NORTHWEST TERRITORIES – Vancouver-based Canadian Zinc Corp. is drilling and taking chip samples from underground at its Prairie Creek zinc-lead development project.
Chip sampling of the Stockwork zone on the 930 level returned composite grades of 14.2% Zn, 5.6% Pb and 119 g/t Ag across a true width of 4.4 metres and a strike length of 71.8 metres. The area has been named the Northwest drift.
Resources in the Stockwork zone were released in March 2015. The zone has an estimated 1.4 million indicated tonnes at 7.1% Zn, 4.0% Pb and 63 g/t Ag. The inferred portion is 790,000 tonnes grading 4.8% Zn, 4.0% Pb and 61 g/t Ag.
Diamond drilling in the lower part of the Main quartz vein (MQV) intersected good grades in three separate holes, with the best hole returning 3.95% Zn, 14.82% Pb and 377 g/t Ag over an estimated true width of 2.6 metres. The intersection was made about 300 metres vertically below the existing workings.
The Prairie Creek mine has total measured and indicated resources of 6.59 million tonnes grading 10.2% Zn, 9.5% Pb and 147.0 g/t Ag. The inferred portion is 7.08 million tonnes at 11.7% Zn, 9.6% Pb and 177.0 g/t Ag.
