Endeavour Silver Reports Financial Results for the Second Quarter 2021; Earnings Conference Call at 10am PDT (1pm EDT) Today

VANCOUVER, Aug. 10, 2021 - Endeavour Silver Corp. (NYSE: EXK; TSX: EDR) released its financial results today for the three and six months ended June 30, 2021. The Company operates three silver-gold mines in Mexico: the Guanacev? mine in Durango state, the Bola?itos mine in Guanajuato state and the El Compas mine in Zacatecas state. All amounts reported are in United States (US) dollars.

Dan Dickson, CEO, commented, "From a financial standpoint, our Q2 performance was stronger than the respective period last year, as revenue, cash flow and earnings were all higher. However, our operating costs are clearly not where we want them to be. We are working to optimize our operating cost profile in the second half of 2021."

"This month, we plan to suspend operations at El Compas due to exhaustion of reserves. This small asset represents less than 5% of 2021 consolidated production and will not affect our progress towards attaining or surpassing our production guidance for the year. Our remaining production platform at Guanacevi and Bola?itos is strong and sustainable with excellent brownfield exploration opportunities."

"We are pleased to enter the second half of the year with a robust cash balance of $125 million and a clean balance sheet ahead of a potential construction decision for Terronera later this year. We will be completing the Feasibility Study during Q3 with a construction decision anticipated shortly thereafter."

2021 Second Quarter Highlights

• Metal Production: Produced 1,073,724 ounces (oz) silver, up 80% and 11,166 oz gold, up 92%, in-line with guidance for 2.0 million oz silver equivalent (AgEq), up 85%, at an 80:1 silver:gold ratio, compared to Q2, 2020 when operations were suspended due to COVID-19 for a portion of the period.
• Net Revenue: Totaled $47.7 million, up 136%, from the sale of 1,120,266 oz silver and 9,810 oz gold at average realized prices of $26.82 per oz silver and $1,866 per oz gold. Management withheld metal sales in Q1, 2021 and continues to carry higher metal inventory totaling 459,659 oz silver and 1,891 oz gold of bullion inventory and 12,159 oz silver and 944 oz gold in concentrate inventory.
• Operating Costs: Cash cost⁽¹⁾ $13.03 per oz payable silver, up 369% year-on-year and all-in sustaining cost (AISC)⁽¹⁾ $25.39 per oz payable silver, up 70% year-on-year, net of gold credits. Operating costs were higher than budgeted due to global supply chain constraints creating inflationary pressures, increased labor costs, a strengthening Mexican Peso and increased operating development at Guanacevi.
• Cash Flow: $8.7 million in cash flow from operations before working capital changes, up 358% compared to Q2, 2020. The Company continued to hold significant finished goods, increased deposits for equipment purchases, invested in exploration activities and advanced the Terronera Feasibility Study.
• Earnings: Realized earnings of $6.7 million or $0.04 per share, up sharply compared to a loss of $3.3 million in Q2, 2020 due to increased mine operating earnings, the gain on the sale of the El Cubo asset and gain on the sale of marketable securities, offset by increased exploration and evaluation activities, higher general and administrative costs and higher tax expense. Excluding the gain on sale of the El Cubo asset, the adjusted earnings are $0.8 million. At quarter end, the finished golds inventory was carried at a cost of $10.1 million compared to the fair market value of $17.3 million.
  

• Strong Balance Sheet: Cash position $125.2 million and working capital $146.8 million. Raised $28.4 million in equity financing through an ATM facility, net of issuance costs. Only remaining term liabilities are equipment loans of $7.8 million.
  

• Completed the Sale of El Cubo: The transaction closed on April 9, 2021 for $19.8 million in cash and share payments with up to $3 million in contingent payments payable by Guanajuato Silver (previously Vangold Mining Corp).
  

Subsequent to the End of the Second Quarter 2021:

• Suspension of Operations at El Compas: The Company has decided to suspend mining and milling operations at El Compas in August. Mining assets and key talent will be transferred within the Company to Bola?itos and Terronera. The associated suspension costs are estimated to be $1.3 million, including $1.0 million in severance, to be incurred over the remainder of the year. Management is currently evaluating its alternatives for the assets.
• Agreement to Acquire Bruner Gold Project from Canamex: strategic acquisition opportunity for an advanced stage exploration property in a favorable jurisdiction for $10 million in cash. The agreement is subject to Canamex shareholder approval in Q3 (see EDR news release dated July 19, 2021).

Financial Overview

In Q2 2021, net revenue increased 136% to $47.7 million as a result of higher metal prices and increased production. Mine operating cash flows, operating cash flows and EBITDA increased significantly compared to Q2, 2020. For a period in Q2, 2020, the mine operations were suspended due to government decree to stop the spread of COVID-19.

