EAVOUR MAKES MAJOR GREENFIELD DISCOVERY IN CÔTE D'IVOIRE WITH
MAIDEN 1.1MOZ INDICATED AND 1.9MOZ INFERRED RESOURCE
TANDA-IGUELA HIGHLIGHTS
-- Tanda-Iguela property in Côte d'Ivoire has the
potential to be another flagship asset for Endeavour
-- Major maiden resource has been outlined in under 15
months on the Assafou target:
-- Indicated resource of 14.9Mt at 2.33 g/t for
1.1Moz; Inferred resource of 32.9Mt at 1.80

Assafou as its Indicated resource only covers
20% of the 3 km long identified mineralised
system which is open along strike and at depth
-- Assafou's structural geological trend is
highly prospective as it extends over a 15 km
long stretch with several identified
high-quality gold-in-soil anomalies
-- At least 10 additional highly prospective targets
have been identified on the Tanda-Iguela property
-- An aggressive 70,000 m drill programme is planned for
2023 to both delineate further resources at Assafou
and test new targets
-- Preliminary metallurgical tests indicate high gold
recovery rates of above 95% with a significant
portion recoverable by gravity
Abidjan, 21 November 2022 -- Endeavour Mining plc (LSE:EDV,
TSX:EDV, OTCQX:EDVMF) ("Endeavour", the "Group" or the "Company")
is pleased to announce that a major discovery has been made at its
100%-owned Tanda-Iguela greenfield exploration property in Côte
d'Ivoire. The Tanda-Iguela property has the potential to be another
flagship asset for Endeavour, given the size of the maiden resource
and its significant exploration potential as 10 additional nearby
targets have been identified.
Following highly encouraging initial results obtained in 2021,
an intensive drilling programme conducted in 2022 resulted in the
rapid delineation of a maiden resource estimate for the Assafou
target, as presented in Table 1 below.

Mineral Resource Estimate current as at 31 October 2022. No
Measured resources have been estimated. Mineral Resources estimates
follow the Canadian Institute of Mining, Metallurgy and Petroleum
("CIM") definitions standards for mineral resources and have been
completed in accordance with the Standards of Disclosure for
Mineral Projects as defined by National Instrument 43-101. Reported
tonnage and grade figures have been rounded from raw estimates to
reflect the relative accuracy of the estimate. Minor variations may
occur during the addition of rounded numbers. Mineral Resources
that are not Mineral Reserves do not have demonstrated economic
viability. Resources were constrained by $1,500/oz gold price MII
Pit Shell and based on a cut-off of 0.5 g/t Au.
Significant exploration potential exists at the Assafou deposit
since it is open along strike in both directions and at depth. The
delineated Indicated resource encompasses only 20% of the
identified mineralised system which covers an area three kilometres
long by 350 metres wide. As such, an aggressive exploration
drilling campaign is scheduled to begin in 2023, with an additional
50,000 metres expected to be conducted on the Assafou deposit,
compared to the 58,000 metres of drilling, which formed the basis
of the maiden resource calculation. In addition, a drilling
programme of 20,000 metres is planned to test the additional nearby
targets identified to date. These efforts are expected to yield an
updated resource estimate in 2023 and increase the overall
geological understanding of the area.
Sébastien de Montessus, President and CEO commented: "We are
thrilled with the maiden resource at our Tanda-Iguela greenfield
property in Côte d'Ivoire. It ranks as one of the most significant
discoveries made in West Africa over the last decade and shows
potential to be another flagship asset for the company.
This discovery builds on our recent success discovering the
Lafigué project, where construction was recently launched, and
reinforces our ability to organically source our project pipeline
through ongoing exploration success. Additionally, this discovery
showcases West Africa's geological potential, which is a key reason
behind its rapid growth into the largest gold producing region
globally. As the largest gold producer in West Africa, we have
developed a strong competitive advantage in the region,
strategically positioning us to continue to unlock value over the
long term.
With this new important discovery and exploration success across
our portfolio, we are well on track to achieve our target of
discovering between 15 to 20 million ounces for the 5-year period
ending in 2025."
Patrick Bouisset, Executive Vice President Exploration and
Growth said: "After securing long mine lives at our flagship mines
through brownfield exploration, we were excited to significantly
increase our focus on greenfield exploration this year, with the
goal of feeding our project pipeline following the commencement of
construction at Lafigué.
Following promising drill results late last year, Tanda-Iguela
quickly became a stronger strategic focus in 2022, and we were able
to quickly shift our efforts to accelerate its drilling by
leveraging our presence and competitive advantage in the region. As
such, we are thrilled to have quickly delineated a maiden resource
of 1.1Moz at Indicated status and a further 1.9Moz at Inferred
status, following our first significant drilling campaign on the
asset, at an industry low discovery cost of less than $10 per
Indicated ounce.
