Recurring fair value measurements are those that are required in the balance sheet at the end of each reporting period. 
 
Non-recurring fair value measurements are those that are required in particular circumstances e.g. when the recoverable
amount of an asset is determined to be fair value less cost to sell according to IAS 36 Impairment of assets. There were no
non-recurring fair value measurements in the six months ending 30 June 2016. 
 
Derivatives in designated hedge accounting relationships are valued using a discounted cash flow analysis valuation model,
which includes observable credit spreads and using the applicable yield curve for the duration of the instruments for
non-optional derivatives, and option pricing models for optional derivatives. These are level 2 inputs as described below. 
 
Available-for-sale investments are investments in shares on active markets and are valued using unadjusted quoted market
values of the shares at the financial reporting date. These are level 1 inputs as described below. 
 
Provisionally priced metal sales for the period are marked-to-market at the end of the period. Gains and losses from the
marking-to-market of open sales are recognised through adjustments to revenue in the income statement and trade debtors in
the balance sheet. Forward prices at the end of the period are used for copper sales while period-end average prices are
used for molybdenum concentrate sales. These are level 2 inputs as described below. 
 
Financial assets measured at fair value through profit and loss are highly liquid current asset investments that are valued
using market prices at the period end. These are level 1 inputs as described below. 
 
The inputs to the valuation techniques described above are categorised into three levels, giving the highest priority to
unadjusted quoted prices in active markets (level 1) and the lowest priority to unobservable inputs (level 3 inputs): 
 
-     Level 1 fair value measurement inputs are unadjusted quoted prices in active markets for identical assets or
liabilities. 
 
-     Level 2 fair value measurement inputs are derived from inputs other than quoted market prices included in level 1
that are observable for the asset or liability, either directly or indirectly. 
 
-     Level 3 fair value measurement inputs are unobservable inputs for the asset or liability. 
 
The degree to which inputs into the valuation techniques used to measure the financial assets and liabilities are
observable and the significance of these inputs in the valuation are considered in determining whether any transfers
between levels have occurred. In the six months ending 30 June 2016 and 30 June 2015, there were no transfers between
levels in the hierarchy. 
 
b)             Embedded derivatives 
 
As explained in Note 5, copper and molybdenum concentrate sale agreements and copper cathode sale agreements generally
provide for provisional pricing of sales at the time of shipment, with final pricing being based on the monthly average
London Metal Exchange copper price or monthly average molybdenum price for specified future periods. The provisional
pricing mechanism within the sale agreements is an embedded derivative under IFRS. Details of the provisional pricing
arrangements are included in Note 5. 
 
c)             Derivative financial instruments 
 
The Group periodically uses derivative financial instruments to reduce its exposure to commodity price, foreign exchange
and interest rate movements.  The Group does not use such derivative instruments for speculative trading purposes. 
 
The Group has applied the hedge accounting provisions of IAS 39 "Financial Instruments: Recognition and Measurement". 
Changes in the fair value of derivative financial instruments that are designated and effective as hedges of future cash
flows have been recognised directly in other comprehensive income, with such amounts subsequently recognised in the income
statement in the period when the hedged item has been recognised in the income statement within revenue. The time value
element of changes in the fair value of derivative options is excluded from the designated hedging relationship, and is
therefore recognised directly in the income statement within other finance items. 
 
(i)            Mark-to-market adjustments and income statement impact 
 
The balance sheet mark-to-market adjustments in respect of derivatives at the end of each period, and the total effect on
the income statement and reserves for each period are as follows. The impact on reserves is shown before tax and
non-controlling interests.

Chile. 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. 
 
On 29 September 2014 a significant reform of the Chilean system was enacted into law. This introduced two alternative
future taxation systems - the partially-integrated system (the default system for the Group's Chilean subsidiaries) or the
attributable system. The Group has been accounting for deferred tax on the basis that it would apply the default
partially-integrated system. On 1 February 2016 a Simplification of the Tax Reform was enacted into law. This specifies
that for entities such as the Group's Chilean subsidiaries, whose members are corporate entities and not individual
persons, only the partially-integrated system can be applied. Given that the Group has already been accounting for deferred
tax on the basis that it would apply the default partially-integrated system this has not resulted in any accounting impact
for the Group. 
 
