We have audited the accompanying Standalone Financial Statements of Hindustan Copper Limited (“the Company”),

which comprise the Balance Sheet as at March 31, 2024, the Statement of Profit and Loss (including Other Comprehensive Income), the Statement of Changes in Equity and the Statement of Cash Flows for the year ended on that date, and notes to the Standalone Financial Statements including a summary of the significant accounting policies and other explanatory information (hereinafter referred to as “the Standalone Financial Statements”).

In our opinion and to the best of our information and according to the explanations given to us, the aforesaid Standalone Financial Statements give the information required by the Companies Act, 2013 (“ the Act”) in the manner so required and give a true and fair view in conformity with the Indian Accounting Standards prescribed under section 133 of the Act read with the Companies (Indian Accounting Standards) Rules, 2015, as amended, (“Ind AS”) and other accounting principles generally accepted in India, of the state of affairs of the Company as at March 31, 2024 and its profit (including Other Comprehensive Income), changes in equity and its cash flows for the year ended on that date.

Basis for Opinion

We conducted our audit of the Standalone Financial Statements in accordance with the Standards on Auditing (SAs) specified under section 143(10) of the Act. Our responsibilities under those Standards are further described in the “Auditor's Responsibilities for the Audit of the Standalone Financial Statements” section of our report. We are independent of the Company in accordance with the Code of Ethics issued by the

Institute of Chartered Accountants of India (ICAI) together with the ethical requirements that are relevant to our audit of the Standalone Financial Statements under the provisions of the Act and the Rules made thereunder, and we have fulfilled our other ethical responsibilities in accordance with these requirements and the Code of Ethics. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion on the Standalone Financial Statements.

Emphasis of Matters

We draw attention to the following matters:

a) Note No. 40 (1)(i) of the accompanying Standalone Financial Statements which describes the uncertainty related to the outcome of the lawsuits filed and demands raised against the Company by various parties and Government authorities;

b) Note No. 40(3) of the accompanying Standalone Financial Statements which states that the Lease agreement for Rakha Mining Lease at the Indian Copper Complex was valid up to 28.08.21. It is also to be noted that the Lease agreement for Kendadih mines expire on 02.06.23. Application for renewal for both the lease agreements have been submitted as per regulations, and is currently under process;

c) Note 40(3) of the Standalone Financial Statements which states that the mined-out ore kept at pit top of Surda at the Indian Copper Complex mine has not been transported to the Concentrator Plant since July 2022, due to non-issuance of challan/permit by State Authorities, Jharkhand due to non-receipt of Surda Lease Deed, which is under process. Consequently the vendor bills are lying unprocessed and further extraction of ore is currently not happening and not accounted for;

d) Note No. 40(4) of the accompanying Standalone Financial Statements wherein the Company has made assessment of possible impairment loss during the year with respect to Plant and Machinery of Moubhandar Plant, Sulphuric Acid Plant & Nickel Plant at the Indian Copper Complex(ICC)having book value of ^ 4620.20 Lakhs. The study revealed that the fair market value of the specified Plant and Machinery as on 31st March 2024, as reported by the Valuer ^ 3110.76 Lakhs was lower than their Book value and consequently there is requirement to recognize the Impairment Loss ^ 1509.44 Lakhs during the year, as per provisions of Ind AS 36;

e) Note No.40 (5) of the accompanying Standalone Financial Statements which states that the title deeds for freehold and leasehold acquired in respect of Gujarat Copper Project (GCP) with Gross book value of ^ 3795.26 Lakh as at March 31,2024 are yet to be executed in favor of the Company;

f) Note No.40 (7) of the accompanying Standalone Financial Statements wherein, balances under the head Claims Recoverable, Loans & Advances, Deposits from and with various parties and certain balances of trade receivables, trade payables and other current liabilities have not been confirmed as at March 31, 2024, although letters have been sent by the Company seeking confirmation of balances. Consequential impact upon receipt of such confirmation /

reconciliation / adjustments of such balances, if any is not ascertainable at this stage.

Our opinion is not modified in respect of these matters.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the Standalone Financial Statements of the year ended March 31, 2024. These matters were addressed in the context of our audit of the Standalone Financial Statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. We have determined the matters described below to be the key audit matters to be communicated in our report.

Information Other than the Standalone Financial Statements and Auditor's Report Thereon

The Company's Board of Directors is responsible for the other information. The other information comprises the information included in the Report of the Board of Directors, Management Discussion and Analysis Report, Report on CSR activities, Business Responsibility and sustainability Report, Corporate Governance Report and other annexure to Directors Report including Shareholder's Information, but does not include the Standalone Financial Statements and our auditor's report thereon. The Report of the Board of Directors including annexures and other related statements forming part of the Company's annual report is expected to be made available to us after the date of our this auditor report.

Our opinion on the Standalone Financial Statements does not cover the other information and we do not express any form of assurance or conclusion thereon.

In connection with our audit of the Standalone Financial Statements, our responsibility is to read the other information when it becomes available and, in doing so, consider whether the other information is materially inconsistent with the Standalone Financial Statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If based on the work we have performed, we conclude that there is a material misstatement of this other information; we are required to report that fact. We have nothing to report in this regard.

If, based on the Report of the Board of Directors including annexures and other related statements which form part of the annual report and made available to us after the date of this audit report, we conclude that there is a material misstatement therein, we are required to communicate the matter to those charged with governance

Responsibility of Management and Those Charged with Governance for the Standalone Financial Statements

The Company's Board of Directors is responsible for the matters stated in section 134(5) of the Act with respect to the preparation of these Standalone Financial Statements that give a true and fair view of the financial position, financial performance, changes in equity and cash flows of the Company in accordance with the accounting principles generally accepted in India, including the Indian Accounting Standards

specified under Section 133 of the Act. This responsibility also includes maintenance of adequate accounting records in accordance with the provisions of the Act for safeguarding the assets of the Company and for preventing and detecting frauds and other irregularities; selection and application of appropriate accounting policies; making judgments and estimates that are reasonable and prudent; and design, implementation and maintenance of adequate internal financial controls, that were operating effectively for ensuring the accuracy and completeness of the accounting records, relevant to the preparation and presentation of the Standalone Financial Statements that give a true and fair view and are free from material misstatement, whether due to fraud or error.

In preparing the Standalone Financial Statements, the Board of Directors 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 Board of Directors either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

The Board of Directors is also responsible for overseeing the Company's financial reporting process.

Auditor's Responsibilities for the Audit of the Standalone Financial Statements

Our objectives are to obtain reasonable assurance about whether the Standalone 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 SAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these Standalone Financial Statements.

As part of an audit in accordance with SAs, we exercise professional judgment 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 controls relevant to the audit in order to design audit procedures that are appropriate in the circumstances. Under section 143(3) (i) of the Act, we are also responsible for expressing our opinion on whether the Company has adequate internal financial controls system in place and the operating effectiveness of such controls.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

• Conclude on the appropriateness of management'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 Standalone 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 Standalone Financial Statements, including the disclosures, and whether the Standalone Financial Statements represent the underlying transactions and events in a manner that achieves fair presentation.

Materiality is the magnitude of misstatements in the Standalone Financial Statements that, individually or in aggregate, makes it probable that the economic decisions of a reasonably knowledgeable user of the Standalone Financial Statements may be influenced. We consider quantitative materiality and qualitative factors in (i) planning the scope of our audit work and in evaluating the results of our work; and (ii) to evaluate the effect of any identified misstatements in the Standalone Financial Statements.

We communicate with those charged with governance 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 those charged with governance 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 with those charged with governance, we determine those matters that were of most significance in the audit of the Standalone 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.
