ABSTRACT:Vancouver, BC – Constantine Metal Resources Ltd. (TSX Venture – CEM) ("Constantine" or the "Company") is pleased to announce an updated mineral resource estimate for the Palmer CopperZinc-Gold-Silver deposit, located in a very accessible area of coastal Southeast Alaska. A separate maiden resource for the nearby AG Zone discovery has been deferred until later this year to include recent 2018 drill results that have significantly expanded the extent of this new area of mineralization first identified in 2017. Garfield MacVeigh, President and CEO of the Company states: “We are very pleased to report that this latest update significantly expands and enhances the resource base at the Palmer Project. There is excellent opportunity to continue to expand the current resource, to add to the resource base with the planned maiden resource estimate for the AG Zone, and to make additional deposit discoveries. We are excited to incorporate these positive developments in the Preliminary Economic Assessment, establishing the path forward for this important high-grade base metal asset.” Resource Model The mineral resource estimate prepared by James N. Gray of Advantage Geoservices Ltd. is reported in accordance with Canadian Securities Administrators' NI 43-101 and conforms to the Canadian Institute of Mining "Estimation of Mineral Resources and Mineral Reserves Best Practices" guidelines. The resource incorporates all exploration drilling in the Palmer Deposit area completed to the end of 2017. One hundred and eight exploration diamond drill holes for 44,868 meters and geological surface mapping were used to generate the geological and structural model for the South Wall and RW zones. Sixty of the holes intersect the interpreted mineralized solids. Outlier assays were capped and all assays within the mineralized zones composited to 1.5-meter lengths. Metal grades were estimated using inverse distance cubed interpolation into a 3D block model with block dimensions of 6 x 6 x 6 meters. Density was estimated by inverse distance squared interpolation, with unique density values determined by conventional analytical methods for all assay samples. Three dimensional geologic solids were constructed by Darwin Green, Vice President of Exploration and reviewed by QP Ian Cunningham-Dunlop, and, in general, were limited to material grading > 0.5% Cu or > 2% Zn that could be demonstrated to be correlative with definable stratabound zones. As a general rule, solids were extended no more than 50 meters updip, down-dip and along strike from a drill hole except where geology supports extension in the plunge direction of mineralization.