The Company recognized earnings of $6.7 million compared to a loss of $3.3 million in Q2, 2020. A gain of $5.8 million was recognized on the sale of the El Cubo mine and related assets and liabilities.

Cost of sales for Q2, 2021 was $37.5 million, an increase of 109% over the cost of sales of $17.1 million for the same period of 2020. The increase in cost of sales was primarily related to the 76% increase in silver ounces sold, significantly higher royalty costs, labour costs and additional costs attributed to global supply constraints. Royalties increased 438% from $0.8 million to $4.3 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 significantly higher royalty rates.

The Company slightly decreased its finished goods silver and increased its finished goods gold inventory to 459,659oz and 1,891 oz, respectively at June 30, 2021 compared to 529,817 oz silver and 1,689 oz gold at March 31, 2021. The cost allocated to these finished goods was $10.1 million at June 30, 2021, compared to $8.0 million at March 31, 2021. At June 30, 2021, the finished goods inventory fair market value was $17.3 million, compared to $15.9 million at March 31, 2021.

Financial Results (Consolidated Statement of Operations Appended Below)

For the period ended June 30, 2021, the Company generated net revenue of $47.7 million an increase of 136% compared to $20.2 million. Gross sales of $48.3 million in Q2, 2021 represented a 136% increase over the $20.5 million for the same period in 2020. There was a 76% increase in silver ounces sold and a 57% increase in the realized silver price resulting in a 179% increase to silver sales. Similarly, there was an 88% increase in gold ounces sold at prices similar to the prior year resulting in an 88% increase in gold sales. During the period, the Company sold 1,120,266 oz silver and 9,810 oz gold, for realized prices of $26.82 and $1,866 per oz, respectively, compared to sales of 634,839 oz silver and 5,218 oz gold, for realized prices of $17.04 and $1,862 per oz, respectively, in the same period of 2020. For the three months ended June 30, 2021, silver and gold spot prices averaged $26.69 and $1,816, respectively.

After cost of sales of $37.5 million (Q2, 2020 - $17.1 million), mine operating earnings amounted to a $10.2 million (Q2, 2020 -$3.1 million) from mining and milling operations in Mexico.

Excluding depreciation and depletion of $6.6 million (Q2, 2020 - $3.9 million), stock-based compensation of $0.1 million (Q2, 2020- $0.1 million) and a write-down of inventory of $0.3 million (Q2, 2020 - $0.5 million), mine operating cash flow before taxes was $17.2 million in Q2, 2021 (Q2, 2020 - $7.6 million). Operating earnings were $0.8 million (Q2, 2020 - loss of $4.6 million) after exploration and evaluation expenditures of $5.0 million (Q2, 2020 - $1.7 million), general and administrative expense of $4.3 million (Q2, 2020 - $3.1 million) and care and maintenance costs of $0.1 million (Q2, 2020 - $2.9 million).

Net earnings amounted to $6.7 million ($0.04 per share) compared to a net loss of $3.3 million (loss of $0.02 per share) in Q2, 2020.

Current income tax expense increased to $2.2 million (Q2 2020 - $0.2 million) due to increased profitability impacting special mining duty, while deferred income tax expense of $1.1 million was recognized due to the estimated use of loss carry forwards to reduce taxable income at Guanacevi (Q2 2020 - $0.5 million deferred income tax recovery).

Direct operating costs per tonne in Q2, 2021 increased 18%, to $119.94 compared with Q2, 2020 due to higher operating costs at all operations. The operations have seen a strengthening of the Mexican Peso, increased labour costs, increased third party ore purchased and increased operating development at Guanacev? compared to prior year and budgeted. Including royalties and special mining duty, direct costs per tonne increased 29% to $141.61. Royalties increase 1,781% to $4.3 million as increased production from the El Curso and El Porvenir concessions at Guanacev? with higher prices substantially increased the royalty expense. The improved profitability increased special mining duty expense to $0.9 million for Q2, 2021, which was negligible in Q2, 2020.

Consolidated cash costs per ounce, net of by-product credits (a non-IFRS measure and a standard of the Silver Institute) increased to $13.03 due to the increased direct costs per tonne. All-in sustaining costs (also a non-IFRS measure) increased to $25.39 per ounce in Q2, 2021 as a result of higher corporate general and administrative costs, increased mine site expensed exploration and increased capital expenditures at Guanacev? to accelerate mine development within the El Curso ore body. In Q2, 2021 corporate general and administrative included a $1.6 million mark to market expense of deferred share units expense whereas the mark to market expense was $1.1 million in Q2, 2020.
