Exploration Adit at Radius's Tambor Gold Project Intersects
Quartz Vein with Visible Gold
======================================================================

Vancouver, Canada: Simon Ridgway, the President of Radius Gold
("Radius" TSX-V: RDU), is pleased to announce that the exploration adit
on the Guapinol Zone at the Tambor gold project in Guatemala has
intersected the target vein as planned 202.1m into the hill side. The
vein has a sugary texture with locally abundant native gold and
1.0-1.5% arsenopyrite as disseminations and veinlets.

The width of the vein exposure in the tunnel is 3.2m, with a dip of 75�
for a true width of 3.09m. Diamond drill hole PDD-03-033, first
reported in Radius's news release dated August 13th, 2003, which
returned 80.5g/t Au over 5.3m from a quartz vein, is clearly exposed in
the side wall of the tunnel. Quartz veins up to 15cm thick occur for
approximately 4m into the footwall of the vein. The tunnel will be
extended to pass this zone, and additional mapping and sampling of the
vein are planned.

One of the principle objectives of the exploration adit is to allow a
better understanding of the structural controls of the mineralization
at Guapinol. The tunnel was designed to cut the vein approximately
perpendicular to its strike. The vein occurs in phyllites, and in the
tunnel it is clearly evident that it crosscuts the foliation at about a
45� angle. Previous drilling by Goldfields suggests a southeast plunge
to the vein.

The vein has been sampled (results pending) and vein material collected
during development is being stockpiled on surface from which a bulk
sample will be prepared for metallurgical testing. Several photos
showing samples of the quartz vein material with visible gold have been
posted on the web site, and an updated map and cross section of the
tunnel will be posted shortly at www.radiusgold.com .

The Tambor properties host an orogenic lode gold belt, discovered by
Radius in 2000 and explored by Gold Fields under joint venture until
2004. Gold Fields drill tested the Guapinol, La Laguna, Poza del
Coyote and Cliff zones and outlined a 43-101 compliant resource of
216,000 ounces of gold in inferred resources (2.55 million tonnes @
2.64 g/t Au) and 57,800 ounces in indicated resources (456,000 tonnes @
3.94 g/t Au) prepared by Chlumsky, Armbrust and Meyer LLC (CAM) of
Lakewood Colorado (see Radius news release dated December 10th, 2003).
The new structural information may be used to further evaluate the
known mineralized zones and targets within the Tambor belt. Targets
for further exploration include two parallel east-west trending +50ppb
gold-in-soil anomalies over a 7km trend between Laguna North and
Guapinol South.
