Rockhaven Drills 5.78 g/t Gold and 111 g/t Silver (8.00 g/t Gold Eq) Over 15.62 m at the BRX Zone, Klaza Property, Yukon


VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 2, 2012) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce results from eight additional diamond drill holes at its 100%-owned Klaza gold-silver property located in the Dawson Gold Belt of southern Yukon. Diamond drill assay highlights from the BRX Zone and adjacent hanging wall AEX Zone are as follows:

  • DDH 88 - 4.64 g/t gold and 181 g/t silver (8.26 g/t gold EQ) over 2.58 m
  • DDH 91 - 17.65 g/t gold and 119 g/t silver (20.03 g/t gold EQ) over 1.05 m
  • DDH 96 - 5.78 g/t gold and 111 g/t silver (8.00 g/t gold EQ) over 15.62 m
  • DDH 97 - 13.05 g/t gold and 17.65 g/t silver (13.40 g/t gold EQ) over 1.31 m

The Klaza property hosts seven known structural zones with a cumulative mineralized strike length of 6.1 km. The BRX Zone discovery is a mineralized linear structure that demonstrates exceptional lateral continuity. Systematic diamond drilling has tested the BRX Zone over a strike length of 2.4 km and to a maximum down-dip depth of 400 m. The zone is open for extension in all directions.

Rockhaven has drilled 35 diamond drill holes into the BRX Zone with most holes spaced approximately 200 m apart. DDH-12-96 cut the zone 300 m down-dip of surface and averaged 5.78 g/t gold and 111 g/t silver (8.00 g/t gold EQ) over 15.62 m. This hole is the most significant intercept returned thus far from the BRX Zone and is located at the open-ended western margin of the zone. Previously announced highlights from the western part of the BRX Zone include DDH-11-37 which returned 5.43 g/t gold and 50 g/t silver (6.43 g/t gold EQ) over 14.80 m and DDH-11-39 which returned 23.50 g/t gold and 239 g/t silver (28.28 g/t gold EQ) over 1.65 m (see Rockhaven news release dated November 2, 2011).

The 2012 exploration program at the Klaza property included a total of 22,206 m of drilling in 73 diamond drill holes. Results from 18 of the 2012 holes were previously reported (see Rockhaven news release dated August 23, 2012).

The most significant assay results from the latest eight holes that tested the BRX Zone are shown in the table below. Additional results also include intercepts from the AEX Zone, which is a mineralized structure that is developed in the immediate hanging wall of the BRX Zone. Maps showing drill hole locations and cross sections can be viewed on Rockhaven's website at www.rockhavenresources.com. Assay results from the remaining 48 holes will be released on a target by target basis once assays are received, compiled and evaluated.

The Klaza property hosts seven sub-parallel, 1 to 75 m wide, structural zones of gold-silver mineralization that have been traced over strike lengths of 240 to 2,100 m. All zones consist of quartz-sulphide veins, breccias and fracture networks, which are spatially associated with quartz-feldspar porphyry dykes that intrude granitic country rocks. The zones exhibit exceptional lateral continuity and based on geophysical and geochemical evidence, they collectively form a 1.5 km wide by 8 km long northwesterly-trending structural corridor.

The Klaza property is located 50 km west of Carmacks, Yukon. The property is road accessible by a two-wheel drive road from the Klondike Highway. The property is favourably situated within the Mt. Nansen gold camp, a district that hosts an extensive system of gold-silver veins and active placer gold mining. Systematic excavator trenching and widely-spaced drilling have only been done in approximately 20% of the 66 km2 property. Untested soil geochemical anomalies and geophysical targets suggest there is good potential for additional discoveries on the property.

Core samples from the Klaza property are being processed in 36 sample batches with each batch including two assay standards, two blank samples, and two duplicate samples. Trench samples from the property are also processed in 36 sample batches with each batch including one assay standard and one blank sample. Analytical work is being done by ALS Minerals with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. All samples are routinely analyzed for gold by fire assay followed by atomic absorption (Au-AA24) and 48 other elements by four acid digestion (ME-MS61). All overlimit values are determined for gold by fire assay and gravimetric finish (Au-GRA22) and for silver using Ag-OG46. All gold and silver grades reported in this release were calculated from the assay results. All standard, blank and duplicate samples passed QAQC reviews. Individual check assaying of core samples from the Klaza property is being done at ACME Labs in Vancouver.

The 2012 program is being conducted by Archer, Cathro & Associates (1981) Limited. Technical information in this news release has been reviewed by Heather Burrell (née Smith), B.Sc., P.Geo., a qualified person for the purpose of National Instrument 43-101.
