VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 11, 2011) - Rockhaven Resources Ltd. (News - Market indicators) (the "Company" or "Rockhaven") is pleased to announce that three drills and a large excavator are currently working at its wholly-owned, road accessible Klaza bulk tonnage gold-silver discovery in the Dawson Gold Belt, Yukon.
The Klaza property hosts four parallel, 5 to 50 m wide, structural zones of epithermal-type gold-silver mineralization. All zones consist of quartz-sulphide veins, breccias and fracture networks that are spatially associated with quartz-feldspar porphyry dykes that intrude granitic country rocks. Four laterally contiguous zones have been defined within a 1500 m wide, northwesterly trending structural corridor. The area that has been explored by trenching and drilling represents less than 5% of the 60 sq km property. Geochemical and geophysical anomalies extend well beyond the area of trenching and drilling.
Current work is focused on expanding the Klaza zone discovery which is the widest and most consistently mineralized zone. In late 2010, three drill holes tested below discovery surface trenches and returned grades of:

At present, two drills are concentrating on definition drilling the discovery along a confirmed 500 m strike length of the Klaza zone. A third drill and excavator are testing new targets along strike of the Klaza zone and the three other parallel zones (BRX, HERC and BYG).
- 20 drill holes (4,000 m) have been completed on the Klaza property to date. Detailed drilling has tested the Klaza zone at 50 m drill centres, along 250 m of strike and to a depth of 200 m down-dip from surface. Assays are pending.
- Mineralized intercepts appear similar in width to those seen in the 2010 drill program.
- Visual descriptions of mineralized intercepts appear consistent with the nearby 2010 drill holes.
- Surface trenching confirms the zone remains open along strike in both directions.
- Drill intercepts confirm the mineralized system is open for expansion to depth. A large drill may be brought in to define the down-dip extension below 200 m.
Please note that assays are not yet available for any of the 2011 drill core. Those assays will be released in batches, after all samples from each group of holes passes QA/QC protocols.
By fall 2011, Rockhaven expects to continue drilling at the current pace and complete more than 8,000 m of trenching on the Klaza property. A map showing completed and planned holes can be viewed on the Company's website.
The 2011 program is being 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.
