Rockhaven Resources Ltd. Announces 2011 Exploration Commences at Klaza Gold Silver Project, Yukon

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 18, 2011) - Rockhaven Resources Ltd. (TSX VENTURE:RK) (the "Company") is pleased to announce that the 2011 exploration program has commenced on the Klaza property, located in the Dawson Range Gold Belt of central Yukon Territory. The Klaza property hosts gold and silver mineralization within steeply dipping, parallel structural zones.

Crews have been mobilized to the property and drilling is scheduled to start by month end. Three drills have been contracted to conduct approximately 12,000 m of diamond drilling at Klaza as part of the 2011 phase I exploration program. The Company has access to additional drills if warranted. In 2010 drilling and trenching results identified broad areas with precious metal mineralization in multiple structures across the property which have been traced along strike for 500 to 1000 m and all are open to extension. The mineralized zones can be followed by magnetic and electromagnetic anomalies. Historical geophysical and geochemical results suggest an additional 5.5 km of strike may exist to the northwest.

A 6,000 m excavator trenching and detailed soil sampling program will run concurrently with the drill program on the main Klaza gold-silver zones. Additional soil geochemical and geophysical surveys will be conducted further along trend to the northwest to assess the 30 sq km of new claims that were staked in fall 2010 along trend.

Initially two drills will be used to test the Klaza zone, which has been traced for 500 m on surface. This discovery is open to extension along strike in both directions and to depth. The objective is to establish continuity over the 500 m of known mineralized strike length and grid drill the discovery to a minimum depth of 200 m from surface.

A third drill will be used for scout drilling to evaluate the strike extensions of the Klaza zone and the other mineralized zones on the property. The phase I exploration program is budgeted at $6 million. The Company currently has approximately $11 million in its treasury.

The Klaza property is situated in an active placer gold mining camp and historical hard rock gold and silver mining district. Systematic excavator trenching and widely spaced diamond drilling have only been done in approximately 5% of the 60 sq km property. Four laterally contiguous zones have been defined within a 1500 m wide, northwesterly trending structural corridor.

The 2011 program will be 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.
