The rate of first category (i.e. corporation) tax in Chile is currently 20%.
The Group's mining operations are also subject to a mining tax (royalty). Production from Los Pelambres, the Tesoro Central
and Mirador pits at Centinela cathodes and Michilla are subject to a rate of 4% of taxable operating profit and Centinela
concentrates of 5%, and production from the Tesoro North East pit and the run-of-mine processing at Centinela cathodes is
subject to a rate of between 5-14%, depending on the level of operating profit margin.
In addition to first category tax and the mining tax, the Group incurs withholding taxes on any remittance of profits from
Chile and deferred tax is provided on undistributed earnings to the extent that remittance is probable in the foreseeable
future. Withholding tax is levied on remittances of profits from Chile at 35% less first category (i.e. corporation) tax
already paid in respect of the profits to which the remittances relate.

The tax charge for the six months ended 30 June 2014 was US$279.1 million and the effective tax rate was 32.8 %. This rate
varied from the standard rate (comprising first category tax) principally due to the effect of items not deductible from
first category tax (mainly corporate items which principally comprise exploration and evaluation costs), a withholding tax
charge of US$48.8 million and the effect of the mining tax which resulted in a charge of US$43.4 million.
In April a comprehensive tax reform bill was presented to the Chilean National Congress. The key proposed tax changes set
out in the bill which will impact the Group relate to corporate tax and withholding tax. The bill has been passed by the
Chamber of Deputies, but following a period of deliberation by the Senate a number of changes to the original bill have
been proposed, including an alternative corporate and withholding tax structure. The amended bill was returned to the
Chamber of Deputies where further amendments have been introduced and the bill is expected to re-presented to the Senate
for approval in August or September. As certain parts of the bill are intended to be retrospective to the beginning of
this year the Government is keen that the bill is passed as soon as possible to allow adequate time for their
implementation. It is therefore expected that the bill will be passed by the end of September.
8. Earnings per share
Basic and diluted earnings per share is calculated on profit after tax and non-controlling interests giving net earnings of
US$330.8 million (six months ended 30 June 2013 - US$395.0 million, year ended 31 December 2013 - US$659.6 million) and
amounted to 33.6 cents and based on 985,856,695 ordinary shares. There was no potential dilution of ordinary shares in any
period.
9. Dividends
The Board has declared an interim dividend of 11.7 cents per ordinary share for the 2014 half year (2013 half year - 8.9
cents). Dividends are declared and paid gross. Dividends actually paid in the period and recognised as a deduction from
net equity under IFRS were 86.1 cents per ordinary share (2013 half year - 90.0 cents), representing the final dividend
declared in respect of the previous year.
The interim dividend will be paid on 9 October 2014 to ordinary shareholders that are on the register at the close of
business on 19 September 2014. Shareholders can elect (on or before 22 September 2014) to receive this interim dividend in
US Dollars, Pounds Sterling or Euro, and the exchange rate to be applied to interim dividends to be paid in Pounds Sterling
or Euro will be set as soon as reasonably practicable after that date (which is currently anticipated to be on 25 September
2014). Further details of the currency election timing and process (including the default currency of payment) are
available on the Antofagasta plc website (www.antofagasta.co.uk) or from the Company's registrar, Computershare Investor
Services PLC on +44 870 702 0159.

