NEWS RELEASE

CONSTANTINE ACQUIRES OPTION ON YUMA KING COPPER-GOLD

PROPERTY IN SOUTHWEST ARIZONA

(Vancouver) Constantine Metal Resources Ltd. (TSX Venture- CEM) (“Constantine” or the “Company”) is pleased to announce that it has signed a binding letter agreement (the “Agreement”) to acquire an undivided 100% interest in the Yuma King Copper-Gold property (the “Property”) consisting of 295 federal mining claims (3905 hectares). The Property represents a portion of the total 495 claim Yuma King property, located in La Paz County Arizona, USA. Constantine retains the right to a 50% interest in any agreement on the remaining 200 claim portion of the Yuma King property subject to certain obligations.

The Property is located 93 miles (153 kilometers) northwest of Phoenix, Arizona and about 20 miles (32 kilometers) southeast of Constantine’s previously announced Bouse Cu-Au property acquisition. The principal exploration targets are the Yuma Mine copper-gold skarn mineralization and copper-molybdenum porphyry style mineralization, associated with phases of an early Jurassic porphyry system. An early Jurassic rhenium-osmium molybdenite age date at Yuma King indicates a similar age to the Bisbee porphyry copper and skarn deposit in SE Arizona (S. Keith, MagmaChem Exploration Inc, personal communication).

“The most striking feature of this Property are the abundant widespread prospects centered around the historical Yuma mine and its high-gradecopper-gold skarn mineralization” stated Garfield MacVeigh, President and CEO of Constantine. “The underground Yuma mine is open for expansion with widespread untested skarn targets highlighting the potential. Past drilling has shown an association with a large untested copper-moly porphyry system hosted by a carbonate rich section of Paleozoic stratigraphy which will be evaluated. The greater Yuma King property hosts a variety of additional targets that include small scale past producing black shale/mafic- dyke hosted high-grade gold, various other gold prospects, intrusive hosted past producing tungsten deposits and graphite-graphene bearing black shales.”

The Property includes the past producing underground Yuma copper-gold mine that saw intermittent production between 1940 and 1963 and is reported to have produced 8,728 short tons at a grade of 2.65% copper, 0.03 oz/t (short ton) gold and 0.62 oz/t silver. A 2005 NI43-101 technical report (Russell, 2005) estimated an inferred resource of 357,560 to 536,985 short tons of combined oxide-sulphide grading 3.03% copper, depending upon estimated average thickness of the unmined mineralization in the underground workings of the historic Yuma mine. The Company is not treating this historical resource estimate as a current resource.

More recent exploration at Yuma King has resulted in the discovery of a significant northern extension of the Yuma mine skarn mineralization and new copper-molybdenum style porphyry mineralization that are prime exploration targets that need to be followed up with geophysics and drilling.

In 2006, the first surface drill program to test the Yuma Mine skarn mineralization encountered significant oxidized copper-gold skarn mineralization and established the first indication of Cu- Mo porphyry potential (Table 1). The drilling was completed from 5 drill sites over a distance of approximately 2,500 feet to the east of the historic mine portal. A 2011 drill hole, AV11-01, intersected the edge of the down dip extension of the Yuma mine skarn, 1,200 feet northeast of the historic mine workings.

Yuma King Geology and Exploration Overview

The Yuma King property is in a region of complex structural geology involving episodes of thrust deformation and mid-Tertiary,low-angle,detachment-style faulting with multiple mineralized environments and igneous intrusions ranging in age from Proterozoic(?) and Jurassic through Cretaceous. The extensive Yuma Mine skarn replacement horizon hosted by Paleozoic carbonates, in addition to porphyry style Cu-Mo mineralization occur within the Yuma Mine thrust plate in association with Early Jurassic aged intrusions in the northern portion of the Yuma King property.

From 2003, surface exploration work completed by MagmaChem Exploration, Inc. includes geological mapping, extensive surface rock chip sampling, underground sampling at the Yuma King mine and a limited magnetic geophysical survey. In 2005, Big Bar Gold completed a historical NI 43-101 resource estimate of the Yuma King mine with historical underground mine sampling information (Russell, 2005).

In 2006, Big Bar Gold conducted the first ever surface drill program (19 drill holes, 10,785 ft) at the Yuma mine site from five (5) drill sites with several angled drill holes from each site. The program tested the Yuma Mine copper-gold-magnetite skarn in the immediate area of the historic Yuma mine site from drill site YK01 with all 4 drillholes encountering significant oxide copper- gold skarn mineralization (see Table 1).

Drilling at drill sites YK02, YK03, YK04 and YK06 also encountered copper oxide and sulphide skarn and copper-molybdenum-gold porphyry mineralization extending over a distance of approximately 2500 feet to the east of the Yuma mine portal (see Table 1). Sixteen of the nineteen drillholes reported intercepts of copper mineralization greater than 0.1%.

