Canadian Zinc Corporation announced to provide an update on its collaboration project with Buchans Minerals Corporation in which the companies have agreed to jointly undertake a research program aimed at investigating the viability of developing their respective central Newfoundland Zn-Pb-Cu-Ag-Au deposits through a central milling facility. The objective of the research program is to determine the technical and economic viability of developing the companies' key deposits into producing operations by utilizing a central milling facility. The concept is based on the potential that collectively, the satellite deposits can be economically mined, pre-concentrated, trucked and then milled simultaneously or sequentially through a central mill.

Work completed to December 31, 2015 included diamond drilling to obtain fresh metallurgical samples from four of the seven VMS deposits. These included Canadian Zinc's Boomerang-Domino and Lemarchant deposits and Buchans Minerals'Bobbys Pond and Daniels Pond deposits. Drilling at the Boomerang-Domino deposit included twinning historic drillhole GA05-12 twice by wedging immediately above the mineralized zone.

Drilling at the Lemarchant deposit targeted the thick massive sulphide-barite zone and mineralized footwall zone intersected in historic drillhole LM10-43 with a new vertical drillhole (LM15-107). A single metallurgical sample, totaling 126 kg was prepared for the Boomerang deposit from the mineralized zone intersected by GA05-12A and GA05-12B. Two composite samples, one from the massive sulphide/barite zone (104 kg) and one from the footwall zone (43 kg) were prepared for the Lemarchant deposit from the mineralized zone intersected in LM15-107.
