BRITISH COLUMBIA - Vancouver's SULTAN MINERALS has rediscovered the East Emerald tungsten zone at its Jersey-Emerald property near Salmo. The tungsten-bearing horizon has been shown by historical drilling and surface sampling to be more than 1,100 metres long and to extend up to 300 metres down-dip. Drill logs show that the zone ranges from 1.2 metres to more than 20.0 metres in thickness, with tungsten assays varying from less than 0.10% WO3 to greater than 0.28% WO3. The zone remains open to the south.
The four holes that Sultan reported this week assayed thus: 0.14% WO3 over 7.3 metres, 0.15% over 14.3 metres, 0.15% over 16.6 metres, and 0.07% over 7.6 metres. All holes also returned molybdenum values of between 0.02 and 0.05% MoS2. (Further details are available at www.SultanMinerals.com.)
The Jersey-Emerald property includes the Emerald mine (Canada's second largest tungsten mine) and the adjoining Jersey mine (the largest zinc producer in the Kootenay area). The Emerald mine was put into production in 1943 by a Crown corporation, Wartime Metals, in order to provide tungsten for the Second World War. In 1947, the mine was sold to Canadian Exploration (a subsidiary of PLACER DOME) and was Placer Dome's first underground mining operation. Placer Dome mined the property alternately for tungsten and lead-zinc until 1973 when it closed due to low metal prices. When the mine closed, Placer's records reported six unmined tungsten targets in the vicinity of the historic mine workings. The targets occur as broad linear bands that extend for more than 1,500 metres to the north and to the south of the former tungsten workings. Most of these zones are accessible from the existing mine workings and are therefore important drill targets for future exploration.
