Endeavour Silver Reports Financial Results for the Third Quarter 2021; Earnings Conference Call at 10am PST (1pm EST) Today

VANCOUVER, Nov. 09, 2021 - Endeavour Silver Corp. (NYSE: EXK; TSX: EDR) released its financial results today for the three and nine months ended September 30, 2021. The Company operates two silver-gold mines in Mexico: the Guanacev? mine in Durango state and the Bola?itos mine in Guanajuato state and has recently suspended operations at the El Compas mine in Zacatecas state. All amounts reported are in United States (US) dollars.

Dan Dickson, CEO, commented, "Since our Q2 reporting, our operating costs have decreased to levels that are closer to our 2021 guidance. We continued to withhold metals sales in Q3, which has dampened our financial performance and Q3 earnings. At quarter end, we held over 1 million ounces of silver and 1,200 ounces of gold bullion. We expect to sell this inventory in the coming months, which will ensure a strong finish to the year."

"As of the beginning of November, approximately 90% of our workforce is fully or partially vaccinated. Our operations are running at steady state and we are pleased with the overall performance. Our focus is also on our growth plan, and we have expanded our project development team and commenced preparations for construction at Terronera."

2021 Third Quarter Highlights

• Metal Production: 1,305,399 ounces (oz) of silver and 10,541 oz of gold for 2.1 million oz silver equivalent (AgEq) at an 80:1 silver:gold ratio, totaling 6.1 million AgEq oz for the 9 months ended September 30, 2021.
• Net Revenue: $34.6 million from the sale of 699,539 oz silver and 9,925 oz gold at average realized prices of $24.56 per oz silver and $1,791 per oz gold.

• Earnings: Realized loss of $4.5 million or $0.03 loss per share. The loss is due to the fact that the finished goods inventory was carried at a cost of $18.3 million compared to the estimated fair market value of $29.2 million at quarter end.
• Strong Balance Sheet: Cash position of $101.1 million and working capital $128.7 million.

• Acquired the Bruner Gold Project: A strategic acquisition for an advanced stage exploration property in Nevada, a favorable jurisdiction. The transaction closed on August 31, 2021 for $10.0 million in cash.

Financial Overview (Consolidated Statement of Operations Appended Below)

For the three months ended September 30, 2021, the Company generated net revenue of $34.6 million a decrease of 3% compared to $35.6 million in the same period in 2020 due to withholding metal sales during the quarter, which significantly increased finished goods inventory. Earnings and financial metrics including mine operating cash flows, operating cash flows and EBITDA were also impacted by the increased holding of production inventory.

Gross sales of $35.0 million in Q3, 2021 represented a 3% decrease over the $36.1 million for the same period in 2020.

There was a 6% decrease in silver ounces sold and a 2% decrease in the realized silver price resulting in an 8% decrease to silver sales. There was a 10% increase in gold ounces with an 8% decrease in the realized gold price resulting in a 2% increase in gold sales. During the period, the Company sold 699,539 oz silver and 9,925 oz gold, for realized prices of $24.56 and $1,791 per oz, respectively, compared to sales of 741,262 oz silver and 8,997 oz gold, for realized prices of $25.08 and $1,952 per oz, respectively, in the same period of 2020. For the three months ended September 30, 2021, silver and gold spot prices averaged $24.36 and $1,790 respectively.

The Company significantly increased its finished goods silver and gold inventory to 1,067,404 oz and 3,239 oz, respectively at September 30, 2021 compared to 459,659 oz silver and 2,835 oz gold at June 30, 2021. The cost allocated to these finished goods was $18.3 million at September 30, 2021, compared to $10.1 million at June 30, 2021. At September 30, 2021, the finished goods inventory estimated fair market value was $29.2 million, compared to $17.3 million at June 30, 2021.

After cost of sales of $26.3 million (Q3, 2020 - $29.3 million), mine operating earnings amounted to a $8.3 million (Q3, 2020 -$6.3 million) from mining and milling operations in Mexico. The decrease in cost of sales was primarily related to the 6% decrease in silver ounces sold offset by higher royalty costs, labour costs and additional costs attributed to global supply constraints. Royalties increased 33% from $2.0 million to $2.7 million due to higher production and realized prices and the increased mining of the high grade Porvenir Cuatro extensions at the Guanacev? operation, which are subject to the higher royalty rates.

Excluding depreciation and depletion of $4.8 million (Q3, 2020 - $8.1 million) and stock-based compensation of $0.1 million (Q3, 2020- $0.1 million) mine operating cash flow before taxes was $13.2 million in Q3, 2021 (Q3, 2020 - $15.1 million) with Q3, 2020 also including a write-down of inventory of $0.6 million. Operating earnings were $3.0 million (Q3, 2020 -$0.4 million) after exploration and evaluation expenditures of $4.7 million (Q3, 2020 - $1.7 million), general and administrative expense recovery of $0.5 million (Q3, 2020 - expense of $3.7 million), severance costs of $0.7 million (Q3, 2020 - $Nil) and care and maintenance costs of $0.4 million (Q3, 2020 - $.6 million). The general and administrative expense recovery was primarily due to mark-to-market fluctuations for director's cash settled deferred share units, with a $2.8 million recovery in Q3 2021 versus a $1.5 million expense in Q3, 2020.

Net loss was $4.5 million ($0.03 loss per share) compared to net earnings of $0.5 million (loss of $0.00 per share) in Q3, 2020. Compared to Q3, 2020, the Company increased its investment in exploration and evaluation activities by $3.4 million, experienced a $1.2 million loss in foreign exchange and incurred a $3.0 million unrealized loss on marketable securities.

Current income tax expense increased to $0.7 million (Q32 2020 - $0.6 million) due to increased profitability impacting special mining duty, while deferred income tax expense of $3.0 million was recognized due to the estimated use of loss carry forwards to reduce taxable income primarily at Guanacevi (Q3 2020 - $0.6 million).

Direct operating costs per tonne in Q3, 2021 increased 15%, to $115.57 compared with Q3, 2020 due to higher operating costs at all operations. The operations have seen a strengthening of the Mexican Peso, increased labour costs and, increased third party ore purchased Guanacev? compared to prior year and budgeted. Including royalties and special mining duty, direct costs per tonne increased 16% to $130.38. Royalties increased 33% to $2.7 million as increased production from the El Curso and El Porvenir concessions at Guanacev? with higher prices substantially increasing the royalty expense. The improved profitability increased special mining duty expense to $0.6 million for Q3, 2021 compared to $0.4 million for Q3, 2020.

Consolidated cash costs per ounce, net of by-product credits (a non-IFRS measure and a standard of the Silver Institute) increased to $8.16 due to the increased direct costs per tonne. All-in sustaining costs per ounce (also a non-IFRS measure) remained relatively flat at $17.46. In Q3, 2021 corporate general and administrative included a $2.8 million mark-to-market expense recovery for deferred share units whereas the mark to market expense was $1.5 million in Q3, 2020.