Significant exploration potential exists on the Tanda-Iguela
property with the Assafou deposit located over a structural trend
extending over 15 kilometres and remaining open in all directions
with at least 10 additional exploration targets identified nearby.
To both delineate further resources at Assafou and test new
targets, we are preparing to launch an aggressive 70,000-metre
drilling programme next year.
Based on the initial analysis of the ore characteristics and
orebody shape, we believe it should be amenable to open pit mining
as mineralisation starts at surface, whilst preliminary
metallurgical test work done to date suggests the potential for
very high gold recovery rates. The geological context, coupled with
the occurrence of greater than 30-metre thick high grade intercepts
at depth, also suggests the possibility for future underground
mining potential."
ABOUT THE TANDA-IGUELA PROPERTY
The Tanda-Iguela property is located in the Eastern part of Côte
d'Ivoire within the Boundounkou Birimian greenstone belt,
approximately 400 kilometres to the Northeast of Abidjan and 30
kilometres from the border with Ghana. The property is composed of
two exploration permits, as shown in Figure 1 in the attached
PDF.
The Tanda permit, covering 395 km(2) , was introduced into
Endeavour's portfolio in late 2015 following the transaction with
La Mancha. The first exploration work was initiated in the early
2000s, by the previous owner, resulting in the identification of
several targets through the geochemical campaigns (9,056 samples
collected) and following a sparse drilling campaign which comprised
1,346 metres of Auger drilling over 136 holes, 7,410 metres of
Reverse Circulation ("RC") drilling over 79 holes and 1,627 metre
Diamond Drilling ("DD") over 19 holes.
Endeavour conducted an initial small drilling campaign in early
2016 with 5,324 metres of RC drilling over 76 holes on the Tanda
permit. This programme yielded strong results and the grounds
adjacent to the Tanda permit were quickly identified as being
highly prospective with the possibility to delineate a resource of
critical size to justify a standalone operation.
As such, Endeavour consolidated the area in May 2017 by being
awarded the Iguela permit, covering 298 km(2) , through the
permitting application process. Shortly after, during 2018 and 2019
an initial geochemical campaign, comprised of 3,436 samples, was
conducted over the Iguela permit. This campaign coupled with
considerable fieldwork and mapping outlined a series of significant
potential gold occurrences and exploration targets over the
tenement package, as shown in Figure 1 in the attached PDF, with
the most attractive anomalies located right over the structural
contact, extending over more than 15 kilometres, and separating the
Birimian volcanics and the Tarkwaian sediments.
Due to the exciting positive initial assay results from the
Assafou target, including multiple thick high-grade gold
intercepts, most of the drilling was quickly focused on the target
to define a maiden resource which is based on a total of 303
drillholes amounting to 58,388 metres.
In addition, ten other exploration targets have been identified
within the Tanda-Iguela exploration licenses, and at least two
(Broukro and Gbabango) are directly on trend with the prolific
Assafou mineralised system, as shown in Figure 1 in the attached
PDF.
ABOUT THE ASSAFOU DISCOVERY
The delineated resource for the Assafou deposit is very robust,
due to its relative high-grade and continuous mineralisation, as
demonstrated with the sensitivity analysis performed at various
gold prices, presented in Table 2 below.

Mineral Resource Estimate current as at 31 October 2022. No
Measured resources have been estimated. Mineral Resources estimates
follow the Canadian Institute of Mining, Metallurgy and Petroleum
("CIM") definitions standards for mineral resources and have been
completed in accordance with the Standards of Disclosure for
Mineral Projects as defined by National Instrument 43-101. Reported
tonnage and grade figures have been rounded from raw estimates to
reflect the relative accuracy of the estimate. Minor variations may
occur during the addition of rounded numbers. Mineral Resources
that are not Mineral Reserves do not have demonstrated economic
viability. Resources were constrained by MII $1,500/oz Pit Shell
and for sensitivity purpose by MII $1,300/oz, $1,700/oz and
$1,900/oz pit shells and based on a cut-off of 0.5 g/t Au.
As shown in Figure 2 in the attached PDF, the Assafou
mineralised system has now been defined over an area which is
approximately three kilometres in length and 350 metres in width,
extending from surface to depths exceeding 300 metres. The 2022
delineated Indicated resource covers only 600 metres of the defined
mineralised area with the deposit remaining open along strike in
both directions, as well as at depth.
