Economic Assessment
The metallurgical test programs are being followed-up with a Process Simulation and Cost Assessment model (AACE Class V – order of magnitude / conceptual assessment) to evaluate and identify the key factors impacting the operating economics of a centralized processing concept for the production of the base metal concentrates from the various base metal deposits in central Newfoundland .
Results from the conceptual economic assessment will be used to help optimize future exploration and development plans, by focusing on key factors that are critical to assessing the economic potential and viability of developing the central Newfoundland deposits through a centralized milling facility.
The overall research programs are partially funded by the Research & Development Corporation of Newfoundland and Labrador ("RDC") through the GeoEXPLORE Industry-led program and are scheduled to be completed in December, 2016.
Central Newfoundland Exploration Work
As part of its 2016 exploration program, Canadian Zinc is undertaking ground geophysical surveys including magnetics, gravity, electromagnetics ("EM") and borehole EM on a number of high priority Cu-Pb-Zn-Ag-Au target areas on its South Tally Pond and Tulks South properties.
At the South Tally Pond property, five priority targets in the Lemarchant Deposit area are being evaluated by ground and borehole EM and two priority targets are being evaluated at the Lost Lake prospect located 6 kilometres northeast of the Lemarchant Deposit.
