Joint Venture Next Steps

Abacus delivered the final Feasibility Study to KGHM in late December 2011 in accordance with the provisions of the Joint Venture Shareholders' Agreement of October 12, 2010. KGHM will have 90 days to acquire a further 29% in the Joint Venture company for a cash consideration equal to 29% of the Proven and Probable copper equivalent reserve in the FS, to a maximum of US$35 million, towards use by Abacus for its share of project capital.

In the event that KGHM chooses not to increase its interest in the joint venture, Abacus then has 90 days to elect to purchase KGHM's 51% interest for US$37 million, and 90 days thereafter to close on this purchase. Should Abacus choose not to purchase KGHM's interest in its entirety, Abacus' interest in the Joint Venture can be increased to 51% by paying approximately US$1.5 million to KGHM.

The technical information in this news release has been reviewed and approved by Dave Laudrum, P.Geo., Abacus's Chief Geologist and qualified person for the Ajax Project within the meaning of National Instrument 43-101.
