Endeavour Silver Reports Solid 2022 Financial Results: Earnings Conference Call at 9am PST (12pm EST) Time

VANCOUVER, March 02, 2023 - Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE: EXK; TSX: EDR) is pleased to announce its financial and operating results for the year ended December 31, 2022. All dollar amounts are in US dollars (US$).

"Our strong and reliable operating performance resulted in robust 2022 financial results. We are especially pleased to have delivered against our all-in sustaining cost guidance of less than $20 per ounce, despite industrywide inflationary pressures, as a result of our strong production performance. Cost control will continue to be a key focus for the operations group in 2023, as we find pockets of cost moderation and business improvements," stated Dan Dickson, CEO of Endeavour Silver. "As silver prices rebounded in Q4, we were able to take advantage of the higher prices by selling almost half of the year's projected sales towards the end of the year, which resulted in robust cash flow to fund our growth plans."

Mr. Dickson added, "While the market anticipates the official construction decision at Terronera, our funding plan remains intact. We have been advancing development activities with our existing cash, while we confirm a viable debt financing package. We believe that project execution is the correct path for adding long-term value, as we position ourselves as a top silver investment vehicle for investors seeking industry leading growth."

2022 Highlights

• Production Surpassed Guidance: Production of 5,963,445 ounces (oz) of silver and 37,548 oz of gold for 9.0 million oz silver equivalent (AgEq)¹ as compared to upward revised guidance of 7.6-8.0 million oz AgEq.
  

• Strong Revenue: Net revenue of $210.2 million from the sale of 6,464,869 oz of silver and 38,868 oz of gold at average realized prices of $22.07 per oz silver and $1,814 per oz gold.
  

• Costs Per Ounce Relatively In-Line with Guidance, Despite Industry-Wide Inflation: Cash costs⁽²⁾ of $10.65 per oz payable silver were slightly above guidance due to increased labour, power, consumables and royalty costs and all-in sustaining costs ⁽²⁾ of $19.97 per oz is below cost guidance due to the increased silver oz produced.
  

• Healthy Balance Sheet: Cash position of $83.4 million and $93.6 million in working capital⁽²⁾. Cash decreased in the 4^th quarter, as funds were spent on development activities at Terronera.
  

• Increased Cash Flow: $54.0 million in operating cash flow before working capital changes⁽²⁾, and mine operating cash flow before taxes⁽²⁾ of $78.5 million.

• Net Income: Net earnings of $6.2 million, or $0.03 per share, were impacted by inflationary pressures and a reduction in the realized silver price as compared to the prior year.

• Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA)⁽²⁾: Generated EBITDA of $51.9 million, 6% decrease from prior year due to the lower realized silver prices offset by the increased production.
  

• Construction Preparation Advances at the Terronera Project: Progress on development activities include onsite delivery of mobile mining equipment, procurement of major equipment, and assembly of initial project infrastructure such as the temporary mine maintenance shop and a permanent camp facility. Earthworks included site clearing, road upgrades and underground mine access development.
  

• Financial Due Diligence Continues on Financing the Terronera Project: The Company intends to make a formal construction decision subject to completion of a financing package and receipt of additional amended permits in the coming months.
  

• Published Initial Mineral Resource Estimate for the Pitarrilla Project: One of the world's largest undeveloped silver projects, Pitarrilla will form the cornerstone of the Company's growth profile, together with Terronera and Parral (see News Release dated December 8, 2022).

For the year ended December 31, 2022, net revenue, net of $3.0 million of smelting and refining costs, increased by 27% to $210.2 million (2021: $165.3 million).

Gross sales of $213.2 million in 2022 represented a 27% increase over the $167.3 million in 2021. Silver oz sold increased by 68% with a 12% decrease in the realized silver price, resulting in a 47% increase in silver sales. Gold oz sold increased by 1% with a 1% increase in the realized gold price, resulting in a 1% increase in gold sales. During the period, the Company sold 6,464,869 oz silver and 38,868 oz gold for realized prices of $22.07 and $1,814 per oz, respectively, compared to sales of 3,856,883 oz silver and 39,113 oz gold for realized prices of $25.22 and $1,790 per oz, respectively, in 2021. In 2022, silver and gold London spot prices averaged $21.73 and $1,800, respectively.

