Sebastien de Montessus, President and CEO, commented: We are very pleased with our strong performance during the third quarter, which positions us to achieve our annual guidance set at the beginning of the year despite the ongoing challenges presented by the global COVID-19 pandemic.

Our Net Debt has decreased by 71% over the last 12 months, with nearly $300 million reduced during the third quarter alone, allowing the Group to boast a healthy leverage ratio of below 0.3x as we quickly approach a net cash position. We look forward to delivering a record-breaking fourth quarter, as we expect an even stronger performance given the restart at Boungou, higher grades at Hound and the end of the rainy season.

Given our strong balance sheet and expected robust free cash flow generation, we are pleased to announce our first dividend at an attractive yield as part of our capital allocation framework and strategy of maximizing shareholder value. Our goal is to maintain a similar dividend yield until we have reached a targeted net cash position of $250 million. Once this targeted net cash position is reached, we would be well positioned to re-assess our capital allocation priorities, which include increasing our shareholder return program. In addition to increasing our cash flow generation in the short term, we are also well positioned to deliver medium and longer-term value creation. We see potential to continue to optimize and extend the mine lives at both Ity and Hound and are now deploying the same strategy at the recently acquired, and swiftly integrated, Boungou and Mana mines. We are also continuing to build optionality within our portfolio by aggressively advancing our attractive pipeline of projects, where efforts are currently being prioritized on fast tracking our Fetekro Project to a pre-feasibility study in Q1-2021.

The progress we have made across our business over recent years is bearing fruit as we have created a compelling investment proposition. We are now focused on further enhancing our capital markets appeal, by paying dividends and evaluating a secondary listing, both with a focus on driving incremental investor demand through notably increased index inclusions.

ENDEAVOUR DECLARES FIRST DIVIDEND

Endeavour is pleased to announce that, based on its expected robust free cash flow generation, its Board of Directors has declared a first dividend of $60 million for the 2020 fiscal year, payable in early Q1-2021. This first dividend equates to approximately $0.37 per share (C$0.48 per share) and represents a 1.6% yield based on Endeavours closing price on November 11, 2020. The Company expects to announce the record date later in Q4-2020.

This first dividend sets the path to a sustainable dividend policy, based on its capital allocation framework and its strategy of maximizing long term shareholder value. Following the payment of this first dividend, the Board of Directors expects to declare future dividends on a semi-annual basis, with the goal of maintaining a similar dividend yield until it has reached a targeted net cash position of $250 million. Once that target is reached, the Company would be well positioned to re-assess its capital allocation priorities, which may include augmenting its shareholder return program.

COVID-19 UPDATE

Since the outbreak of the global COVID-19 pandemic, Endeavour has focused on the well-being of its employees, contractors and local communities, while ensuring business continuity. In addition, host governments in Cte dIvoire, Burkina Faso and Mali have taken strict and pro-active measures to minimize overall exposure in their countries.

Protecting the well-being of employees, contractors, and local communities

-- Endeavour has implemented a range of preventative measures across all its sites, including social distancing, health screening, augmented hygiene and restricted access to sites. -- Endeavour operates in close coordination with the national health authorities and is using the epidemiological surveillance system it developed to assist host countries (Cte dIvoire, Burkina Faso and Mali) with the monitoring and tracking of the pandemic in these countries. -- Endeavours donations of key medical equipment and supplies to regional, community and on-site medical centers continued during the quarter across all three countries of its projects and operations. -- A range of community programs were implemented during the quarter including micro-credit programs, which help to support people in host communities whose livelihoods have been impacted by the pandemic, and e-learning programs in Burkina Faso to facilitate access to distance learning for students.

Business continuity response plan

-- In early March 2020, Endeavour put in place a business continuity plan to mitigate the risks and potential impact of the global COVID-19 pandemic, which has three levels of response: Level 1, which the Group is currently operating under, involves a range of preventative measures including temperature checks, restricted access to sites, social distancing, increased hygiene standards and mandatory quarantine periods for employees arriving in-country, while otherwise continuing operations as normal. Level 2 is designed to be initiated should COVID-19 become more prevalent in the countries in which the Group operates and involves comprehensive restrictions on movement into and out of the mines. Under these circumstances, Endeavours mines would be isolated, but mining operations and the shipment of gold would continue. Level 3 involves the full or partial suspension of mining and processing operations. -- Each of Endeavours operations are continuing to operate at normal levels with gold shipments and sales continuing, albeit with increased health and safety measures and decreased efficiencies in some parts of the operations. -- Employees in a role that enabled them to work from home were asked to do so. The Corporations cloud-based strategy ensured that employees could access all the relevant applications, systems and collaboration tools that they needed to perform their duties. In addition, the cyber security response was updated and is constantly tracked in light of the increased cyber security risk generally observed during the pandemic.

OPERATIONAL PERFORMANCE SUMMARY

-- Continued strong safety record for the Group, with a low Lost Time Injury Frequency Rate (LTIFR) of 0.14 for the trailing 12 months. -- Endeavour remains on track to achieve its pro forma Group FY-2020 production guidance of 995 1,095koz at an AISC of $865 $915/oz, despite the COVID-19 pandemic. The fourth quarter is expected to be the strongest quarter of the year given the recent restart of mining operations at Boungou and the processing of higher grade ore from the Kari Pump deposit at Hound.

