We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Independence and ethics

We are independent of the Company in accordance with the International Federation of Accountants' Code of Ethics for Professional Accountants ("the IFAC Code") as adopted by resolutions of the National Council of Statutory

Our audit approach

Overview

Auditors and other ethical requirements that are relevant to our audit of the financial statements in Poland. We have fulfilled our other ethical responsibilities in accordance with these requirements and the IFAC's Code. During the audit, the key registered auditor and the registered audit firm remained independent of the Company in accordance with the independence requirements set out in the Act on Registered Auditors and in the EU Regulation.

As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements. In particular, we considered where the Company's Management Board made subjective judgements; for example, in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain. We also addressed the risk of management override of internal controls, including among other matters, consideration of whether there was evidence

of bias that represented a risk of material misstatement due to fraud.

Materiality

The scope of our audit was influenced by the adopted materiality level. Our audit was designed to obtain reasonable assurance that the financial statements as a whole are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably be expected to influence the

economic decisions of users taken on the basis of the financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall materiality for the financial statements as presented below. These thresholds, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate on the financial statements as a whole.

The concept of materiality is used by the registered auditor both in planning and conducting an audit, as well as in assessing the effect of the misstatements identified during the audit and the unadjusted misstatements (if any), on the financial statements, and also when forming the registered auditor's report. Therefore, all opinions, assertions and statements contained in the registered auditor's report have been made taking into consideration the quantitative and qualitative materiality levels determined in accordance with the audit standards and the registered auditor's professional judgement.

Overall materiality	PLN 175.6 million
How we determined it	4.5% of the arithmetic average of pre-tax profit from the last three financial years, adjusted for the amount of tax on the extraction of certain minerals.
Rationale for the materiality benchmark applied	We have adopted pre-tax profit as the basis for determining materiality, because in our opinion this measure is commonly used to assess the Company's operations by users of financial statements and is a generally accepted benchmark. We adopted the arithmetic average of the last three years due to the volatility of the financial result. We have adjusted the impact of the extraction tax on certain minerals due to the fact that this fee is not dependent on the results achieved by the Company. We assumed significance at the level of 4.5% because based on our professional judgment it is within the acceptable quantitative thresholds of materiality.

We agreed with the Parent Company's Audit Committee that we would inform about the misstatements of the financial statements identified during the audit for a value greater than PLN 17.6 million, as well as those below that amount, if in our opinion this would be justified due to qualitative factors.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period. They include the most significant identified risks of material misstatements, including the identified risks of material misstatement resulting from fraud. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon. We summarized our response to these risks and, when deemed appropriate, presented the most important observations relating to these risks. We do not provide a separate opinion on these matters.

Recognition of revenues from contracts with clients

In 2019, the Company recognized revenues from contracts with customers in the amount of PLN 17 683 million, which were described in part 2 of the financial statements.

The Company generates revenues mainly from the sale of copper, silver and gold. Revenues are recognized when the Company meets the obligation to perform the service in the form of transferred good or services with simultaneous acquisition of control over this asset by the buyer. Revenue is recognized at an amount equal to the transaction price representing the consideration for the goods and services provided, including the pricing formulas used.

Bearing in mind the importance of position in the financial statements of the Company, as well as the susceptibility of the position to the risk of misstatement, we recognized that this is a key matter for our audit.

Key audit matter How our audit addressed the key audit matter

Our testing procedures included in particular:

• understanding the internal control system and analyzing the principles adopted in the Company in terms of recognizing revenue from contracts with clients and identifying the moment of passing control over the good or service provided,
• analysis of the conditions contained in significant sales contracts,
• conducting, on a selected sample, efficiency tests of selected internal controls, important for determining the correct moment of revenue recognition and the correct value of revenues from contracts with clients,
• analysis of trends in recognized revenues from contracts with clients and explanation of unusual events and one-off transactions,
• conducting retail tests on a selected sample, the selection of which used quantitative and qualitative criteria, including agreeing on the price rates used and quantities on issued sales invoices for contracts with customers, delivery documents and payments,
• confirmation of selected sales transactions with the Company's contractors,
• verification, on a selected sample, of sales in the correct reporting period, taking into account the Incoterms terms and conditions of contracts concluded with the Company's contractors,
• assessment of the correctness and completeness of disclosures in the financial statements regarding revenues from contracts with customers.

Recoverability assessment of loans granted to the KGHM International LTD. Group and Future 1 Sp. z o. o.

