Southern Rio Resources Ltd.: Tommy Vein Intersection
Highlights Tsacha Program

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 14, 2005) - Southern
Rio Resources Ltd. (the "Company") (TSX VENTURE:SNZ) is pleased to
report further results from the winter drilling program on the 3Ts
project southwest of Vanderhoof in central BC. Assay results have now
been received for the twelve holes drilled on the optioned Tsacha
property. The Tsacha drilling was planned to further test the Tommy
Vein, where previous work has outlined an inferred mineral resource of
552,500 tonnes grading 6.82 g/t gold and 60.9 g/t silver, as well as a
number of conceptual targets elsewhere on the property.

The highlight of the program was hole TS-05-108, drilled to test the
central portion of the vein system immediately below a 100 metre thick
intrusive sill. Limited previous drilling in this area had returned
inconclusive results. Hole TS-05-108 intersected 14.37 metres of
quartz-carbonate vein starting from 220.56 metres depth. An 8.86 metre
interval from 220.56 to 229.42 metres (estimated true width 6.0 metres)
grades 10.89 g/t gold and 60.2 g/t silver, including a higher grade
interval of 2.56 metres grading 23.1 g/t gold and 153.2 g/t silver. Hole
TS-05-108 also intersected a 2.33 metre interval of the Larry Vein above
the sill from 40.27 to 42.60 metres. A 1.0 metre interval of the Larry
Vein from 40.27 metres (estimated true width 0.7 metres) grades 19.7 g/t
gold and 150.0 g/t silver.

The Tommy Vein intersection demonstrates that the vein structure is
strongly developed in this area and remains open, particularly along
strike to the north from the TS-05-108 intersection. A cross section
( and a long section
( showing the position of the
TS-05-108 intersection in relation to other drill holes on the Tommy
Vein is posted on the Company's website.

At the south end of the Tommy Vein, step-out drilling from previous
drill hole TS-04-90 (which returned an intersection of 9.0 metres
grading 8.83 g/t gold and 62.6 g/t silver) encountered narrower widths
and lower grade values.

The results from TS-05-108 have opened up a new segment of the Tommy
Vein system as being prospective for ore grade and width intervals. The
geology in this area is complex, with both faulting and irregularities
in the sill contact being possible explanations for the lack of success
in the previous drilling. Drilling on the property ceased last week due
to the imminent arrival of spring break-up. The Company's technical team
is currently reviewing all data from the program before making
recommendations for further work.

The 3Ts field program is under the supervision of David Pawliuk, P.Geo.,
who is a Qualified Person as defined by NI 43-101. The primary assay
laboratory used is Eco Tech Laboratory in Kamloops, with check assays
being performed by Acme Analytical Laboratories in Vancouver.
