Near-Mine Exploration Programs Yield Strong Results for Endeavour Mining
NEWS–MONACO – Endeavour Mining Corporation (“Endeavour” or the “Corporation”) (TSX:EDV, ASX:EVR) is pleased to report the results from the successful 2011 exploration programs and provide an overview of the 2012 work plans for the Nzema gold mine in Ghana and the Youga gold mine in Burkina Faso. Total attributable measured and indicated mineral resources have increased to 3.8 million gold ounces plus 1.4 million gold ounces inferred as of December 31, 2011 at a 0.5 g/t cut-off (see Table 1 at the end of this news release). Highlights include:
Youga gold mine, Burkina Faso
49% increase in proven and probable reserves (a gain of 179,000 ounces; net of 2011 depletion) and extension of mine life to 7.3 years (see Table 2 at end of this news release)
Addition of 172,000 ounces of measured and indicated mineral resources (net of 2011 depletion, at a 0.5 g/t cut-off) from the Main and East hanging wall mineralization and the satellite deposits
Nzema gold mine, Ghana
Addition of 65,000 ounces of measured and indicated mineral resources (net of 2011 depletion, at a 0.5 g/t cut-off), plus a 40% increase of inferred mineral resources of 186,000 ounces at a 0.5 g/t cut-off
- Updated Nzema reserves are currently being prepared for reporting in the next few weeks
2012 Exploration Budget
Exploration budget of US$30 million for 2012 to continue resource delineation, test deposit extensions and exploration of new targets including $7.5 million allotted to Youga and $8.1 million to Nzema mine permits. The 2012 exploration budget includes +200,000 metres of drilling.
Over 60% of the combined 2011 exploration expenditure of $23 million was dedicated to delineating resources and increasing reserves at the Youga and Nzema mines with a combined total of 82,252 metres of drilling. An exploration summary with a list of previously unreported drill hole intercepts and exploration activities in the fourth quarter of 2011 is provided on the Endeavour Mining website (http://www.endeavourmining.com/i/pdf/2011-12-31_ES.pdf) and should be read in conjunction with this news release.
Neil Woodyer, CEO, stated: “I am very pleased with the results of the 2011 exploration programs. With both Nzema and Youga operating in steady-state mode, our primary exploration focus was to extend mine life and at Youga we extended mine life to 7.3 years by increasing reserves by 49% (net of 2011 depletion). At Nzema, where existing reserves support a 10 year mine life, the exploration programs focused on oxides and sulphides along the Salman trend. I expect the on-trend oxides could enhance the short to medium term production scheduling while the sulphides provide us with a large-scale opportunity. In addition, we are now in a position to extend our exploration efforts to our early stage projects in Côte d’Ivoire, Mali and Liberia.”
Youga 2012 Exploration Program
The 2012 Youga program includes 10,500 metres core drilling and 40,500 metres reverse circulation (RC) drilling within the mine permit area and will test:
depth extent of the Main deposit to examine the possibility for pit expansion or underground potential
the East deposit on strike, exploring a possible fault offset area, and also to test below the planned pushback prior to commencement of mining
- strike extensions of the A2NE, Zergoré, NTV deposits to add resources
several prospects (Laforge, Castel, Beaufort) on the 3 km long Brasserie Trend which extends north and south from the Zergoré deposit
- the Leduc deposit which will be examined for potential to add to resources this year.
In addition, several new exploration targets have been identified for prospecting and drilling, following completion of a comprehensive structural synthesis based on field examinations and the existing airborne magnetic and radiometric survey of the Youga area.
The majority of mineralization at Youga is hosted within Tarkwa sediments however the A2NE and Zergoré deposits have demonstrated that similar opportunities are present in the surrounding Birimian greenstone belt. Soil geochemistry, ground geophysics, and RC drilling is planned on Tarkwa and Birimian units within the surrounding Zerbogo and Songo permits.
Nzema 2012 Exploration Program
The 2012 Nzema exploration program includes:
- delineating and exploring the oxides in Salman and Anwia
- drilling of the Salman trend sulphides
drilling on Aliva, Bokrobo, Nfutu, Avrebo to delineate additional resources and improve classification of inferred resources
- exploration drilling on Tumentu, Akropon, Bernard and Hotopo areas.
The program includes 8,200 metres core drilling and 27,900 metres RC drilling mostly on the deposits in the immediate mine area plus 17,800 metres reverse air blast (RAB) and air core drilling plus auger, trench, soil sampling programs to develop new oxide targets.
In 2011, a conceptual study including initial metallurgical testwork for the Salman sulphides was received and forms the basis to advance this significant opportunity towards a preliminary economic assessment. The 2012 Salman sulphide work program will include resource delineation, further metallurgical testwork, and associated engineering studies.

About Endeavour Mining Corporation
Endeavour is a growth focused West African gold production and exploration company led by an accomplished management team. Endeavour is currently producing gold at a rate of 180,000 ounces per year from two operating mines (Nzema in Ghana and Youga in Burkina Faso). With a near-term mine construction decision (Agbaou in Côte d’Ivoire) and an extensive 2012 exploration program underway, Endeavour’s goal is to produce approximately 250,000 ounces of gold per year from the end of 2013 from existing properties. Endeavour also has an acquisition growth strategy focused on West Africa and is targeting the acquisition of additional gold production before the end of 2013.
Endeavour Mining Corporation is listed on the TSX (symbol EDV) and ASX (symbol EVR).
