NEWS RELEASE
Monday, April 30 2012 1STRONG DRILLING
RESULTS FROM
ENDEAVOUR MINING’S
YOUGA GOLD MINE
Monaco, April 30, 2012 – Endeavour Mining
Corporation (“Endeavour”) (TSX:EDV, ASX:EVR,
OTCQX:EDVMF) is pleased to report positive results
from the ongoing exploration programs along the
Brassiere Trend at its Youga Gold Mine in Burkina
Faso. Drill intercepts from the southern extension of
the Zergoré deposit on the Brassiere Trend included
YZRC
‐201 with 42 metres (m) of 3.4 grams per tonne
(g/t) gold which included 1 m of 14.5 g/t gold and 4 m
of 6.3 g/t gold. These results reinforce Endeavour’s
exploration efforts to further extend the mine life at
the Youga Gold Mine.
The Brasserie Trend includes the La Forge prospect on the
southwestern end, the 900 m long Zergoré deposit and the Castel, Beaufort and Flag prospects at the northern end (Figure 1). The prospects are along the eastern edge of the Youga Exploitation Permit and within 4 kilometres of the Youga plant.
Additional drill results from other targets along the trend included,
YCRC-001 with 26 m of 2.8 g/t on the Castel target, YBRC‐014 with 5 m of 2.1 g/t gold and included 1 m of 5.4 g/t gold at the Beaufort target and YLFRC‐006 with 7 m of 1.9 g/t gold, including 1 m of 3.0 g/t gold at the La Forge target. Additional highlights of drilling on each of these targets are provided in Table 1.
The Zergoré portion of the trend is interpreted to be a shallowly south-plunging anticline in strongly foliated greywacke and metavolcanics. The western limb of the Zergoré zone follows the contact between Tarkwaian arkosic sandstone and underlying greywacke. The eastern branch of the anticline becomes the Brasserie Trend and continues to the northeast for 2 km to connect with the Castel, Beaufort and Flag targets.

A resource estimate was reported for Zergoré in 2011 (Technical Report and Update of Mineral Resources and Mineral Reserves for the Youga Gold Mine, Burkina Faso, West Africa, effective December 31, 2010 and dated March 15, 2011, prepared by A. de Freitas and K. Woodman) and the deposit was added to the mine plan at the end of the year. The Proven and Probable reserves from Zergoré are 1.2 million tonnes at 1.5 g/t Au containing 58,000 ounces (A. de Freitas, 2012). Measured and Indicated resources at a 0.5 g/t cutoff, inclusive of reserves, are 2.9 million tonnes at 1.2 g/t Au containing 108,000 ounces (Woodman, 2012). Additional information regarding the Zergoré reserves and resources is provided in Table 2. Mineralization at Zergoré is along foliation and axial planar features. Gold soil geochemistry as well as airborne geophysics clearly correspond to Zergoré and support the interpretations of the extensions. The current drilling program continued to work on strike extensions to the south and the northwest and northeast.
Drill intercepts at Castel and Beaufort were within the westernmost fence of holes on both targets. The hole orientations are being adjusted for the follow up drilling.
The 2012 Youga exploration campaign includes a total of 51,000 m of drilling comprised of 10,500 m core drilling and 40,500 m reverse circulation drilling planned for 19 targets within the mine permit area with a budget of approximately US$7.5 million.
