ENDEAVOUR MINING REPORTS POSITIVE EXPLORATION RESULTS AT YOUGA INCLUDING 26m at 1.9g/t and 12m at 2.8g/t09:00 EDT Monday, May 30, 2011Toronto Stock Exchange: EDV All figures are in US dollars, unless otherwise indicatedGEORGE TOWN, Grand Cayman, May 30, 2011 /CNW/ - Endeavour Mining Corporation ("Endeavour")(TSX:EDV) is pleased to report positive results from the ongoing exploration at its Youga Gold Mine located in Burkina Faso, West Africa.Click on link below for map of Youga Mine and Exploration Targetshttp://files.newswire.ca/910/Youga.pdfParallel Mineralization to the A2 East ZoneA drilling campaign was initiated on the hanging-wall side of the A2 East Zone to explore for parallel mineralized zones following the previously reported positive results from the Triple 'A' Zone (News Release dated February 17, 2011) which is parallel and located to the east of the A2 Main Zone.  The Triple 'A' Zone is outside of the current pit limit and engineering studies are underway to examine the potential impact of this mineralization on pit expansions.  Drilling for similar parallel structures along the north side of the A2 East Zone and also in the gap area between the A2 Main and East pits has intersected additional mineralization. Results from recently completed RC drilling reported a number of significant intersections including; RC-11-286 with 4m @ 2.1g/t, RC-11-288 with 7m @ 2.2g/t including 2m @ 5.0g/t, 4m @ 4.7g/t including 1m @ 6.2g/t (at the end of the hole) and RC-11-289 with 26m @ 1.9/t including 2m @ 4.3g/t (see Table 1).Table 1 Hanging-Wall to the A2 East Zone 2011 RC Drilling HighlightsHole IDFromToLengthAu Grade (m)(m)(m)(g/t)RC-11-280424423.1RC-11-283404991.2including474923.4RC-11-2851424101.1RC-11-286858942.1including858613.8RC-11-287515431.2RC-11-288475141.8including474814.6and535741.0and596672.2including596125.0and697561.1and96*10044.7including99*10016.2RC-11-2896389261.9including808224.3*denotes end of hole.**All intervals are reported as down-hole lengths and are not corrected to true widths for the mineralized intervals. Additional work is required to determine true widths.These results represent mineralization associated with previously unrecognized structures in the hanging-wall of the A2 East deposit. Additional drilling has been completed with results pending.  More holes are planned on parallel sections and to deepen some of the existing holes to further test the extents of these zones.ZergoréThe Zergoré deposit is located 2.5 kilometres east of the Youga plant and has a recently reported Inferred Mineral Resource of 2.304 million tonnes with an average grade of 1.29 g/t Auat a 0.5 g/t Au cutoff grade (News Release dated February 17, 2011).  A follow-up diamond and RC drilling campaign was initiated on the extensions and also in gaps in the mineral resource.Recent results from in-fill diamond drilling have confirmed the geological model and reported a number of significant intersections including; YZ-11-29 with 12m @ 2.8g/t including 1m @ 28.2g/t and YZ-11-32 with 21m @ 1.6g/t including 0.7m @ 9.2g/t(see Table 2).Table 2 Zergoré 2011 Diamond Drilling HighlightsHole IDFromToLengthTrue WidthAu Grade (m)(m)(m)(m)(g/t)YZ-11-271001011134.0YZ-11-291.115.814.7122.8including4.15.11128.2YZ-11-3185.495.710.381.7including88.489.4119.9YZ-11-3276.1102.426.3211.6including99.7100.40.70.79.2YZ-11-336578.513.5112.3including73.674.50.90.99.2YZ-11-3437.144.1762.7including38.239.2116.1YZ-11-3559.875.415.6122.0including66.368.3225.1YZ-11-360.211.511.392.0including8.510.5227.3YZ-11-4524.528.053.5533.8and30.8531.70.85118.2YZ-11-462329.86.852.0including2526.11.117.3and60.97413.1101.9including7173223.9Diamond drill holes for samples for metallurgical testwork are underway on the Zergore, A2NE, Nanga and Tail zones.  The testwork will be part of ongoing engineering studies on advancing these mineral resources towards mineral reserves.Exploration Campaign ProgressThe 2011 exploration campaign was planned to drill test a total of 17 targets and drilling to date is well underway on nine of these targets.  In addition five new targets have been identified during prospecting, mapping and review of geochemical surveys with exploration programs to be developed to test these targets in 2011.Neil Woodyer, Chief Executive Officer commented "We are pleased with the results to date and look forward to additional positive results from the exploration program and the work to establish additional mineral resources over the next few months."Exploration Campaign at Youga Mine and Youga Gold Belt in 2011Endeavour's Youga Gold Mine, which has been in production since 2008, produced 82,400 ounces of gold in 2010 and is targeting production of 84,000 ounces of gold in 2011. Endeavour's on-going exploration focus is the addition of mineral reserves at Youga. Building on the success of the 2010 Youga exploration campaign, which identified several new resource targets within 3.5 kilometres of the Youga Plant, Endeavour has committed $10 million to the exploration program in 2011.Qualified PersonK.
