Name of the Project
Moss mine gold/silver project – Phase III.

Location
Arizona, in the US.

Client
Northern Vertex Mining Corp.

Project Description
A preliminary economic assessment (PEA) has set out the technical and economic viability of extending the Moss mine to include resources in the company’s adjacent unpatented mining claims. This scenario includes surface disturbance and an expansion of the mine facilities onto federal public lands This will include an expanded heap leach pad to accommodate the additional mineralised material and an expanded waste-rock facility to accommodate the additional waste rock.

Exploitation of the Moss vein and adjacent stockworks will be done using openpit mining methods with a conventional drill-blast-load-haul mining fleet. The PEA envisages that all mining will be undertaken by a contract miner for the life of the mine. The PEA assumes that the Phase II flowsheet and processing methods will be used to process Phase III material. The Phase II plant, now under construction, incorporates three-stage crushing as was used in the pilot plant. The design is based on 350 d/y of operation. The nominal crushing and ore stacking tonnage will be 2 500 t/d for the first two months of operation, increasing to 3 500 t/d in month three, followed by a tonnage increase to 5 000 t/d from month five to the end of the mine life.
