Constantine Intersects 21.7 Meters of 2.4% Copper and 9.1% Zinc in Step-out Drilling at the Palmer VMS Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug. 12, 2013) - Constantine Metal Resources Ltd. (TSX VENTURE:CEM) ("Constantine" or the "Company") is pleased to report results for the first four holes of a 4000 meter drill program on its Palmer VMS Project, Alaska ("Palmer" or "Project"). The drill program is part of a US $3,000,000 budget for 2013 funded by Dowa Metals & Mining Co., Ltd. of Japan ("Dowa"). Drilling is focused on expanding the South Wall and RW Zones, which host a National Instrument 43-101 compliant 4.75 million tonne inferred resource grading 1.84% copper, 4.57% zinc, 0.28 g/t gold and 29 g/t silver*. Mineralized intersections are reported for the first four holes in the table below, and represent 35 to 100 meter step-outs.

**Drill intercepts reported as core lengths are estimated to be 85-100% true width, except for CMR13-43 which is estimated to be 50 to 60% true width. Averages are weighted for length and density.

Drill holes were designed to expand and test the outer edges of the existing resource. Drill holes CMR13-43, 45 and 46 successfully expanded the outer limits of South Wall mineralization (see Figure 1) and hole CMR13-44 confirmed mineralization between the RW East and West Zones (see Figure 2).

Hole CMR13-43 intersected strong chalcopyrite stringer style mineralization and represents an approximately 35 meter down-dip step-out on Zone I. This hole was drilled on an oblique angle and stayed in footwall mineralization and alteration and did not penetrate the main massive sulphide bearing horizon. Hole CMR13-45 is a 65 meter up-dip step-out on South Wall Zone I and intersected a thick zone of massive sulphides. Hole CMR13-46 intersected South Wall Zone II massive sulphide mineralization approximately 50 meters west and 50 meters up dip of previous drilling. This intersection significantly expands an area of thick Zone II mineralization, and opens the potential to add additional tons between the base of Zone I and the currently defined top of Zone II. Based on a revised geological model, South Wall Zone II is interpreted to represent the faulted offset of South Wall Zone 1.
