Rockhaven Resources Ltd. Announces 2012 Exploration Plans at Klaza, Yukon13:15 EDT Monday, June 04, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 4, 2012) -Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce its 2012 exploration plans for its wholly-owned and road accessible Klaza property, located in the Dawson Range Gold Belt of central Yukon Territory. Crews have been mobilized to the property and drilling is scheduled to start in early June. Two drills have been contracted to conduct approximately 8,000 m of diamond drilling at Klaza as part of the 2012 Phase I exploration program. This program is fully funded by Rockhaven, which has access to additional drills if warranted. Drilling and trenching by Rockhaven in 2010 and 2011 identified four parallel structural zones hosting epithermal to mesothermal-type gold-silver mineralization. All zones have been traced along strike for 500 to 2,000 m and all are open to extension. The known zones are marked by magnetic lows and soil geochemical anomalies. Several similar anomalies occur elsewhere on the 60 sq km property and will be tested by drilling or trenching for the first time in 2012.The 2012 Phase I program is focused on expanding the Klaza and BRX zone discoveries. The Klaza zone has been traced by drilling and excavator trenching for 1100 m along strike and to a depth of 250 m down dip. The BRX zone has been tested by widely spaced diamond drilling and excavator trenching with mineralization identified over a length of 2,000 m. It has only been tested to a maximum depth of 150 m. Both zones remain open in all directions and to depth, with some of the strongest drill hole and trench values at the open ends of the zones. Significant mineralization has been cut in 36 of 40 holes drilled at the Klaza zone and 10 of 11 holes drilled at the BRX zone.

They are gross in-situ metal values that do not account for less than complete metallurgical recoveries or costs related to extraction, smelting, refining or taxes.Concurrent with the drilling, approximately 5,000 m of excavator trenching will be conducted along strike of the known zones and to test other targets on the property. Soil geochemical surveys and prospecting will also be completed in other areas of the property to define additional targets for drilling or trenching.All significant assays from 2010 and 2011 diamond drilling can be viewed on the Company's website (www.rockhavenresources.com), including a 3D model, geological cross-sections and assay histograms.The 2012 program will be managed by Archer, Cathro & Associates (1981) Limited.
