Positive Drilling Results from Endeavour's Youga Gold Mine

Positive Drilling Results from Endeavour's Youga Gold Mine09:00 EDT Monday, May 28, 2012VANCOUVER, May 28, 2012 /CNW/ - Endeavour Mining Corporation ("Endeavour") (TSX: EDV) (ASX: EVR) (OTCQX: EDVMF) is pleased to report positive results from drilling beneath the Main Pit at the Youga Gold Mine.  Drill intercepts included A2-11-220 with 52.5 metres (m) of 2.1 grams per tonne (g/t) gold which included 2.6 m of 5.2 g/t gold. The drilling beneath the main pit at the mine has shown a continuation of the A2 Main deposit and highlighted the potential for further pit expansion.__________________________________________________________________________________________________________________________________________Neil Woodyer, CEO, stated"Building on the success of our 2011 exploration campaign at Youga, we committed additional funding to accelerate our exploration and resource delineation campaign as part of our overall US$34 million exploration program for 2012.  These latest drilling results demonstrate we are now reaping the benefits of this commitment to exploration." __________________________________________________________________________________________________________________________________________A series of six core holes totalling 2,636.4 m were completed and assayed in late 2011 and 2012 (Figures 1, 2 and 3) based on results of the Youga A2Main open pit design update.  The expanded pit design used a higher gold price ($1200/oz) and incorporated drilling from the flanks of the A2Main and A2East deposits.  The work underscored the need for additional drilling to fully test the deeper portion of A2Main deposit.  Highlights are included in Table 1.Based on these positive results 10 additional holes are planned to test the mineralization at and below the ultimate pit limits. The program is a combination of reverse circulation (RC), core and deepening of existing holes and consists of a total of 3,700m of drilling.Pit mapping and structural studies have shown that the C1 and C2 faults have offset portions of the A2Main deposit and control the flattening of the mineralization on the north end (Figure 1).  A wedge of mineralization between the C1 and C2 faults intersected by hole A2-11-220 will be delineated in the next round of drilling (Figure 2).  Drilling in 2011 and 2012 has also demonstrated that mineralization does occur on the northeast side of the C2 fault but the amount of offset is not confirmed however exploration will continue to test both sides of the fault.Table 1: A2 Main Drilling Highlights (Sorted by Northing of Intersection)SectionHoleFromToLengthTrue WidthAu GradeFinal DepthNumberID(m)(m)(m)(m)(g/t)(m)7650 NA2-11-22020721143.44.3500 and3063676152.52.1  including35435732.65.2  including35936454.34.6 7700 NA2-11-2351451631813.13.3500.1 including14515164.45.6  and205215107.31.3  including21321410.73.9  and2893041511.01.1  and381391107.31.0  and39640485.82.3  including40240310.77.7 7775 NA2-11-23151.555.13.62.43.8534.4 including51.552.510.76.5  including54.255.10.90.66.7  and7278.96.94.61.7  including7475.51.51.03.3  and367.53768.55.71.2  including374.83761.20.83.3  and454497.243.228.90.8  including477490138.71.3  and505517.812.88.61.2 7800 NA2-11-226446.6468.62218.91.0500.2 including447.6449.621.72.5 7850 NA2-11-236271.6278.675.13.4361.77850 NA2-11-228199.5209.510102.3240 including206.5207.5115.6 On Section 7650N hole A2-11-220 was targeted 100 m below previous intercepts of the A2Main deposit but hit mineralization shallower and further east than anticipated because the mineralization appears to have been offset (right lateral) by the C1 fault (Figure 2).  Given the position of the hole relative to the C1 fault it is concluded that this may be an offset wedge of the A2Main deposit caught between the C1 and C2 faults.  This opens up an area for additional mineralization but with limited strike extent.On Sections 7700N, 7775N and 7800N drill holes A2-11-235, 231, and 226 intersected the A2Main deposit at depths that are 75 to 100 m deeper than previous intercepts on these sections.  Hole A2-11-231 has the deepest intercept of A2Main to date at -200 RL, which is 425m below original surface and 260 m below the final pit depth.  A2-11-226 and A2-11-231 end in mineralization and may have stopped within the A2Main deposit.On Section 7850N, at the north end of the A2Main deposit, drill holes A2-11-236 and A2-11-228 were testing an area that had not previously been drilled.  Both holes intersected the targets, with A2-11-236 returning 5.1 m (true width) at 3.4 g/t and A2-11-228 intersected 10 m at 2.3 g/t on a shallowly northeast dipping portion of the A2Main deposit.Figure 1: A2 Main Pit Drill Plan on Satellite Imageryhttp://files.newswire.ca/910/Figure_1.pdfFigure 2: A2 Main Cross Section 7650N, Looking Northhttp://files.newswire.ca/910/Figure_2.pdfFigure 3: A2 Main Cross Section 7700N, Looking Northhttp://files.newswire.ca/910/Figure_3.pdfQualified PersonsK.
