About Abacus Mining & Exploration Corp.

Abacus is a mineral exploration and mine development company currently focused on copper and gold in British Columbia and Nevada. The company's main asset is a 20-per-cent ownership interest, together with KGHM Polska Mied SA (80 per cent), in the proposed Ajax copper-gold mine located southwest of Kamloops, B.C., which has undergone a joint provincial and federal environmental assessment process. On Dec. 14, 2017, a decision was made by the British Columbia Minister of Environment and Climate Change Strategy and the Minister of Energy, Mines and Petroleum Resources to decline to issue an environmental assessment certificate for the project. KGHM has recently reopened an office in Kamloops, B.C., to facilitate first nation, community and governmental engagement in order to advance the project toward a potential resubmission of the environmental application.

Abacus also owns a 100-per-cent interest in the Willow copper-gold property located near Yerington, Nev., and it controls the contiguous Nev-Lorraine claims subject to a 10-year lease agreement.
