VANCOUVER, Nov. 05, 2024 - Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE: EXK; TSX: EDR) announces its financial and operating results for the three and nine months ended September 30, 2024. All dollar amounts are in US dollars (US$).

"Q3 2024 presented its share of challenges as the Company operated at reduced capacity due to the trunnion failure at the Guanaceví mine," said Dan Dickson, Chief Executive Officer. "While we are eager to return to full production at Guanaceví, we are most excited to be in the final sprint towards commissioning at the Terronera project, which promises to be a transformative milestone for the Company."

Q3 2024 Highlights

• Production tracking toward the updated 2024 production guidance: Production decreased in August and September due to a trunnion failure of the primary ball mill at the Guanaceví mine (see news release from August 12, 2024). Q3 production of 874,717 silver ounces (oz) and 9,290 gold oz, for silver equivalent ("AgEq") production of 1.6 million oz.
• Strong Revenue from Higher Realized Prices: $53.4 million from the sale of 1,017,392 oz of silver and 9,412 oz of gold at average realized prices of $29.63 per oz silver and $2,528 per oz gold.
• Mine Operating Cash Flow: $19.6 million in mine operating cash flow before taxes⁽²⁾, compared to $10.6 million in Q3 2023 and operating cash flow before working capital changes of $4.5 million compared to $3.3 million in Q3 2023.
• Adjusted Earnings: Recognized an adjusted income of $1.6 million or earnings of $0.01 per share after excluding loss on derivative contracts, mark to market deferred share units, unrealized foreign exchange and investments losses.
• Healthy Balance Sheet: Cash position of $54.9 million and working capital⁽²⁾ of $29.4 million.
• Drawdown on Terronera Senior Secured Debt Facility: During the third quarter of 2024 the Company completed drawdowns of $25 million from the senior secured debt facility. Subsequent to the end of Q3, the Company completed a final drawdown of $35 million.
• Construction Continues on Schedule at the Terronera Mine: Overall project progress reached 77% completion, with more than $258 million of the project's budget spent to date. Project commitments total $270 million, which is 99% of the $271 million capital budget, and remains on track for commissioning near the end of Q4 2024. (see news release dated October 21, 2024).
  

Operating And Financial Overview

⁽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.sedarplus.ca and on EDGAR at www.sec.gov.

In Q3 2024, direct operating costs per tonne increased to $138.54, 2% higher than Q3 2023. The increase in the cost per tonne compared to the prior period was due to 18% lower tonnes processed, predominantly caused by the temporarily reduced capacity at Guanaceví. Effective in September, the Company ceased contract mining activities and local third-party material purchases to lessen the impact of lower throughput on direct operating costs and cash flow.

Consolidated cash costs per silver ounce, net of by-product credits, is $11.35 per silver ounce, a 37% decrease compared with $17.94 per silver ounce in Q3 2023, driven by a 39% increase in by-product gold sales, partially offset by a 24% decrease in silver ounces produced.

All-In-Sustaining Costs ("AISC") decreased by 14% to $25.51 per silver ounce compared to Q3 2023 due to the lower cash costs as noted above, and reduced sustaining capital expenditures, partially offset by higher general and administrative costs.

For the nine months ended September 30, 2024, consolidated direct operating cost per tonne is above the previously noted annual guidance (since retracted) due to lower throughput to date in 2024 following the Guanaceví trunnion failure, partially offset by the cost saving measures actioned in the third quarter. Per ounce guidance metrics are impacted by metal price estimates, royalties, special mining duties and normal variations in ore grades. The higher gold price realized has offset increased input costs in calculating per ounce guidance metrics.

Due to the reduced operating capacity at Guanacevi, operating costs and all in sustaining cost metrics were higher in the quarter than originally guided for 2024. Due to the significant number of variables, estimates and remaining uncertainties, management withdrew its 2024 cost guidance in August.

The Company reported a net loss of $17.3 million for the three-month period ended September 30, 2024, compared to a net loss of $2.3 million in Q3 2023. Excluding certain non-cash and unusual items, and items that are subject to volatility which are unrelated to the Company's operation, adjusted income was $1.6 million compared to an adjusted loss of $8.3 million in Q3 2023.

For the three months ended September 30, 2024, the Company reported revenue of $53.4 million, net of $0.5 million of smelting and refining costs, increased by 8% compared to $49.5 million, net of $0.5 million of smelting and refining costs, in Q3 2023. Gross sales of $53.9 million in Q3 2024 represented an 8% increase over the gross sales of $49.9 million for the same period in 2023. A 26% decrease in silver oz sold during the period, offset by a 24% increase in the realized silver price resulted in an 8% decrease to silver sales. A 7% increase in gold oz sold in combination with a 30% increase in realized gold prices resulted in a 39% increase in gold sales. During the period, the Company sold 1,017,392 oz silver and 9,412 oz gold, for realized prices of $29.63 and $2,528 per oz, respectively, compared to sales of 1,370,032 oz silver and 8,760 oz gold, for realized prices of $23.99 and $1,948 per oz, respectively, in the same period of 2023. For the three months ended September 30, 2024, the realized prices of silver and gold were within 2% of the London spot prices.

The Company decreased its finished goods silver inventory to 117,921 oz and decreased its finished goods gold inventory to 961 oz at September 30, 2024 compared to 268,020 oz silver and 1,261 oz gold at June 30, 2024. The cost allocated to these finished goods was $3.1 million as at September 30, 2024, compared to $6.1 million at June 30, 2024. As of September 30, 2024, the finished goods inventory fair market value was $6.2 million, compared to $10.8 million at June 30, 2024.

Cost of sales for Q3 2024 was $41.0 million, a decrease of 12% over the cost of sales of $46.7 million for Q3 2023. The lower cost of sales compared to the prior period was driven by lower silver ounces sold in the quarter as well as cost management measures undertaken at Guanaceví following the trunnion failure in Q3 2024, including the termination of contract mining activities. At Guanaceví in Q3 2023 higher costs were experienced due to lower mine productivity, an increase in the purchase of third-party ore and additional repair costs associated with the plant shutdown at that time.

Exploration and evaluation expenses were $4.7 million, in line with $4.2 million incurred in the same period of 2023. General and administrative expenses of $4.0 million in Q3 2024 were higher compared to the $2.4 million incurred for the same period of 2023, primarily due to the revaluation of the cash-settled DSU liability caused by an increase in Company's share price, amounting to $0.9 million increase.

The Company incurred a foreign exchange loss of $3.1 million in Q3 2024 compared to a foreign exchange loss of $0.4 million in Q3 2023 due to a weakening of the Mexican peso at the end of the reporting period, which decreased the US dollar value of the Mexican peso denominated working capital surplus. In Q3 2024, the Company incurred $0.5 million in finance charges primarily from interest on loans related to mobile equipment and accretion of reclamation and rehabilitation liabilities, compared to $0.3 million in the same period in 2023. The Company recognized $19.4 million loss for the period on the revaluation of the gold and foreign exchange derivatives (2023 - nil) due to the increase in gold forward prices and appreciation of the US dollar in relation to the Mexican peso.
