Toronto Stock Exchange: EDV
GEORGE TOWN, Grand Cayman, Aug. 3, 2011 /CNW/ - Endeavour Mining
Corporation ('Endeavour' or the 'Corporation') (TSX:EDV) today
announces positive exploration results on development projects in Côte
d'Ivoire and Burkina Faso, and operational results for the second
quarter of 2011.
-- Infill drilling program at the Agbaou feasibility-stage project
in Côte d'Ivoire resumed in June 2011. The results received to
date have consistently demonstrated continuity of grades and
widths and confirmed the quality and interpretation of the
mineralised zones within the deposit. Intersections include 24
metres at 10.66 g/t gold and 10 metres at 17.06 g/t gold.
-- In addition, significant new exploration results were obtained
from the Agbaou condemnation drilling campaign in areas which
were being conceptually considered for the location of the
tailings storage facility and the waste rock dump.
Intersections from the waste rock dump area included 4 metres
at 9.75 g/t gold and 6 metres at 3.58 g/t gold.
-- Positive technical evaluation work for the expansion of the
Youga Main and East pits and the 2010 NI 43-101 resource
estimate will be updated during the second half of 2011 to
include the encouraging exploration results on the periphery of
the current pits.
-- Exploration results from a resource delineation and expansion
program at the Ouaré deposit, located 40 kilometres northwest
of the Youga Mine in Burkina Faso, include intersections of 8.8
metres at 3.83 g/t gold and 6.4 metres at 2.55 g/t gold which
confirm earlier interpretations and demonstrate continuity of
the Ouaré Main Zone.
-- Metallurgical testwork is being initiated at Ouaré in
preparation for scoping studies to evaluate whether the deposit
will be fed to the Youga mill or potentially be a heap leach
operation.
During Q2 2011, the Youga Mine in Burkina Faso produced 21,575 ounces of
gold. Based on actual production results of 41,631 ounces for the
first half of 2011 and the budgeted plan for the remainder of 2011, the
Corporation anticipates achieving its full year guidance of
approximately 84,000 ounces. Endeavour is scheduled to release its full
Q2 2011 results on Wednesday, August 10, 2011.
Côte d'Ivoire
Agbaou Project Development
Endeavour is pleased to report that the 20,000 metre drilling program at
the Agbaou feasibility-stage project in Côte d'Ivoire resumed in late
June 2011.
The current measured and indicated mineral resource at a 0.5 g/t cut-off
is 16.6 million tonnes at 1.9 g/t gold containing 1,015,000 ounces plus
an inferred mineral resource of 5.1 million tonnes at 1.7 g/t gold
containing 272,000 ounces(1). A portion of the drilling program is designed to upgrade mineral
resource classifications and to increase the size of the deposit. The
results for the initial 45 RC infill holes (3,104 metres) have been
successful at confirming the continuity of grade and widths of
mineralization and the highlights are provided in Table 1.
The area north east of the Agbaou West Deposit (Figure 1: http://files.newswire.ca/910/Figure_1.pdf), and on the periphery of the proposed waste rock dump, was
investigated by RC drilling which returned results including 4 metres
at 9.75 g/t gold and 6 metres at 3.58 g/t gold suggesting possible
extensions of the west pit orebody and/or the possibility of a new
orebody. On the south end of the waste dump are several intersections
that may represent extensions of the Main Zone mineralization to the
south west.
Further to the north, on the west side of the conceptually planned
tailings facility, two holes at the end of a fence of holes returned
values of 1.18 g/t gold and 1.89 g/t gold over 6 metres and 2 metres
respectively. The relationship of this area to other mineralized zones
is not known at this time and follow up exploration work is planned to
test this possibility of additional mineralization.
These holes are being drilled on sections nominally spaced 300 metres
apart with hole spacing 25 metres apart.
An additional 44 holes were completed without significant results in
areas of planned infrastructure and facilities.
Neil Woodyer, Chief Executive Officer, stated 'I am pleased to report on
the positive infill drilling results received to date following the
resumption of work at our feasibility stage project in Côte d'Ivoire
and I am excited by the new mineralisation discovered at the project
site during condemnation drilling. In addition to engineering studies
to support a mine construction decision during Q1 2012, we are now
planning a drilling program to follow-up on this unexpected
mineralization.'
Photos of current drilling activity have recently been posted on the
Corporation's website. Work continues on engineering studies which
includes a study of power supply options. A mine construction decision
for Agbaou is anticipated for Q1 2012 with gold production scheduled to
commence in late 2013.
