Exploration Update

REGENCY MINES PLC

                               Exploration Update


Dated: 18th June 2007

Regency Mines plc (the "Company") announces that a programme of drilling has
begun on the company's Mambare license in Papua New Guinea.

The programme will start on 100m centres at the Southern end of the license
along the Ukita and Namara ridges and covers areas previously explored by auger
drilling and pitting. Drilling will be closed in to 20m centres in certain
areas, and will intensify in stages, continue until a JORC resource is defined
in the immediate target area, which lies along the edge of the Mambare plateau
close to the existing Kokoda-Popondetta-Oro Bay road.

The objective is to identify a resource sufficient to justify a decision to
commence direct shipment of limonite ore.