-- Q3-2020 consolidated production amounted to 244koz, an increase of 95koz or 64% over Q2-2020, due to the addition of the Mana and Boungou mines, as well as increased production at Hound, Karma and Agbaou, which was slightly offset by a modest decrease at Ity. AISC decreased by $33/oz or 4% to $906/oz as lower costs at Hound and Ity, as well as the addition of Mana and Boungou, more than offset increased costs at Agbaou and Karma and higher royalty costs due to the strong gold price. -- YTD-2020 consolidated production amounted to 565koz, an increase of 92koz or +19% over YTD-2019 as a full nine months of Ity and the addition of Mana and Boungou more than offset an expected decline in production at Agbaou. AISC increased due to expected increases at Agbaou, Ity and Hound, as well as the addition of a full quarter of operations at Mana, which were partially offset by lower unit corporate costs and the addition of the low cost Boungou mine.

AGBAOU MINE

Q3 2020 vs Q2 2020 Insights

-- Production remained flat as an increased proportion of the mill feed was comprised of higher grade fresh ore, which compensated for the guided reduction in plant throughput. Total tonnes mined increased by 16% as activities focused on the deeper elevation and fresh material zones of the North pit and the South pit with marginal contribution from the West pit. Tonnes of ore mined decreased due to greater emphasis on waste extraction, as demonstrated by the significant increase in the overall strip ratio.Tonnes milled decreased due to the planned higher proportion of fresh ore in the mill feed. Processed grades increased as a result of higher grade ore from the fresh zones of the North pit and the South pit which were partially offset by lower grade stockpiles used to supplement the plant feed.Recovery rates remained stable at 94%. -- The AISC increased mainly due to higher sustaining capital, royalties and unit G&A costs offset by lower unit mining and processing costs. Mining unit costs decreased from $2.76 to $2.66 per tonne mined despite mining harder ore and normal rainy season impacts, due to the volume effect of increased tonnes mined. Processing unit costs decreased from $8.88 to $8.52 per tonne mainly due to savings in power cost due to lower tonnes milled. Sustaining capital costs increased from $1.4 million to $3.9 million primarily due to the higher capitalized waste as deferred sustaining capital from H1-2020 was incurred during this quarter. -- Non-sustaining capital remained low, marginally increasing from $0.3 million to $0.4million.

YTD-2020 vs YTD-2019 Insights

-- As guided, production decreased due to lower grades while tonnage processed and recovery rates remained flat. -- AISC increased as a result of higher unit mining costs, unit processing costs, higher royalties and lower ounces sold which were offset by lower sustaining capital and G&A unit costs.

Q4 and 2020 Outlook

-- Production is expected to increase in Q4-2020 over Q3-2020 due to higher processed grades and tonnage. As such, Agbaou is expected to achieve the bottom end of its FY-2020 production guidance range of 115,000125,000 ounces and the middle of its AISC guidance range of $940$990 per ounce despite higher royalty costs. -- Mining is expected to continue principally in the North and South pits with contributions from West pit 5 ceasing during the quarter. Throughput is expected to increase following the end of the rainy season while recovery rates are expected to slightly decrease due to greater volumes of harder fresh ore processed. -- Sustaining capital spend for FY-2020 is expected to be below initial guidance of $17.0 million (of which $10.7 million has been incurred to date) due to less capitalized waste, while non-sustaining capital is expected to be in line with the guided $1.0 million (of which $0.9 million has been incurred to date).

Exploration Activities

-- An exploration program of up to $2.0 million was planned for 2020 with the aim of continuing to test targets located along extensions of known deposits and on parallel trends. -- Minimal work was done thus far as Cte d'Ivoire exploration efforts were concentrated on Ity and Fetekro.

BOUNGOU MINE

Q3 2020 vs Q2 2020 Insights

-- Production remained flat as increased plant throughput offset the lower-grade mill feed, as higher-grade ore stockpiles were prioritized in the previous quarter. Mining operations restarted in Q3-2020, with activities focused on extracting readily available ore with no drill and blast requirements utilizing a local surface haulage contractor. Tonnes milled increased due to increased mill availability despite a seven day shut for full liner changes in both the SAG Mill and Vertical Tower Mill ("VTM"). The plant feed originated mainly from stockpiled material, which was supplemented by easily accessible high grade ore from the pits. As expected, the processed grade decreased due to the declining grade profile of the available ore stockpiles. Recovery rates remained flat as the characteristics of the ore milled remained similar to Q2-2020. -- As expected, AISC increased due the processing of lower grade stockpiles and a higher royalty costs. Open pit mining unit costs amounted to $11.7 per tonne, which are relatively high due to the use a surface works contractor with small excavator and trucks on an hourly hire basis to accelerate access to higher grade ore whilst the main contractor mobilized to site. Although not overly productive, this option did bring additional ounces forward into Q3-2020.Processing unit cost decreased from $39.30 to $35.12 per tonne as a result of increased volumes of ore processed, despite being impacted by a seven day shutdown for full liner changes in both the SAG Mill and VTM.Sustaining capital of $0.5 million increased from $0.1 million in Q2-2020 mainly due to planned road maintenance cost. -- Non-sustaining capital of $0.8 million was flat over Q2-2020 with expenditure which relates to infrastructure upgrades and the construction of the air strip.

