Canada Zinc Metals - 2017 Akie Exploration Program Update

Vancouver, British Columbia, Canada – Wednesday, Au gust 30, 2017 – Canada Zinc Metals Corp.

(TSX Venture Exchange: CZX) is pleased to announce that the final two drill holes of the 2017 exploration

program have been completed for a total of 8 drill holes successfully drilled on the Cardiac Creek dep osit.

The 2017 Akie exploration program is now complete a nd the exploration and drilling crews have

demobilized from site.

The Company owns 100% of eleven, 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 Eas t and Mt. Alcock properties, extending northwest fr om

the Akie property for approximately 140 kilometres along 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, British Columbia, Canada.

The 2017 Akie exploration program commenced in June and utilized two diamond drill rigs. The drilling

focused on resource expansion and new target develo pment, building on the success of earlier drill

programs that have outlined a robust and high-grade zinc-lead-silver system in the central core of the

Cardiac Creek deposit.

2017 Drill Program Highlights

• Approximately 4,700 metres of HQ diamond drill cor e was completed in eight holes using 2

diamond drill rigs

• All drill holes intersected the target Cardiac Cre ek Zone with well mineralized intervals recovered

• First four holes targeted both the central core an d the up-dip strike extents of the high-grade core

• Two holes targeted the lower central core area at its known extents to the NW and the SE

• Final two holes focused on expansion of the known limits of the indicated resource

• Total of 1,100 samples, including standard QA/QC s amples, submitted to assay lab

• Program completed on schedule and under budget

Drillhole A-17-142 drillhole was collared into sili ceous shale of the Gunsteel Formation. Proximal Fac ies

pyrite mineralization was encountered in several ho rizons from 578.31 to 612.12 metres downhole. Two

distinct horizons of Cardiac Creek Zone mineralisat ion were encountered: an upper zone from 612.12 to

632.17 metres downhole that displays a progressive transition from sphalerite-rich banded mineralisati on

to mottled textured bands enriched in sphalerite an d galena. The lower Cardiac Creek Zone occurs from

642.17 to 655.75 metres downhole and is comprised o f approximately 85% mineralized interbeds. The

sulphide-bearing beds display prominent mottled textures enriched in sphalerite and galena. Disseminated

galena is present throughout the lower zone as well . A narrow interval of semi-massive sulphides was

intersected below the Cardiac Creek Zone and the ho le ended in Silurian Siltstones of the Road River

Group at a depth of 700.13 metres.

Drillhole A-17-143 was collared into siliceous shale of the Gunsteel Formation. Distal Facies mineralisation

consisting of interlaminated pyrite and nodular bar ite was encountered at a depth of 224.63 to 346.92

metres downhole. The Proximal Facies pyrite mineral ization was intersected at a depth of 346.92 metres

downhole, consisting of massive beds of very fine grained, dull brown pyrite, nodular barite, and rare bands

of light grey sphalerite. The Proximal Facies trans itions into Cardiac Creek Zone mineralization at a depth

of 352.69 metres downhole. The Cardiac Creek zone continued downhole to a depth of 382.95 metres and

is characterized by mottle-textured, thick, laminar sulphide beds enriched in pyrite, sphalerite and g alena

with lesser quartz and carbonate. Debris flows of t he Paul River Formation were intersected from 384.4 2

to 392.86 metres downhole. The hole was shut down i n Silurian Siltstones of the Road River Group at a

depth of 406.91 metres.

Approximately 400 metres of drilling was abandoned due to excessive downhole deviation. Those holes

were restarted with slightly different head orienta tions and then carried through to successful comple tion

intersecting the intended target areas.

Geological logging and sampling is now complete on all eight holes and a total of 1,100 samples, including

standard QA/QC samples, have been taken through the Cardiac Creek Zone. Samples from the first five

holes have reached the Acme Analytical Laboratories (a Bureau Veritas company) in Vancouver, BC; and

three holes are in transit from site to lab. The tr ue width estimates of each Cardiac Creek intercept are not

yet available but are being modeled and will be cal culated upon release of pending assay results. Assa ys

results from the first two holes are expected in ap proximately one week with the remainder following

thereafter.

Peeyush Varshney, CEO, commented: “We are very plea sed with the overall execution of the 2017 drill

program. We completed drilling on all selected targ ets and carefully managed resources to keep on

schedule and under budget. We look forward to annou ncing drill results over the coming weeks at a time

when the market fundamentals for zinc and lead cont inue to show remarkable strength and underpin a

robust price outlook.”

QA/QC

Canada Zinc Metals has implemented a rigorous quali ty assurance/quality control program at the Akie

property using best industry practices. All drill c ore is logged for geology, structure, veining, alte ration,

mineralisation, and geotechnical parameters. Sectio ns of sulphide mineralisation are marked for sampli ng

by a geologist and a series of standards, duplicate s and blanks are inserted into the sample stream fo r

QA/QC purposes. Prior to the cutting of samples, al l core boxes are photographed for due diligence and

record keeping purposes. The samples are split by a diamond saw, tagged and bagged and forwarded by

bonded carrier to Acme Labs (a Bureau Veritas Group Company) of Vancouver, BC, 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 le ad 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, BC with their OG46 analytical package

using aqua regia digestion and ICP-ES analysis. All remaining drill core is stored at the Akie explora tion

camp.

The Akie Zn-Pb-Ag Project

The Company’s flagship 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 ba ritic-

zinc-lead-silver SEDEX mineralisation 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 NI 43-101 compliant mine ral resource at Cardiac Creek, including an

indicated resource of 19.6 million tonnes grading 8 .2% zinc, 1.6% lead and 13.6 g/t silver (at a 5%

zinc cut-off grade) and an inferred resource of 8.1 million tonnes grading 6.8% zinc, 1.1% lead and

11.2 g/t silver (at a 5% zinc cut-off grade).

Ken MacDonald P.Geo., Vice President of Exploration , is the designated Qualified Person as defined by

National Instrument 43-101 and is responsible for the technical information contained in this release.
