Operating And Financial Overview

_{⁽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.com and on EDGAR at www.sec.gov.}

Direct operating costs per tonne in Q2 2024 increased to $140.36, a 7% increase compared to $131.79 in Q2 2023. The increase in the cost per tonne compared to the prior period was driven by a strengthened Mexican peso contributing to higher labour, power and consumables costs. In 2023, the Company faced significant inflationary pressures, which have eased in 2024 but still persist.

Consolidated cash costs per silver ounce, net of by-product credits, in Q2 2024 decreased to $13.43 per silver ounce, a 1% decrease compared with $13.52 per silver ounce in Q2 2023, driven by an increase in by-product gold sales, but largely offset by an increase in direct operating costs per tonne as noted above, and a decrease in silver ore grades.

All-In-Sustaining Costs ("AISC") increased by 4% on a per ounce basis compared to Q2 2023 due to the higher general and administrative costs and higher share-based compensation, partially offset by reduced sustaining capital expenditures.

For the six months ended June 30, 2024, consolidated direct operating costs per tonne is above annual guidance due to higher purchased material at Guanacevi and slightly higher direct input costs than estimated. At Guanacevi purchased material from local miners increased to 18% of throughput and accounted for $5.0 million or $23.02 of consolidated direct operating costs per tonne, In Q2, 2023, purchased material was $1.5 million or $6.38 of consolidated direct operating costs per tonne. With higher precious metal prices, the availability and cost of the purchased material have both increased. 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. Management estimates costs per ounce metrics will be near the lower end of the guidance range, while direct operating costs per tonne will remain above guidance due to the higher metal prices.

Management assumed $23 per oz silver price, $1,840 per oz gold price and 17:1 Mexican peso to U.S. dollar exchange rate in calculating its 2024 cost guidance.

The Company reported a net loss of $14.0 million for the three-month period ended June 30, 2024 compared to a $1.0 million loss in Q2 2023. Excluding certain non-cash and unusual items, and items that are subject to volatility which are unrelated to the Company's operation, adjusted loss was $1.0 million compared to adjusted earnings of $1.6 million in Q2 2023.

For the three months ended June 30, 2024, revenue of $58.3 million, net of $0.4 million of smelting and refining costs, increased by 17% compared to $50.0 million, net of $0.9 million of smelting and refining costs, in Q2, 2023. Gross sales of $58.7 million in Q2 2024 represented a 15% increase over the gross sales of $50.9 million for the same period in 2023. A 6% decrease in silver ounces sold during the period, combined with a 19% increase in the realized silver price resulted in an 11% increase in silver sales. Gold oz sold were in line with comparative period, with a 21% increase in realized gold prices resulting in a 22% increase in gold sales. During the period, the Company sold 1,217,569 oz silver and 9,887 oz gold, for realized prices of $28.94 and $2,374 per oz, respectively, compared to sales of 1,299,672 oz silver and 9,883 oz gold, for realized prices of $24.27 and $1,955 per oz, respectively, in the same period of 2023. Silver and gold London spot prices averaged $28.68 and $2,337, respectively, during the three months ended June 30, 2024.

The Company increased its finished goods metal inventory to 268,020 oz and to 1,261 oz gold at June 30, 2024, compared to 182,128 oz silver and 779 oz gold at March 31, 2024. The cost allocated to these finished goods was $6.1 million at June 30, 2024, compared to $4.0 million at March 31, 2024. As of June 30, 2024, the finished goods inventory fair market value was $10.8 million, compared to $6.2 million at March 31, 2024.

Cost of sales for Q2 2024 was $48.0 million, an increase of 28% over the cost of sales of $37.5 million for Q2 2023. The increase in the cost of sales compared to the prior period was driven by a strengthened Mexican peso contributing to higher labour, power and consumables costs. Throughout 2023, the Company faced significant inflationary pressures, which have eased in 2024 but still persist. Additionally, in Q2 2024 purchased material from local miners increased to 18% of Guanacevi throughput and accounted for $5.0 million of cost of sales, an increase of $3.5 million compared to Q2 2023. The Company incurred increased depreciation costs during Q2 2024 compared to the prior period, due to lower reserve estimates at its' operations.

The Company reported operating earnings of $1.7 million after exploration, evaluation and development costs of $4.3 million and general and administrative costs of $4.3 million. Exploration and evaluation expenses were $4.3 million, in line with $4.3 million incurred in the same period of 2023. General and administrative expenses of $4.2 million were 80% higher compared to the $2.4 million incurred for the same period of 2023; the $1.9 million increase is primarily attributable to the appreciation of the Company's share price and the revaluation of liability recognized for cash settled deferred share units.

Finance costs, a foreign exchange loss, loss on derivative contracts and investment and other income contributed to a loss before income taxes of $11.3 million compared to $4.2 million earnings before taxes in Q2 2023.

The Company incurred a foreign exchange loss of $4.0 million in Q2 2024 compared to a foreign exchange gain of $1.9 million in Q2 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. As part of the Debt Facility agreement, the Company entered into forward gold sale contracts and Mexican Peso purchase contracts. The Company recognized a $9.3 million loss on these derivative contracts due to the increase in gold forward prices and the depreciation of the Mexican peso in relation to the US dollar at June 30, 2024.