As at December 31, 2019, the Company reported a balance of loans granted to subsidiaries Future 1 Sp. z o. o. and KGHM International LTD. in the amount of PLN 7,201 million, which is 20% of the total assets of the Company. Receivables due to loans granted to Future 1 Sp. z o. o. and KGHM International LTD. depending

Our testing procedures included in particular

• understanding and assessing the correctness of the applied principle of measuring receivables from loans in accordance with the relevant financial reporting standards,
• checking the mathematical correctness and methodological consistency (using internal valuation experts) of the valuation model of the

on the classification made in accordance with IFRS 9 Financial Instruments, they are measured at:

a) amortized cost, including an allowance for expected credit losses, or

b) fair value through profit or loss.

Disclosures regarding the valuation of receivables from loans granted are presented in note 6.2 of the financial statements.

Determining the amount of the write-off due to expected credit losses, as well as measuring the fair value of receivables from granted loans involves the necessity to make a number of significant assumptions and make judgments, in particular regarding the Company's strategy, macroeconomic and market assumptions as well as predictions regarding legal conditions, financial plans and cash flow projections.

Considering the inherent risk of uncertainty associated with significant estimates made by the Management Board, as well as the significance of items in the financial statements, we have determined that this is a key issue for our audit.

Assessment of the recoverability of investments in subsidiaries' shares

The net value of investments in subsidiaries as at December 31, 2019 was PLN 2 946 million, including:

• investments in shares in Future 1 Sp. z o. o. amounted to PLN 1 185 million,

• investment in shares of Energetyka Sp. z o. o. amounted to PLN 299 million.

Investments in subsidiaries are carried at cost less impairment losses. Accounting policies and disclosures regarding investments in subsidiaries are included in note 6.1 to the annual financial statements.

As at December 31, 2019, the Company identified premises for impairment testing in respect of shares in Future 1 Sp. z o. o. and Energetyka Sp. z o. o.

Disclosures regarding impairment tests of investments in subsidiaries are presented in part 3 of the financial statements.

The correct determination of the write-down revaluating shares is an area that requires significant estimates by the Management Board. Determining the recoverable amount for the value of shares in subsidiaries requires the Management Board

• assessment of the work carried out by external experts used by the Management Board of the Parent Company, including their competences and independence,
• critical assessment of the assumptions made by the Management Board of the Company and the estimates made to determine the expected value of loans and the expected credit losses,
• assessment of the sensitivity analysis carried out by the Management Board of the adopted assumptions for the valuation result,
• assessment of the correctness and completeness of disclosures in the financial statements in the scope of valuation of financial assets from granted loans and assessment of their recoverability.

Our testing procedures included in particular:

• verification of compliance of the adopted valuation principle with applicable accounting standards,
• understanding and evaluation of the process of identification by the Management Board of premises for impairment of investments in subsidiaries,
• understanding and assessment of the correctness of applied methods of testing for impairment in accordance with relevant financial reporting standards,
• checking mathematical correctness and methodological coherence (using internal valuation experts) of the valuation model prepared by the Company's Management Board based on discounted cash flows,
• assessment of work done by external experts used by the Company's Management Board, including their competence and independence,
• critical assessment of accepted assumptions and estimates made by the Company's Management Board to determine the recoverable amount, including, inter alia:
  • o the projection period of future cash flows based on approved budgets of companies for which an impairment test was carried

to estimate, among others, expected future cash flows from investments. Considering the inherent risk of uncertainty associated with significant estimates made by the Management Board, as well as the significance of items in the financial statements, we have determined that this is a key issue for our audit. out and the level of revenues, operating margin and future investment outlays assumed therein, o the applied discount rate (based on weighted average cost of capital), and the residual growth rate after forecast period, • assessment of the sensitivity analysis carried out by the Management Board of the adopted assumptions for the valuation result, • assessment of the correctness and completeness

Presentation of reverse factoring transactions

As at 31 December 2019, the Company presents in the statement of financial position liabilities under reverse factoring in the item Liabilities to suppliers and similar. The value of trade liabilities transferred to reverse factoring as at the balance sheet date was PLN 596 million. Trade liabilities transferred to reverse factoring and not repaid at the end of the reporting period are presented in the statement of financial position as "Liabilities to suppliers and similar"

(where these liabilities fall into the "similar" category) due to the judgment of the Management Board of the Parent Company presented in Note 10.3 to the financial statements.

In the cash flow statement, the Company presents flows resulting from the payment of receivables by the factor as part of the change in working capital. At the same time, the Company separates a separate item as part of the change in working capital representing the change in the amount of liabilities submitted for factoring. The judgment of the Parent Company's Management Board regarding the presentation of cash flows regarding reverse factoring transactions in the part not related to interest in operating activities is presented in Note 10.3 to the financial statements.

