June 11, 2010 - Rockhaven Resources Ltd.
(TSX-V:RK) (“Rockhaven”) is pleased to announce plans for 2010 exploration at its Klaza and Mount Hinton properties located in Yukon, Canada. The Company’s exploration budget for 2010 is $1.8 million. Both properties are road accessible and are favourably situated in established mining camps.
Exploration at the Klaza
property is about to commence and will include excavator trenching followed by diamond drilling. The property is located within the Mt. Nansen gold camp, a district that hosts an extensive system of gold-silver veins and gold-copper porphyry targets. Exploration in 2010 is designed to evaluate the continuity of the high grade gold-silver vein zones and to explore for bulk tonnage targets that are indicated by historical geophysical and soil geochemical surveys. Approximately 1500 m of diamond drilling and 10,000 m of excavator trenching are planned.
Three main zones have been discovered to date at the Klaza property. They are called the BRX, Klaza and BYG and are discussed in the following paragraphs.
The BRX Zone has been traced by closely spaced excavator trenches and diamond drill holes for a 750 m strike length. Most exposures grade between 3 and 6 g/t gold with 20 to 200 g/t silver across 1 to 2 m widths. Peak values include 28.11 g/t gold over 2.0 m and 1289.14 g/t silver across 1.7 m. The BRX Zone has been tested by 13 diamond drill holes with the best intersection averaging 6.27 g/t gold and 18.94 g/t silver over 8.9 m, including 1.5 m grading 24.51 g/t gold and 50.06 g/t silver.
The Klaza Zone is located 1000 m north of the BRX Zone and has been traced for a length of 250 m. Mineralized intervals exposed in excavator trenches returned assays ranging between 0.82 to 43.06 g/t gold and 3.17 to 521.14 g/t silver across widths of 0.80 m to 8.0 m. A total of 11 separate exposures from 3 trenches returned a weighted average of 8.11 g/t gold and 123.35 g/t silver over an arithmetic average width of 2.11 m. Only one diamond drill hole has tested this zone and it yielded 3.82 g/t gold and 84.70 g/t silver over 5.05 m.
The BYG Zone is located approximately midway between the other zones. It has only been explored with two trenches located 180 m apart and one diamond drill hole. The best trench assay was 6.03 g/t gold and 24.00 g/t silver over 3.3 m. A diamond drill hole beneath this trench intersected several quartz±sulphide bands, the best of which returned 4.80 g/t gold and 23.70 g/t silver over a 1.0 m interval.
All three zones are open to extension along strike in both directions and to depth.
Initial exploration at the Mount Hinton
property will consist of detailed soil geochemical sampling and prospecting followed by excavator trenching. The property is situated within the eastern part of the Keno Hill Mining Camp, a district that hosts more than 35 individual mines and is historically Canada’s second largest primary silver producer. Although silver mineralization is found in veins on the Mount Hinton property, gold is the most significant component in many of the 72 bedrock showings and float occurrences that have been discovered on the property by previous operators. The 2010 program will focus on defining targets that are on trend with showings located on the adjacent Keystone property owned by Aldrin Resource Corp. and the Bellekeno Mine owned by Alexco Resource Corp. Diamond drilling is expected to be conducted in late August or September to follow up positive results from the initial work program.
Rockhaven acquired a 100% interest in the Klaza property from ATAC Resources for cash and shares. It has the optional right to earn to earn 100% interest in the Mount Hinton property from arms-length private parties. A 2% net smelter return royalty (NSR) is retained by a third party on 297 of the 400 claims that comprise the Mount Hinton property. That NSR can currently be purchased outright for $115,000.
