone consists of three linear vein structures which have been traced over a 750 m strike length and from surface to a maximum down-dip depth of 400 m. The highest grade veins are emplaced directly adjacent to or in close proximity to the hanging wall (BRXh) and footwall (BRXf) contacts of a feldspar porphyry dyke that can be traced along the length of the zone. A secondary vein (BRXb), located 20 to 70 m into the hanging wall of the dyke, is oriented slightly oblique to the main veins. This vein appears to be unaffected by cross-cut faults that off-set the main veins and may represent a later-stage mineralizing event.
A total of 23 of the 25 holes reported from 2014 drilling at the Western BRX Zone have tested a 580 m section of this 750 m long zone. The other two holes have defined a post-mineralization cross-fault that off-sets the zone.
Significant new results are shown in the table below.
|Drill Hole||Zone ID||
|+ 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-14-149 appears to have entered an offset fault that post-dates mineralization before testing the Western BRX Zone structure.|
|KL-14-159 is an exploration hole from elsewhere on the property. Results from this hole are pending.|
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.
In 2014, a total of 9,500 m of diamond drilling has been completed in 54 holes at the Klaza property. 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 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.
