Vancouver, BC -- May 15, 2017. Abacus Mining & Exploration Corporation ("Abacus" or the "Company") (TSXV:AME) wishes to provide an update on the Ajax Project's Environmental Assessment ("EA") review process within the context of a joint and coordinated federal and provincial review effort towards a streamlined process and timeline alignment. 

Resumption of EA Review Process 
On March 29, 2017, the operator of the Ajax Project, KGHM International ("KGHMI"), was notified by the British Columbia Environmental Assessment office ("EAO") that, as a result of the satisfactory completion of information and materials in response to issues raised by multiple stakeholders, and in fulfilment of the requirements related to Aboriginal and public consultation, it had lifted its suspension of the 180-day time limit for the application review. This suspension was originally requested by KGHMI to fulfill the requirements to the EAO's satisfaction. 

The resumption of the review process occurs at day 108 of the 180-day timeframe and is a positive development toward the feasibility of a final decision later this fall. 

EA Process next steps
The EAO also informed that, going forward, the Canadian Environmental Assessment Agency ("Agency") and the EAO have agreed to seek a greater level of coordination and to prepare a joint assessment report. This coordinated approach is expected to streamline the process and provide greater certainty of process through the alignment of timelines, ensuring that both jurisdictions consider the same information and avoid duplication. Throughout the period, the Agency and the EAO have acted in coordination on the Ajax Project, co-chairing a technical working group, participating in consultation with Aboriginal groups and coordinating public comment periods. 

To provide the process certainty for the remainder of the EA and to ensure federal-
provincial timeline alignment consistent with a coordinated process, the provincial review period will be extended by an additional 110 days. Inclusive of the extension will be a 30-day public comment period on the joint assessment report and any draft provincial EA Certificate conditions, as well as a 45-day period for provincial Ministers to make a decision as to whether to issue an EA Certificate for the Ajax Project. Hence the Application review phase is expected to conclude around late September 2017, and decisions from the provincial and federal governments are expected later in the fall. 

Community and First Nations Consultations
The goal of the Ajax Project is to be an integral member of the community through an open-door policy of continuous consultation and providing solutions which have resulted in numerous technical enhancements and design changes through the Application/EIS process that has improved the Project. One such major change is the new mine plan which concentrates mining activities in a central footprint to reduce emissions and dust. This has necessitated the relocation of the tailings storage facility to more than 5 kms southeast and no longer within Kamloops City limits; the facility has been redesigned from a dry stack tailings to a thickened tailings storage facility; the north rock storage facility has been relocated, including the mine processing plant and ore stockpiles more than 2 kms south of their formerly proposed locations; and the primary crusher will also move south of the pit, and approximately 3.5 kms from the closest city neighbourhood. 

Another recent example is in response to the Tk'emlups and Skeetchestn bands ("SSN") concerns over the preservation of a historic fish habitat. A new plan involves construction of a dam and connector channel, preservation of a spillway, and restoration of fish habitat by adding spawning gravel, in addition to creating a new access road, boat launch and recreational area for local fishers. 

Negotiations are ongoing with the City of Kamloops and the SSN towards a lasting partnership which the Ajax team views as an essential opportunity to invest in the future of Kamloops and nearby communities.
