The Houndé mine is one of Endeavour’s cornerstone                                            3Mtpa CIL Plant
assets. The mine was built ahead of schedule                                               Expected mine life:
and below budget, with commercial production                                                   +10 years
commencing in Q4-2017. Since then, the CIL plant has                                           Workforce:
consistently performed well and is able to operate                                                1,860

at more than 30% above nameplate capacity.
The goal is to delineate sufficient additional resources through near-mine
exploration to sustain production above 250koz/year over a +10-year life of
mine at an attractive AISC. In July 2020, a mining permit was granted and
mining commenced at the Kari Pump deposit, part of the Kari Area, which will
                                                                                       240-260koz
provide mill feed at significantly higher grades than the current active pits.

operation with significant exploration potential.                                       Expected mine life:
The mine was built on time and on budget by                                                   +7 years
the previous owners, SEMAFO, and achieved                                                   Workforce:
commercial production in Q3-2018.                                                             ~1,100

The mine was placed on temporary care and maintenance in November
2019 in order to address regional security issues and started processing
stockpiles in Q1-2020. Full mining operations restarted in Q4-2020. The area
around the mine is virtually unexplored and significant opportunity exists to
identify additional resources.

Wahgnion is located in the southwest corner of                                           2.9Mtpa – 3.0Mtpa CIL Plant
Burkina Faso near the border of Côte d’Ivoire.                                               Expected mine life:

Since achieving commercial production in November 2019, the plant has been
performing at ~25% above designed capacity for gold recovery and throughput.                     Workforce:
                                                                                                    1,101
The mine plan for Wahgnion focuses on open-pit mining of four initial
gold deposits within the mine lease. The Nogbele, Fourkoura and Stinger
deposits fall into the Nogbele land tenement while the Samavogo deposit
is in the Dierisso tenement. A multi-year drill program is underway at these
four deposits with a goal of extending the mine life. Additionally, there are
more than one dozen drill-ready targets on the regional land package, which                      149koz
have the potential to become resources and are within trucking distance of                        Production

                                            Greenstone Belt, Fetekro was ranked as a top greenfield target, following our strategic exploration review in late 2016.
                                            A maiden resource for the Lafigué target was published in October 2018, with an updated indicated resource of 1.2Moz
                                            published in September 2019, on which an initial PEA was based, already demonstrating robust project economics
                                            including a pre-tax NPV5% of $372m and an IRR of 37% at a $1,500/oz gold price.
                                            In 2020, the Indicated resource for the Lafigué deposit grew by 108% to 2.5Moz at 2.40g/t Au and the Lafigué resource
                                            estimate now encompasses a mineralized area extending over 2km long by 1km with the deposit remaining open at
                                            depth and along strike. The 2.5Moz Fetekro resource has been found at a very low discovery cost of $7.50 per Indicated
                                            resource ounce.
                                            The Lafigué resource is of high quality, with metallurgical testwork indicating gold recovery of over 95%, with a
                                            significant portion recoverable by gravity. There is no large relocation required and the property is located close to
                                            existing infrastructure, including sealed roads and grid power.
                                            A PFS based on the larger 2.5Moz Indicated resource is expected to be published in Q1-2021.

NABANGA PROJECT
The Nabanga Project was acquired by Endeavour in July 2020 as part of the SEMAFO transaction.
Located approximately 250km southeast of Ouagadougou, the capital city of Burkina Faso,
Nabanga is an early stage project which consists of three exploration permits covering 178.5km²:
Kamsongo, Napadé and Nabanga.
The previous owners completed a Preliminary Economic Study on the project in September 2019 which
indicated the potential for an economic project with an after-tax NPV (5%) of $100m based on an
Inferred resource of 841koz. Endeavour is currently evaluating this project in the context of its overall
exploration portfolio and will determine next steps during the year.

project covers more than 1,400 km2 including the Afema mine license and                      and feasibility studies
three exploration permits.
Afema includes a historical near-surface oxide and sulphide resource and lies
within an area hosting several gold mineralized structures on extensions from prolific gold belts in Ghana. The Woulo
Woulo prospect is the most recent discovery at Afema. Currently, multi-drill exploration campaign is underway at the
Woulo Woulo prospect, the Niamienlessa structural trend and the Afema Shear and an initial resource estimation is
targeted for completion in the first half of this year.
As of January 2021, more than 550 holes have been drilled, totaling nearly 51,000 metres. Next steps include expanding
trenching and drilling to new areas of interest within the Afema mining license and outward onto the three regional
exploration permits. As well, early-stage metallurgical test work as well as environmental and social assessments are
expected to be initiated in the near-term.

                                            and are proud to support over 1,000 West African businesses and to source

                                            development of local talent into management roles.
                                            As members of the World Gold Council, we have pledged to implement the
                                            Responsible Gold Mining Principles (RGMPs).
                                            The RGMPs reflect the commitment of the world’s leading gold producers to
                                            responsible mining. The Principles provide an over-arching framework that sets
                                            out clear expectations as to what constitutes responsible gold mining to provide
                                            confidence to investors, supply chain participants and ultimately, consumers.

1. 	The Mineral Resources and Reserves have been estimated and reported in accordance with Canadian National Instrument
     43-101, ‘Standards of Disclosure for Mineral Projects’ and the Definition Standards adopted by CIM Council in May 2014.
2. 	Mineral Resources that are not Mineral Reserves do not demonstrate economic viability.
3. 	Mineral Resources are reported inclusive of Mineral Reserves.
4. 	Tonnages are rounded to the nearest 100,000 tonnes; gold grades are rounded to one decimal place; ounces are
     rounded to the nearest 1,000 oz. Rounding may result in apparent summation differences between tonnes, grade and
     contained metal.
5. 	Tonnes and grade measurements are in metric units; contained gold is in troy ounces.
6. 	Processing recoveries vary at each pit by many factors including material types, mineralogy and chemistry of the ore.
     The overall average recoveries are around 92% at Boungou, 91% at Hounde, 83% at Ity, 87% at Mana, 82% Karma,
     88% at Sabodala, 93% at Wahgnion, 94.7% at Fetekro and 90.5% at Kalana.
7. 	The reporting of Mineral Reserves and Resources are based on a gold price as detailed below:
