Woulfe Mining has reported assay results from the six and seven set of samples connected with the phase 1 drilling completed recently at the Sangdong tungsten mine.
The molybdenum-tungsten mineralization at Sangdong is present in three analogous, shallow-dipping skarn zones, namely Main, Hangingwall and Footwall, with a lateral area of up to 1,500 m down dip and 1,200 m along strike.
The company has intersected 0.99% WO3 over 8.0 m in the hole SD 97 at the Main zone, 0.87% WO3 over 17.3 m and 0.56% WO3 over 12.0 m in the hole SD 97 at the Hangingwall zone and 0.68% WO3 over 8.2 m in the hole SD 95 and 0.36% WO3 over 15.6 m in the hole WSDD0027 at the Footwall zone.
The company’s drilling program has targeted the mineralization, which is unexplored, in the mine’s upper part above the existing water level for the purpose of mine planning and feasibility reserve evaluation. Woulfe has received 103.6 mt as Inferred Resource at 0.04% MoS2, 0.35% WO3 at a cut-off of 0.1% WO3 through the 2010 March Wardrop Engineering Scoping Study. This resource estimate combined the group of Footwall mineralized zones as a unit and the Hangingwall Zone as an additional unit. It will not include any residual mineralization from the Main zone.
The assay results of the batches six and seven has included seven holes, which contains five surface holes and four were drilled to outline the deposit’s western margin. The location of SD 92, the fifth surface hole, is in the central part of the deposit to describe the Hangingwall zone.
The company has prepared the samples on-site in Korea and sent for analysis to SGS Perth, Australia. inductively coupled plasma mass spectrometry (ICP) examines the samples and aqua regia or 4-acid digestion tests the for ore-grade quantities of definite elements. Molybdenum is examined by X-ray fluorescence.
