Abacus Announces Filing of Updated Feasibility Study for Ajax Copper-Gold-Silver Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 23, 2016) - Abacus Mining & Exploration Corporation ("Abacus" or the "Company") (TSX VENTURE:AME) announces that the updated feasibility study (the "updated FS") for the Ajax copper-gold-silver deposit entitled "Ajax Project, NI 43-101 Technical Report, Feasibility Study Update" dated February 19, 2016 has been filed on Sedar (www.sedar.com) and the Company's website at www.amemining.com.

The updated FS, prepared in accordance with Canadian National Instrument 43-101 by a consortium of independent consultants under the direction of M3 Engineering and Technology Corp., supersedes the Feasibility Study of January 6, 2012 and incorporates an updated reserve and significantly updated engineering. In addition, several significant changes in the project scope and layout have yielded positive economic, processing and environmental impacts for the Project. (See Abacus news release dated January 13, 2016).

The mine plan is based on the extraction of 426 Mt of ore containing 0.29% copper, 0.19 g/t gold and 0.39 g/t silver. This compares to the 2012 Feasibility Study of a reported 503 Mt of reserves containing 0.27% copper and 0.17 g/t gold. The Mineral Reserve Estimate contained in the updated FS is summarized as follows:

Notes: 1. CIM Definitions were followed for Mineral Reserves. 2. Mineral Reserves are estimated at an NSR cut-off of $7.10. 3. Mineral Reserves are estimated based on long term metal prices of US$3.21/lb Cu, US$1200/oz. Au, and US$17/oz. Ag. 4. Inferred blocks were included as waste blocks in generating the economic pit shell. 5. Process recoveries for the six common metallurgical zones are included in the NSR estimation. 6. Tonnages and grades are rounded to reflect the accuracy of the estimate, and numbers may not add correctly due to rounding.

Mine life is calculated to be 18 years at an average nominal processing rate of 65,000 t/d and an overall stripping ratio of 2.65:1, waste to ore. Based on the contained metal content of 1.2 Mt (2.7 billion lbs) of copper, 2.6 million oz of gold and 5.3 million oz of silver, average annual production is estimated to be 58,000 tonnes of copper and 125,000 ounces of gold in concentrate.
