Constantine Intersects 4.6 Meters of 0.52% Copper and 4.65% Zinc in 335 Meter Step-out on RW Zone at Palmer Project, Alaska

Vancouver, September 25, 2019 - Constantine Metal Resources Ltd. (TSXV: CEM) (OTCQX: CNSNF) ("Constantine" or the "Company") is pleased to report assay results for a drill hole testing the depth extension of the RW Zone at its Palmer Joint Venture Project, Alaska ("Palmer" or the "Project"). The RW Zone (which includes the RW West, RW East and RW Oxide Zones) is located in the Palmer Deposit area and within the same folded mineralized horizon that hosts the main South Wall Zones. Expansion of the RW Zone is a priority for the Company as the RW Zone is near to planned mining infrastructure but was not included in the Company's recently released Preliminary Economic Assessment (See Company Press Release dated June 3^rd, 2019).

Drill hole CMR19-140 was designed to test the open down-dip and down-plunge extension of the RW West Zone and intersected massive baritic sulphide mineralization (Table 1). The new intercept represents a significant 335 meter step-out of the mineralized zone (Figure 1). The zone is open to further expansion along strike (east and west) and at depth.

"We are very encouraged by this new intersection at the RW Zone, which shows the potential to expand the RW Zone through further targeted step-out holes," said President & CEO Garfield MacVeigh. "This could ultimately lead to the inclusion of the RW Zone in future economic studies on Palmer and further enhance the Project."

Mineralization in drill hole CMR19-140 is very similar in character to previous RW Zone drill hole intersections, which were last drilled in 2014. The nearest up-dip intersection is hole CMR14-67 which returned 3.9 meters averaging 5.11% zinc, 0.19% copper, 92.5 g/t silver and 0.37 g/t gold. The RW West Zone previously had an approximate maximum true thickness of 6 meters, a strike length of 375 meters, and a dip length of 325 meters (based on mineral resource wireframes). The zone remains open both up- and down-dip, and along strike.

The Company completed a total of 3,165 meters of drilling in eight holes (CMR19-135 to CMR19-142) on the Palmer Project in 2019. Holes targeted step-outs of: 1) the RW West Zone, 2) the AG Zone, and 3) a previously untested sub-ice geophysical target to the west of the HG prospect. All assays have been received.

The AG Zone drilling to date shows that the deposit remains open up-plunge to the southeast towards the JAG prospect and towards the Waterfall prospect, 1.2 kilometers to the northwest.

At the sub-ice geophysical target, VMS-style barite-zinc mineralization in drill hole CMR19-142 returned 1.3% zinc and 8.52% barite from 378.7 to 379.2 meters with extensive strong pyritic footwall style alteration. . These results are highly encouraging for follow-up of this target and for the nearby untested HG prospect.

Update on Permitting

Constantine's Waste Management Permit (see Constantine news release July 31, 2019) has been remanded to the Alaska Department of Environmental Conservation ("DEC") staff for further review. The remand is due to a 9th Circuit Court Decision related to "the Hawaiian Wildlife case" that is currently before the Supreme Court that may change the way that US Environmental Protection Agency ("EPA") and DEC permit water discharges in the United States. Alaska has joined 18 other States in supporting EPA's and DEC's current permitting process and asking that the 9^th Circuit's decision in Hawaii Wildlife be reversed.

About the Palmer Project

Palmer is a high-grade volcanogenic massive sulphide-sulphate (VMS) project located in a very accessible part of coastal Southeast Alaska, with road access to the property and within 60 kilometers of the year-round deep-sea port of Haines. Mineralization at Palmer occurs within the same belt of rocks that is host to the Greens Creek mine, one of the world's richest VMS deposits.

A Preliminary Economic Assessment presents a low capex, low operating cost, high margin underground mining operation with attractive environmental attributes (see news release dated June 3, 2019). Exploration has resulted in the discovery of the new AG deposit and continued to grow the resource base to its current estimated size of 4.68 million tonnes indicated grading 5.23 % zinc,1.49 % copper, 30.0 g/t silver, 0.30 g/t gold and 9.6 million tonnes inferred grading 4.95 % zinc , 0.59 % copper, 69.3 g/t silver, 0.39 g/t gold. VMS deposits are known to occur in clusters, and with at least 25 separate base metal and/or barite occurrences and prospects on the Project, there is abundant potential for discovery of multiple deposits.

About the Company

Constantine is a mineral exploration company led by an experienced and proven technical team with a focus on the Palmer Project being advanced as a joint venture between Constantine (51%) and Dowa Metals & Mining Co., Ltd. (49%), with Constantine as operator. The plan is to continue to expand and discover new resources while the project is being advanced towards feasibility. The Company will continue to evaluate new prospects for value added opportunities.

Management is committed to providing shareholder value through discovery, meaningful ‎community engagement, environmental stewardship, and responsible mineral exploration and ‎development activities that support local jobs and businesses.

Notes:

Samples of drill core were cut by a diamond blade rock saw, with half of the cut core placed in individual sealed polyurethane bags and half placed back in the original core box for permanent storage. Sample lengths typically vary from a minimum 0.3 meter interval to a maximum 1.5 meter interval, with an average 1.0 to 1.5 meter sample length. Drill core samples were shipped by transport truck in sealed woven plastic bags to ALS Minerals laboratory facility in Kamloops, BC for sample preparation and North Vancouver, BC for analysis. ALS Minerals operate according to the guidelines set out in ISO/IEC Guide 25. Gold was determined by fire-assay fusion of a 30 g sub-sample with atomic absorption spectroscopy (AAS). Various metals including silver, gold, copper, lead and zinc were analyzed by inductively-coupled plasma (ICP) atomic emission spectroscopy, following multi-acid digestion. The elements silver, copper, and zinc were determined by ore grade assay for samples that returned values >10,000 ppm by ICP analysis. Barium (BaO) analysis utilized lithium borate fusion into fused discs for XRF analyses, with BaO converted to BaSO4 (barite) using a conversion factor of BaO x 1.52217. Density measurements were determined at the project site by qualified Constantine personnel on cut core for each assay sample.

The 2019 exploration program for the Palmer project is managed by Darwin Green, P.Geo., the Company's Vice President Exploration for Constantine Metal Resources Ltd. and a qualified person as defined by Canadian National Instrument 43-101. Mr. Green has reviewed the information contained in this news release and has also verified the analytical data for drill core samples disclosed in this release by reviewing the blanks, duplicates and certified reference material standards and confirming that they fall within limits as determined by acceptable industry practice. The analytical results have also been compared to visual estimates for the base metals to check for any obvious discrepancies between analytical results and the visual estimates.

The Palmer Project hosts the Palmer Deposit and the AG Zone Deposit with a total consolidated mineral resource of 4.68 million tonnes of 10.2% Zinc Equivalent ("ZnEq") in the Indicated category and 9.59 million tonnes of 8.9% ZnEq in the Inferred category. ZnEq is based on assumed metal prices and 100% recovery and payable for Cu, Zn, Pb, Ag and Au. ZnEq equals = ($66 x Cu% + $25.3 x Zn% + $22 x Pb% + $0.51 x Ag g/t + $40.19 x Au g/t) / 25.3. Assumed metal prices are US$3.00/lb for copper (Cu), US$1.15/lb for zinc (Zn), US$ $1.00/lb for lead, US$1250/oz for gold (Au), US$16/oz for silver (Ag). Barite (BaSO4) was not included in the Cut-off determination or reported ZnEq. Mineral resources as reported are undiluted. Mineral resource tonnages have been rounded to reflect the precision of the estimate. Readers are cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability.
