Endeavour Silver Reports 2023 Financial Results: Earnings Conference Call at 9am PST (12pm EST) Time

VANCOUVER, British Columbia, March 11, 2024 (GLOBE NEWSWIRE) — Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) announces its financial and operating results for the fourth quarter and year ended December 31, 2023. All dollar amounts are in US dollars (US$).

“The path to growth is never a straight line, so our ability to rise above challenges defines our success. During 2023, we kept focused on our main goals, while successfully navigating industry challenges” commented Dan Dickson, CEO of Endeavour Silver. “From a cost perspective, all Mexican miners faced overarching challenges, with persistent cost pressures across various channels. Our operations team demonstrated their resolve to overcome a significant challenge at Guanacevi, by elevating both mine and mill productivity levels above planned targets. As the remediation efforts extended into early Q4, the positive momentum from these initiatives reduced Q4 2023 cost metrics compared to Q3 2023 and will carry forward into the upcoming year.”

Mr. Dickson added, “With operating costs at their peak, we remain focused on cost discipline to offset inflationary and foreign exchange pressures while improving productivity. Bringing Terronera into production in late 2024 will provide the base we need for significant production growth and margin expansion as we move down the cost curve. We believe that project execution is our pathway to adding long-term value, as we position ourselves as a top silver investment vehicle for investors seeking industry leading growth.”

2023 Financial Highlights

• Production In-Line with Guidance: Consolidated production of 5,672,703 silver ounces (oz) and 37,858 gold oz for silver equivalent ⁽¹⁾ production of 8.7 million oz, representing the Company’s third consecutive year of meeting or exceeding production guidance.
• Revenue: Revenue of $205.5 million from the sale of 5,669,760 oz of silver and 37,186 oz of gold at average realized prices of $23.76 per oz silver and $1,968 per oz gold.
• Multiple Items Resulted in Escalated Annual Costs; Significant Improvement in Q4: Cash costs⁽²⁾ of $13.49 per oz payable silver were above guidance due to a strengthened Mexican Peso, inflationary pressures and lower production and All-in Sustaining Costs ⁽²⁾ of $22.93 per oz were above guidance due to the aforementioned higher costs. Fourth quarter cash costs⁽²⁾ of $12.54 per oz payable silver and all-in sustaining costs ⁽²⁾ of $21.48 signal visible improvement from third quarter costs due to remedial measures implemented at Guanacevi, as productivity improved.
• Healthy Balance Sheet: Cash position of $35.3 million and $42.5 million in working capital⁽²⁾. Cash decreased in Q4, as funds were spent on development activities at Terronera. During Q4, the Company raised gross proceeds of $39.3 million through issuances, primarily to fund the activities at Terronera.
• Cash Flow: $37.0 million in operating cash flow before working capital changes⁽²⁾, and mine operating cash flow before taxes⁽²⁾ of $64.4 million.

• Net Income: Net earnings of $6.1 million, or $0.03 per share, were impacted by inflationary pressures, foreign exchange and higher realized metal prices compared to the prior year.
• Construction Continues on Schedule at the Terronera Mine: Concrete work is well advanced and erection of steel for the grinding and flotation areas has started at year end (see news release dated February 12, 2024). Overall project progress reached 43% and the project remains on track for commissioning in Q4 2024.

Year Ended December 31, 2023

For the year ended December 31, 2023, revenue, net of $2.4 million of smelting and refining costs, decreased by 2% to $205.5 million (2022: $210.2 million).

The decrease in revenue is attributed to lower production compared to 2022 but was partially offset by higher precious metal prices realized during the year. During the period, the Company sold 5,669,760 oz silver and 37,186 oz gold for realized prices of $23.76 and $1,968 per oz, respectively, compared to sales of 6,464,869 oz silver and 38,868 oz gold for realized prices of $22.07 and $1,814 per oz, respectively, in 2022.

After cost of sales of $168.9 million (2022: $158.6 million), an increase of 6%, mine operating earnings were $36.6 million (2022: $51.5 million). The increase in cost of sales, despite lower sales, was due to higher costs as a result of inflation on a number of direct inputs, the impact of the appreciation of the Mexican peso on labour costs and direct inputs and higher royalty costs. Royalties increased 25% to $22.2 million (2022: $17.8 million) due to increased mining of the high-grade El Curso and El Porvenir extensions at the Guanaceví operation, which are subject to significant royalty rates.

The Company had operating earnings of $8.7 million (2022: $23.5 million) after exploration, evaluation and development costs of $15.1 million (2022: $16.2 million), general and administrative costs of $12.4 million (2022: $10.6 million), and a write-off of exploration properties of $0.4 million (2022: $0.7 million). In 2022, there were also care and maintenance costs of $0.6 million related to the El Compas mine which was sold in late 2022.

Earnings before income taxes were $18.2 million (2022: $25.0 million) after finance costs of $1.4 million (2022: $1.3 million), a foreign exchange gain of $4.7 million (2022: $1.9 million), a net gain on disposal of assets of $7.1 million primarily generated by the gain on the sale of the Cozamin royalty (2022: $2.5 million primarily from the gain on the sale of El Compas mine) and investment and other expense of $0.8 million (2022: $1.6 million).

The Company realized net earnings for 2023 of $6.1 million (2022: $6.2 million) after a tax expense of $12.1 million (2022: $18.7 million). Current income tax expense increased to $11.3 million (2022: $6.4 million) while deferred income tax expense decreased to $0.8 million (2022: $12.4 million) The deferred income tax expense of $0.8 million is derived from changes in temporary timing differences between deductions for accounting versus deductions for tax. During 2022, the changes in deferred taxes were driven primarily by the utilization of loss carryforwards at Guanacevi with no further loss carryforwards available to offset against current income tax in 2023.

Direct operating costs⁽²⁾ on a per tonne basis increased to $141.72, up 8% compared with 2022 due to higher operating costs. Guanaceví and Bolañitos have seen increased labour, power and consumables costs primarily driven by inflationary pressure as well as the impact of a strengthened Mexican Peso. Direct costs per tonne ⁽²⁾ increased to $171.00, up 10% compared to 2022 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 $13.49 primarily due to the higher direct costs per tonne and a reduction in production partially offset by higher gold credits. All-in sustaining costs increased 15% to $22.93 per oz in 2023 due to the higher cash costs, an increase in allocated general and administrative expenses partially offset by a decrease in capital expenditures.

Consolidated cash costs per oz, net of by-product credits of $13.49 exceeded cash cost guidance of between a $10.00 and $11.00 range, primarily due to higher direct costs which were impacted by a strengthened Mexican Peso and higher inflationary pressure than anticipated. Cash costs, on a per ounce basis, were also impacted by realized production being on the lower end of guidance. All-In-Sustaining Costs (“AISC”) of $22.93 on a per oz basis was above guidance of $19.00 to $20.00 per ounce and similarly impacted by the increased costs.
