Endeavour Silver Announces Q4 2024 Financial Results; Earnings Call at 10AM

PDT (1PM EDT) Today

VANCOUVER, British Columbia, March 11, 2025 -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE:

EXK; TSX: EDR) announces its financial and operating results for the three months and the year ended December 31, 2024.

All dollar amounts are in US dollars (US$).

“The Company achieved strong financial results in 2024, maintaining a solid balance sheet," said CEO Dan Dickson. "Higher

realized prices fueled robust revenue, with mine operating cash flow reaching $72.3 million. With the Terronera project nearing

completion and Pitarrilla progressing toward an economic assessment, we are well-positioned for sustained growth and value

creation”.

2024 Highlights

• Production at the Higher end of the Updated 2024 Guidance: Production hit the higher end of the revised guidance

of 7.3 to 7.6 million AgEq oz produced, which had been decreased after a trunnion failure of the primary ball mill at the

Guanacevi mine (see news release from December 17, 2024 here) affected mill throughput from August to December.

Production resumed to full capacity in December with an annual total of 4,471,824 silver ounces (“oz”) and 39,047 gold

oz, for silver equivalent (“AgEq”) production of 7.6 million oz during 2024.

• Strong Revenue from Higher Realized Prices : Revenue of $217.6 million, from the sale of 4,645,574 oz of silver and

38,522 oz of gold at average realized prices of $27.39 per oz silver and $2,397 per oz gold.

• Mine Operating Cash Flow : $72.3 million in mine operating cash flow before taxes (2), compared to $64.4 million in

2023 and operating cash flow before working capital changes of $27.2 million compared to $37.0 million in 2023.

• Net Earnings and Adjusted Earnings : Recognized net loss of $31.5 million compared to net earnings of $6.1 million

and an adjusted net earnings (2) of $8.0 million or earnings (2) of $0.03 per share after excluding loss on derivative

contracts, mark to market of deferred share units, gain on asset disposal, unrealized foreign exchange and investments

losses. This compares to $1.7 million of adjusted net earnings or $0.01 earnings per share in 2023. Adjusted EBITDA (2)

of $52.7 million compared to $47.1 million for 2023.

• Strong Liquidity: Cash position of $106.4 million and working capital(2) of $78.8 million.

• Terronera Nearing Completion: Overall project progress reached 89.4% completion with $302 million of the project’s

budget spent as of December 31, 2024. Wet commissioning is expected in early Q2 2025 (see news release dated

February 7, 2025 here).

• Advancement of the Pitarrilla Project: Advanced exploration and evaluation efforts at Pitarrilla with recent

underground development and drilling. Technical studies commenced in Q4 2024 to support an economic assessment

by Q1 2026. (see news release dated November 13, 2024 here).

Q4 2024 results

Direct operating costs per tonne in Q4 2024 increased by 15% to $152.44 compared with Q4 2023, predominantly caused by

a 35% increase in direct operating costs per tonne at Guanacevi as a result of the temporarily reduced mill throughput.

Consolidated cash costs per silver ounce in Q4 2024, net of by-product credits increased by 9% to $13.68 due to 41% lower

silver ounces produced, offset by 36% lower cash costs. Lower cash costs were mostly driven by 14% higher by-product gold

sales and 7% lower direct costs compared to Q4 2023. Realized gold price was $2,647 per oz for the quarter, 29% higher than

the prior year driving a larger gold credit that is included within cash costs.

All-In-Sustaining Costs (“AISC”) per oz in Q4 2024 increased by 27% to $27.33 compared to Q4 2023 due to the 41% lower

production of silver ounces, partially offset by 36% lower cash costs as discussed above.

In Q4 2024, the Company’s mine operating earnings were $7.7 million (Q4 2023 – $5.4 million) from revenue of $42.2 million

(Q4 2023 – $50.5 million) and cost of sales of $34.5 million (Q4 2023 – $45.1 million). The lower revenue and cost of sales

were driven by 51% lower sales during the period compared to the same period in 2023; in addition to lower production, the

finished goods inventory balance increased during the fourth quarter further reducing sales. Realized silver price was $31.56

per oz for the quarter, 33% higher than the same period in 2023, partially offsetting the impact lower sales on revenue. Royalty

expense was $3.7 million which was 28% lower than $5.1 million in the same period in 2023, due to lower production from the

Guanacevi mine where the royalties are mainly incurred.

