Disclosures notified in accordance with DTR 3.1.2R

Antofagasta plc (the "Company") announces that, on 25 March 2015, awards calculated by reference to the value of ordinary shares in the Company ("Shares") were granted under the Antofagasta Long Term Incentive Plan (the "LTIP") to Persons Discharging Managerial Responsibility ("PDMR") of the Company as set out below:

These are awards granted under the LTIP which the Antofagasta group (the "Group") has established to reward senior executives in a way that aligns their interests with the interests of shareholders and with the Group's long-term strategic plan.  Directors of the Company are not eligible to participate in the LTIP.

Awards granted under the LTIP are conditional rights to receive a cash payment by reference to the number of Shares relating to the relevant award which vest under the LTIP.  The cash payment is determined by reference to the market value of the Shares at vesting.  No Shares are issued to participants in the LTIP.  No consideration was paid for the grant of any awards.

Performance awards are subject both to certain performance conditions, which are measured over a three year period (2015-2017), and to continued employment.  Performance awards will normally vest only after the end of the three year performance period and only to the extent that those performance conditions are met.

Restricted awards are subject to continued employment and normally one third will vest in March 2016, one third in March 2017 and the final third in March 2018.