Under the partially-integrated system the corporate tax rate will be 25.5% in 2017 and 27% from 2018 onwards. The immediate
shareholders of the Chilean subsidiaries will pay withholding tax based on the cash distributions made by those subsidiary
companies, as with the current tax system. If the subsidiary company's shareholders are tax resident in countries with
applicable tax treaties with Chile (as is the case for the Group) the withholding tax will be 35%, less first category tax
at the rate it was paid, so if the company distributes all of its earnings the total corporate and withholding tax burden
will be 35%. 
 
The Group's mining operations are also subject to a mining tax (royalty). Production from Los Pelambres, El Tesoro Central
and Mirador pits at Centinela cathodes, Antucoya and Michilla are currently subject to a rate of 4% of taxable operating
profit and Centinela concentrates of 5%, and production from El 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.

The tax charge for 2016 was $118.0 million and the effective tax rate was 42.7 %. In 2016 the effective tax rate varied
from the statutory rate principally due to tax losses which under Chilean tax carry-back rules generated a credit at
historic tax rates below the current year statutory rate (impact of $11.8 million / 4.3%), the effect of expenses not
deductible for Chilean corporate tax purposes (principally the funding of expenses outside of Chile) (impact of $8.7
million / 3.1 %)  and the mining tax (impact of $32.8 million / 11.8 %) and withholding tax charge (impact of $8.3 million
/ 3.0%). 
 
There are no significant tax uncertainties which would require critical judgements, estimates or potential provisions. 
 
8.   Discontinued operations 
 
(i)     On 24 April 2015 the Group entered into a sale agreement to dispose of Aguas de Antofagasta S.A. ("ADASA"), which
carried out of the group´s water operations. The disposal was completed on 2 June 2015. On 28 August 2015, the Group
disposed of its 100% interest in Empresa Ferroviaria Andina S.A. ("FCA").The results of ADASA and FCA for the period prior
to disposal as well as the profit on disposal have been presented on the "Profit for the period from discontinued

9.   Earnings per share 
 
Basic and diluted earnings per share is calculated on profit after tax and non-controlling interests giving net earnings of
$88.1 million (six months ended 30 June 2015 - $705.8 million, year ended 31 December 2015 - $608.2 million) and amounted
to 8.9 cents and based on 985,856,695 ordinary shares.  There was no potential dilution of ordinary shares in any period. 
 
10. Dividends 
 
The Board has declared an interim dividend of 3.1 cents per ordinary share for the 2016 half year (2015 half year - 3.1
cents).  Dividends are declared and paid gross. Dividends actually paid in the period and recognised as a deduction from
net equity under IFRS were nil per ordinary share (2015 half year - 9.8 cents), representing the final dividend declared in
respect of the previous year. 
 
The interim dividend will be paid on 30 September 2016 to ordinary shareholders that are on the register at the close of
business on 9 September 2016.  Shareholders can elect (on or before 12 September 2016) 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 15 September
2016).  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.

In January 2015 the Group completed its acquisition of 100% of Duluth Metals Limited ("Duluth"). The principal asset of
Duluth was its 60% stake in Twin Metals Minnesota Limited ("Twin Metals"), a company in which the Group held the remaining
40% stake as at December 2014. This transaction has resulted in the Group consolidating 100% of the assets and liabilities
relating to Twin Metals with effect from January 2015, including the above $150.1 million intangible asset reflecting the
value of Twin Metals' mining property assets. The mining properties acquired will be amortised once production commences. 
 
The prior year opening balance of $118.6 related to Aguas de Antofagasta S.A.'s ("ADASA") 30 year concession to operate the
water rights and facilities in the Antofagasta Region of Chile. This balance was disposed of as part of the sale of ADASA
on 2 June 2015, as disclosed in Note 8.

At 30 June 2016 $46.8 million (30 June 2015 - $40.4 million; 31 December 2015 - $44.9 million) of depreciation in respect
of assets relating to Los Pelambres, Centinela, Antucoya and Michilla has been capitalised within property, plant and
equipment or inventories, and accordingly is excluded from the depreciation charge recorded in the income statement as
shown in Note 3(a). 
 
At 30 June 2016 the Group had entered into contractual commitments for the acquisition of property, plant and equipment
amounting to $975.1 million (30 June 2015 - $401.7 million; 31 December 2015 - $283.1 million). 
 