Q4 and 2020 Outlook

-- Production and AISC are expected to improve in Q4-2020 due to the restart of mining operations, and as such Boungou is expected to achieve the top half of its FY-2020 pro forma production guidance of 130,000 - 150,000 ounces at an AISC at the bottom half of the previously guided $680 - 725 per ounce. -- As announced in early September, Endeavour awarded the mining contract to SFTP Mining BF S.A.R.L (SFTP), a West African mining contractor, who also provides mining services at Endeavours Karma mine. SFTP immediately began to mobilize mining equipment and personnel and, to accelerate the restart, SFTP purchased a some of the on-site fleet from the previous contractor. -- Mining, drilling, and blasting activities have ramped up in early Q4-2020 and are expected to reach the contracted amount of approximately 2.0 million tonnes per month in Q4-2020. During Q4-2020, mining activities are expected to focus on the West pit, while preparing the East pit for grade control drilling in 2021.

Exploration Activities

-- In 2020, a $1.0 million exploration program was planned, which comprised 5,000 meters of reverse circulation drilling. -- Exploration activities are expected to resume in Q4-2020, targeting near-mill targets.

HOUND MINE

Q3 2020 vs Q2 2020 Insights

-- Production increased due to higher processed grades which more than offset the slightly lower throughput, while the recovery rate remained consistent with Q2-2020. Total tonnes mined declined by 14% due to the normal rainy season impact, however tonnes of ore mined increased by 15% due to the commencement of mining at Kari Pump. Ore continued to be sourced primarily from the Vindaloo Main, Vindaloo Central and Kari Pump pits and supplemented Bour and Vindaloo North pits. Mining activities commenced at the high grade Kari Pump deposit during the quarter, with over 60,000 meters of grade control drilling completed, pre-stripping is well underway and first ore extraction achieved. The strip ratio was lower than guided due to a greater focus on ore extraction from the Vindaloo pits and Kari Pump. Tonnes milled remained flat, despite the rainy season, as oxide ore from Kari Pump offset the impact of greater volumes of fresh ore from Vindaloo. Average processed grades increased due to the benefit of higher grade ore from Vindaloo Main and Vindaloo Central, which was supplemented by high grade Kari Pump ore.Recovery rates remained flat. -- AISC decreased mainly due to a decrease in sustaining capital, lower processing unit costs and slightly higher sales volumes which more than offset higher royalties and higher mining and G&A unit costs. Mining unit costs increased from $2.15 to $2.74 per tonne due to the impact of the rainy season (lower volumes, more pumping and lower mining and haulage efficiencies), coupled with higher maintenance costs due to timing of planned work, plus higher grade control drilling and drill and blast costs associated with mining greater volumes of Vindaloo fresh ore. Processing unit costs decreased from $14.31 to $13.11 per tonne, despite the rainy season, as costs were higher in Q2-2020 due to mill liner replacement.Sustaining capital decreased decreased from $11.1 million to $7.0 million due to lower waste classified as sustaining capital. -- Non-sustaining capital increased from $5.8 million to $7.3 million, higher than initial guidance, with the aim of accelerating the development of the Kari area (more waste extraction, advanced timeline for resettlement, and additional satellite mining infrastructure).

YTD-2020 vs YTD-2019 Insights

-- Production increased due to slightly higher processed tonnes and grades with recovery rates remaining flat. AISC increased due to higher sustaining waste capitalization, higher royalty costs and a shift to mining and processing a higher proportion of harder fresh ore.

Q4 and 2020 Outlook

-- Production is expected to significantly improve in Q4-2020 over Q3-2020 due to higher processed grades. Hound is expected to achieve the top end of its FY-2020 production guidance range of 230,000 - 250,000 ounces and the mid-range of its AISC guidance of $865$895 per ounce in light of higher royalty costs. -- Higher grade ore is planned to be processed in Q4-2020 with mill feed from Vindaloo Main and Central supplemented by Kari Pump while mill throughput and recovery rates are expected to remain flat. Greater waste extraction is expected as mining activities continue to ramp up at Kari Pump and as the delayed stripping at Vindaloo is continued. -- Sustaining capital spend for FY-2020 is expected to be significantly below the initial guidance of $49.0 million (of which $29.9 million has been incurred to date) mainly due to lower volumes of waste extracted during the year which impacts the stripping ratio and thus allocation to capital. Non-sustaining capital spend for FY-2020 is expected to amount to approximately $25.0 million (of which $14.9 million has been incurred to date), higher than the initial guidance of $10.0 million, primarily due to a greater focus on the development of the Kari area including pre-stripping, fencing and infrastructure and resettlement costs for Kari Pump, plus land compensation for the newly discovered Kari West and Centre deposits, which has been brought forward in order to secure that area for mining in 2021.

Exploration

-- An exploration program of $11.0 million totaling approximately 94,000 meters was initially planned for 2020, with the aim of delineating additional resources in the Kari area and at the Vindaloo South and Vindaloo North targets. In addition, other targets such as Dohoun and Sia/Sianikoui were expected to be tested. -- In YTD 2020, $17.0 million was spent, comprised of nearly 74,000 meters drilled, with up to 11 rigs active. Over 44,000 meters were drilled for geotechnical and metallurgical purposes at Kari West, Kari Centre and Kari Gap, and sterilization and grade control at Kari Pump. A small reconnaissance drilling campaign at Vindaloo North Target 3, Sianikoui, Mambo and Marzipan was also conducted and yielded positive initial results. -- An updated resource estimate, incorporating 554,000 additional Indicated ounces for the entire Kari area, was published in early Q3-2020. -- Maiden reserves for Kari Center, Gap, South and Pump Northeast are expected in Q1-2021.