In Q4 2024, the Company had an operating loss of $0.5 million (Q4 2023 – operating earnings of $0.2 million) after exploration,

evaluation and development costs of $6.1 million (Q4 2023 – $2.4 million), general and administrative expense of $1.9 million

(Q4 2023 –$2.7 million) and write off of mineral properties of $0.2 million (Q4 2023 – $nil). Exploration activities increased

during the fourth quarter as the Company ramped up its activities at Pitarrilla.

The loss before taxes for Q4 2024 was $1.6 million (Q4 2023 – earnings of $0.7 million) after finance costs of $0.4 million (Q4

2023 – $0.3 million), a foreign exchange gain of $0.4 million (Q4 2023 – $1.4 million) loss on derivative contracts of $1.9 million

(Q4 2023 – $nil) and investment and other income of $0.7 million (Q4 2023 – investments and other expenses of $0.6 million).

The Company realized earnings for the period of $1.0 million (Q4 2023 – net earnings of $3.0 million) after an income tax

recovery of $2.7 million (Q4 2023 – income tax recovery of $2.3 million). The deferred tax recovery was realized as a result of

recognizing previously unutilized losses during the period. In Q4 2024 earnings were impacted by a $0.3 million mark-to-

market adjustment resulting in an unrealized loss on investments (Q4 2023 – unrealized gain of $0.5 million).

Adjusted net earnings were $4.8 million or $0.02 basic adjusted earnings per share in Q4 2024, compared to adjusted

earnings of $3.3 million, or $0.02 basic adjusted earnings per share in Q4 2023.

Full Year 2024 results

For the year ended December 31, 2024, direct operating costs per tonne for the year increased to $140.98, 8% higher than

2023 primarily due to the lower throughput, partially offset by lower direct operating cost. Following the trunnion failure at

Guanacevi, and due to the significant number of variables, estimates and remaining uncertainties, management withdrew its

2024 full year cost guidance in August. With lower operating plant capacity at Guanacevi for approximately four months in

2024, operating costs and all-in sustaining cost metrics were higher than originally guided for 2024.

Consolidated cash costs per oz, net of by-product credits, decreased by 4% to $12.99 in 2024 compared with 2023, driven by

24% lower cash costs and partially offset by 21% lower silver oz produced. Lower cash costs were predominantly caused by

26% higher by-product gold sales. Realized gold price was $2,397 per oz for the year, 22% higher than the prior year driving a

larger gold credit that is included in cash costs.

AISC per oz increased by 4% to $23.88 compared to 2023 driven by the 21% lower production of silver ounces, partially offset

by the 24% lower cash costs as discussed above.

For the year ended December 31, 2024, the Company’s mine operating earnings were $42.1 million (2023 – $36.6 million) on

revenue of $217.6 million (2023 – $205.5 million) with cost of sales of $175.6 million (2023 – $168.9 million). Realized silver

price was $27.39 per oz for the year, 15% higher than the prior year driving higher silver revenues despite fewer ounces sold.

Cost of sales was higher than the prior year, primarily due to the lower economies of scale that arise from lower production,

and the fixed costs incurred during the trunnion failure at Guanacevi. The Company also experienced some inflationary

pressures on costs during the year, yet benefited from the weaker Mexican peso in the second half of the year.

The Company had operating earnings of $8.3 million (2023 – $8.7 million) after exploration, evaluation and development costs

of $19.4 million (2023 – $15.1 million), general and administrative expense of $14.2 million (2023 – $12.3 million) and a write off

of mineral properties of $0.2 million (2023 - $0.4 million). Exploration and evaluation costs were higher than the prior year due

to increased activity at Pitarrilla; development costs were higher than the prior year due to development work at Terronera that

was not eligible for capitalization to the cost of the project.

Loss before tax was $22.0 million (2023 – earnings before tax of $18.3 million) after finance costs of $1.5 million (2023 – $1.4

million), loss on derivative contracts of $30.6 million (2023 – $nil), a foreign exchange loss of $5.5 million (2023 – gain of $4.7

million), a gain on asset disposals of $0.1 million (2023 - $7.1 million) and investment and other income of $7.2 million (2023 –

investment and other expense of $0.8 million). The derivative loss arose on the gold and foreign exchange hedge contracts

which were required to be implemented under the Terronera debt facility. Investment and other income was higher in 2024

compared to 2023 due to interest recovered on VAT refunds in Mexico, as well as a higher cash balance driving greater

interest returns.

The Company realized net loss for the year of $31.5 million (2023 – earnings of $6.2 million) after an income tax expense of

$9.5 million (2023 – $12.1 million).

Adjusted net earnings was $8.0 million or $0.03 basic adjusted earnings per share in 2024, compared to adjusted earnings of

$1.7 million, or $0.01 adjusted net earnings per share in 2023.
