Endeavour Silver Announces Q1 2023 Financial Results; Earnings Call at 10AM PDT Today

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

"We are pleased to report a solid start this year with consolidated production expected to meet full year guidance," stated Dan Dickson, CEO of Endeavour Silver. "Guanacevi continues to perform well, generating strong operating cash flow which we are reinvesting in the business. Industry-wide inflation pressures continue to persist, which combined with a strengthening Mexican Peso, are increasing our operating costs. We are working to manage our inputs in order to offset these cost pressures as we pursue productivity and efficiency initiatives.

Added Mr. Dickson, "On April 18, 2023, we reached a key milestone with the announcement of the project financing commitment of $120 million and a subsequent formal construction decision at Terronera. The successful execution of this underground mine development and mill is integral to achieving our growth goal to nearly double our production by 2025 and transform our cost profile. With a seasoned team of development personnel, we are moving forward confidently and look forward to establishing an exciting future for our stakeholders."

Q1 2023 Highlights

Financial Overview (see appendix for consolidated financial statements)

^{( 1 )} Silver equivalent (AgEq) is calculated using an 80:1 silver:gold ratio.

⁽²⁾ These are non-IFRS financial measures and ratios. Further details on these non-IFRS financial measures and ratios are provided at the end of this press release and in the MD&A accompanying the Company's financial statements, which can be viewed on the Company's website, on SEDAR at www.sedar.com and on EDGAR at www.sec.gov .

For the three months ended March 31, 2023, revenue, net of $0.6 million of smelting and refining costs, decreased by 4% to $55.5 million (Q1 2022: $57.7 million).

Gross sales of $56.1 million in Q1 2023 represented a 4% decrease over the $58.4 million in Q1 2022. Silver oz sold decreased by 3%, due to a decrease in finished goods silver ounces available for sale as at December 31, 2022 compared to December 31, 2021, offset by increased silver production.   There was a 5% decrease in the realized silver price, resulting in an 8% decrease in proceeds from silver sales. Gold oz sold increased by 9% with a 3% decrease in the realized gold price, resulting in a 6% increase in proceeds from gold sales. During the period, the Company sold 1,667,408 oz silver and 9,126 oz gold for realized prices of $23.16 and $1,917 per oz, respectively, compared to Q1 2022 sales of 1,717,768 oz silver and 8,381 oz gold for realized prices of $24.38 and $1,970 per oz, respectively. In Q1 2023, London spot prices for silver and gold averaged $22.55 and $1,890, respectively.

The Company slightly decreased its finished goods silver inventory and slightly increased its finished goods gold inventory to 471,069 oz and 1,766 oz, respectively, at March 31, 2023 compared to 530,250 oz silver and 1,707 oz gold at December 31, 2022. The cost allocated to these finished goods was $7.4 million at March 31, 2023 compared to $6.1 million at December 31, 2022. At March 31, 2023, the finished goods inventory fair market value was $14.7 million, compared to $15.8 million at December 31, 2022.

After cost of sales of $39.54 million (Q1 2022 - $37.4 million), an increase of 6%, mine operating earnings were $16.0 million (Q1 2022 - $20.3 million). The cost of sales in Q1, 2023 was impacted by a strengthened Mexican peso, higher labour, power and consumables costs as the Company, as well as the industry, has experienced significant inflationary pressures. The Company also recognized increased royalty costs during Q1, 2023 compared to the prior period as a higher percentage of the production at Guanacevi has come from the El Curso and El Porvenir concessions, which are subject to royalties.

The Company had operating earnings of $6.9 million (Q1 2022: $12.6 million) after exploration and evaluation costs of $4.2 million (Q1 2022: $3.2 million) and general and administrative costs of $4.9 million (Q1 2022: $4.3 million. Exploration and evaluation costs increased primarily to additional spending on the recently acquired Pitarrilla project and general and administrative costs increased primarily due to investment in a new ERP system.

Earnings before income taxes were $12.5 million (Q1 2022: $18.9 million) after finance costs of $0.4 million (Q1 2022: $0.3 million), a foreign exchange gain of $1.9 million (Q1 2022: $0.8 million), and investment and other income of $4.0 million (Q1 2022: $5.8 million). The increase in the foreign exchange gain is due to the strengthening of the Mexican peso which increases the value of peso denominated working capital items. The investment and other income during Q1 2023 primarily resulted from an unrealized gain on marketable securities and warrants of $3.1 million (Q1 2022: $5.4 million).

The Company realized net earnings for the period of $6.5 million (Q1 2022: $11.7 million) after an income tax expense of $6.1 million (Q1 2022: $7.2 million).   Current income tax expense increased to $4.4 million (Q1 2022 - $1.0 million) and deferred income taxes decreased to $1.7 million (Q1, 2022: $6.2 million).During 2022, the changes in current and deferred taxes were driven primarily by the utilization of loss carryforwards at Guanacevi and during 2023 there were no further loss carryforwards available to offset against current income tax and changes in deferred income taxes was primarily derived from changes in temporary timing differences between deductions for accounting versus deductions for tax.

Direct operating costs ^{( 2)} on a per tonne basis increased to $132.11, up 8% compared with Q1 2022 due to both a strengthening of the Mexican peso and higher operating costs at both Guanaceví and Bolanitos from increased inflationary pressure during 2022 and Q1 2023. As the Mexican peso strengthens, the Company's Mexican peso denominated costs are increased in US dollar terms. Guanaceví and Bolañitos have seen increased labour, power and consumable costs.

Consolidated cash costs per oz, net of by-product credits, increased to $11.12 primarily due to the higher direct costs per tonne slightly offset by a higher gold credit driven by higher gold production compared to Q1 2022. AISC decreased by 4% on a per oz basis compared to Q1 2022 as a result of costs being allocated over increased ounces produced which offset the increased costs.