ITY MINE

Q3 2020 vs Q2 2020 Insights

-- Production decreased slightly as higher throughput and gold recoveries largely offset the lower processed grades. Total tonnes mined increased significantly (up 18%), despite the rainy season, as additional mining equipment was added in late Q2-2020 with the aim of accelerating the development of several larger pits to provide greater operating flexibility. Mining in Q3-2020 prioritized pit cut-backs at the higher grade Ity and Bakatouo deposits. Tonnes milled increased by 11% due to a higher proportion of oxide material as well as higher mill availability and utilization following completion of plant maintenance during Q2-2020. Two power screens were commissioned in late Q3-2020 which assisted in feeding high moisture oxide content through the surge bin.Processed grade decreased slightly more than guided due to the focus on completing pit cut-backs, which consequently resulted in ore extraction being constrained to lower grade oxide ore available in upper mine areas and lower grade stockpiles supplementing the plant feed.Recovery rates increased as a higher proportion of oxide material was fed through the plant as a result of the change in mining sequence. -- AISC decreased due primarily to the lower strip ratio, an increase in gold sold, higher recovery rates, and lower unit processing costs, which were partially offset by higher unit mining and G&A costs, and higher royalty expenses. Mining unit costs increased from $3.12 to $3.81 per tonne mined due to the higher load and haul cost associated with using ADTs, timing of equipment maintenance costs, increased proportion of fresh material, which required increased drill and blast and the higher costs associated with mining in the rainy season.Processing unit costs decreased from $11.96 to $11.27 per tonne due to a higher proportion of oxide material processed and higher mill throughput. Sustaining capital remained consistent with prior periods at $2.2 million -- Non-sustaining capital decreased from $10.7 million to $3.7 million due to the completion of the Tailings Storage Facility (TSF) raise in Q2-2020 and less waste capitalization of the new Colline Sud pit, which was accelerated and largely completed in Q2-2020.

YTD-2020 vs YTD-2019 Insights

-- Production increased as the Ity CIL plant operated for the full nine month period ended September 30, 2020 compared to lesser production time for the same period in 2019 with commercial production declared on April 8, 2019. AISC increased as guided due to increased sustaining capital related to the component change-out associated with heavy mining equipment and higher royalties associated with the higher gold price.

Q4 and 2020 Outlook

-- Production is expected to improve in Q4-2020 over Q3-2020 due to higher processed grades. Due to lower than planned Q2-2020 performance (as previously described) and a lower than anticipated Q3-2020 performance (due to the stronger focus on conducting pit cut-backs), Itys full year production is expected be below the guidance range of 235,000 255,000 ounces and AISC is expected to be above the guidance of $630 $675 per ounce, which also reflects the higher royalty costs. The short-term compromises made are expected to position Ity for a stronger performance in Q4-2020 and into 2021. Endeavour remains on track to achieve its Group 2020 guidance, as Itys performance is expected to be offset by stronger performance across other mines. -- Plant feed in Q4-2020 is expected to be sourced primarily from higher-grade sulfide ore at the Daapleu pit, while continuing to be supplemented by ore from smaller satellite pits and lower grade historic heap dumps. The proportion of higher-grade fresh ore is expected to increase whilst throughput and recovery rates are expected to decline in line with the metallurgical characteristics of Daapleu sulphide ore processed. -- The Tables 14 and 15 below illustrate the various mining activities since operations began in early 2019. In 2020, Daapleu has been the main ore source with contributions from satellite deposits and historical heap leach dumps. Following the completion of the TSF lift in Q2-2020 (brought forward due to the plant volumetric upsize finalized in Q4-2019), mining in Q3-2020 prioritized pit cut-backs at the higher-grade Ity and Bakatouo deposits. Once these cut-backs are completed in 2021, the mine will be better positioned to source ore from several large deposits in order to optimize the plant feed based on metallurgical characteristics, rather than currently being constrained to mainly Daapleu.

-- Sustaining capital spend is expected to increase in Q4-2020 due to a stronger focus on accelerating the cut-backs at the Ity and Bakatouo pits. In addition, several plant optimization initiatives have been identified to increase the plant capacity from 5.0Mtpa to 5.6Mtpa with minimal capital spend. These initiatives are expected to commence in Q4-2020 and be completed in 2021 during scheduled maintenance downtimes. Sustaining capital spend is expected to total approximately $13.0 million for FY-2020 (of which $5.7 million has been incurred to date), compared to the initially guided $8.0 million. -- Non-sustaining capital spend for FY-2020 is expected to be in line with the guided amount of approximately $35.0 million (of which $25.4 million has been incurred to date) with Q4 activity primarily related to the commencement of the TSF lift 3, Le Plaque haul road and compensation, river diversions and the Ity pit cut-back.

Exploration Activities

-- An exploration program of up to $14.0 million totaling approximately 100,000 meters was initially planned for 2020, with the aim of growing the Le Plaque, Bakatouo, and Daapleu deposits, and testing other targets such as Floleu and Samuel. -- In YTD-2020, $13 million was spent, comprised of over 85,000 meters drilled, with eight rigs active over the greater Ity area. The majority of drilling was focused on the Le Plaque area and on near-mill targets such as Verse West and Leach pad and Daapleu SW. -- As announced on July 7, 2020, drilling has resulted in a 43% increase in Le Plaques Indicated resource estimate to 689,000 ounces. In addition, several other nearby targets have also been identified. At least 15,000 meters of drilling aimed at testing Le Plaque extensions and other nearby targets are planned for the remainder of 2020.

