Subsequent to Year End

On February 21, 2024, the Company announced receipt of the environmental permit to develop and mine below the 1120 level at its Yauricocha mine. This permit should provide several significant benefits for Sierra Metals, such as potential operational enhancements, maximization of operating capacity and potential cost efficiencies. With a modest development capital investment, the Company anticipates ramping up to full production levels of 3,600 tonnes per day (“tpd”) by Q4 2024 (see news release).

Outlook for 2024

Management expects 2024 to be the year to consolidate the optimization efforts that started in 2023 and to establish the platform for growth. In 2023, under the guidance of the new management team, the Company began a process of stabilization and optimization.

Prioritizing safety, employee engagement and streamlining operations have helped restore production levels, while strategic debt refinancing has stabilized the Company’s financial position. In February 2024 the Company obtained the environmental permit to develop and mine below the 1120 level at the Yauricocha mine. This permit provides several significant catalysts for Sierra Metals, such as operational enhancements, maximized operating capacity and cost efficiencies. Using a modest development capital investment, the Company anticipates ramping up to full production levels of 3,600 tonnes per day (40% higher than current levels) by Q4 2024.

At Bolivar, the Company will continue the construction of the new tailings dam, which is expected to be completed over the next three years, allowing the mine to increase its production capacity to 7,500 tpd in the future.

Identifying additional mineral resources at the Company’s core operating mines, Yauricocha and Bolivar, is another key priority. The Company anticipates completion of revised mineral resources models during Q2 2024, followed by the corresponding National Instrument 43-101 technical reports.

2024 Capex Guidance

A breakdown by mine of the throughput and planned capital investments is shown in the following table:

	Yauricocha		Bolivar		Consolidated
(Amounts in $M)	Low	High	Low	High	Low	High
Sustaining	12.5	15.6	17.4	21.8	29.9	37.4
Growth	1.9	2.3	7.4	9.3	9.3	11.6
Total	14.4	17.9	24.8	31.1	39.2	49.0

Total capital for 2024 is expected to range between $39.2 million to $49.0 million, with Management retaining the option to adjust the capital expenditure plan depending on the business conditions. Sustaining capital mainly comprises of mine development of up to $14.7 million ($8.9 million in Bolivar and $5.8 million in Yauricocha). The remaining sustaining capital expenditure consists of infill drilling and replacement of equipment at the mines.

Growth capital for 2024 is expected to range between $9.3 million to $11.6 million, focusing on the new tailings dam at Bolivar.

Non-IFRS Measures

Cash costs per copper equivalent pound, All-in-sustaining costs ("AISC") per copper equivalent pound, Adjusted EBITDA and Adjusted net income (loss) attributable to shareholders are non-IFRS performance measures. Management believes these measures better reflect the Company’s performance for the current period and are indicative of its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company’s underlying performance. These measures are intended to provide additional information, but do not have any standardized meaning prescribed by IFRS and are therefore unlikely to be directly comparable to similar measures presented by other issuers.

Non-IFRS Reconciliation of Adjusted EBITDA

EBITDA is a non-IFRS measure that represents an indication of the Company’s continuing capacity to generate earnings from operations before taking into account management’s financing decisions and costs of consuming capital assets, which vary according to their vintage, technological currency, and management’s estimate of their useful life. EBITDA comprises revenue less operating expenses before interest expense (income), property, plant and equipment amortization and depletion, and income taxes. Adjusted EBITDA has been included in this document. Under IFRS, entities must reflect in compensation expense the cost of share-based payments. In the Company’s circumstances, share-based payments involve a significant accrual of amounts that will not be settled in cash but are settled by the issuance of shares in exchange for cash. As such, the Company has made an entity specific adjustment to EBITDA for these expenses. The Company has also made an entity-specific adjustment to the foreign currency exchange (gain)/loss. The Company considers cash flow before movements in working capital to be the IFRS performance measure that is most closely comparable to adjusted EBITDA.

The following table provides a reconciliation of adjusted EBITDA to the consolidated financial statements for the three months and years ended December 31, 2023 and 2022:

	Three months ended December 31,						Year ended December 31,

Adjusted EBITDA from continuing operations		12,233			(675	)		50,289			9,621

Non-IFRS Reconciliation of Adjusted Net Income (Loss)

Adjusted net income (loss) attributable to shareholders represents net income (loss) attributable to shareholders excluding certain impacts, net of taxes, such as non-cash depletion charge due to the acquisition of Corona, impairment charges and reversal of impairment charges, write-down of assets, and certain non-cash and non-recurring items including but not limited to share-based compensation and foreign exchange (gain) loss. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors may want to use this information to evaluate the Company’s performance and ability to generate cash flows. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance in accordance with IFRS.

The following table provides a reconciliation of adjusted net income (loss) to the consolidated financial statements for the three months and years ended December 31, 2023 and 2022:

	Three months ended December 31,						Year ended December 31,

Cash Cost per Copper Equivalent Payable Pound

The Company uses the non-IFRS measure of cash cost per copper equivalent payable pound to manage and evaluate operating performance. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company’s performance and ability to generate cash flows. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The Company considers cost of sales per copper equivalent payable pound to be the most comparable IFRS measure to cash cost per copper equivalent payable pound and has included calculations of this metric in the reconciliations within the applicable tables to follow.

All-in Sustaining Cost per Copper Equivalent Payable Pound

All‐In Sustaining Cost (“AISC”) is a non‐IFRS measure and is calculated based on guidance provided by the World Gold Council (“WGC”). WGC is not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied, as well as differences in definitions of sustaining versus development capital expenditures.

AISC is a more comprehensive measure than cash cost per pound for the Company’s consolidated operating performance by providing greater visibility, comparability and representation of the total costs associated with producing copper from its current operations.

The Company defines sustaining capital expenditures as, “costs incurred to sustain and maintain existing assets at current productive capacity and constant planned levels of productive output without resulting in an increase in the life of assets, future earnings, or improvements in recovery or grade. Sustaining capital includes costs required to improve/enhance assets to minimum standards for reliability, environmental or safety requirements. Sustaining capital expenditures excludes all expenditures at the Company’s new projects and certain expenditures at current operations which are deemed expansionary in nature.”

Consolidated AISC includes total production cash costs incurred at the Company’s mining operations, including treatment and refining charges and selling costs, which forms the basis of the Company’s total cash costs. Additionally, the Company includes sustaining capital expenditures and corporate general and administrative expenses. AISC by mine does not include certain corporate and non‐cash items such as general and administrative expense and share-based payments. The Company believes that this measure represents the total sustainable costs of producing copper from current operations and provides the Company and other stakeholders of the Company with additional information of the Company’s operational performance and ability to generate cash flows. As the measure seeks to reflect the full cost of copper production from current operations, new project capital and expansionary capital at current operations are not included. Certain other cash expenditures, including tax payments, dividends and financing costs are also not included.

The following table provides a reconciliation of cost of sales to cash cost, as reported in the Company’s consolidated statement of income for the three months and years ended December 31, 2023 and 2022:

		Three months ended						Three months ended
