Rockhaven Resources Ltd. Announces Expansion of the Klaza Zone and Discovery of a New Zone at Its Klaza Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2010) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce additional assay results from 2010 excavator trenching on its wholly-owned Klaza property located in the Dawson Range Gold Belt of central Yukon Territory. The program continues to be successful, discovering high-grade vein and bulk tonnage bedrock exposures and visually promising diamond drill results.

New trench results extend the Klaza Zone to a length of 375 m, and the zone remains open to further extension along strike in both directions and downdip. Trenches KL-10-11 and KL-10-12 tested the Klaza Zone to the east of the previously announced KL-10-10 (2.88 g/t gold and 42.1 g/t silver over 20.10 m) and KL-10-09 (2.33 g/t gold and 34.91 g/t silver over 16.35 m). The main intervals from the new trenches are:

  • 2.56 g/t gold and 30.4 g/t silver over 17.70 m in KL-10-12; and

  • 2.64 g/t gold and 10.6 g/t silver over 4.67 m and 2.04 g/t gold and 18.7 g/t silver over 5.40 m in KL-10-11.

Through trenching, another substantial discovery was made at the Herc Zone, located 400 m south of the Klaza Zone. Chip samples from the discovery trench at the Herc Zone average 3.06 g/t gold and 48.5 g/t silver over 7.60 m. This discovery has not yet been followed up by additional excavator trenching or diamond drilling.

New results from other zones on the property include:

  • 1.35 g/t gold and 33.4 g/t silver over 14.50 m;

  • 1.93 g/t gold and 136.5 g/t silver over 7.80 m;

  • 2.92 g/t gold and 140.0 g/t silver over 4.50 m;

  • 0.79 g/t gold and 391.8 g/t silver over 3.00 m;

  • 1.52 g/t gold and 31.2 g/t silver over 5.22 m;

  • 1.95 g/t gold and 82.6 g/t silver over 2.65 m;

  • 2.78 g/t gold and 9.9 g/t silver over 3.00 m;

  • 2.50 g/t gold and 106.0 g/t silver over 2.00 m;

  • 2.58 g/t gold and 12.5 g/t silver over 2.10 m;

  • 0.97 g/t gold and 282.9 g/t silver over 1.80 m;

  • 3.28 g/t gold and 7.9 g/t silver over 2.00 m;

  • 2.44 g/t gold and 5.8 g/t silver over 2.00 m; and

  • 2.33 g/t gold and 33.0 g/t silver over 1.50 m.

A helicopter-borne magnetic and radiometric survey has been completed across the property to access the geophysical signatures of the known zones and to identify other areas of similar signatures elsewhere on the property. Detailed soil geochemical surveys have also been completed across the inferred strike projections of the Klaza and Herc Zones. The data from these surveys will aid in future exploration of the property.

The Klaza property is located 50 km west of Carmacks and is accessible by a two-wheel drive road from the Klondike Highway. The property has been recently expanded to 30 km2 through the staking of 34 additional mineral claims. These claims cover projected extensions of the vein zones.

Diamond drill holes and excavator trench locations appear on a plan map that can be seen at www.rockhavenresources.com.

"Rockhaven is very encouraged by the results from the 2010 work program and is optimistic that further exploration will expand the known zones and lead to additional discoveries," says Rockhaven's CEO Matt Turner. "Assays from diamond drilling and further excavator trenching are expected within a month."

Chip samples are being processed in 36 sample batches with every third batch including an assay standard and blank. Analytical work is being done by ALS Chemex with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. The 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). Samples that exceeded detection limits for silver, lead or zinc were assayed by gravimetric methods (Ag/Zn/Pb-OG62). All standard and blank samples passed QAQC reviews.

The 2010 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.