KARMA MINE

Q3 2020 vs Q2 2020 Insights

-- Production increased due to the recovery of some of the gold locked up in the heap during the previous quarter, which offset the lower grade, recovery rate and tonnage stacked. Total tonnes mined decreased by 9% due to the slowdown caused by the rainy season. Ore tonnes mined decreased by 22% due to the higher strip ratio associated with both the Kao North and GG1 pits. Ore tonnes stacked decreased due to the lower capacity to stack the wet oxide ore during the rainy season (similar overall utilization as Q2-2020 though lower average throughput rate).The stacked grade decreased due to a higher proportion of lower grade ore from the GG1 pit and low grade stockpiles used to supplement the stacked ore.Recovery rates decreased due to the leach characteristics of the high proportion of GG1 ore stacked. -- AISC increased mainly due to higher unit processing costs and royalties, which were partially offset by lower unit mining costs and sustaining capital. Mining unit costs decreased from $2.38 to $2.15 per tonne due to mining efficiencies with the new mining contractor.Processing unit costs increased from $6.56 to $7.43 per tonne due to higher use of cyanide and cement associated with the larger proportion of GG1 ore stacked.Sustaining capital costs decreased from $2.0 million to $1.5 million due to decreased capitalized waste at the Kao North pit. -- Non-sustaining capital spend decreased from $3.8million to $1.7million.

YTD-2020 vs YTD-2019 Insights

-- As guided, production increased due to the higher throughput rate associated with the upgrades to the stacking system. -- AISC decreased as a result of lower unit processing and G&A costs, a lower strip ratio and an increase in ounces sold.

Q4 and 2020 Outlook

-- Production is expected to increase slightly in Q4-2020 over Q3-2020 due to an increased stacked tonnage following the end of the rainy season, however FY-2020 production is expected to be slightly below the guidance range of 100,000 - 110,000 ounces. Despite higher royalty costs, Karma is expected to achieve the mid-range of AISC FY-2020 guidance of $980 - $1,050 per ounce. -- Mining activity is expected to continue at the Kao North pit and GG1 throughout the remainder of the year. Ore stacked grades are expected to be consistent with those seen in Q3-2020 as low grade stockpiles continue to supplement the ore stacked. -- Sustaining capital spend for FY-2020 is expected to be below the guided amount of approximately $9.0 million (of which $4.2 million has been incurred YTD-2020). -- Non-sustaining capital spend for FY-2020 is expected to be in line with guidance of approximately $9.0 million (of which all $7.6 million has been incurred YTD-2020).

Exploration Activities

-- An exploration program of up to $2.0 million was planned for 2020 with the aim of in-fill drilling and testing extensions of known deposits. -- Minimal work has been done thus far in 2020 as Burkina Faso exploration efforts were focused on the numerous Hound exploration targets.

MANA MINE

Q3 2020 vs Q2 2020 Insights

-- Production increased significantly due to higher processed grades (following stronger underground production and mining of the final open pit benches at Siou), greater throughput and higher recovery rates. Total tonnes mined from the open pit operations increased by 38% due to an increase in availability of mining and drilling equipment, which also resulted in an increase in ore extraction by 19% despite the higher strip ratio. Ore extraction focused on the Siou and Wona pits, while pre-stripping activities were conducted at the Wona pit.Tonnes of ore mined from the underground operation increased by 43% as Q2-2020 activities were impacted by a temporary halt to underground operations as a result of the implementation of preventive COVID-19 measures. Ore tonnes processed increased, despite the higher proportion of fresh blend in the feed, as Q2-2020 was impacted by a shortage of mill feed due to the halt to underground mining operations and mill downtime following a quarantine period associated with changing rosters for COVID.The processed grade increased due higher underground and open pit mined grades, while lower grade stockpiles supplemented Q2-2020 feed. Recovery rates increased due to the higher proportion of ore feed from the underground operation which has higher associated recovery rates. -- AISC decreased due to higher gold sales and lower underground and open pit unit mining costs which more than offset the higher gold royalties. Open pit mining unit costs decreased from $4.50 to $3.67 per tonne due to an increase in volumes mined and higher equipment availability which increased efficiencies.Underground unit mining costs per tonne moved decreased from $58.8 to $47.1 per tonne due to the increase in volumes mined. Processing unit costs remained flat at $21.54 per tonne as the benefit of greater volumes processed was offset by larger quantities of fresh ore. Sustaining capital decreased from $11.9 million to $4.8 million, less than guided, due to lower underground development costs and less waste classified as sustaining capital. -- Non-sustaining capital increased from $0.5 million to $9.9 million, more than guided, due to the stronger focus on conducting pre-stripping activities at Wona North Stage 4 pit.

Q4 and 2020 Outlook

-- Manas pro forma production is expected to achieve the top half of FY-2020 production guidance range of 185,000 205,000 ounces and the mid-range of pro forma AISC guidance of $1,050 $1,125 per ounce despite higher royalty costs. -- Following a stronger Q3-2020, production is expected to be lower in Q4-2020 with the completion of the Siou open pit and higher proportion of ore from Wona, while throughput and recoveries are expected to decline slightly due to this expected change in the ore blend. -- Sustaining capital spend is expected to increase slightly in Q4-2020, however is expected to be significantly below the initially guided FY-2020 amount of $70.0 million on a pro forma basis (of which $33.8 million has been incurred to date) due to a greater focus on non-sustaining underground development and pre-stripping activity at Wona. Consequently, non-sustaining capital spend is expected to increase in Q4-2020 and to approximately $25.0 million for FY-2020 on a pro forma basis (of which $10.0 million has been incurred to date), higher than the initial guidance of $2.0 million which is however offset by the lower expected sustaining capital spend.

