For the year ended December 31, 2021, net revenue, net of $2.0 million of smelting and refining costs, increased by 19% to $165.3 million (2020: $138.4 million).

Gross sales of $167.3 million in 2021 represented a 19% increase over the $140.2 million in 2020. Silver oz sold increased by 11% with a 17% increase in the realized silver price, resulting in a 30% increase in silver sales. Gold oz sold increased by 10% with a 3% reduction in the realized gold price, resulting in a 7% increase in gold sales. During the period, the Company sold 3,856,883 oz silver and 39,113 oz gold for realized prices of $25.22 and $1,790 per oz, respectively, compared to sales of 3,460,638 oz silver and 35,519 oz gold for realized prices of $21.60 and $1,846 per oz, respectively, in 2020. In 2021, silver and gold London spot prices averaged $25.14 and $1,799, respectively.

The Company significantly increased its finished goods silver and gold inventory to 1,082,610 oz and 3,674 oz, respectively, at December 31, 2021 compared to 116,484 oz silver and 1,459 oz gold at December 31, 2020. The cost allocated to these finished goods was $15.6 million at December 31, 2021 compared to $3.6 million at December 31, 2020. At December 31, 2021, the finished goods inventory fair market value was $31.7 million, compared to $5.8 million at December 31, 2020. Earnings and other financial metrics, including mine operating cash flow(2), operating cash flow(2) and EBITDA(2) were impacted by the increased bullion inventory held at year end.

After cost of sales of $128.9 million (2020 - $111.1 million), an increase of 16%, mine operating earnings were $36.4 million (2020 - $27.3 million). The increase in cost of sales was due to increased production, labour, power and consumables costs and significantly higher royalty costs, offset by improved productivity at the Guanacevi and Bolanitos operations. Royalties increased 69% to $13.8 million due to increased mining of the high-grade Porvenir and Porvenir Cuatro extensions at the Guanacevi operation, which are subject to significantly higher royalty rates. During 2021 the Company's operations experienced higher than budgeted costs due to global supply constraints, inflationary pressure, materials shortages, labour costs tracking higher than planned and increased purchased ore at the Guanacevi operation. In 2020, there was a temporary suspension of the Guanacevi, Bolanitos and El Compas operations due to COVID-19, which impacted sales and costs of sales during that period.

The Company had operating earnings of $22.3 million (2020: operating loss $0.8 million) after exploration and evaluation costs of $17.9 million (2020: $9.8 million), general and administrative costs of $10.1 million (2020: $12.7 million), an impairment reversal of $16.8 million (2020: $0.4 million impairment expense), care and maintenance cost of $1.3 million (2020: $5.2 million), severance cost of $0.7 million in severance (2020: $Nil) and a write-off of exploration properties of $0.7 million (2020: $Nil). The impairment reversal of $16.8 million is resulting from the valuation assessment performed for the El Cubo mine and related assets upon classification as held for sale whereas the 2020 impairment charge on non-current assets of $0.4 million related to the value in use estimates of the Guanacevi and El Compas operations. The $1.3 million in care and maintenance costs for 2021 are comprised of $0.7 million recognized for the El Cubo operation for costs to the sale of the mine and related assets in April 2021, and $0.6 million recognized for the El Compas operation, where operations were suspended in mid-August, 2021. During the comparative period of 2020 the Company recognized $3.0 million in care and maintenance costs for the suspended El Cubo operation and $2.2 million in care and maintenance costs related to the temporary suspension of the Guanacevi, Bolanitos and El Compas operations due to COVID-19.

Earnings before income taxes were $29.7 million (2020: loss before income taxes $1.0 million) after finance costs of $1.0 million (2020: $1.3 million), a foreign exchange loss of $1.1 million (2020: $1.5 million), a gain on disposal of the El Cubo mine and related assets of $5.8 million (2020: $Nil) and investment and interest income of $3.7 million (2020: $2.6 million).

The Company realized net earnings for the period of $14.0 million (2020: $1.2 million) after an income tax expense of $15.7 million (2020: income tax recovery of $2.2 million). Current income tax expense increased to $3.5 million (2020 - $3.0 million) due to increased profitability impacting the special mining duty, while deferred income tax expense of $12.2 million is primarily due to the estimated use of loss carryforwards to reduce taxable income at Guanacevi (2020 - deferred income tax recovery $5.2 million).

Direct operating costs(2) on a per tonne basis increased to $115.36, up 14% compared with 2020 due to higher operating costs at Guanacevi and Bolanitos. Guanacevi and Bolanitos have seen increased labour, power and consumables costs and at Guanacevi, increased third party ore purchased and operating development have increased compared to the prior year. There has also been a slight appreciation of the Mexican Peso to US Dollar foreign exchange rate compared to the prior period, which increased expenses denominated in Mexican Pesos.

Consolidated cash costs per oz, net of by-product credits, increased to $9.31 primarily due to the higher direct costs per tonne and lower realized gold prices compared to 2020. All-in sustaining costs increased 16% to $20.34 per oz in 2021 as a result of higher cash costs, increased mine site exploration expenses and increased capital expenditures at Guanacevi to accelerate mine development within the El Curso ore body. Actual cost metrics were slightly higher than 2021 cost guidance primarily due to the increased costs relating to labour, power, consumables, increased third party ore purchases, higher royalties and special mining duty offset by the higher ore grades mined at Guanacevi.