17. Contingent liabilities
Antofagasta plc or its subsidiaries is subject to various claims which arise in the ordinary course of business. No
provision has been made in the financial statements and none of these claims are currently expected to result in any
material loss to the Group. Details of the principal claims in existence either during, or at the end of, the period and
the current status of these claims are set out below:
Los Pelambres - Mauro tailings dam
As previously announced, during 2008 Los Pelambres entered into binding settlements in respect of litigation relating to
the Mauro tailings dam. Since that time, Los Pelambres has become aware of further legal proceedings which had been
initiated in first instance courts in Santiago and Los Vilos by representatives of certain members of the Caimanes
community located near the Mauro valley. These claims, some of which have already been rejected by the relevant courts,
sought to stop the operation of the Mauro tailings dam. Two of these claims are currently ongoing and Los Pelambres is
continuing to take necessary steps to protect its position.
In the first of these claims, the plaintiffs have argued that the tailings dam affects their alleged water rights and the
environment. This claim was rejected by the Court of first instance of Los Vilos in a judgment issued in November 2012,
which was than affirmed by the Court of Appeals of La Serena in August 2013. An action to vacate this last judgment, based
only on the application of the law (cassation), was later filed by the plaintiffs before the Supreme Court and is currently
pending.
In the second claim, the plaintiffs are seeking demolition of the dam on the basis of the risk that its collapse would pose
to the community. The Court of Los Vilos issued a decision in May 2014 denying the demolition request but ordering Minera
Los Pelambres to undertake some additional measures to ensure protection of the community, in case a major earthquake or
natural event occurs. These measures need to be reviewed and agreed with the technically competent bodies responsible for
supervision of the dam. The decision of the Court of Los Vilos, has been appealed by both claimant and the defendant and
these appeals will be heard before the Court of Appeal of La Serena. Any decision of the Court of Appeal may also be
subject to a review of the correct application of law by the Supreme Court of Chile.
18. Post balance sheet events
On 3 July 2014 Antofagasta terminated its option to acquire an additional 25% of Twin Metals Minnesota LLC ("TMM"). As a
result of being provided the option termination notice, Duluth Metals Limited ("Duluth Metals") has a right to purchase,
within 180 days, Antofagasta's 40% of TMM for a price equal to Antofagasta's sunk costs (currently estimated to be
approximately US$220m) plus approximately US$10m currently outstanding (plus accrued and unpaid interest) under a bridge
loan facility. If Duluth Metals does not exercise its buy-back right, Antofagasta will continue to own 40% of TMM and
Duluth Metals will be required to repay the loan facility, at its option, in either cash or Duluth Metals shares. Following
the termination of the option, Duluth Metals controls the management and development of the Twin Metals Project.
19. Litigation

preliminary issues was heard by the ICC tribunal in the week commencing 23 June 2014 and a decision is expected in the
coming months. The ICSID tribunal has scheduled a hearing on jurisdiction and liability to take place over a two-week
period commencing 6 October 2014.

INDEPENDENT REVIEW REPORT TO ANTOFAGASTA PLC
We have been engaged by the company to review the condensed set of financial statements in the half-yearly financial report
for the six months ended 30 June 2014 which comprises the condensed consolidated income statement, the condensed
consolidated balance sheet, the condensed consolidated statement of changes in equity the condensed consolidated cash flow
statement and related notes 1 to 20. We have read the other information contained in the half-yearly financial report and
considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed
set of financial statements.
This report is made solely to the company in accordance with International Standard on Review Engagements (UK and Ireland)
2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing
Practices Board. Our work has been undertaken so that we might state to the company those matters we are required to state
to it in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or
assume responsibility to anyone other than the company, for our review work, for this report, or for the conclusions we
have formed.
Directors' responsibilities
The half-yearly financial report is the responsibility of, and has been approved by, the directors. The directors are
responsible for preparing the half-yearly financial report in accordance with the Disclosure and Transparency Rules of the
United Kingdom's Financial Conduct Authority.
As disclosed in note 1, the annual financial statements of the group are prepared in accordance with IFRSs as adopted by
the European Union. The condensed set of financial statements included in this half-yearly financial report has been
prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting," as adopted by the European
Union.
Our responsibility
Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the
half-yearly financial report based on our review.
Scope of review
We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410 "Review of
Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board
for use in the United Kingdom. A review of interim financial information consists of making inquiries, primarily of persons
responsible for financial and accounting matters, and applying analytical and other review procedures. A review is
substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK and Ireland)
and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be
identified in an audit. Accordingly, we do not express an audit opinion.
Conclusion
Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial
statements in the half-yearly financial report for the six months ended 30 June 2014 is not prepared, in all material
respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and
Transparency Rules of the United Kingdom's Financial Conduct Authority.
