Endeavour Silver Produces 942,274 oz Silver and 10,260 oz Gold (1.8 Million oz Silver Eq.) in Third Quarter, 2020; Hosting Video Zoom Update on October 13, 2020

Endeavour operates three high grade, underground, silver-gold mines in Mexico; Guanacevi in Durango state, Bolanitos in Guanajuato state and El Compas in Zacatecas state. Production returned to plan in Q3, notwithstanding a heavy rain season, after a two month shut down in Q2 following a government mandated suspension of mining operations due to COVID-19.

Bradford Cooke, Endeavour CEO, commented, “After riding out a challenging Q2 with our mining operations suspended for more than half the quarter, due to the government COVID-19 mandate, our operations team were able to deliver a return to our production plan in Q3, 2020. I commend all of our employees for quickly and fully embracing our COVID-19 precautionary measures to prevent contagion at our mine sites.”

“This pandemic has temporarily changed our lives and required all of us to be persistent with our safety procedures to operate as safely and effectively as possible. We continue to keep our higher risk people safe at home during this period and yet our mines are running near capacity despite having fewer employees on site, a testament to the positive response by our operations management and employees.”

2020 Third Quarter Highlights

• Consolidated Silver Equivalent Production Continues to Improve Q-o-Q: Production was up 66% compared to Q2, 2020 due to the resumption of normal throughput.
• GuanaceviGrades Continue to Outperform: Silver and gold grades continued to deliver well above plan however throughput was affected by significant rainfall in August and September. Over 24,000 tonnes of ore was stockpiled at the plant during the quarter. Management anticipates reaching 1,200 tpd in Q4, while reviewing alternatives to better manage next year’s rainy season.
• BolanitosPerformance Continues to Improve: Throughput approached 1,075 tpd while gold grades aligned with plan and silver grades remain lower than plan. Output from San Miguel is expected to increase in Q4, 2020 as mine development is completed and grades will rise.
• El Compas Performance Remains Steady: Throughput at 260 tpd remains steady while gold grades were similar to plan, but silver grades remain lower than plan. Brownfield exploration re-started in the quarter and will continue through Q4, 2020.
• Metal Sales and Inventories: Sold 741,263 oz silver and 8,998 oz gold, held 412,913 oz silver and 1,963 oz gold of bullion inventory and 13,761 oz silver and 1,032 oz gold in concentrate inventory. The Company’s improved balance sheet provided management with the flexibility to withhold metal from sale during the price correction over last two weeks of September. Management expects to sell a significant portion of the metal inventory in anticipation of a precious metal prices rebound in Q4, 2020.
• Robust Economics in the Updated 2020 Pre-Feasibility Study on the Terronera Mine Project: Represents the Company’s next core asset with a low CAPEX and low operating costs, short payback period and exceptional financial returns. See EDR news release dated July 14, 2020 or the accompanying webinar slides here.
• Strengthening Management Team with Newly Appointed Chief Operating Officer: Mr. Gray brings over 40 years experience in mine engineering and operations, including strategic planning, budget oversight, economic evaluations and corporate development. He has been responsible for designing, financing, constructing and operating large precious metal mines along with all related sustainability programs including health, safety, environmental, community, security and labour, and corporate responsibilities with stakeholders.
• AdvancingTerronera: Awarded Feasibility Study contract to Wood Plc, for completion in the summer of 2021.
• Filed At-The-Market Prospectus Supplement for up to $60 million: Proceeds to be used for funding growth initiatives including advancing Terronera, Parral and prospective mergers and acquisitions and working capital purposes.

2020 Third Quarter MiningOperations

Consolidated silver production in Q3, 2020 was lower than Q3, 2019 due to lower silver grades from the Bolañitos and El Compas mines, and the November 2019 suspension of El Cubo operations, offset by a significant increase in silver grade ore at the Guanacevi mine. Consolidated gold production increased 6% due to higher throughputs and gold grade ore from the Bolañitos and Guanacevi mines, offset by lower grades from El Compas and the November 2019 suspension of the El Cubo operations.

Guanacevi silver and gold grades were both significantly higher than Q3, 2019 and well above plan. Mining the new, higher grade El Curso, Milache and SCS orebodies has led to the significantly improved ore grades. Mine output approached plan in Q3, 2020, however an extremely wet August and September impacted the plant throughput during the quarter. The mine added over 24,000 tonnes of ore to the plant stockpile in Q3, 2020 and as the rain subsides, management expects throughput to reach the plant capacity of 1,200 tpd by quarter-end. Management is reviewing alternatives to reduce the impact of rain on future plant throughput.

Bolanitos gold grades were higher and silver grades were lower than Q3, 2019. The Q2, 2020 mine re-start focused on accelerated mine development and additional dilution control in order to return to plan in Q3, 2020. Mine output and plant throughput approached plan and is expected to maintain these levels going forward. Silver grades remain lower than plan due to lower mine output from the San Miguel vein which has higher silver and gold grades than other working areas. The output from San Miguel vein is expected to increase in Q4, 2020 as development is completed. Mine development will continue to focus on completing access to the San Miguel ore body and commencing access to the Medallito discovery.

El Compas throughput was above plan, however dilution remains a continuing focus at the mine. El Compas grades were lower than Q3, 2019, and below planned grade. The variation of grades was due to dilution and normal fluctuations in the ore body.
