Altona Mining : Cloncurry Copper Project Transaction Status

3 July 2017 ASX: AOH, FSE: A2O

CLONCURRY COPPER PROJECT TRANSACTION STATUS

Altona Mining Limited ("Altona" or "the Company") has agreed, subject to conditions, with Sichuan Railway Investment Group Co., Ltd ("SRIG") for SRIG to fund the Cloncurry Copper Project in north- west Queensland through its Hong Kong subsidiary, China Sichuan International Investment Limited ("CSII").

The approval of the transaction by the Australian Foreign Investment Review Board ("FIRB") is a con- dition precedent to execution of a Subscription Deed. FIRB approval was received on 11 May 2017.

The approval of the State-owned Assets Supervision and Administration Commission of the State Council of the Sichuan Province of the People's Republic of China ("SASAC") is required for SRIG, through CSII, to make the investment in the project and it is a condition precedent to executing a Sub- scription Deed.

SRIG have advised that before SASAC can complete its approval process, SASAC requires advice of regulatory amendments from the Sichuan Provincial Government.

A tragic landslide occurred on 24 June 2017 in Sichuan Province which resulted in a major loss of life. Senior SRIG staff and Provincial Government officials have been called to the site of the landslide and this has delayed the Project approval process from being completed. CSII has advised Altona that it expects to receive formal approval from SASAC by mid July.

As all approvals must be received prior to execution of the Subscription Deed, the delay to the receipt of formal approval from SASAC is such that the parties have agreed that the last date for execution of the Subscription Deed will be extended from 30 June 2017 to 21 July 2017. The last date for closing of the transaction will also be extended from 31 July 2017 to 11 August 2017.

The parties have made good progress towards finalising the Conditions Precedent to closing the transaction and Altona has completed most of its Conditions Precedent.