Burkina Faso
Youga Mine Lease and Youga Belt Exploration Permits
Mining on Endeavour's Youga Mine Exploitation Lease commenced in 2008
and by the end of 2010 a total of 193,000 ounces of gold have been
recovered. The NI 43-101 compliant mineral resources at a 0.5 g/t
cut-off were estimated at 868,000 ounces (measured and indicated) plus
276,000 ounces (inferred) and the mineral resources contained 362,000
ounces of mineral reserves(2).
In 2011 Endeavour embarked on a major exploration program focused on
increasing the mineral reserves and resources for the Youga mine in
order to extend mine life and increase asset value. The principal drill
target areas being:
-- Peripheral extensions to the currently operated Main and East
pits.
-- The Zergoré, Nanga, Tail, LeDuc and A2NE satellite deposits on
the Youga mine lease.
-- Targets on the Bitou exploration permit, located 40 kilometres
north east of the Youga processing plant, which hosts a number
of targets including the 323,000 ounces Inferred mineral
resource with a 0.5 g/t cut-off at Ouaré(3).
See Figure 2: http://files.newswire.ca/910/Figure_2.pdf for locations of deposits on the Youga mine lease and Figure 3: http://files.newswire.ca/910/Figure_3.pdf for the location of the Bitou permits and Ouaré deposit.
In the first half of the year a total of 26,545.5 metres of RC and
diamond core drilling has been completed on these targets with
encouraging results in all three areas from the assays returned to
date.
Youga Mine Lease
Main / East Pit Pushback and Exploration
During the first half of 2011, and subsequent to the release of the
December 2010 NI 43-101 Technical Report (issued March 2011), the open
pit designs were re-evaluated based on updated cost and gold price
factors. The re-evaluation demonstrated that the re-optimised pits
would increase in size in terms of depth, daylight footprint and
contained mineral resources. Subsequent to this re-optimisation and
prior to making a decision to proceed with the expansion, work has
focused on evaluating the various technical, timing and practical
mining requirements of the plan. The principal aspects being assessed
are the availability of mining capacity and the slope angles applicable
to the revised pit shell. Work on these areas is currently being
finalized.
In parallel to the engineering studies, considerable exploration
drilling has been undertaken on the periphery of the deposits in the
East Wall of the Main Pit (Triple A Zone), North Wall of the East Pit,
the Gap zone between the pits and to the east of the East Pit. This
exploration work has returned interesting mineralisation intercepts
from all four areas and the mineral resource model is in the process of
being updated to include these results. Infill and extension RC and
diamond core drilling and updating of the mineral resource models will
continue throughout the remainder of 2011 to follow up on the results
to date in all four areas in order to define the full potential of
these mineralized zones and the extent to which this will add further
value to the economics of the planned pushbacks. Table 3 provides a
selective summary of recent drill results from the pit areas and also
related intercepts in these same areas obtained from previous drilling.
The current drill program has identified additional mineralization in
the previously announced Triple A zone on the East wall of the Main pit
where a diamond drill hole reported 37m at 2.0g/t including 4m at 6.3g/t (February 17, 2011 Press Release). The follow‐up
drilling reported intersections in five of the holes including; 8m at
6.4g/t including 1.8m at 15.0g/t, and 3m at 18.8g/t including 1m at 37.8g/t (February 17, 2011 Press Release). One hole has
now reported 7m at 1.66g/t including 1m at 5.16g/t and additional drilling is underway to test this area immediately
adjacent to the current pit limits with 13 holes.
Previously reported results from the North wall of the East pit include
4m at 2.1g/t, 7m at 2.2g/t including 2m at 5.0g/t, 4m at 4.7g/t
including 1m at 6.2g/t (at the end of the hole) and 26m at 1.9/t including 2m at 4.3g/t (May 30, 2011 Press Release). Results from
mineralization in the vicinity of the Main and East pits include 11
metres at 1.61 g/t gold and 10 metres at 1.48 g/t gold. However based
on the new interpretation several of these new holes were not drilled
deep enough to test the projected mineralization and several RC holes
have subsequently been deepened with core, these results are pending.
Endeavour's on-going exploration focus is the addition of mineral
resources and reserves at Youga to support further technical evaluation
work on the Main and East pits pushbacks.
Mining Lease Satellite Deposits
Drilling continues on the mine exploitation lease and within 3
kilometres of the Youga plant on depth and strike extensions at the
A2NE, Zergoré, Nanga and Tail deposits, which collectively contain
159,000 ounces indicated and 165,000 ounces inferred at a 0.5 g/t
cut-off, NI 43-101 compliant, gold resources(2). In the first half of 2011, preliminary evaluation of the satellite
deposits, based on the currently declared resources, was undertaken and
indicated reasonable potential for these deposits to be ultimately
incorporated into the life of mine plan production plan.
