Endeavour Silver Announces Q1 2025 Financial Results; Earnings Call at 10AM

PDT (1PM EDT) Today

VANCOUVER, British Columbia, May 13, 2025 -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE:

EXK; TSX: EDR) announces its financial and operating results for the three months ended March 31, 2025. All dollar amounts

are in US dollars ($).

“We’re pleased to report another strong quarter, with production tracking well against plan,” said Dan Dickson, Chief Executive

Officer. “Our revenue performance was bolstered by higher realized prices, highlighting the strength of our portfolio. We

continue to generate solid mine operating cash flow, underpinned by disciplined cost control and a relentless focus on

operational excellence. With robust liquidity, the addition of the Kolpa project, and Terronera coming online soon, we are well

positioned to drive sustainable growth and deliver long-term value for our shareholders.”

Q1 2025 Highlights

• Steady Production in Line with Plan: 1,205,793 ounces (“oz”) of silver and 8,338 oz of gold for 1.9 million oz silver

equivalent (“AgEq”)(1).

• Strong Revenue From Higher Realized Prices : $63.5 million from the sale of 1,223,684 oz of silver and 8,538 oz of

gold at average realized prices of $31.99 per oz silver and $2,903 per oz gold.

• Mine Operating Cash Flow : $8.3 million in operating cash flow before working capital changes(2), a decrease of 18%

from Q1 2024.

• Operating Costs: Cash costs (2) of $15.89 per oz payable silver and all-in sustaining costs(2) of $24.48 per oz, net of

gold credits. Cash costs (2) and all-in sustaining costs were slightly below guidance primarily due to a higher gold by-

product credit.

• Strong Liquidity: Cash position of $64.7 million and working capital(2) of $14.8 million. Cash decreased from

December 31, 2024, as the Company continued investing in development activities at the Terronera project (the

“Terronera Project”).

• Completed Acquisition of Minera Kolpa: Subsequent to the quarter end, the Company completed the acquisition of

Compañía Minera Kolpa S.A. (“Minera Kolpa”) and its main asset, the Huachocolpa Uno Mine (the “Acquisition”) and

concurrently closed the US$35 million copper stream with Versamet Royalties Corporation (See news release dated

May 1, 2025 here).

• Closed the Bought Deal Equity Financing: Subsequent to the quarter end, the Company closed a $50 million bought

deal equity financing, used to fund the cash component of Minera Kolpa, (as announced in the Endeavour news release

dated April 16, 2025 here).

provided at the end of this press release and in the MD&A accompanying the Company’s financial statements, which can be

Direct operating costs per tonne in Q1 2025 increased to $142.72, 6% higher compared with $134.97 in Q1 2024 caused by

6% lower throughput while total direct operating costs remained in line with Q1 2024.

Consolidated cash costs per oz, net of by-product credits, increased 20% to $15.89 driven by 17% lower silver ounces

produced and 8% higher in direct costs, offset by 8% higher by-product gold sales.

All-In-Sustaining Costs (“AISC”) in Q1 2025 was $24.48 per silver ounce, 14% higher than Q1 2024 due to the 17% lower

production of silver ounces, partially offset by an 1% lower cash costs.

In Q1 2025, the Company’s mine operating earnings were $12.8 million (Q1 2024 – $11.7 million) from revenue of $63.5 million

(Q1 2024 – $63.7 million) and cost of sales of $50.7 million (Q1 2024 – $52.1 million). The lower cost of sales were driven by

the 30% lower ounces sold during the period compared to the same period in 2024. Realized silver price was $31.99 per oz for

the quarter, 36% higher than the same period in 2024 and the realized gold price was $2,903 or 37% higher compared to Q1

2025. Higher realized prices have offset the impact of lower ounces sold on revenue. Silver and gold ounces sold decreased

primarily due to the lower production of gold compared to Q1 2024.

In Q1 2025, the Company had operating earnings of $4.0 million (Q1 2024 – $3.3 million) after exploration, evaluation and

development costs of $4.5 million (Q1 2024 – $4.3 million), and general and administrative expense of $4.3 million (Q1 2024 –

$4.0 million). Exploration costs increased during the first quarter as the Company ramped up activities at Pitarrilla.

The loss before taxes for Q1 2025 was $27.8 million (Q1 2024 – earnings of $4.2 million) after loss on derivative contracts of

$31.9 million (Q1 2024 – $nil), a foreign exchange loss of $1.0 million (Q1 2024 – gain of $1.2 million), investment and other

income of $1.5 million (Q1 2024 – investments and other expense of $nil), and finance costs of $0.4 million (Q1 2024 – $0.3

million).

The Company realized a net loss for the period of $32.9 million (Q1 2024 – net loss of $1.2 million) after an income tax

expense of $5.1 million (Q1 2024 – income tax expense of $5.4 million). The deferred tax recovery was realized as a result of

recognizing previously unutilized losses during the period.

Adjusted net loss was $0.2 million in Q1 2025, compared to adjusted earnings of $0.3 million in Q1 2024, while adjusted

earnings per share remained steady at $0.00.

the period ended March 31, 2025, and associated Management’s Discussion and Analysis (“MD&A”) which are available on
