Endeavour Mining Drilling at Agbaou Demonstrates Potential for Pit Expansion

VANCOUVER, Sept. 6, 2012 /CNW/ - Endeavour Mining Corporation ("Endeavour") (TSX:EDV) (ASX:EVR) (OTCQX:EDVMF) today announces drill results from the ongoing near-mine exploration program on its Agbaou gold deposit in Côte d'Ivoire. Exploration success is indicating further upside beyond the current mineral resources and reserves. Agbaou mine construction remains on track to begin production in Q1 2014.

Project Construction

Endeavour recently announced receipt of the official decree from the government of Côte d'Ivoire granting its Ivorian subsidiary the Mining Permit for its 85%-owned Agbaou Gold Project.  There are no other permits required for construction and production at the Agbaou Gold Project. Long-lead items for Agbaou construction such as mills, transformers and electrical lines have already been ordered. More recently, ground clearing and crop compensation have begun in preparation for commencement of earthworks expected later this month.

Exploration Results

Exploration drilling has focused on delineating the targets identified during condemnation drilling and on extensions to the principal mineralized zones in the Main and South pit areas (News Releases dated August 3, 2011 and September 12, 2011). The intercepts are shallow; all assays are at depths of less than 100m with a majority of the intersections at depths of less than 60m.

Highlights of the exploration drilling program at Agbaou include (Table 1);

Gérard De Hert, VP Exploration, stated:

"We are pleased with the ongoing success of this drilling program, which is aimed at increasing the mine life at Agbaou prior to commencing production in early 2014. The results on the P2 and P9* targets support the interpretation of southern extensions from the mineralization in the Main and South pits while drilling around the West Pit and on the P5 and P6 targets has supported the extension of that deposit to the southwest and northeast. We are also testing the down dip potential below the current pit limits in several areas using core drilling."

*P9 results were reported in June 11, 2012 news release, including 6m of 2.02 g/t gold.

Resource Estimate

An updated resource estimation will be completed once the assays from the recent core drilling are available. Agbaou currently has a Measured and Indicated resource of 1.157 million ounces gold comprised of 6.262 million tonnes at 2.2 g/t (438,200 ounces gold) Measured and 8.708 million tonnes at 2.6 g/t (718,500 ounces gold) Indicated (at a 0.5 gram per tonne ("g/t") cut-off, SRK May 2012).  A further 1.473 million tonnes at 1.5 g/t (72,900 ounces gold) is in the Inferred category.

About Endeavour Mining Corporation

Endeavour is a gold producer delivering growth. Endeavour owns two gold mines producing approximately 200,000 ounces per year in Ghana and Burkina Faso that are generating significant operating cash flows to fund exploration and development growth. In addition to upside potential at its current operations, Endeavour's third gold mine, Agbaou in Côte d'Ivoire, has entered the construction phase for an additional 100,000 ounces per year starting in Q1 2014. Endeavour has a strong financial base from which to invest in long-term operational growth, exploration to replace and increase reserves, and funding for acquisitions.

On August 7, 2012, Endeavour announced a definitive agreement to acquire Avion Gold (TSX:AVR) to become one of the largest West African gold mining companies with three producing mines, a fourth mine currently in construction, and an attractive pipeline of exploration and resource development properties. The Avion transaction is expected to close in October 2012.

Endeavour Mining Corporation is listed on the TSX (symbol EDV) and ASX (symbol EVR), and also trades on the OTCQX (symbol EDVMF).
