Update on Nicaragua Exploration Programs
======================================================================

Simon Ridgway, President of Radius Gold Inc. (TSX-V: RDU) is pleased to
provide further results from its exploration projects located in
Nicaragua.

Trebol trenching returns 4.9 g/t Gold over 35.2 meters, including 8.35
g/t Gold over 17.6 meters

Mapping, prospecting and trenching have further expanded the broad zone
of alteration and mineralization at its Trebol property to over 5.6 km
in strike length, comprising a series of low-lying, silicified volcanic
ridges. A total of 13 trenches have now been excavated and sampled.

Trenching to date has highlighted two areas, some 2.6 km apart, in the
vicinity of trenches TRSD-02, 03 & 04) and TRSD-05 & 06 respectively.
Surface rock exposure is limited due to soil and vegetation cover, and
trench locations were based on results from sampling of available
outcrops. Results from initial sampling at trenches TRSD-03 and TRSD-04
were previously reported by Radius and were extended to 34.0 and 35.23
m respectively. An updated map showing trench locations can be found on
the Radius website at www.radiusgold.com.

(i) reported previously - see press release 29 May 2007

Trench TRSD-03 is located 150m from trench TRSD-02. Trench TRSD-04 is
located 700m from Trench TRSD-03. Highest gold grades are associated
with massive sugary quartz veins, breccias and stockworks, with
abundant iron oxides and pyrite. Lower gold grades (<2 g/t) are hosted
by intervals of andesitic volcanics with weaker
silicification/stockworks, chalcedonic quartz veining and strong
clay-sericite alteration.

The mineralization appears to be controlled by several structural
trends, and broader areas of alteration and mineralization appear to
coincide with several structural "nodes" where different trends
converge. Additionally, prospecting and sampling has shown anomalous
gold values in rocks over 1km west and east of the main trend, with up
to 6 g/t gold reported and associated with similar low-lying ridges and
topographic highs.

All trenches started and ended in mineralized and/or altered rock with
anomalous gold values. The full width of the mineralized system at
Trebol remains unconstrained due to soil and vegetation cover.

The sampling reported above was undertaken before the region was
affected by Hurricane Felix, (see press release dated 12 Sept 2007.)
The Category 5 storm caused widespread damage in the region. Work at
Trebol has been effectively suspended until crews can safely return to
the area.

Radius begins work at La Flor

The La Flor property is located some 10 km immediately south of the
Trebol, and is a new acquisition by the Company (see press release 12
Sept 2007). Trenching and sampling has commenced at Linda Ventura
located within the 15,605 hectare La Flor concession. The main Linda
Ventura vein has been traced for at least 1.1 km, and several new veins
have been located. Previous sampling of the main workings at Linda
Ventura gave trace to 8.5 g/t Au, with visible gold in many samples. A
total of 21 trenches have been excavated and sampled, and 9 line km of
soil samples have been taken, with results pending. Regional mapping
and sampling have also commenced within the remainder of the La Flor
concession, where several other low sulphidation vein systems are
known.

Radius acquires the Estrella de Oro Gold Project

Title has recently been granted to a new epithermal gold property in
north-central Nicaragua. The Estrella de Oro property consists of
46,220 hectares and is located 17 km west of the town of Siuna, within
Nicaragua's "Golden Triangle". An all-weather dirt road transects the
central part of the property.

In the Cerro Estrella area, old mine workings are present along two
parallel, north-easterly trending structural zones and comprise quartz
veins and breccias hosted within crystal and lithic tuffs. The most
southerly vein contains visible gold and is approximately 12m in width
and exposed over some 400m in old trenches and pits. Rock channel
samples of vein material taken by Radius assayed from trace to 21.5 g/t
Au over 2m and 22.4 g/t Au over 1m. The zone remains open to the
northeast and southwest.

Future work by Radius will consist of stream sediment sampling,
mapping, trenching and channel sampling to define the extent of the
known mineralization and locate additional target areas for follow-up
and drilling.

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.