Exploration Activities

-- In 2020, a pro forma $3.0 million budget was established to follow up targets identified by geological review with minimal work completed thus far and $1.0 million spent year to date. -- In Q3-2020, a total of over 4,000 meters of underground drilling was conducted with the aim of infill drilling a portion of the Inferred material at the southern end of the Siou underground deposit. -- In Q4-2020, reconnaissance drill programs of 27,000 meters RC and 8,000 meters core will commence, designed to evaluate northeast continuations of oxide mineralization at both the Kona (immediately north of Wona) and Siou open pits. In addition, a surface drill program of 15,000 meters is planned to evaluate continuations of underground high grade ore shoots at the northeast and southwest ends of the Siou deposit.

FETEKRO PROJECT UPDATE

-- While the main focus for 2020 is on cash flow generation, Endeavour is continuing to build optionality within its portfolio by progressing exploration and studies in its project pipeline. -- During the quarter, Endeavour announced a 108% increase in Indicated resources to 2.5Moz at an average grade of 2.40 g/t Au for its Fetekro Project in Cte dIvoire. Within the same announcement, Endeavour also presented the results from a Preliminary Economic Assessment (PEA) at Fetekro, based on the previously announced 1.2Moz Indicated resource and a 1.5Mtpa gravity/CIL plant, which demonstrated robust project economics as shown in Table 20 below.

-- While progressing on engineering design work, Endeavour recently received confirmation that no further infill drilling or metallurgical testing are required for the reserve estimation process. As such, rather than publishing an updated PEA in Q4-2020, Endeavour has decided to fast track Fetekro to Pre-Feasibility Study (PFS) stage, which is targeted for completion in Q1-2021. -- The PFS will be based on the updated 2.5Moz Indicated resource (compared to 1.0Moz for the PEA) and will define a production scenario based on a 3.0Mtpa mill throughput (compared to 1.5Mtpa for the PEA). Given its strong exploration potential, Endeavour believes that Fetekro has the potential to become a cornerstone asset with a target of +200koz per annum over 10 years at low AISC. -- In order to meet the Q1-2021 PFS delivery date, and given the expected strong results, Endeavour is currently prioritizing efforts during the following months on Fetekro over other projects within its pipeline. -- At least 15,000 meters of drilling aimed at extending the Fetekro resource and testing nearby targets are planned in Q4-2020.

EXPLORATION ACTIVITIES

-- The YTD-2020 Group consolidated exploration spend was $44 million, inclusive of approximately $4.0 million of costs related to geotechnical studies, metallurgical testing and grade control drilling. Details by asset are provided in the mine sections above. -- A total of 234,866 meters were drilled during YTD-2020, with the majority conducted in H1-2020 ahead of the rainy season. The main areas of focus were Hound and Ity near-mine exploration, aimed at extending their mine lives to beyond 10 years, and Fetekro with the aim adding optionality to Endeavours project pipeline. In addition, the greenfield program includes a 5,000-meter drilling campaign on the Tanda/Bondoukou property in Cte dIvoire, which has yielded positive results. -- The exploration budget was increased by $5.0 million to $45.0-$50.0 million post the acquisition of SEMAFO, with exploration efforts on the newly acquired assets ramping up in Q4-2020.

NOTES:

-- Gold sales increased by 95koz in Q3-2020 compared to Q2-2020 as a result of increased sales across all mines in addition to contributions from the Mana and Boungou mines, which were acquired on July 1, 2020. Gold sales increased in YTD-2020 compared to YTD-2019 due to higher production at Hound, Karma and Ity (which was commissioned in Q2-2019), in addition to the newly acquired Mana and Boungou mines. -- The realized gold price for YTD-2020 was $1,714/oz compared to $1,338/oz for YTD-2019, inclusive of the Karma stream and short term gold contracts. The Karma stream amounted to 5,000 ounces sold in Q3-2020 and 15,000 ounces sold in YTD-2020 at 20% of spot prices. The short term gold contracts, amounted to 74,839 ounces in Q3-2020 at $1,796/oz, and 124,235 ounces for YTD-2020 at an average price of $1,762/oz. The Company has no further gold hedges outstanding. -- Royalties increased from $119/oz in Q2-2020 to $125/oz in Q3-2020. The YTD-2020 royalty rate was $116/oz, up by $44/oz on YTD-2019, due to both the higher realized gold price and an increase in the underlying royalty rate based on the applicable sliding scale (above a spot gold price of $1,300/oz, government royalty rates in Burkina Faso increase from 4.0% to 5.0%, and above a spot gold price of $1,600/oz rates increase from 4% to 5% in Cte d'Ivoire). -- As shown in the table below, the sustaining capital expenditure from existing mines decreased slightly for Q3-2020 over Q2-2020 due to an increase at Agbaou, which was more than offset by a decrease at Hound, while Ity and Karma remained flat. The sustaining capital expenditure from existing mines for YTD-2020 increased compared to the corresponding period of 2019 due to scheduled waste capitalization at Hound and Ity. Further details by asset are provided in the above mine sections.

