Woulfe Mining's Sangdong Tungsten Project Drill Results Offer Significant Encouragement
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 06/01/11 -- Woulfe Mining Corp. ('Woulfe' or the 'Company') (TSX VENTURE: WOF) is pleased to announce assay results for the fourth batch of nine batches of samples associated with the now completed drill program. As previously announced, the drilling program targeted the unmined mineralisation in the upper section of the mine above the current water level for mine planning and feasibility reserve estimation purposes.
The tungsten-molybdenum mineralisation at Sangdong is hosted within three parallel, shallow-dipping skarn zones (Main, Hangingwall and Footwall) with a lateral extent of up to 1,200 metres along strike and 1,500 metres down dip.
The work programme is focused on upgrading part of the current NI 43-101 compliant Inferred Resource to an Indicated Resource that in turn has sufficient confidence to be converted to a mineral reserve as part of the feasibility study to be completed later in the year. The four batches reported today have returned very encouraging grades of tungsten (WO3) and MoS2. The updated NI 43-101 resource estimate is targeted for release at the end of June 2011. Woulfe has commissioned Wardrop Engineering to produce the new resource estimate and complete the feasibility study, and has also engaged AMC Mining Consultants (Canada) Ltd as geological advisors.
The 2010 March Wardrop Engineering Scoping Study produced an Inferred Resource of 103.6 million tonnes at 0.35% WO3, 0.04% MoS2 at a cut-off of 0.1% WO3. This resource modelled the group of Footwall mineralised zones as a combined unit and the Hangingwall Zone as another unit. Any remaining mineralisation from the Main Zone was not included. This resource was classified as Inferred primarily because of reliance on the historical underground drilling. The current surface and underground drilling programmes will improve confidence in the estimate, potentially allowing it to be classified as Indicated Resources.
The recent drilling results are summarised as below:

Significant drill intercepts, defined as any mineralisation of 1 metre lengths or longer, are presented in the tables above. A cut-off of 0.15% WO3 was used for the intersection calculations.
To date the two best intersections in the Main Zone are WSDD0014, 45.5 metres (true width 41.2 metres) at an average grade of 0.61% WO3 and WSDD0015, with an intersection of 39.0 metres (true width 18.3 metres) at an average grade of 0.91% WO3.
The initial drilling program has been completed. The reopening of the levels above One Level, that is the area targeted for initial mine production, has identified large areas that have not been drilled in the Main and Hangingwall Zones. A second drilling program is now planned to explore the potential of these areas. These holes may be used for the updated NI 43-101 resource estimate planned for completion at the end of June if the results are available in time.
The samples are prepared on-site in Korea to appropriate industry standards and sent to SGS Perth, Australia for analysis. Samples are analysed by Inductively Coupled Plasma Mass Spectrometry (ICP) and for ore-grade quantities of specific elements by aqua regia or 4-acid digestion followed by ICP analysis. Molybdenum is analysed by X-ray fluorescence. The QA/QC protocol comprises insertion of one standard, one blank (crushed glass) and one pulp duplicate in every batch of 20 samples. No QA/QC results are available as yet.
This news release has been reviewed and approved in the form and context in which it appears by Mr Paul Gribble FIMMM, C.Eng, of Wardrop, who is working with Woulfe on the Sangdong studies. Mr Gribble has appropriate qualifications and sufficient relevant experience to qualify as a Qualified Person for the reporting of exploration results for the Sangdong deposit.
