November 30, 2009 - Rockhaven Resources Ltd.
(TSX-V:RK) (“Rockhaven”) is pleased to announce results from 2009 exploration at its wholly-owned Groundhog property located in south-central Yukon Territory. The property is road accessible and consists of 120 mineral claims covering a 23 kmĀ² area. It is located in a belt of gold and silver occurrences that include the former Ketza Gold Mine, 30 km to the east, and the Tay-LP gold prospect, 11 km to the southeast.
The 2009 exploration program re-examined a number of historical silverĀ±leadĀ±zinc showings on the property. It also included reconnaissance-scale prospecting and soil geochemical sampling, which resulted in a promising new gold discovery that is described in the following paragraphs.
The most important discovery made at the Groundhog property in 2009 is a broad zone of anomalous gold and arsenic values located near the centre of the claim block. This discovery, called the Aztek Zone, was not identified by previous operators and is loosely defined by widely spaced soil sampling. The anomalous zone forms an oval about 2000 m long and up to 1400 m across. The historical silverĀ±leadĀ±zinc showings occur peripheral to the gold-arsenic zone. Anomalous soil values within the zone range between 25 and 327 ppb gold and 77 to 1940 ppm arsenic.
The Aztek Zone is mostly underlain by a dolomite unit that is in the footwall of a regional-scale thrust fault. The dolomite is cut by steeply dipping faults and narrow andesite dykes. This setting is favourable for carbonate-replacement or manto-type gold mineralization. The most significant deposits of this kind in Yukon are the Ketza Deposit, owned by Yukon-Nevada Gold Corp., and the Rau Deposit, which was recently discovered by ATAC Resources Ltd. Similar mineralization was recognized at the Groundhog property with the discovery of limonitic dolomite rubble found in an old bulldozer clearing within the newly recognized gold zone. A grab sample of the limonitic material returned 1.81 g/t gold, 486 g/t silver, 14.90% lead and 0.75% zinc. These assays and the results of the soil sampling were all received after the crew left the property, and no follow up exploration has been done.
Discovery of gold mineralization at the Aztek Zone prompted the Company to add 12 claims to the Groundhog property and to stake two nearby claim blocks, the Cyr and the Grayling properties. The Cyr property is located 2 km east of Groundhog and covers a 6.6 kmĀ² area. This property is road accessible and hosts showings that have been tested by limited diamond drilling and hand trenching by previous operators. The Grayling property lies 13 km southeast of the Groundhog property and covers a 4.2 kmĀ² area. It is marked by strongly anomalous gold (48 ppb), silver (4.0 ppm), arsenic (8800 ppm), lead (855 ppm), and zinc (1500 ppm) values from a regional-scale stream sediment sampling survey.
“The new discovery at the Groundhog property continues the Company’s exceptional string of recent successes” says Rockhaven’s CEO Matt Turner. “Future exploration at the property will be stimulated by the recognition of gold mineralization in this highly prospective setting.”Multi-element determinations for soil and rock samples were carried out at ALS Chemex in North Vancouver, B.C. Soil samples were dried and sieved to -80 mesh. The fine fraction was then analyzed for gold using fire assay followed by atomic absorption (AA) finish and for 34 other elements using a nitric acid-aqua regia digestion and ICP analysis. Rock and chip samples were dried, fine crushed to better than 70% passing -2 mm and then a 250 g split was pulverized to better that 85% passing 75 micron. The fine fraction was analyzed for gold and 34 other elements using the same procedures as were used for the soil samples.
