Radius's Tambor Exploration Adit Returns Additional Intercept of
65.6g/t Gold Over 4.45m
======================================================================

Vancouver, Canada: Simon Ridgway, the President of Radius Gold Inc.
(TSX-V: RDU), is pleased to announce that the exploration tunnel and
four cross-cuts have been completed at the Guapinol vein at the Tambor
gold project in Guatemala. Sampling of the crosscuts has been completed
and results received for all but the second cross cut to the East
(CE-2) - these results are pending.

Crosscut CE-1, parallel to and 12.75m to the east of the main adit,
intercepted a vein zone with 3 veins, where it assayed:

* 65.64 g/t Au over 4.45m from the vein zone on the East tunnel
wall

* 25.78 g/t Au over 4.38m from the vein zone on the West tunnel
wall

Crosscut CE-2, parallel to the adit and 22.75m to the east, intercepted
on the west wall a 2.69m wide vertical quartz vein, where trace visible
gold was observed. The vein is cut off at an acute angle by a 0.3 to
0.4m wide fault gouge zone with fragments of quartz vein and phyllites,
with a 0.3m wide vein fault-wedge exposed on the east wall. Results are
pending.

Crosscut CW-2, parallel to the adit and 24.8m to the west of the main
adit, intercepted a thin vein, where it assayed

* 0.54 g/t Au over 0.8m from the vein on the East tunnel wall

* 0.50 g/t Au over 1.5m from the vein on the West tunnel wall (from
2 veins 0.2m and 0.4m wide)

These results and those reported previously from Crosscut CW-1 (see
press release 6 September 2007) continue to support the interpreted
easterly plunge for the quartz vein, with its base intercepted in
crosscut CW-2.

The work done demonstrates the along strike continuity of the structure
and the persistence of the high gold-grades in the quartz bodies. The
interpreted easterly plunge of the vein would therefore suggest that
the mineralization remains open to the west (vertically above CW-2 and
partly defined by 2003 drilling) and to the east.

A bulk sample from the vein in the adit has been collected and will be
sent for metallurgical testing to determine the amenability of the ore
for gold recovery.

An updated map and cross section of the tunnel has been posted at

Background

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 10, 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.

Assay Protocol & Qualified Person

All sample preparation and analyses were conducted by CAS Laboratories
in Tegucigalpa, Honduras. Samples were analyzed for Au, using a 30 gram
pulp with Fire Assay, AA finish. Check assays are undertaken by Acme
Laboratories in Vancouver.

The scientific and technical information in this release was prepared
under the supervision of Mr. David Cass, Radius's Vice-President of
Exploration, who is a member of the Association of Professional
Engineers and Geoscientists of British Columbia, and a "Qualified
Person" in accordance with National Instrument 43- 101.
