VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 02/18/13 -- Woulfe Mining Corp. (TSX VENTURE: WOF)(OTCQX: WFEMF)(FRANKFURT: OZ4) ("Woulfe" or the "Company") -
Woulfe Mining Corp. reports that as a result of a review by the British Columbia Securities Commission (BCSC), it is issuing the following news release to clarify, retract, restate and update certain of its previously issued investor relations presentations, reports and disclosures on its website www.woulfemining.com.
The Company's website, including a corporate presentation, a fact sheet and investor's guide (the "Materials"), contained the following information, none of which invalidates any portion of, or requires any amendment in relation to, the Company's feasibility study on the Sangdong property as published June 6, 2012:
-- The Company's website and November 2012 Investor Guide (the "Guide") disclosed 2010 mineral resource estimates, completed as part of a scoping study (the "2010 Scoping Study"). The 2010 Scoping Study and mineral resource estimates have been superseded by a feasibility study on the Sangdong property having an effective date of June 6, 2012 and entitled "Sangdong Project Feasibility Study" (the "Feasibility Study"). The Feasibility Study was authored by TetraTech WEI Inc. and is available on the Company's SEDAR profile. It reports a Probable Reserve of 13.3 Mt @ 0.425% WO3 with a cut-off grade of 0.24% WO3. The Feasibility Study did not contain a complete mineral resource update, but converted a prior reported Indicated Resource of 16.4 Mt.@ 0.45% WO3 with a cut-off of 0.15% WO3 to the Probable Reserve reported above. The prior resource estimates on the Sangdong property, including the Indicated Resource referenced above, had an effective date of January 24, 2012 and were included in a report entitled "Sangdong Project Resource Estimate" authored by Wardrop, TetraTech WEI Inc (the "2012 Resource Report"). The 2012 Resource Report is available on the Company's SEDAR profile. The mineral resource estimates contained in the 2012 Resource Report are stated in the table below, noting that the Feasibility Study has converted the Indicated Resource to a Probable Reserve. It should be noted that the 2012 Resource Report states that the 2010 mineral resource estimates were made on a very different basis to the current (2012) estimates. The 2010 resource estimates largely relied on holes drilled underground by Korea Tungsten Mining Corporation and on a coarse geological interpretation of the mineralized zones. Because of doubts attaching to the location and sample quality control of these underground holes, and the limited geological understanding at the time, the 2010 mineral resources were classified in the Inferred category. The 2012 resource estimates rely entirely on modern drilling programmes with associated sample quality control. The modern data, however, covers only approximately the upper quarter of the known dip- length of the mineralized zones. For this reason, comparisons between the 2012 and 2010 mineral resource estimates should be treated with caution.Table Sangdong, Skarn mineralisation Resource Estimate; reporting cutoff0.15% WO3.----------------------------------------------------------------------------Resource Mineralized Tonnes WO3 MoS2Category Zone (Mt) Density (%)(i) (%)(ii) MTU----------------------------------------------------------------------------Indicated F2 2.298 2.98 0.63 0.04 1,448,000----------------------------------------------------------------------------Indicated F3 2.605 2.96 0.56 0.05 1,458,000----------------------------------------------------------------------------Indicated Halo 5.576 2.91 0.27 0.03 1,505,000----------------------------------------------------------------------------Indicated Main 5.952 3.25 0.50 0.03 2,976,000----------------------------------------------------------------------------Indicated(ii) Total 16.431 3.04 0.45 0.04 7,387,000----------------------------------------------------------------------------Inferred F2 2.680 2.91 0.50 0.03 1,340,000----------------------------------------------------------------------------Inferred F3 2.712 2.90 0.49 0.03 1,329,000----------------------------------------------------------------------------Inferred Halo 6.523 2.88 0.23 0.02 1,500,000----------------------------------------------------------------------------Inferred HW 7.191 2.96 0.58 0.08 4,171,000----------------------------------------------------------------------------Inferred Main 0.259 2.92 .052 0.02 135,000----------------------------------------------------------------------------Inferred Total 19.368 2.92 0.44 0.05 8,475,000----------------------------------------------------------------------------Inferred F2 4.097 2.85 0.60 0.07 2,458,000----------------------------------------------------------------------------Inferred F3 4.315 2.85 0.57 0.06 2,460,000----------------------------------------------------------------------------Inferred Halo 5.973 2.85 0.21 0.06 1,254,000----------------------------------------------------------------------------Inferred HW 15.924 2.84 0.69 0.11 10,988,000----------------------------------------------------------------------------Inferred Main 4.208 2.85 0.60 0.03 2,525,000----------------------------------------------------------------------------Inferred Down Total 34.519 2.85 0.57 0.07 19,685,000Dip---------------------------------------------------------------------------- Note: MoS2 is reported in terms of WO3 cut-off.

The resource is split into two sections by elevation, representing the down dip potential of the deposit below current waterline. The only current mineral resource and mineral reserve estimates that have been approved by or on behalf of the Company in relation to the Sangdong property are as stated above in the 2012 Resource Report and the Feasibility Study.-- The website and Materials contained aggregated resource numbers which added Inferred Resources to other categories of resources in respect of the Sangdong property, or which used a category of mineral resources, specifically "mineable resource", not permitted by NI 43-101 in respect of the Muguk property.-- The website and Materials discloses the results of economic analyses from the Company's feasibility study which may be misleading and/or unbalanced as the website and Material only reference pre-tax results without disclosing the comparative post-tax results. Investors are strongly encouraged to review the Feasibility Study in full.-- The Guide contained a reference to historical, non-43-101 compliant, resource estimates for the Sangdong Moly Stockwork. A non-NI 43-101 compliant historical resource estimate for molybdenum at the Sangdong property was reported by Korea Engineering Co. Ltd. in 2001 and a memo of Paul Matthews and Heywood Bates in 2008. A Qualified Person has not completed sufficient work in order to classify historical resource estimates for molybdenum on the Sangdong property as current mineral resources and the Company is not treating these historical estimates as prepared by Korea Engineering Co. Ltd. or Paul Matthews and Heywood Bates or otherwise as current mineral resources but as historical estimates. They are for informational purposes only and should not be relied upon.-- The website and Materials incorrectly references a 0.20% cut-off in relation to the 2012 resource estimates, where a 0.15% cut-off was used, as outlined above.-- The website and Materials failed to properly identify, and disclose the relationship to the Company, of the Qualified Person who approved, prepared or supervised the preparation of the technical information within. The Company has added this disclosure to its website and the Materials.
