Rockhaven Resources Ltd. Discovers Large Gold-In-Soil Targets at Mount Hinton, Yukon

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 16, 2011) - Rockhaven Resources Ltd. (TSX VENTURE:RK) ("Rockhaven") is pleased to announce the results from its 2010 soil sampling program on the Mount Hinton property located in the Keno Hill mining camp in central Yukon Territory. The property hosts gold-silver-lead mineralization within steeply dipping vein structures.

Highlights from the 2010 program are:

  • A 25 to 100 m wide gold and silver soil geochemical anomaly traced over 1 km and on trend with a known precious metal bearing structural zone at the #5 Vein
  • Strongly elevated gold-in-soil results from the Granite Creek Basin including a 500 by 600 m area hosting between 50 and 3310 ppb (0.05 to 3.31 g/t) gold in 40% of the samples collected

The Mount Hinton property is directly accessible by a 10 km all-weather road from Keno City and consists of two claim blocks that total 400 mineral claims and cover 82 sq km. The Yukon's hydroelectric power grid extends to Alexco Resource Corp.'s Bellekeno deposit, which is located 3 km north of the Mount Hinton claim block and lies along a road system that accesses the northern part of the Mount Hinton property.

The 2010 exploration program included the collection of approximately 1600 auger soil samples from three areas on the property: #5 Vein, Granite Creek Basin and #1 Vein. The results are described below and maps are posted on Rockhaven's website. 

The #5 Vein is located in the south-central part of the property. Historical work included percussion drilling and excavator trenching within a 100 by 600 m area at the top of a ridge where the vein is exposed at surface. This work identified a 20 m wide structural zone hosting anomalous gold and silver mineralization. The 2010 work outlined a soil geochemical anomaly that extends 1080 m southwest along strike from the vein exposure in a previously unexplored part of the property. This anomaly is 25 to 100 m wide and features strongly elevated gold (10 to 171 ppb), arsenic (31 to 681 ppm), silver (0.2 to 4.1 ppm), and antimony (4 to 61 ppm) values. Geological mapping and prospecting indicate that the anomaly is associated with brittle rock units, which are particularly favourable for vein development.

The Granite Creek Basin target is situated in a valley immediately northeast of the #5 Vein. This target was originally identified in 1965 when silt samples taken from the valley during a district-wide geochemistry program conducted by the Geological Survey of Canada returned the strongest gold-in-silt anomalies within the Keno Hill mining camp. Despite these very encouraging results, no systematic exploration has been conducted at this target. Auger soil sampling conducted by Rockhaven in 2010 identified a 500 by 600 m soil geochemical anomaly within which 40% of the samples yielded strongly anomalous values between 50 and 3310 ppb (0.05 to 3.31 g/t) gold. 

The #1 Vein is located in the eastern part of the property about 4 km northeast of the #5 Vein. Historical work at the #1 Vein consisted of four excavator trenches and two diamond drill holes. Reinterpretation of the geology indicates the holes tested a bedding plane fault, not one of the transverse vein structures which are known to host the most significant vein occurrences in the Keno Hill mining camp. Prospecting by United Keno Hill Mines in 1966 at the #1 Vein discovered galena float boulders grading 30,822 g/t (or 899 oz/ton) silver and 14,400 g/t (or 420 oz/ton) silver. The source of this material has never been located. The best soil sample from 2010 work on this target was collected 600 m northeast of the drill area along the projected trace of the vein structure. It returned 93.2 ppm silver and 1185 ppm lead.

Rockhaven is currently seeking a joint venture partner to advance the Mount Hinton property as it intends to remain focused on its wholly-owned Klaza property.

The Mount Hinton 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. Creeks draining the property have yielded significant placer gold production and are still being mined.

Rockhaven can acquire 100% interest in the Mount Hinton property by making cash payments totaling $500,000 over a three year period to an arm's length syndicate. Rockhaven has completed the first cash payment of $166,000. A 2% net smelter return royalty retained by a third party on 297 of the claims was recently purchased by Rockhaven.
