Proposed Project and Location

Activities:
The Palmer Project (project) operated by Constantine Mining LLC is a copper-zinc-silver-gold-barite prospect in the advanced exploration stage. The surface disturbance proposed in this Plan of Operations will occur on Mental Health Trust lands. Activities include; 1) excavating approximately 2,012 meters of underground ramp to provide a drill platform for exploration and provide access to gather additional geotechnical and hydrogeological data, 2) completing approximately 30,000 meters of underground exploration drilling, 3) placing approximately 70,000 cubic meters of non-PAG development rock on the surface, 4) constructing and operating two settling ponds for underground seepage water, prior to discharge through the land application disposal system (LAD), 5) constructing a buried, land application disposal system to dispose of underground seepage water, The LAD design will be submitted to ADEC for approval separate from this Plan of Operations, 6) constructing ancillary facilities used in support of the underground exploration program including installation of a generator, air compressor, fuel tanks, mine air ventilation fan(s) etc. These activities do not deviate from prior approvals.

The overall program is directed at further evaluation of the Palmer Deposit. The long-term project objective is to continue the evaluating for as long as warranted by the technical results, and to methodically assess the technical and economic viability of developing an underground mine. The entire surface disturbance proposed in this Plan will occur on Trust surface lands, where the Trust also owns the subsurface estate. Constantine has an Upland Mining Lease.

Location:
The Palmer Project (project) is located within the Porcupine Mining District in the Haines Borough. Roads connect the project area to the village of Klukwan, approximately 17 miles to the east, and the coastal town of Haines, approximately 35 miles to the southeast.
