About Abacus

Abacus is a mineral exploration and mine development company with a feasibility stage copper-gold project located in the Ajax Mining Camp near Kamloops, B.C. The Ajax copper-gold project is a joint venture between Abacus Mining & Exploration Corp. and KGHM Polska Miedz S.A. (“KGHM”) through KGHM Ajax Mining Inc. (“KGHM Ajax”) currently owned 49% by Abacus and 51% by KGHM.

On December 21, 2011 Abacus announced robust feasibility study results supporting production of a total of 2.5 billion lbs of copper and 2.28 million ozs of gold in concentrate, or an average of approximately 109 million lbs of copper and 99,000 ozs of gold annually, over a 23 year mine life. The proposed mine plan envisages a conventional open pit operation processing 60,000 tonnes per day or 21.9 million tonnes per year of ore. [see Report titled “Ajax Copper/Gold Project – Kamloops, British Columbia Feasibility Study Technical Report” by Wardrop (a Tetra Tech Company) dated January 6, 2012 (“FS”)]

Pursuant to the Joint Venture Shareholders’ Agreement among Abacus, KGHM and KGHM Ajax, KGHM has 90 days to acquire a further 29% in KGHM Ajax for cash consideration equal to 29% of the proven and probable copper equivalent reserves as defined 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.