Drilling highlights from the satellite deposits reported in previous
news releases are summarized in Table 4. New drill results from these
areas are currently being received and evaluated while additional
drilling is planned.
Youga Belt Exploration - Bitou Concession - Ouaré Deposit
The Ouaré project is located on the Bitou permit 40 kilometres northwest
of the Youga plant (see Figure 3: http://files.newswire.ca/910/Figure_3.pdf and Figure 4: http://files.newswire.ca/910/Figure_4.pdf). Figure 4 shows the drilling performed to date on Ouaré Main and
Ouaré West.
At Ouaré, the exploration camp was constructed during Q1 2011 and
drilling commenced in Q2 2011. The first phase of the drill program is
well underway and largely consists of in-fill drilling with both RC and
core-drilling on the Ouaré Main and Ouaré East zones with the objective
of improving the geological model and upgrading the resource
classification. The second phase will explore along strike and to
depth to test for additional resources.
Results of the first 4,376 metres (42 RC holes) of the planned 25,000
metre drill program provided the highlights in Table 5. As of July 8,
2011 106 RC holes (11,737 Meters) and 14 core holes (1,699.5 meters)
have been completed.
Initial exploration results include intersections of 8.8 metres at 3.83
g/t gold and 6.4 metres at 2.55 g/t gold and numerous intersections
across of variable grade and width ranges confirming the presence of
significant gold mineralisation within the first 100 metres depth of
the deposit. Many results are still pending but highlights from the
initial drill-holes confirm continuity of the Main Zone and are
included in Table 5.
The previously reported inferred mineral resource at a 0.5 g/t cut-off
at Ouaré was 4.738 Mt at 2.1 g/t containing 323,000 ounces gold(3). The deposit is over two kilometres long and had been nominally tested
on 50 metre spaced sections to a maximum depth of 100 metres. The
current program is designed to reduce the drill hole spacing to 25 by
20 metres and to extend the resources to at least 150 metres depth on
selected sections.
Samples for metallurgical testwork will be collected from core holes on
the Ouaré Main, West and East zones. The testwork will be part of
engineering studies that will examine the potential to exploit these
resources through either hauling to the existing Youga plant or
processing the ores as a heap leach operation at the Ouaré site.
Youga & Ouaré Exploration Campaign Progress
The 2011 exploration campaign was planned to drill over 50,000 metres on
17 targets. First pass drilling to date is complete on ten of these
targets and continues on five of the targets. There are four rigs
currently active and the program has been revised to 63,000 metres.
Results are pending for drilling on nine zones.
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.
Endeavour contracted Fugro NPA to complete a compilation of satellite,
geophysical and geochemical data to identify principal structural
features relative to the mineralized zones. The Corporation also
contracted SRK to commence a structural study including all property
datasets and also mapping and core review. The first phases of these
studies are complete and are being integrated for exploration
targeting. SRK will be contracted to conduct additional work as the
exploration program progresses. The majority of the mineralized zones
on the Youga mine permit are within Tarkwa sediments. Endeavour holds
two exploration permits to the southwest of Youga and these cover two
basins that were highlighted by the NPA Fugro study. These additional
Tarkwa inliers are at Bourgre and Zerbogo. A geophysical survey has
been contracted for after the rainy season and geochemical coverage
will be expanded to cover these prospective areas in addition to
planned soil geochemistry surveys.
Burkina North Project Exploration
Endeavour is preparing to commence the first phase of an exploration
program on Burkina North Project located in central Burkina Faso, 140
kilometres north of Ouagadougou. The project area is comprised of two,
contiguous permits (Boulounga and Minima) strategically located
adjacent to and north of High River Gold's Bissa Hill deposit (2.65 Moz
Measured and Indicated, February 2011, Newall) and Goldrush's Ronguen
deposit (0.24 Moz Inferred Resource, May 2008, Nimoh, Wahl and
Couture). The program includes completion of the regional soil
geochemistry over the Minima Permit and auger drill testing the
north-south VTEM anomaly on the Boulounga Permit.
Neil Woodyer, Chief Executive Officer, commented 'In Burkina Faso,
steady and encouraging progress has been made on near mine exploration
and technical evaluation work to extend the ore reserve base on the
Youga mine exploitation permit and on the exploration program at the
Ouaré deposit located on the Bitou concession 40 kilometres north of
the Youga mine plant.'