-- The All-In Sustaining Margin from existing mines for Q3-2020 and YTD-2020 increased by $25million and $115million respectively, as a result of the higher realized gold price and increase in gold sales (described in Notes 1 and 2) which was partially offset by higher cash costs, royalties, and higher mine sustaining capital spend (specifically during H1-2020). The newly acquired SEMAFO assets significantly contributed to the consolidated All-In Sustaining Margin for Q3-2020, with $107million on a combined basis.

-- As shown in the table below, the non-sustaining capital expenditure from existing mines decreased significantly for Q3-2020 over Q2-2020 mainly due to a sharp decrease at Ity. The non-sustaining capital spend from existing mines for YTD-2020 increased compared to the corresponding period of 2019, mainly due to the TSF raise and waste capitalization at Ity and waste capitalization and resettlement costs for the Kari Pump area at Hound, while spend decreased at Agbaou and Karma. Further details by asset are provided in the above mine sections.

-- The non-sustaining exploration capital spend for YTD-2020 continued to remain high, in line with Endeavours strategic objective of unlocking exploration value through its aggressive drilling campaign. Spend in Q3-2020 decreased as the majority of the exploration work planned for FY-2020 was conducted in H1-2020, ahead of the rainy season. -- The tables below summarize the Q3-2020 and YTD-2020 working capital movements

-- Taxes paid increased by $13.5 million in Q3-2020 compared to Q2-2020. This was due to corporate income tax payments made at Ity and Hound of $9.7 million and $6.5 million respectively. Taxes paid in YTD-2020 increased by $10.3million compared to the previous year mainly due to increased corporate income tax payments at Agbaou.

-- The interest paid, financing fees and lease repayments increased in Q3-2020 compared to Q2-2020 as the convertible notes coupon is payable during the first and third quarters. The amount for YTD-2020 increased slightly compared to the corresponding period of YTD-2019 mainly due to interest payment on equipment leases at Ity, as well as the interest accrued from the $120.0m drawn from the RCF during Q2-2020 which was subsequently repaid in Q3-2020. -- Cash settlements on hedge programs for YTD-2020 includes a $32 million realized loss on gold collar, and an inflow of $7million related to short-term forward sales in YTD-2020. The collar expired at the end of June 2020 with the final payment on the collar in early Q3-2020. -- Growth project spend decreased from $92 million in YTD-2019 to $4 million in YTD-2020 as the Ity CIL plant was completed in Q1-2019. The amount for YTD-2020 of $4 million relates mainly to the Kalana project. -- M&A, restructuring and asset sale activities in Q3-2020 includes $19 million in acquisition and restructuring costs. YTD-2020 includes an inflow $12 million related to the sale of mining equipment spare parts to the contract miner at Karma, which was offset by a $5 million payment for the additional interest in Ity Mine and $26 million in acquisition and restructuring costs. -- Represents the cash acquired through the SEMAFO acquisition. -- In Q3-2020, net proceeds of $100 million were received from the La Mancha investment, who exercised its anti-dilution right in support of the SEMAFO acquisition. -- Relates to the reimbursement received from a mining contractor, which was previously capitalized as part of Karma plant expenditures. -- $120 million was drawn on the RCF as a proactive measure in Q1-2020 to secure the Companys liquidity as part of its COVID-19 business continuity program.

NOTES:

-- In Q3-2020, net cash flow from operating activities increased by $144 million compared to Q2-2020 mainly due to the consolidation of the SEMAFO assets, higher gold sales from the Company's existing assets and higher realized gold price which were partially offset by higher royalties, cash costs, taxes and acquisition and restructuring costs. The Q3-2020 figure also includes a $22 million reimbursement received from a mining contractor, which was previously capitalized as part of Karma plant expenditures.Net cash flow from operating activities for YTD-2020 was $385 million, up $204 million compared to YTD-2019. The increase was mainly driven by a $367 million increase in revenues (due to SEMAFO acquisition, Ity CIL commissioning in Q2-2019, and a realized higher gold price), a $6 million decrease in exploration costs, a $10 million decrease in taxes paid, and a $2 million decrease in corporate costs. These items were partially offset by a $91 million increase in cash costs, a $33 million increase in royalty costs, $26 million in acquisition and restructuring costs and a $29 million increase in settlements related to the gold collar. -- Net cash used in investing activities for Q3-2020 included an inflow of $93 million as result of the cash acquired as part of the SEMAFO acquisition, while expenditures on mining interests increased due to the larger portfolio of assets.Net cash used in investing activities for YTD-2020 amounted to $64million, down $148 million compared to YTD-2019, due to a decrease in growth spend as the Ity CIL construction was completed in Q1-2019. Also included in the YTD-2020 number is $12 million of proceeds for the sale of the fleet at Karma and associated spares, as part of the shift to contractor mining, and a $5 million payment for the increased Ity ownership (contingent consideration based on ounces discovered). -- Net cash generated in financing activities for YTD-2020 was $9 million, which is inclusive of the proceeds from the $100 million La Mancha investment as part of the SEMAFO acquisition. In Q1-2020, as a precaution relating to the COVD-19 pandemic, $120 million was drawdown on the RCF, which was repaid in Q3-2020 along with the SEMAFO Macquarie loan facility of $30 million. The YTD-2020 financing activity movement also includes interest payments of $28 million and repayments of $30 million on finance lease obligations. -- At quarter-end, Endeavours liquidity remained strong with $523 million of cash on hand and $120 million undrawn on the RCF. -- The equipment finance lease obligations decreased in Q3-2020 due to scheduled lease payments. -- In 2018, Endeavour issued a $330 million convertible note, maturing in February 2023. -- The $120 million drawdown made in Q1-2020 was reimbursed in Q3-2020. -- Net Debt amounted to $175 million at quarter-end, a decrease of $433 million compared to the corresponding period in 2019. The leverage ratio, Net Debt / Consolidated adj. EBITDA (based on last twelve month), sharply improved over the quarter, decreasing from 1.00 times to 0.29 times. Based on annualizing the Q3 adj. EBITDA, which may be considered as a more relevant metric given that the SEMAFO transaction closed on July 1, 2020, the ratio stands at 0.17 times.

