Abacus Mining Announces New Ajax Project Site Plan

Update on Permitting Progress and 2014 Work Programme

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 29, 2014) - Abacus Mining and Exploration Corporation ("Abacus" or the "Company") (TSX VENTURE:AME) announces that KGHM International Ltd., a wholly owned subsidiary of its joint venture partner and operator of the Ajax Project near Kamloops, B.C. has made modifications to the site plan wherein several of the proposed mine's industrial facilities have been moved farther from the City of Kamloops.

The new site plan represents an important adjustment to the Ajax Project as it concentrates mine activities to reduce the potential for adverse impacts from industrial activity to the city, nearby residents and other public infrastructure while optimizing the value of the project.

It is envisioned that these changes, brought about in consultation with the neighbouring communities and by listening to their concerns over several months, will have a positive effect on the timely finalization of the Environmental Assessment (EA) Application/EIS and resulting approval from the regulatory agencies

The key changes include:

• Redesign of the tailings storage facility from the previously proposed dry stack tailings storage to a more proven wet tailings technology. The tailings storage facility will be located closer to the mine operations.
• Relocation of a waste rock storage facility, the mine processing plant, primary crusher and temporary ore stockpiles. These sites, formerly situated inside City of Kamloops limits, will now be located more than 3.5 kilometers from the nearest city neighbourhoods and outside municipal boundaries.

The concentrated mine footprint means fewer roads, haul trucks will drive shorter distances, which are designed to considerably decrease on-site truck traffic, emissions and dust. Further details of the new general arrangement are available at www.ajaxmine.ca. For a brochure on the Ajax Project including a map of the new site plan, please follow this http://media3.marketwire.com/docs/ame0529ajax.pdf.

Permitting Timeline

The EA Application/EIS is expected to be submitted at the end of the first quarter in 2015 whereupon a 30-45 day assessment period will determine whether the application will be received for formal review. This review process is expected to take approximately one year in parallel with which the MEMA permit application will be submitted. This schedule will enable mine construction to begin as early as the second quarter of 2016 with production commencing towards the end of 2018. A number of potential delays associated with material changes or additions to the AIR/EIS guidelines may prolong this schedule. Other risks and uncertainties are listed in the Company's regulatory filings on Sedar (www.sedar.com) or its website (www.amemining.com).

2014 Work Programme

A major work programme is planned for 2014 consisting of various permitting activities, detailed engineering work, metallurgical test work, optimization studies and exploration and condemnation drilling. The objective of the exploration drilling programme, estimated to comprise 13,500 metres, is to identify potentially economic mineral resources close to the Ajax mining complex for future resource definition, as well as to test several highly-prospective regional targets outside the Ajax area, which resources could add significant value to the project.

Abacus currently has $16 million in the Ajax escrow account that is anticipated to be sufficient for its proportionate share of the cash calls for the year's programme.
