CANADA ZINC METALS CONTINUES TO INTERSECT HIGH GRADE MINERALISATION WITH 10.79% ZN+PB OVER 6.9 METRES IN DRILL HOLE A-15-131
Canada Zinc Metals Corp. has released new assay results for drill holes A-15-130 and A-15-131, which focused on expanding the current indicated resource as well as the known extents of the high-grade zinc-lead-silver system in the central core of the Cardiac Creek deposit on the Akie property.
The company owns 100 per cent of 11, large, contiguous property blocks that comprise the Akie and Kechika Regional projects. The company's flagship Akie project is host to the Cardiac Creek deposit. The Kechika Regional project includes the Pie, Yuen, Cirque East and Mt. Alcock properties extending northwest from the Akie property for approximately 140 kilometres along the strike of the highly prospective Gunsteel formation shale, the main host rock for known SEDEX zinc-lead-silver deposits in the Kechika Trough of northeastern British Columbia. These projects are located approximately 260 kilometres north-northwest of the town of Mackenzie, B.C., Canada.
Drill assay results for 2015
The 2015 Akie drill program was concluded in late September with a total of 5,350 metres drilled in eight drill holes. All results have now been received. Previous results were released on Sept. 2, 2015, Oct. 22, 2015, and Nov. 12, 2015, and are summarized in the table. Drill holes A-15-128 and A-15-129 were both abandoned at shallow depths due to excessive downhole deviation and successfully completed as drill hole A-15-130.
A-15-130
This hole tested the dip extents of the high-grade core with a targeted pierce point located approximately 75 metres downdip of drill hole A-07-43.
The hole collared into Gunsteel formation shale encountering several intervals of distal facies mineralization down to a depth of 570.53 metres. Proximal facies mineralization was encountered from 570.53 to 601.00 metres and is characterized by thickly bedded, fine-grained pyrite interbedded with nodular barite and thin bands of fine-grained sphalerite. The Cardiac Creek zone extends from 601.00 to 626.38 metres and is characterized by fine-grained sphalerite interbedded with mottled textured sphalerite-quartz-carbonate-galena, and fine-grained, laminar pyrite. Galena mineralization is concentrated within the bands of mottled sulphides and disseminated proximal to them. Sphalerite banding generally increases in frequency and thickness toward the bottom of the zone. A shale interbed from 626.38 to 637.43 metres separates the Cardiac Creek zone from the Footwall zone. The Footwall zone from 637.43 to 649.72 metres has abundant sphalerite mineralization of similar character to the Cardiac Creek zone but it decreases in frequency downhole while laminar pyrite mineralization increases. The hole ended in calcareous siltstone of the Road River group at 690.08 metres.
Drill hole A-15-130 contains an extensive envelope of mineralization present from 596.59 to 649.72 metres grading 4.12 per cent combined zinc-lead and 7.01 grams per tonne silver over a true width of 34.03 metres. This envelope contains the Cardiac Creek zone from 601.00 to 625.75 metres which returned 6.77 per cent combined Zn-Pb and 10.51 g/t Ag over a true width of 15.82 metres. Higher-grade intervals include 8.35 per cent combined Zn-Pb and 12.84 g/t Ag over a true width of 12.15 metres from 606.75 to 625.75 metres. The Footwall zone from 637.43 to 649.72 metres returned 3.32 per cent combined Zn-Pb and 6.76 g/t Ag over a true width of 7.91 metres, and included a higher-grade interval of 10.48 per cent combined Zn-Pb and 15.41 g/t Ag over a true width interval of 1.79 metres from 637.43 to 640.22 metres.
A-15-131
Drill hole A-15-131 targeted the updip extension of the high-grade core by infilling between holes A-14-114, A-08-58, A-08-54, A-94-11 and A-08-57, with an average separation from each of approximately 75 metres.