OPERATING CASH FLOW PER SHARE

-- Operating cash flow amounted to a record $202 million in Q3-2020 (or $1.24 per share outstanding), an increase of $144 million compared to Q2-2020 mainly driven by increased production and a higher realized gold price. -- Operating cash flow increased by $204 million in YTD-2020 compared to YTD-2019, amounting to $385million or $3.00 per share in total. Further insights have been provided in Note 18 above.

-- Operating cash flow before non-cash working capital for Q3-2020 amounted to a record $223million (or a record $1.37 per share) in Q3-2020 due to the stronger performance across Endeavour's assets and the accretive nature of the SEMAFO transaction. The increase of $137 million over Q2-2020, is further explained in note 19 above. -- Operating cash flow before non-cash working capital increased by $210 million in YTD-2020 compared to YTD-2019, amounting to $427million or $3.33 per share.

ADJUSTED NET EARNINGS PER SHARE

-- Adjusted Net Earnings attributable to shareholders amounted to $72 million in Q3-2020 (or $0.44 per share), an increase of $20 million compared to Q2-2020 despite a $80 million increase in depreciation (associated to the inclusion of SEMAFO assets and its purchase price allocation) and despite a $66million increase in income tax expense. -- Adjusted Net Earnings attributable to shareholders amounted to $159 million in YTD-2020 (or $1.24 per share), an increase of $122 million compared to YTD-2019 due to the benefit of higher production at a higher realized gold price and the consolidation of the SEMAFO assets. -- Adjustments made in Q3-2020 and YTD-2020 relate mainly to the loss on financial instruments, deferred income tax, share based compensation, and acquisition and restructuring costs.

CAUTIONARY STATEMENT ON FORWARD-LOOKING INFORMATION

This news release contains "forward-looking statements" including but not limited to, statements with respect to Endeavour's plans and operating performance, the estimation of mineral reserves and resources, the timing and amount of estimated future production, costs of future production, future capital expenditures, and the success of exploration activities. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as "expects", "expected", "budgeted", "forecasts", and "anticipates". Forward-looking statements, while based on management's best estimates and assumptions, are subject to risks and uncertainties that may cause actual results to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: risks related to the successful integration of acquisitions; risks related to international operations; risks related to general economic conditions and credit availability, actual results of current exploration activities, unanticipated reclamation expenses; changes in project parameters as plans continue to be refined; fluctuations in prices of metals including gold; fluctuations in foreign currency exchange rates, increases in market prices of mining consumables, possible variations in ore reserves, grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes, title disputes, claims and limitations on insurance coverage and other risks of the mining industry; delays in the completion of development or construction activities, changes in national and local government regulation of mining operations, tax rules and regulations, and political and economic developments in countries in which Endeavour operates. Although Endeavour has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Please refer to Endeavour's most recent Annual Information Form filed under its profile at www.sedar.com for further information respecting the risks affecting Endeavour and its business. AISC, all-in sustaining costs at the mine level, cash costs, operating EBITDA, all-in sustaining margin, free cash flow, net free cash flow, free cash flow per share, net debt, and adjusted earnings are non-GAAP financial performance measures with no standard meaning under IFRS, further discussed in the section Non-GAAP Measures in the most recently filed Management Discussion and Analysis.

The declaration and payment of future dividends and the amount of any such dividends will be subject to the determination of the Board of Directors, in its sole and absolute discretion, taking into account, among other things economic conditions, business performance, financial condition, growth plans, expected capital requirements, compliance with the Company's constating documents, all applicable laws, including the rules and policies of any applicable stock exchange, as well as any contractual restrictions on such dividends, including any agreements entered into with lenders to the Company, and any other factors that the Board of Directors deems appropriate at the relevant time. There can be no assurance that any dividends will be paid at the intended rate or at all in the future.

NON-IFRS MEASURES

Some of the indicators used by Endeavour in this press release represent non-IFRS financial measures. These measures are presented as they can provide useful information to assist investors with their evaluation of the pro forma performance. Since the non-IFRS performance measures presented in the below sections do not have any standardized definition prescribed by IFRS, they may not be comparable to similar measures presented by other companies. Accordingly, they are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The non-IFRS financial performance measures are defined below and reconciled to reported IFRS measures.

Endeavour believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors may find that the total cash cost per ounce sold provided useful information to assist investors with their evaluation of performance and ability to generate cash flow from its operations.

All-in sustaining cost represents the total cash cost plus sustainable capital expenditures and stripping costs presented per ounce sold. Endeavour believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors may find that the all-in sustaining cost per ounce sold better meets their needs by assessing its operating performance and its ability to generate free cash flow.
