Exploration Update

Regency Mines PLC 15 September 2005 Regency Mines plc (the 'Company') Exploration Update Dated: 15 September 2005 BUNDARRA PROJECT Soil sampling and geological mapping has been completed over three prospects within the Bundarra project area; Isens, Flora Range and Mt Flora. At Isens, soil sampling was completed on 200m x 80m centres in open terrain. Results were significant; peaking at 3.1% copper with 0.9g/t gold and 10.8g/t silver. Other results include 0.5% copper with 0.36g/t gold and 2.5g/t silver. Copper and gold anomalism has been outlined over approximately 1500m of strike and remains open to the west. At surface, mineralisation is up to 30m wide and hosted by a brecciated, iron-stained quartz-feldspar porphyry. Primary sulphides are chalcopyrite and pyrite, with secondary copper carbonates of malachite and azurite. Drilling of three traverses of angled RC holes is required to test mineralisation at depth. At Flora Range, soil sampling was completed over 4km of strike on 200m x 80m centres. Copper and gold anomalism was outlined over the entire 4km of strike and remains open to the southwest. Maximum results were 2400ppm copper with 28ppb gold and 2.7g/t silver. Mineralisation is hosted by discontinuous lodes of brecciated granite intruded by veins of iron and malachite stained quartz-feldspar porphyry. Ten sets of historic workings were located within the Flora Range area, each commonly returning +2% copper from historic rockchip sampling by previous explorers. Only one working has been tested by a single RC hole that, significantly, returned 3m @ 7.2g/t gold from 36m. A ground geophysical survey (IP) and RC drilling is required to test the peak geochemical response. At Mt Flora, the immediate area of historic workings has been subject to much surface exploration in the past and, consequently, soil sampling and mapping was focused on potential northern and southern strike extensions to mineralisation. Sampling returned a peak of 254ppm copper and 7ppb gold. Results confirmed mineralisation continues northwest of the historic workings for some 2500m, and also southeast for a further 1800m. However, mineralisation is of a more subtle nature than that encountered at Isens and Flora Range. This suggests a large, low-grade disseminated style of mineralisation for Mt Flora. Step out RC or Diamond drilling of the Mt Flora mineralisation is required. Airborne Geophysical Data During August, magnetic and radiometric data from a detailed airborne survey were processed and imaged. Total count (K, Th, U) radiometric data illustrates the strong alteration of the Permian sedimentary rocks in contact with the margin of the Bundarra intrusion, and highlights the potential for economic accumulations of uranium. Subsequent imaging of the airborne uranium data revealed several discrete anomalies within the project area. These are scheduled for ground follow-up during the current field season. The directors consider the results to date of the sampling and mapping program at Bundarra to be encouraging and to justify moving to the next stage of exploration. The results in the Isens area mean that this will be a focus of further exploration effort, including drilling. The Flora Range results will also be followed up by further exploration, including drilling. Continued mapping and sampling of areas around the edge of the Bundarra intrusion will be undertaken to test hitherto unexplored areas. The objective remains to identify and delineate high grade copper zones as well as potential low grade bulk tonnage targets. Several areas have uranium anomalies identified from the radiometrics and will be tested by field work.
