DRILLING AT PALMER PROJECT TO START UP MID-JULY

Constantine Metal Resources Ltd. plans to start up diamond drilling on its Palmer massive sulphide Palmer project around July 15, 2007. The drill program is planned to initially test low-elevation targets at the Cap and Southwall. Prior drilling at the Cap prospect encountered the following drill intercepts: 23.2 metres (76.1 feet) in Cap-01 of 134 parts per million silver (3.91 ounces per tonne), 0.24 per cent zinc, 0.16 per cent lead and 90.6 metres (297.2 feet) in RMC98-01 of 31 ppm silver (0.90 ounce per tonne), 8.57 per cent barium that includes 10.9 metres (35.8 feet) of 62 ppm silver (1.81 ounces per tonne), 0.19 ppm gold, 0.21 per cent zinc and 16.13 per cent barium. Only one hole (RMC98-02) has partially tested the Southwall target that ended in mineralization assaying 3.47 per cent zinc over 6.04 metres (19.8 feet).

The drill will then follow up on the RW zone discovery at Glacier Creek that includes 5.12 metres grading 10.86 per cent Zn, 0.13 per cent Pb, 0.23 per cent Cu, 0.134 gram per tonne Au and 44.4 g/t Ag (1.30 ounces per tonne) in drill hole CMR06-01 and 19.5 per cent Zn over 0.79 metre in CMR06-02. Please visit the Constantine website for additional information.

The scheduled closing of the Munroe-Croesus acquisition is deferred to July 30, 2007, to allow the parties time to complete closing arrangements.