The hole collared into Gunsteel formation shale and several repetitive, thick intervals of distal facies mineralization and interbedded shale before encountering the Cardiac Creek zone. Proximal facies mineralization was not present in this hole. The Cardiac Creek zone was intersected from 266.16 to 288.36 metres and represented by thick beds of laminar-bedded sulphide mineralization. High-grade sections comprise fine-grained sphalerite banding and mottled textured sphalerite-quartz-carbonate-galena bands. The Cardiac Creek zone is underlain by sulphides intercalated with thick beds of massive barite from 288.36 to 297.00 metres. A small interval of debris flow occurs just above the Road River contact and the hole was finished at 322.17 metres in Road River group siltstone.
The Cardiac Creek zone returned 6.64 per cent combined Zn-Pb and 10.89 g/t Ag over a true width of 21.17 metres from 266.00 to 289.53 metres. This includes higher-grade intervals such as 9.83 per cent combined Zn-Pb and 16.00 g/t Ag over a true width of 9.74 metres, and 10.79 per cent combined Zn-Pb and 15.46 g/t Ag over a true width of 6.91 metres.
The results from A-15-130 and A-15-131 are shown in the table.

* Previously reported 2015 results.
Peeyush Varshney, president and chief executive officer of the company, commented: "The 2015 drilling has expanded the known limits of the high-grade core in the downdip direction by approximately 75 to 100 metres. Excellent results such as 17.06 per cent combined Zn-Pb over 12.98 metres in A-15-121 and 17.20 per cent combined Zn-Pb over 11.09 metres in A-15-124 were highlights of the drill program. Furthermore, drill holes A-15-124, A-15-127 and A-15-130 have demonstrated that the deposit is still open at depth and warrants additional downdip drilling. Over all, we are very pleased with the success of the 2015 Akie drilling and continue to see the opportunity for expansion of the deposit, something we will focus on as we update the geological and resource models, and plan for the next step in definition drilling."
Quality assurance/quality control
Canada Zinc Metals has implemented a rigorous quality assurance/quality control program at the Akie property using best industry practices. All drill core is logged for geology, structure, veining, alteration, mineralization and RQD. Sections of sulphide mineralization are marked for sampling by a geologist, and a series of standards, duplicates and blanks are inserted into the sample stream for QA/QC purposes. Prior to the cutting of samples, all core boxes are photographed for due diligence and record-keeping purposes. The samples are split by a diamond saw, tagged and bagged, and forwarded to Acme Labs (a Bureau Veritas Group Company) of Vancouver, B.C., for analysis. Documentation recording the chain of custody is kept for each shipment.
Assays for zinc, lead and silver are obtained using Acme Labs AQ270 analytical package with sample digestion using aqua regia solution followed by ICP-ES and ICP-MS analyses. Barium content is determined by Acme Labs LF300 analytical package using LiBO2/LiB4O7 fusion and ACS grade nitric acid followed by ICP-ES analysis. Overlimit values of lead and zinc are rerun using Bureau Veritas AQ371 analytical package using a hot aqua regia solution followed by ICP-ES analyses. Check assays on drill pulps are routinely conducted by ALS Minerals of North Vancouver, B.C., with its OG46 analytical package using aqua regia digestion and ICP-ES analysis. All remaining drill core is securely stored at the Akie exploration camp.
The Akie Zn-Pb-Ag project
The Akie property is situated within the Kechika Trough, the southernmost area of the regionally extensive Paleozoic Selwyn basin, one of the most prolific sedimentary basins in the world for the occurrence of SEDEX zinc-lead-silver and stratiform barite deposits.
Drilling on the Akie property by Canada Zinc Metals since 2005 has identified a significant body of baritic-zinc-lead-silver SEDEX mineralization known as the Cardiac Creek deposit. The deposit is hosted by siliceous, carbonaceous, fine-grained clastic rocks of the Middle to Late Devonian Gunsteel formation.
The company has outlined a National Instrument 43-101-compliant mineral resource at Cardiac Creek, including an indicated resource of 12.7 million tonnes grading 8.4 per cent zinc, 1.7 per cent lead and 13.7 g/t silver (at a 5-per-cent-zinc cut-off grade), and an inferred resource of 16.3 million tonnes grading 7.4 per cent zinc, 1.3 per cent lead and 11.6 g/t silver (at a 5-per-cent-zinc cut-off grade).