Pursuant to IAS 7.11, an entity should present cash flows from operating, investing and financing activities in a manner most appropriate to the type of business conducted, due to the fact that this information provides users of financial statements with data that allows assessing the impact of these activities on the entity's financial position; and on the amount of cash and equivalents.

Due to the heterogeneous market practice in the presentation of reverse factoring in the statement of financial position and statement of cash flows,

Our testing procedures included in particular:

subsidiaries.

of disclosures regarding investments in

• understanding the principles of presentation of reverse factoring transactions applied by the Management Board of the Company and understanding the basis of the judgment made in the context of applicable financial reporting standards and market practice, understanding and assessing the legal impact of the statutory subrogation in accordance with the Civil Code on the classification of reverse factoring transactions in the financial statements,
• analysis and understanding of contractual arrangements with the broker as well as with suppliers under concluded agreements,
• assessment of the correctness and completeness of disclosures regarding reverse factoring in the financial statements, including judgments made by the Management Board of the Company.

We discussed with the Company's Management Board the ambiguity of recording the standards and the lack of detailed regulations regarding the classification and presentation of reverse factoring transactions in the statement of financial position and the statement of cash flows. We have indicated that these issues are currently the subject of lively public debate, and are of interest to supervisory authorities and regulators, which in the future may result in clarifying the regulations in this respect and thus may introduce different presentation and classification rules adopted by the Company.

and the judgment made by the Management Board in this regard, we have determined that this is a key issue for our audit.

Implementation of IFRS 16 Leasing

On January 1, 2019, IFRS 16 Leasing entered into force. It replaced IAS 17 and IFRIC interpretations 4, SIC 15, 27. The Company has been adopting IFRS 16 from January 1, 2019. The description of the impact of implementing IFRS 16 on the Company's financial statements is described in note 1.4.

In the statement of financial position as at December 31, 2019, the carrying amount of the right to use the assets is PLN 507 million, and the value of leasing liabilities is PLN 509 million.

If the contract meets the criteria for recognition as a lease, the Company recognizes the right to use the asset together with an appropriate lease liability determined in the amount of discounted future payments during the lease period.

The implementation of IFRS 16 required certain estimates and calculations, including the identification of leasing and non-leasing components in concluded contracts that had an impact on the measurement of leasing liabilities and assets under the right of use.

Given the significance of the position in the Company's financial statements, as well as the susceptibility of the position to the risk of distortion, we have determined that this is a key issue for our audit.

Our testing procedures included in particular:

• obtaining from the Company's Management Board an assessment of the impact of the new standard and the accounting principles adopted by the Company in this respect,
• understanding the internal control system and analysis of the principles adopted in the Company in the scope of identification and ensuring the completeness of contracts covered by IFRS 16,
• analysis of significant contracts based on which the Company uses assets,
• testing the effectiveness of selected internal controls, relevant to determining the completeness of contracts, based on the selected sample,
• conducting retail tests on the selected sample, the selection of which used quantitative and qualitative criteria, including on reconciliation of the data adopted to determine the asset under the right to use and the lease liability to the contract with the supplier,
• verification and assessment, on a selected sample, of adopted estimates and calculations affecting the value of lease liabilities and assets under the right to of use,
• assessment of the correctness and completeness of disclosures in the field of leasing (including the impact of the application of IFRS 16 for the first time presented in Note 1.3) in the financial statements.

Responsibility of the Management and Supervisory Board for the financial statements

The Management Board of the Company is responsible for the preparation, based on the annual financial statements that give a true and fair view of the Company's financial position and results of operations, in accordance with the International Financial Reporting Standards as adopted by the European Union, the adopted accounting policies, the applicable laws and the Parent Company's Articles of Association, and for such internal control as the Management Board determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Company's Management Board is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Management Board either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

The Company's Management Board and members of its Supervisory Board are obliged to ensure that the financial statements comply with the requirements specified in the Accounting Act. Members of the Supervisory Board

are responsible for overseeing the financial reporting process.

Auditor's responsibility for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the NSA will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence economic decisions of users taken on the basis of these financial statements.

The scope of the audit does not cover an assurance on the Company's future profitability or the efficiency and effectiveness of the Parent Company's Management Board conducting its affairs, now or in future.

As part of an audit in accordance with the NSA, we exercise professional judgement and maintain professional skepticism throughout the audit. We also:

• identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control;
• obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control;
• evaluate the appropriateness of accounting regulations and policies used, and the reasonableness of accounting estimates

and related disclosures made by the Company's Management Board;

• conclude on the appropriateness of the Company's Management Board's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Company to cease to continue as a going concern;
• evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

We communicate with the Company's Audit Committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide the Audit Committee with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated to the Company's Audit Committee, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter

or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be

expected to outweigh the public interest benefits of such communication.
