REGENCY MINES PLC



Exploration Update



Dated: 24th September 2007

Regency Mines plc ('the Company') the mining exploration and mineral investment
company with interests in copper and nickel in Papua New Guinea, Western
Australia, and Queensland, is progressing with exploration at the Company's
lateritic Nickel-Cobalt project at Mambare Plateau, Papua New Guinea ('Mambare
').



To date 30 auger core holes (CAA 1-30) have been drilled. These holes have been
located at 100m intervals on lines 22400, 22800 and 23200N across the previously
explored ridge west of the Arumu River. Individual holes range up to 10.3m in
depth and total 167m. Limonite laterite has been intersected in all holes. Up to
7.65 metres of limonite laterite has been intersected in individual holes.
Overlying ash is commonly less than 3m thick. 180 samples have been submitted to
an Indonesian laboratory for XRF analyses.



One auger core drill has been equipped with hydraulic feed and is currently in
use. Another auger core rig is being rebuilt and equipped with hydraulic feed
and a diamond drill bit to effect better penetration, to ensure intersection of
the complete limonite profile, which the holes drilled to date have failed to
do. The Company is sourcing an additional diamond drill rig, since only diamond
drilling will penetrate fully the harder saprolite ore underlying the limonite.



The wacker drill encountered early problems which have been addressed by
fabricating stronger wacker rods in Australia. These have now arrived in Papua
New Guinea and are currently in transit to Kokoda. It is anticipated that the
wacker drilling will recommence this week.



The Company has entered into a Research Services Agreement with the General
Research Institute for Nonferrous Metals (GRINM) of Beijing, China. This
agreement provides for a three month programme of hydrometallurgical test work
on ore from Mambare. Follow up work will be conducted on site leading to process
flow recommendations and an economic analysis.