There have been no indicators of potential impairments during the first six months of 2016, and accordingly no impairment
reviews have been performed as at 30 June 2016. The Group performed impairment reviews in respect of the Centinela and
Antucoya operations at the 2015 year-end. For both Centinela and Antucoya the recoverable amount indicated by the review
was greater than the carrying value of the assets, and accordingly no impairment charge was recognised. The following
sensitivities in respect of the valuation estimates of Centinela and Antucoya are still considered relevant to the assets
as at 30 June 2016. The assumptions used in the impairment review calculations which were considered to be subject to the
most estimation uncertainty were the long-term copper price and the discount rate. To illustrate the sensitivity of the
valuations of Centinela and Antucoya to negative movements in these parameters, a 5% decrease in the forecast long-term
copper price would have resulted in an impairment of $375 million at Centinela and an impairment of $95 million at
Antucoya, and an increase in the discount rate from 8% to 9% would have resulted in an impairment of $190 million at
Centinela and an impairment of $50 million at Antucoya. These are simple sensitivities, looking at illustrative movements
in the long-term copper price and discount rate in insolation. In reality, a deterioration in the long-term copper price
environment is likely to result in corresponding improvements in a range of input cost factors, as well as potential
operational changes, which could partly mitigate the above estimated potential impairment charges.

Available-for-sale investments represent those investments which are not subsidiaries, associates or joint ventures and are
not held for trading purposes. The fair value of all equity investments are based on quoted market prices. 
 
The reclassification of $9.4 million is related with the acquisition of Duluth Metals Limited ("Duluth"). As at 31 December
2014 the Group held 17.2% of Duluth's share capital, with a fair value of $9.4 million, accounted for as an available for
sale investment. As explained in Note 14, in January 2015 the Group completed its acquisition of 100% of Duluth. Duluth
holds a 60% stake in Twin Metals Minnesota Limited ("Twin Metals"), a company in which the Group held a 40% stake as at
December 2014. Accordingly, as a consequence of the acquisition of Duluth the Group has a 100% interest in Duluth and as a
result of this a 100% interest in Twin Metals. From January 2015 Twin Metals has therefore been consolidated as a 100%
subsidiary of the Group, with this $9.4 million balance forming part of the total consideration reflected in the accounting
for the acquisition of the subsidiary. 
 
14. Acquisition of 50% stake in Zaldívar 
 
On 1 December 2015 Antofagasta completed its acquisition of a 50% stake in Compañia Minera Zaldívar SpA ("Zaldivar") from
Barrick Gold Corporation ("Barrick"), pursuant to an agreement entered into on 30 July 2015. As a result, Antofagasta has
become operator of the Zaldivar mine. Zaldivar is an open-pit, heap-leach copper mine located in Northern Chile, which
produces approximately 100,000 tonnes of copper cathodes annually. 
 
Given that Antofagasta and Barrick have joint control over Zaldivar, Antofagasta is accounting for its 50% stake in
Zaldivar as a joint venture, using the equity method of accounting. 
 
Total preliminary consideration for the transaction was $1,005.0 million in cash, subject to adjustments based on the net
debt and working capital levels of Zaldivar at the completion date. The net debt and working capital adjustments were
finalised in August 2016 and resulted in a final adjusted consideration of $949.7 million. Including capitalised
acquisition costs of $7.0 million the initial investment in joint venture balance is therefore $956.7 million. The
allocation of the fair values of the individual assets and liabilities effectively contained within the overall investment
in joint venture balance will be completed within 12 months of the acquisition date.

At 30 June 2016 $100.7 million (30 June 2015 - $48.0 million; 31 December 2015 - $30.5 million) of the borrowings has fixed
rate interest and $3,119.1 million (30 June 2015 - $2,428.4 million; 31 December 2015 - $2,724.6 million) has floating rate
interest. The Group periodically enters into interest rate derivative contracts to manage its exposure to interest rates.
As explained in Note 5, these include interest rate swaps which have the effect of converting $225.0 million of floating
rate borrowings into fixed rate borrowings. Details of any derivative instruments held by the Group are given in Note
5(c). 
 
During the period de Group entered into a loan agreement of $500.0 million. This borrowing has variable interest rate of
LIBOR six-months plus 1.5% spread with a duration of five years.
