Abidjan, November
7
, 2016
- Endeavour Mining Corporation (TSX:EDV)(OTCQX:EDVMF) is pleased to announce a
maiden Mineral Resource estimate for its recent Bakatouo and Colline Sud
discoveries at its Ity Gold Mine in Cote d'Ivoire. It also announces the
identification of several new high-priority near-mill exploration targets
following the completion of its Auger drilling program.

The Bakatouo and Colline Sud deposits, both located within 2.5km from the
current processing plant, are characterised by their high-grade and
close-to-surface mineralization and remain open in various directions.
Moreover, a large portion of the resource is amenable to the heap leach
process with oxide and fresh mineralization content making up 42% of the
total Indicated resource ounces. This suggests the potential to both extend
the existing heap leach operation and improve the economics of the future
Carbon-in-Leach ("CIL") project, for which a feasibility study is expected
shortly.

The Bakatouo and Colline Sud resources have been estimated based on the drill
results published on September 13 and October 14, 2016, respectively.

| Total 5,400 2.97 515 1,234 2.73 108 |
-------------------------------------------------------------------------------

The mineral resource estimate of the Bakatouo and Colline Sud deposits are
reported in accordance with National Instrument 43-101 and has been estimated
using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM)
"Estimation of Mineral Resources and Mineral Reserves Best Practice
Guidelines". The mineral resource estimate is classified as "Indicated" and
"Inferred" as defined by the CIM. More details provided in Appendix 1.

Sébastien de Montessus, President&CEO, stated:"We are very pleased with these
results and resource estimates as they
demonstrate the significant upside potential that exists in and around Ity.
They reinforce our belief that Ity can become
another flagship asset
. We will soon be publishing the feasibility study for the proposed CIL
project and will work to update this in early 2017 to include these new
resources. As part of this, we will examine the trade-off opportunity of
operating both the existing heap leach operation and CIL in parallel for the
first few years."

Patrick Bouisset, Executive Vice-President Exploration and Growth of
Endeavour, commented:"Beyond the recently announced discoveries and
high-grade resource increase,
we are very excited about the prospectivity of the Greater Ity Area. The
results of our Auger drilling program coupled with our gold in soil and
structural analysis indicate that the overall potential of the area extends
well beyond our present resource footprint.

We
look forward to continuing to expand our ongoing exploration program to
further explore the newly identified near-mine targets and along the wider 80
kilometer trend, for which a high resolution Airborne geophysical survey is
expected to be initiated before year-end."

About the Auger drilling program and New Identified Targets

A regional 2,150 holes Auger drilling program, totalling 26,855 meters, has
recently been completed within a 5km area of the current mining complex, on
both the 55%-owned Ity mine area and the 100%-owned adjacent exploration
tenements.

Auger results indicate that very strong anomalous gold values (>1,000 ppb)
occur within the saprolite at numerous locations within the area covered by
the program, allowing for the definition of large and highly anomalous
clusters and the generation of several new near-mine high priority
exploration targets.

The most significant near-mine targets identified are:

* Bakatouo Northeast area: Auger results clearly suggest a 1km northeast
trending anomaly located immediately to the northeast of the new Bakatouo
discovery, with best values>7,000ppb in the saprolite.
* Vavoua area : New 1.5km northeast trending anomaly with best
values>1,400ppb in the saprolite.
* Morgan/Yacetouo area : Large and significant 3km long and northeast
trending anomaly with best values>2,450ppb in the saprolite.
* Le Plaque area (PR 558) : Significant 2km long N20° trending anomaly with
best values>5,000ppb in the saprolite.
* Daapleu Southwest area : Large gold anomaly in saprolite that covers over
4km², with best values>2,200ppb.

Drilling grid N135° was designed to be orthogonal to the regional geological
structural trends. A total of 9,640 samples were collected at 200 x 50 meters
and 400 x 50 meters grid spacing.

The defined Auger clusters may correspond and validate previously identified
gold in soil anomalies (such as in Colline Sud or Daapleu) or allow for the
definition of new prospective areas (such as Bakatouo NE or Daapleu SW),
where no gold in soil anomalies were previously detected due to a probable
alluviums cover associated with Cavally river overflows.

All the holes penetrated the alluvial cover and were terminated at least 2
meters within the mineralized saprolite. A high number of samples taken
within the lateritic to mottled zone section above the saprolite also
returned some very high grades (up to 10,000 ppb over several meters).
Although these samples may not represent the nature of the underlying geology
and mineralization, they indicate gold occurrences in the area of the newly
defined targets. This reinforces our view that these targets are highly
prospective.

Next Steps

* Exploration has resumed on Colline Sud and is expected to continue in
H1-2017
* Exploration is expected to soon resume on Bakatouo and on the newly defined
exploration targets and continue in H1-2017
* Further insights on the medium-term exploration will be detailed in the
upcoming Exploration Strategic Review for both the near-mine and Greater
Ity Areas.
* High resolution Airborne geophysical survey (Mag/Spectro/VTEM) expected to
be initiated before year-end on the 80km-long Greater Ity Area
* Feasibility Study for Ity CIL Project expected to be published later this
week, which will be updated in H1-2017 to include the Bakatouo and Colline
Sud discoveries

About the Mineral Resource

The effective date of this resource estimate is June 27, 2016. The mineral
resource is reported at a 0.50 g/t gold cut-off grade within Whittle
optimised pit shells based the economic parameters described in Table 2
below:

Table 2: Whittle Pit Shell Parameters

----------------------------------------------------
| Parameter |
| Pit Slope Angle 40o |
| Gold Price US$1,500/oz |
| Mining Cost $3.5/t |
| Mining Recovery 95% |
| Mining Dilution 30% |
| Processing Cost $30/t |
| Colline Sud Recovery Rate 90% |
| Bakatouo Recovery Rate Varies between 70-90% |
----------------------------------------------------

Preliminary metallurgical studies done on the Bakatouo and Colline Sud
deposits indicate that the gold recoveries of the mineralized material are
similar to the other deposits at the Ity Gold Mine.

Bakatouo Resource Modeling

The Bakatouo gold mineralization is carried in various facies such as oxide
and reduced superficial clays, granodiorite, marbles, and endo and exoskarn
facies located at the contact between intrusives and sediments. This
mineralization is characterised by high-grade areas, especially where
karstification processes concentrated the initial gold mineralization into a
much smaller rock volume.

The Bakatouo geological model was developed in Leapfrog 3D modeling software
using available geology information from 165 diamond drill holes totaling
20,417 meter completed between 2014 and 2016. The geological model and assay
data guided the mineralisation model. A total of 20 mineralized domains were
interpreted and modeled into 3D wireframes within Geovia Surpac modeling
software. The mineralized zones have an average strike of 45oazimuth dipping
50oNW. The drill holes gold assays were composited to one meter intervals
within the mineralized wireframes and capped at 50 g/t Au. Spatial analysis
of the gold mineralization using variograms indicated a good continuity of
the grades along strike and down dip of the mineralised zones.

Gold grades were interpolated using ordinary kriging constrained by the
mineralized domains. Density values of the oxidized material vary from 1.3 to
1.5 based on weathering material type while the fresh rocks density values
vary from 2.7 to 2.9 based on rocktypes. The mineral resource was modelled
using a 3D block model built in Geovia Surpac. Measures were conducted to
validate the accuracy of the estimate, including comparing results from the
kriging estimate to inverse distance and nearest ne...
