Hochschild Mining PLC
04 October 2007


Notification of transactions of directors, persons discharging managerial
responsibility or connected persons

In accordance with Disclosure Rule 3.1.4R(1), Hochschild Mining plc (the
'Company') announces that it was notified today that Eduardo Hochschild and
Alberto Beeck, executive directors of the Company, have reorganised their
shareholding interests in the Company in a manner that requires disclosure 
under Disclosure Rule 3.1.2R, further details of which are set out below.

In order to effect the reorganisation a waiver of the lock-up entered into 
at the time of the Company's initial public offering ('IPO') was granted by
JPMorgan Cazenove and Goldman Sachs International, the joint global coordinators
of the IPO. No shares in the Company were transferred to a third party as a
result of the reorganisation, with the combined shareholding interest of Mr
Hochschild and Mr Beeck remaining at 214,962,500 ordinary shares of £0.25 each
(approx. 69.9% of the issued ordinary share capital of the Company). All of
these shares remain subject to the terms of the lock-up for the remainder of 
its term.

Details of reorganisation

Mr Hochschild and Mr Beeck previously held their interests in the Company
through a jointly held holding company that also holds interests in other
business ventures. For purposes of the Disclosure Rules, Mr Hochschild was
deemed to own one hundred percent of such interests in the Company.
The effects of the reorganisation, which was implemented on 3 October 2007, 
for the purposes of the disclosure obligations under Disclosure Rule 3.1.2R 
were as follows:

•   Mr Hochschild's voting interest in the Company was reduced by 33,612,074
    ordinary shares (from 214,962,500 ordinary shares to 181,350,426 ordinary
    shares) in consideration for a transfer of Mr Beeck's interest in the
    holding company; and

•   Mr Beeck acquired a voting interest in 33,612,074 ordinary shares of the
    Company together with a cash sum.