The Company significantly decreased its finished goods silver and gold inventory to 530,250 oz and 1,707 oz, respectively, at December 31, 2022 compared to 1,082,610 oz silver and 3,674 oz gold at December 31, 2021. The cost allocated to these finished goods was $6.1 million at December 31, 2022 compared to $15.6 million at December 31, 2021. At December 31, 2022, the finished goods inventory fair market value was $15.8 million, compared to $31.7 million at December 31, 2021. Earnings and other financial metrics, including mine operating cash flow⁽²⁾, operating cash flow⁽²⁾ and EBITDA⁽²⁾ were positively impacted by the decreased bullion inventory held at year end.

After cost of sales of $158.6 million (2021 - $128.9 million), an increase of 23%, mine operating earnings were $51.5 million (2021- $36.4 million). The increase in cost of sales was due to increased production, labour, power and consumables costs and significantly higher royalty costs. Cost of sales was also impacted by the increase in ounces sold during 2022, as the Company held less inventory at the end of 2022 than at the end of 2021. Royalties increased 29% to $17.8 million due to increased mining of the high-grade Porvenir and Porvenir Cuatro extensions at the Guanaceví operation, which are subject to higher royalty rates. During 2022 the Company's operations experienced higher than budgeted costs due to global supply constraints, inflationary pressure, materials shortages, labour costs tracking higher than planned and increased purchased ore at the Guanaceví operation.

The Company had operating earnings of $23.5 million (2021: $22.3 million) after exploration and evaluation costs of $16.2 million (2021: $17.9 million), general and administrative costs of $10.6 million (2021: $10.1 million), care and maintenance cost of $0.6 million (2021: $1.3 million), and a write-off of exploration properties of $0.7 million (2021: $0.7 million). In 2021, there was also an impairment reversal of $16.8 million, resulting from the valuation assessment performed for the El Cubo mine and related assets upon classification as held for sale, and severance cost of $0.7 million.

Earnings before income taxes were $25.0 million (2021: $29.7 million) after finance costs of $1.3 million (2021: $1.0 million), a foreign exchange gain of $1.9 million (2021: loss of $1.1 million), a net gain on disposal of assets of $2.5 million primarily generated by the gain on the sale of the El Compas mine of $2.7 million (2021: gain on the sale of El Cubo mine and assets of $5.8 million) and investment and other expense of $1.6 million (2021: investment and other income of $3.7 million).

The Company realized net earnings for the period of $6.2 million (2021: $14.0 million) after an income tax expense of $18.8 million (2021: $15.7 million). Current income tax expense increased to $6.4 million (2021 - $3.5 million) due to increased profitability of the Guanacevi mine impacting both the current income tax and the special mining duty, while deferred income tax expense of $12.4 million is primarily due to the estimated use of loss carryforwards to reduce taxable income at Guanacevi (2021 - $12.2 million)

Direct operating costs⁽²⁾ on a per tonne basis increased to $130.80, up 13% compared with 2021 due to higher operating costs at Guanaceví and Bolañitos and a 6% decrease in processed tonnes. Guanaceví and Bolañitos have seen increased labour, power and consumables costs primarily driven by inflationary pressure and at Guanaceví, third party ore purchased and operating development have increased compared to the prior year. Direct costs per tonne ⁽²⁾ increased to $155.63, up 16% compared to 2021 due to the increase in direct operating costs as well as the increase in royalty costs.

Consolidated cash costs per oz, net of by-product credits, increased to $10.65 primarily due to the higher direct costs per tonne partially offset by increased silver production due to increased silver grades. All-in sustaining costs decreased 2% to $19.97 per oz in 2022 due to the higher cash costs and a moderate increase in capital expenditures being allocated over the increased silver ozs produced. Actual cash cost metrics were slightly higher than 2022 cost guidance primarily due to the increased costs relating to labour, power, consumables, increased third party ore purchases, higher royalties and special mining duty offset by the higher ore grades mined at Guanacevi.
