George Town, Grand Cayman, September 19, 2011 - Endeavour Mining Corporation ("Endeavour" or the "Corporation") (TSX:EDV) is pleased to report positive results from the ongoing exploration at its Youga Gold Mine property located in Burkina Faso, West Africa.

Neil Woodyer, CEO commented "We are pleased with the exploration successes achieved at Youga. The new discoveries are close to the current pits and represent possible mine life additions. We look forward to more drill results in the coming months."

Zergor�

The Zergor� deposit is located 2.5 kilometres east of the Youga plant. Zergor� has a recently reported Inferred Mineral Resource of 2.304 million tonnes with an average grade of 1.29 g/t Au at a 0.5 g/t Au cutoff grade (News Release dated February 17, 2011).

Recent results from in-fill reverse-circulation ("RC") drilling have consistently demonstrated continuity of grades and widths and continue to improve the confidence, quality and interpretation of the mineralised zones within the deposit. A number of significant intersections were reported including; YZRC-110 with 30m at 2.4 g/t including 1m at 10.3 g/t and YZRC-169 with 10m at 5.9 g/t including 3m at 11.4 g/t (see Table 1).

*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.

Due to the close proximity of these new discoveries to the current pits and the possible significant potential impact on operations, the resource estimation of these zones has moved up in priority and the data is currently being prepared for delivery to the resource estimation team.

Exploration Campaign at Youga Mine and Youga Gold Belt in 2011

Endeavour'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 kilometres of the Youga Plant, Endeavour initially committed US$10 million to the exploration program in 2011. Based on recent positive results and additional targets, Endeavour has committed an additional US$2.6 million bringing the commitment to a total of 73,000 m of RC and core drilling as part of exploration and resource/reserve development.
