Rockhaven Resources Ltd. Announces Significant Expansion of the Klaza Zone Gold-Silver Discovery

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 30, 2012) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce the final 2011 diamond drill results from the Klaza zone gold-silver discovery at its wholly-owned, road accessible Klaza property located in the Dawson Gold Belt of southern Yukon. Highlights are as follows:

• Significant expansion of the Klaza zone with the drill indicated strike length increased to 850 m, remaining open to expansion in all directions;
  
• Mineralization in excess of 1.0 grams gold equivalent/tonne over significant widths (3.04 to 36.50 m) intersected in 36 of 40 diamond drill holes completed in 2010 and 2011;
  
• Hole KL-11-56 cut 12.51 m averaging 5.03 g/t gold and 14 g/t silver; and,
  
• Klaza zone confirmed to have both bulk tonnage and high-grade structural gold-silver mineralization similar to the adjacent, newly expanded BYG and BRX zones.

The Klaza zone is the most northerly of four parallel gold-silver bearing structural zones identified on the Klaza property. In 2011, it was tested by 10,335 m of diamond drilling in 37 holes. Drill holes that tested the Klaza zone are located approximately 50 m apart. Most are on section lines that comprise 3 to 4 holes that tested to a maximum depth of 250 m down-dip of the surface discovery.

The 2011 diamond drilling intersected significant mineralization along an 850 m strike length within the Klaza zone. The zone remains open for expansion along strike in both directions and at depth. Mineralization exhibits exceptional continuity with 36 of 40 diamond drill holes testing the Klaza zone in 2010 and 2011 intersected at least 1.0 gram gold equivalent/tonne over widths ranging between 3.04 and 36.50 m (average 13.04 m).

Mineralization within the central and western portion of the Klaza zone is hosted within a laterally extensive complex of steeply dipping veins, breccias and sheeted veinlets that are associated with a swarm of quartz-feldspar porphyry dykes. The eastern portion of the zone breaks into two sub-parallel bands. The best mineralization in these bands lies in the main zone which is on the hanging wall side of the dyke swarm.

The BRX zone is the most southerly of the known mineralized zones on the Klaza property. It is a linear gold-silver discovery that parallels the Klaza zone. The BRX zone was tested by nine drill holes on section lines spaced 150 to 225 m apart along a strike length of 1.3 km. Eight of the nine drill holes intersected significant gold-silver mineralization approximately 25 to 150 m down-dip of surface. The BRX zone has been traced over an aggregate strike length of 2 km by diamond drilling and excavator trenching and is open to extension along strike in both directions and down dip. The best drill intercept on the BRX zone in 2011 was 5.43 g/t gold and 50 g/t silver over 14.80 m (see news release dated November 2, 2011).

The BYG zone is a third zone on the property and parallels the Klaza zone, 125 m to the south. The zone demonstrates good grades with continuity along strike and down-dip. Nine of the 2011 diamond drill holes crossed the zone and all intersected significant mineralization, with the best interval grading 6.29 g/t gold and 342 g/t silver across 1.43 m. The BYG zone has been drilled along strike for 350 m and remains open for expansion in all directions.

Individual mineralized intercepts within the Klaza zone are comparable to those in the BRX and BYG zones, with narrower higher-grade intercepts in discrete linear structures that have been traced along the entire length of the drill tested areas. Bulk tonnage potential exists in parts of the Klaza zone, where increased fracturing and brecciation host mineralization across widths of 10 to 75 m.

Results from 2011 diamond drilling at the Klaza and BYG zones are shown in the table below with the significant Klaza zone intersections highlighted in bold text. These results are in addition to holes KL-11-12 to KL-11-20 which targeted the Klaza zone and were previously announced (see news release dated September 15, 2011). All drill hole locations, cross-sections, inclined longitudinal sections and a full compilation of drill hole results can be viewed on the Company's website at www.rockhavenresources.com.

Reconnaissance Exploration

Reconnaissance exploration was completed in a 3 km by 1 km area west of the known gold zones. This work included 4 diamond drill holes and 21 percussion drill holes, all of which targeted geophysical anomalies similar to those associated with the known zones. New discoveries were made in three holes.

Results from trenches that tested the western extension of the Klaza zone indicate that the zone bifurcates into a series of discrete gold bearing structures. Four trenches in this area, which were spaced 100 m apart, all intersected high grade gold and silver veins along strike of the Klaza zone. Vein exposures graded from 4.87 g/t gold and 634 g/t silver across 1.30 m to 1.25 g/t gold and 177 g/t silver over 9.00 m.

One trench that tested the eastern extension of the Klaza zone (TR-11-26) returned 7.17 g/t gold and 16 g/t silver over 7.11 m. It was cut 20 m east of the most easterly drill hole. Combined drill and trench results indicate a total known strike length of 1,100 m for the Klaza zone.

The Klaza property hosts four parallel, 1 to 75 m wide, structural zones of gold-silver mineralization. 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 zones exhibit features typical of both epithermal and mesothermal mineralization.

Core samples from the Klaza property were processed in 36 sample batches with each batch including two assay standards, two blank samples, and one duplicate sample. Trench and reverse circulation drill samples from the property were processed in 36 sample batches with each batch including one assay standards and one blank sample. Analytical work was done by ALS Chemex with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. All samples were initially analyzed for gold by fire assay followed by atomic absorption (Au-AA24) and 35 other elements by inductively coupled plasma-atomic emission spectroscopy (ME-ICP41). Overlimit values for gold were determined by fire assay and gravimetric finish (Au-GRA22) and silver values were determined 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.

The 2011 program was conducted by Archer, Cathro & Associates (1981) Limited. Technical information in this news release has been reviewed by Heather Smith, B.Sc., P.Geo., a qualified person for the purpose of National Instrument 43-101.
