Rockhaven Resources Ltd. Announces Remaining Assays From Excavator Trenching at Its Klaza Property
October 19, 2010 - Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce assays from the remainder of its 2010 excavator trenching program at its wholly-owned Klaza property, which is located in the Dawson Range Gold Belt of central Yukon Territory. A total of 8000 m of trenching done during the program expanded known zones and made significant new discoveries. Results are expected soon from 11 diamond drill holes that tested downdip of high grade vein and bulk tonnage, gold and silver mineralization exposed in trenches across the various zones.
Excavator trenching has only been done in approximately 10% of the 30 sq km property. It has proven to be a highly effective exploration technique and has exposed a series of four main, northwest trending structural zones, named the Klaza, BYG, Herc and BRX. Each structural zone hosts a series of mineralized veins and breccias, individually ranging between 0.5 to 10 m in width. Lateral continuity of the zones is excellent. They vary from 10 to 50 m in width and have been traced between 500 to 1000 m along strike. All of them are open to further extension.
The most consistent results are from the Klaza Zone where broad intervals of strongly elevated gold and silver assays have been reported (news releases dated August 25th and September 21st, 2010). New trench results extend the Klaza Zone to a length of 500 m. Trench KL-10-19, which exposed the Klaza Zone 125 m west of the previously announced KL-10-10 (2.87 g/t gold and 42.3 g/t silver over 20.10 m), encountered a narrower but better grade interval that assayed 12.45 g/t gold and 305.0 g/t silver over 1.45 m. The mineralization narrows in this trench because most of the zone is occupied by an uncommonly thick dyke of intrusive rock. Similar dykes are present elsewhere in the zone. They are often flanked by mineralization but are themselves barren. These dykes pinch and swell in three dimensions and there is no reason to believe that this dyke has cut off the mineralization. Coincident soil geochemical and geophysical anomalies have been identified along trend of the Klaza Zone in both directions from the trenches. Prospecting along the anomalous trend is usually ineffective because of vegetation and overburden cover; however, four clusters of mineralized float were discovered in a 75 m diameter area approximately 200 m west of KL-10-19. Four composite samples collected from this area returned between 0.10 to 4.76 g/t gold and 129 to 781 g/t silver. Pre-stripping of vegetation and overburden has been done in several areas along trend of the Klaza Zone in preparation for continued trenching in 2011.
Trenching elsewhere on the property also yielded positive results. KL-10-21, located along the western extension of the BRX Zone, made a particularly encouraging discovery, which averaged4.00 g/t gold and 434.8 g/t silver over 8.68 m. New results from other trenches on the property include:
In general, silver values are increasing as trenching proceeds northwesterly away from the original discovery area.
The Company has posted a table summarizing results from the entire 2010 excavator trench program along with a map showing excavator trench locations at www.rockhavenresources.com.
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 is situated 10 km from the historical Mt. Nansen gold mine and is flanked to the east and west by active placer gold mining operations.
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 are 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 exceed detection limits for silver, lead or zinc are also assayed by gravimetric methods (Ag/Zn/Pb-OG62). All standard and blank samples passed QAQC reviews.
The 2010 program was 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.
