Woulfe Mining First New Drill Results from Sangdong
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/19/11 -- Woulfe Mining Corp. ('Woulfe' or the 'Company') (TSX VENTURE: WOF) announces drill results from the initial three underground holes of a 38 hole drilling program in progress at its Sangdong tungsten-molybdenum project in South Korea.
As previously announced, this drilling program is targeting the unmined ore in the upper portion of the mine. This Main Zone is made up of the inclined shaft, infrastructure pillars, the Hangingwall and Footwall Zones above the current water level. 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.
Brian Wesson, CEO/President of Woulfe, commented from site in Korea that: 'Spring has arrived and we are now working unhindered to achieve our goals of completing the drilling, mine plan, feasibility and detailed design this year. We are working on the geology and mining plan with personnel from Wardrop as we progress the project'.
The central Main Zone, being high grade, was largely mined out during previous production apart from support pillars and protective areas around infrastructure mainly in the top and margins of the lodes. The overlying Hangingwall Zone and underlying Footwall Zone are largely intact. The National Instrument 43-101 resource estimate undertaken in early 2010 by Wardrop UK (a Tetra Tech Company) ('Wardrop') as part of the Scoping Study, totalling 103.2 million tonnes at 0.35% WO3 and 0.04% MoS2, based on a cut-off grade of 0.1% WO3, included only the Hangingwall and Footwall Zones.
Refer to press release titled 'Woulfe Mining Corporation, Sangdong Project, Scoping Study', dated April 2010, by Wardrop, available on Woulfe's website, for further technical information on the project.
The large infrastructure protective pillar supporting hoist chambers, inclined shafts and the main haulage level which traverses the top of the mine and both flanks down-dip. There is very little historical drilling data within this pillar as it was not considered a potential source of ore. Woulfe now understands that the high grade Main Zone has only been partially mined within the upper portion of the mine. The objective of the current drilling program is to define the resources above the water level for feasibility reserve estimation and mine planning purposes.
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.
Further drilling results will be released on a regular basis as they are received now that all drilling, geology and sample preparation procedures are in place.
The initial three holes comprise:
WSDD0022A - Collar 4111472N, 485283E, Azimuth 166.3, Dip 50.3, Depth 55
metres, Target F/W
WSDD0023A - Collar 4111479N, 485280E, Azimuth 363.4, Dip 32.6, Depth 152
metres, Target F/W
WSDD0025A - Collar 4111506N, 485316E, Azimuth 342.2, Dip 0.5, Depth 18.1
metres, Test hole
The three holes reported here targeted the Footwall Zone. The Footwall Zone comprises a number of alteration zones separated by unaltered partings. Historical information indicates that the Footwall Zone has a lower average grade than both the Main and Hangingwall Zones. All three holes are located on the eastern margin of the skarn which historical information indicates as having a lower grade than the central zone. The reasons for testing the Footwall Zone on the margin of the skarn with the initial holes were due to access limitations and the ability to drill down-holes only at the start of the drilling program. These limitations have now been overcome and extensive drilling has now taken place across the entire area.
These initial results are encouraging since the holes were drilled on the margins of the skarn that historical information indicates as having a lower grade than new results show. WSDD0025A was a short test hole drilled to commission the underground electric rig. The other two holes were drilled using the air-powered Kempe rigs.
All significant drill intercepts, defined as any mineralisation of 1 metre lengths or longer, are presented in the following table. It should be noted that some of these intercepts are narrow and will almost certainly be less than the minimum mining width.

The test hole WSDD0025A was terminated at 18.1 metres in high grade mineralisation (last intersection 1.1 metres at 1.90% WO3) in what is interpreted to be the F1 Footwall vein immediately underlying the Main Zone. Further interpretation work is required to determine the Footwall veins intersected by holes WSDD0023A and WSDD0022A.
Woulfe is utilising seven rigs to accelerate the program to offset the delayed start due to restrictions caused by equipment delays and the severe winter. This includes four contract surface rigs, a contract underground machine and two Company-owned underground machines, mostly working around the clock. On the 12th April 2011, some 3000 metres of the 5000 metre drilling program (60%) had been achieved. The drilling is on track to be completed by the end of May and an updated NI 43-101 resource statement is to be published by end June to underpin the Feasibility Study.
Woulfe appointed Mr Don Smith in January as Manager Geology. Mr Smith is a Member of the Australasian Institute of Mining and Metallurgy and has sufficient experience to conduct the drilling program and to manage the relevant geological, sampling and assaying processes. This news release has been reviewed and approved in the form and context in which it appears by Woulfe's Canadian-based geological advisor, Mr. Pat Stephenson, P.Geo, of AMC Mining Consultants (Canada) Ltd. Mr. Stephenson has appropriate qualifications and sufficient relevant experience to qualify as a Qualified Person for the reporting of exploration results for the Sangdong deposit.