The Assafou deposit is hosted within Tarkwaian Sediments
(sandstones) at or immediately in the vicinity of a major
structural contact with mafic Birimian rocks. As shown in Figures
3, 4 and 5 in the attached PDF, the deposit comprises a main thick
(up to 60 metre) continuous lense, appearing to be low angle to
flat-lying, overlaid by a series of stacked low angle dipping
lenses, that are distributed from the surface (in the saprolite)
down to over 200 metres depth, recognised so far. Some of the best
holes drilled in the thicker part of the mineralisation delivered
total cumulative intercepts exceeding 90 to 100 metres in true
thickness with an average grade above 3.00g/t gold.
As shown in Figure 6 in the attached PDF, step back drilling
returned high-grade intercepts, very close to the structural
contact, outside of the current resource boundary, confirming that
mineralisation is still open towards the Northwest. Some high grade
mineralised intercepts were also encountered in this area at great
depth (> 300-metre vertical) close to the main structural
contact, as demonstrated by Hole IGRCDD22-204 with intercepts of
29.7 metres at 6.36 g/t gold.
As shown in Figures 7 and 8 in the attached PDF, the mineralised
system was also identified to continue over two kilometres away
from the delineated Indicated resource area, towards the southeast.
Ground geophysical surveys (including magnetic, IP-Resistivity and
gravity) are currently on-going over the Assafou target with the
goal of outlining the contact between the sandstones and the mafic
rocks, and to better identify the extensions of the deposit.
In the Figures in the attached PDF, the parameters used to
calculate the composites are: a cut-off sample of 0.3 g/t gold, a
minimum value composite of 0.5 g/t gold, a dilution of two metres,
a minimum composite length of two metres, and the including is
based on a > 10g/t gold filter. Composite interval represent
calculated downhole (true) thickness.
PRELIMINARY METALLURGY
Preliminary metallurgical tests, completed at Endeavour's Ity
mine, included five Assafou variability samples representative of
the so far identified ore resource facies: (1) perched lens --
medium grade, (2) perched lens -- high grade, (3) thick lens -
medium grade, (4) thick lens - high grade, and (5) saprock.
Testwork focussed on gravity gold recovery with cyanidation of the
gravity tail. Gold recoveries were high from all facies with high
gravity gold recovery of between 55% to 75%, and high overall gold
extractions of above 95%.
The Assafou deposit appears to be monometallic containing no
potentially penalising elements associated with the gold.
NEXT STEPS
-- Comprehensive ground and airborne geophysical surveys (including magnetic,
IP-Resistivity and gravity) are being designed and will be executed in
2023.
-- An aggressive drilling delineation campaign is planned for 2023 over the
Assafou target, with at least 50,000 metres of RC and DD expected to be
conducted.
-- In addition, 20,000 metres of drilling is planned for 2023 to test some
of the 10 additional targets, on which very limited exploration has been
conducted to date. Information received is expected to orient a second
phase of more systematic exploration on the best identified targets.
TECHNICAL NOTES
Assafou Geology
Within the Assafou deposit, gold mineralisation occurs both
within a network of quartz veins and breccia crosscutting the
sandstones, and as disseminated occurrences within pervasively
altered sandstones. The Tarkwaian sandstones have been subject to
several alteration phases comprising early white mica
crystallisation (in both barren and mineralised sandstones), often
followed by a silicification episode coeval with gold deposition
and a later carbonatation (in both barren and mineralised
sandstones). Gold is closely associated with pyrite +/-
chalcopyrite and, very locally, galena. The more intense the
silicification (and presence of pyrite), the more mineralised the
sandstones tend to be.
The gold-bearing quartz vein network appears to have developed
during the reverse reactivation of the initial normal basin border
fault separating the sandstones (in the hanging wall) from the
Birimian basement. Mineralising hydrothermal fluids filled the open
spaces and fractures induced by the fault-related compressive
stress regime and mostly invaded the sandstones, which displayed a
higher initial remaining porosity/permeability and competency than
the mafic rocks.
Assafou Resource Modelling
The statistical analysis, geological modelling and resource
estimation were prepared by the Endeavour resource team, under the
direction of Kevin Harris (CPG) VP Resources for Endeavour as the
Qualified Person as defined by NI 43-101.
The Assafou Mineral Resource model was developed in Seequent's
Leapfrog Geo and Maptek Vulcan software. The database used to
generate the Mineral Resources comprised some 303 drillholes, with
a total drilling meterage of 58,388 metres. The majority of the
available drillhole data were drilled in 2022 and supported by
industry standard quality assurance and quality control systems,
with quality control sampling comprising blanks, coarse blanks,
certified reference materials, and field and pulp duplicates.
Resource team has reviewed the QAQC data and are confident they are
of high standard to be used in resource estimation.
Mineralisation domains were modelled using geology and grade
continuity as veins, by selecting intervals which forms part of
each mineralisation lenses; a nominal cut-off of 0.5g/t together
with presence of Silica Alteration or quartz vein zones were used.