In 2011, VANE Minerals completed drillhole AV11-01, designed to test for the down dip extension to the Yuma Mine copper-gold skarn mineralization in an area of a strong magnetic anomaly. The drillhole intersected 90 feet of copper bearing skarn mineralization (see Table 1) that assayed 0.31% copper, 0.03% molybdenum, 101 ppb gold and 288 ppb rhenium and is interpreted to have encountered a down dip edge of the high-grade Yuma Mine skarn corridor. The mineralization was intersected approximately 1200 feet to the northeast of the projected trend and plunge of the Yuma Mine mineralization and with molybdenum porphyry mineralization highlight the main porphyry potential to the north.

The 2006 and 2011 drilling programs show Yuma mine mineralization extending 1,200 feet (365 meters) north and approximately 2,500 feet (762 meters) east of the Yuma mine portal.

Other Prospective Exploration Areas

Yuma Mine Skarn Extensions(West Central Skarn, Parking Lot Skarn, North Gold Prospect)

Extensions of the Yuma mine skarn horizon occur as two separate magnetite skarn areas approximately 1.2 kilometers west-southwest of the Yuma Mine. Five historic rock grab samples from the West-Central Skarn area contained 0.034 to 1.44 ppm gold and 0.015% to 1.34% copper. Six rock grab samples collected by Constantine from the Parking Lot Skarn ranged from 0.017 to 1.125 ppm gold with copper ranging from 0.05% to 2.22%.

The North Gold prospect, 900 feet (275m) southwest of the West- Central Skarn is hosted in highly altered and mineralized porphyry with four historic rock grab samples containing 0.34 ppm to 9.98 ppm gold.

Quartzite Gold Prospects(East Gold, Gold Tunnel, High Graders Tunnel, Horse Trail Pits)

Quartz-gold-iron oxide mineralization is present as disseminations and high-gradelow-angle vein zones within shears in a Cambrian quartzite unit (Bolsa Quartzite) that has been thrust over the Devonian-Mississippian carbonate section that hosts the copper-bearing magnetite skarns. Historic rock samples from the four prospect areas highlight a consistent association of gold mineralization with the basal portion of the quartzite. The four prospects all occur within a triangular area measuring 362m x 200m x 225m with historic grab sample results shown below.

Constantine collected two rock grab samples from the base of the quartzite at the Gold Tunnel prospect near drill site YK02 that assayed 1.525 ppm and 1.7 ppm gold.

Yellowbird Black Shale-Mafic Dyke Gold Prospects

There are numerous complex quartz-carbonate veined zones associated with highly deformed black slates intruded by mafic dykes in the southern part of the Yuma King Property that are recognized by numerous pits and tunnels with dump piles of quartz-carbonate veining. The Glory Hole Mine discovered in 1909 is famous for producing very high-grade gold in this geological setting and has spectacular surface expressions of quartz-siderite veins and vein breccia “blow-outs”. The intensive veining at the Glory Hole appears to be hosted mainly by an east-west trending mafic dyke intruding the Yellowbird black slates. Extensive old workings exist at the Glory Hole, but there is no evidence of previous drilling activity.

Road Tunnel Gold Prospect

Multiple stacked quartz-carbonate veins hosted in quartz-carbonate-muscovite (sericite) schist have been accessed by pits and short tunnels. Four historic rock grab samples assayed 0.003 oz/t gold to 0.174 oz/t gold.

Tungsten Prospects

Tungsten prospects include shear-zone hosted tungsten, such as at the historic Three Musketeers and Jewel Anne mines, and greisen tungsten mineralization associated with a Late Cretaceous- Early Tertiary muscovite granite stock. Tungsten occurs as high grade scheelite in quartz veins, veinlets, and greisen stockworks in these historic mines in the northwest part of the Yuma King property.

Historic channel sampling of the tungsten prospects are reported in a 2011 NI43-101 Report prepared for Rare Green Inc. by SRK Consulting US Inc. (Rasmussen, J.C and Hoag, C., 2011) and indicate elevated to high grade tungsten in 1 metre thick quartz veins along with elevated gold, silver, copper, molybdenum, zinc, and bismuth. Significant assays at the Three Musketeers prospect include 1.85% tungsten over 5 feet from a surface channel sample and 15.2% tungsten over 0.67 feet from an underground channel sample.

Yellowbird Graphite-Graphene Prospect

In 2011, VANE Minerals completed drillhole AZ11-02 to test a strong EM geophysical target and encountered a thick graphite bearing stratigraphic zone. Initial sampling for geochemistry and Raman spectrometry work completed on the graphite bearing interval in early 2015 confirmed the presence of graphite and established a significant graphene component was present, and in many cases the dominant component relative to graphite.

In 2016, the graphene discovery was followed up by Cash Capital with an approximately 4,000 foot drill program in 4 core drill holes to test the extent of the graphite-graphene bearing slates. Drilling, geophysics, additional lab geochemical assays, mineralogic studies, and reconnaissance field sampling have helped establish the extent of the known graphite-graphene bearing shales.
