ANTOFAGASTA MINERALS AUSTRALIA PTY LTD FARM-IN AGREEMENT, page-2

From the December 13 quarterly
CLERMONT COPPER GOLD PROJECT (QLD) As reported in the last quarterly activities report, Antofagasta plc, through a wholly owned subsidiary, withdrew from their farm-in over the Clermont Project (Figure 1) without earning an interest. Diatreme benefited from Antofagasta’s involvement in the search for large scale porphyry copper-style mineralisation at Clermont through expenditure in the order of $1.5M. The Company’s knowledge and understanding of the Rosevale Porphyry Corridor (RPC) has been significantly advanced through combined efforts with Antofagasta, and the Company plans to continue exploration for the sources of the widespread copper mineralisation within this corridor and in the district.