The gold assays from the drillholes were composited to 1.0 metre
intervals within the modelled veins. Capping varied depending on
the mineralised domain, between no cap and 45g/t.
Density measurements from 38 drillholes for total 751 samples
and covering each of the material type and major lithologies, were
averaged based on the material type. Average density values were
applied to the associated portions of the block model as outlined
below:
-- Laterite: 1.62 g/cm3
-- Saprolite: 1.62 g/cm3
-- Saprock: 2.38 g/cm3
-- Fresh: 2.75 g/cm3
Gold grades were estimated using Inverse Distances Squared for
all the modelled mineralisation and estimated in multiple passes to
define the higher confidence areas and extend the grade to the
interpreted mineralised zone extents. Any block not estimated after
the Third pass is left as waste block.
The grade estimation was validated with visual and statistical
analysis, and comparison with the drilling data on sections with
swath plots comparing the block grades with the composites.
The quality and spatial distribution of the data used and the
geological continuity of the mineralisation and the quality of the
estimated block model for Assafou is sufficient for the reporting
of Indicated and Inferred Mineral Resources, Indicated Mineral
Resources have typically been defined in areas with a drillhole
spacing of 30-40 metres along sections, and 40-50 metres between
sections, where there is a reasonable level of confidence in
geological and grade continuity. Inferred Mineral Resources have
typically been defined in areas with a drillhole spacing of 50 to
80 metres, and where the continuity is much reduced.
Mineral Resources are reported within a Whittle optimised pit
shell using cut-off of grades of 0.5 g/t gold. Optimisation
parameters used are as below:
-- Ore mining cost: $2.10/t Oxide; $2.40/t Transition; $3.12/t for Fresh
-- Waste mining cost: $3.00/t
-- Processing cost: Oxide/Transition: $9.30/t; Fresh: $11.00/t
-- Selling cost: $80/oz gold
-- Mining recovery: 95%
-- Mining dilution: 0%
-- Strip ratio: 5.9
-- Processing recovery: Varies dependent on head grade. Averages 92% for
each of the three material types
-- Average slope angles: 43deg
-- G&A cost: $5.60/t processed
Drilling, Assay, Quality Assurance / Quality Control
Procedures
Reverse Circulation ("RC") and Air Core ("AC") drilling delivers
material to the surface via percussion hammer pushing pulverized
rock into dule tube rods which evacuate the material to the surface
via high pressure compressed air.
The samples are collected from the cyclone at surface at 1-metre
intervals. The cyclone is cleaned after every 6-metre rod by
flushing the hole. Additional manual cleaning is required in
saprolitic or wet ground, closely monitored by the site geologist /
geotechnician to ensure no sample to sample contamination
occurs.
Samples are split at the drill site using several different
riffle splitters, based on bulk sample weight. 2-5kg laboratory and
a second 2-5kg reference sample are collected. Bulk and laboratory
sample weights, in addition to moisture levels are recorded.
Representative samples for each interval were collected with a
spear, sieved into chip trays and retained for reference.
Drill core (PQ, HQ and NQ size) samples are selected by
Endeavour geologists and sawn in half with a diamond blade at the
project site. Half of the core is retained at the site for
reference purposes. Sample intervals are generally 1 metre in
length.
All samples are transported by road to Bureau Veritas in
Abidjan. Each laboratory sample is secured in poly-woven bags
ensuring that there is a clear record of the chain of custody. On
arrival samples are weighed. Complete samples are crushed to 2 mm
(70% passing) with 1 kg split out for pulverization. The entire 1
kg is pulverized 75<MU>m (85% passing). A 50 gram sample is
extracted and analysed for gold using standard fire assay
technique. An Atomic Absorption ("AA") finish provides the final
gold value.
Blanks, field duplicates and certified reference material
("CRM's") are inserted into the sample sequence by Endeavour
geologists at a rate of 1 of each samples type per 20 samples. This
ensures that there is a 5% Quality Assurance / Quality Control
("QA/QC") sample insertion rate applied to each fire assay batch.
The sampling and assaying are monitored through analysis of these
QA/QC samples. This QA/QC program was audited by a consultant,
independent from Endeavour Mining and has been verified to follow
industry best practices.
In September 2022, 1,758 samples were sent to ALS Ouagadougou
for umpire (referee) analysis. Comparison of the Original analysis
against the umpire analysis revealed a very strong Correlation
Coefficient of 96% suggesting that the original assays provided by
Bureau Veritas in Abidjan are accurate. Core sampling and assay
data were monitored through a quality assurance/quality control
program designed to follow NI 43-101 and industry best
practice.
