Woulfe Mining's' gold project resource increase and project economic for development
Vancouver, BC, Canada -- May 2nd 2012 -- Woulfe Mining Corp. ("Woulfe" or the "Company") (TSX-V: WOF, OTCQX: WFEMF, Frankfurt: OZ4) is pleased to announce that the Inferred Resource in the Three Brothers vein (one of nine mineralized veins within the project area) has increased to 900,000 tonnes grading 10 g/t gold at a cut-off of 4 g/t gold with a minimum mining width of 1.2 meters (approximately 289,000 ounces). The mineralization also contains silver, but silver has been excluded from the mineral resource estimate due to a lack of data and was not modeled as part of the Preliminary Economic Assessment (PEA).
Some areas of the vein that were previously considered not to have reasonable prospects of economic extraction are now considered to be potentially mineable due to a revised access strategy that AMC has developed as part of the PEA. These additional areas have sufficient sample support to be included in the Inferred Resource. Additional production data from the period 1992 to 1996, demonstrates that the mined ore bulk density was generally 2.7 t/m3 and this has been used in the current mineral resource estimate. This differs from the 3.5 t/m3 originally stated by Woulfe, and the 3 t/m3 used by AMC in the 10 January 2012 release. AMC has also increased the cut-off grade from 3 g/t gold to 4 g/t gold to make it consistent with the PEA.
Figure 1 shows the area of the Inferred Resource colored in red. The main reasons for the difference to the Inferred Resource released on10 January 2012 are:
The net effect of these changes is to increase the tonnes and lower the grade of the Inferred Mineral Resource relative to the 10 January 2012 release from 520,000 tonnes at 11 g/t gold to 900,000 tonnes at 10 g/t gold.
- The proposed decline access strategy allows smaller and more dispersed packages of the resource to potentially be mined relative to the original shaft access strategy. Addition of the smaller packages of the resource has increased
- The bulk density has been changed from 3 t/m3 to 2.7 t/m3. Decreasing the bulk density has decreased the tonnage by 90,000 tonnes, with no change in the gold grade.
- The change in cut-off grade from 3 to 4 g/t gold. Increasing the cut-off grade has decreased the tonnage by 5,000 tonnes, with no significant change in the gold grade.

NB: AMC Consultants considered the economics of only one vein in the field of nine veins in the Preliminary Economic Assessment. On this basis alone the assessment indicated it is economic to reopen the field. The update of the Inferred Resource is principally a result of the PEA access method and the increased Inferred Resource does not imply that the PEA requires updating.
The financial metrics of the project are summarized below:
NPV (8% discount rate): US$31.8 million
Gold price: US$1,600
Mine life: 7 years
Production rate: 145,000 tonnes per annum
Average gold recovered per annum: 26,000 ounces
Operating cost: US$676 per ounce
Woulfe cautions that the PEA is preliminary in nature. It is based on an inferred mineral resource. Inferred resources are based on limited information, and grade continuity has been assumed, but not verified. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource that is the subject of the PEA will be converted into mineral reserve. No mineral reserves were estimated as part of the PEA.
Mr. Brian Wesson, CEO of Woulfe, comments that AMC Consultants has assessed the economics of one vein of nine at Muguk and have shown that it is economic to open Muguk to unlock the upside potential in the Three Brothers vein on strike and down dip and in the other veins in the field. Our recent focus has been the Sangdong project that is moving forward into construction. Muguk will now be moved forward as our exploration staff is freed up from Sangdong and the permanent staff takes control. Sangdong now has 65 staff.
The AMC resource estimate has been reviewed and approved in the form and context in which it appears by Woulfe's geological advisor, Dr Andrew Fowler M.AIG, MAusIMM, PhD, BSc (hons), of AMC Consultants Pty Ltd and Woulfe's mining engineering advisor, Mr. Edward Gleeson MAusIMM (CP) BEng (mining). Dr Fowler and Mr. Gleeson have appropriate qualifications and sufficient relevant experience to qualify as Qualified Persons for the reporting of a Mineral Resource for the Three Brothers Vein of the Muguk Gold Mine.
