Southern Rio Resources Ltd.: New Gold Discovery on Davidson Property

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 3, 2005) - Southern Rio Resources Ltd. (the "Company") (TSX VENTURE:SNZ) is pleased to announce a significant new gold discovery on the recently acquired Davidson Property in central British Columbia.

Hole DAV-05-02 returned the following results:

Depth (m) Intercept (m) Gold (g/t) Silver (g/t)
136.0 - 150.0 14.0 metres 4.94 g/t Au 17.1 g/t Ag

within a larger mineralized zone of:

Depth (m) Intercept (m) Gold (g/t) Silver (g/t)
96.0 - 160.0 64.0 metres 1.80 g/t Au 6.5 g/t Ag

The hole was part of an initial five-hole (938.7 metres) drill program carried out in late September-October which tested a number of geophysical and geochemical targets for epithermal gold and silver mineralization on the property. Partial results have been received from the first two holes. Additional assay results, including those from DAV-05-02 below 160 metres depth, and the three later holes will be reported on receipt.

Hole DAV-05-02 was targeted on a coincident NW-SE trending gold-in-soil geochemical anomaly and geophysical conductor. The host rocks are strongly altered felsic volcanics. The 14 metre intersection is comprised of seven samples, each two metres in length; individual values range from a high of 9.81 g/t Au to a low of 2.67 g/t Au. The true width of the intersection is currently unknown. The primary assays were performed by Eco Tech Laboratory in Kamloops, check assays will be submitted to Acme Analytical Laboratories in Vancouver.

Hole DAV-05-02 is located approximately 300 metres northwest of the closest previous drill hole, DAV-92-35, which was drilled by Granges Inc. in 1992. Hole 92-35 returned 4.91 g/t Au and 1.9 g/t Ag over 4.3 metres, from 167.0 to 171.3 m (end of hole) within a wider intercept grading 2.48 g/t Au and 2.3 g/t Ag over 10.3 metres from 161.0 to 171.3 m depth.

The Davidson Property, is 100% owned by the Company and located approximately 110 kilometres southwest of Vanderhoof in central British Columbia, and approximately 20 km northeast of the Company's 3Ts project. The recent drill program was the first drill activity on the property since 1994.

The Company is very pleased with this significant new discovery in a previously untested area of the property. Given the location and size of the mineralized intercept, the Company will undertake an immediate compilation and reinterpretation of the previous geochemical and geophysical data, followed by additional drilling.

The Davidson field program is under the supervision of David Pawliuk, P.Geo. and Robert Weicker, P.Geo., both of whom are qualified persons as defined by National Instrument 43-101.
