Encouraging Diamond Results from Tongo Project in Sierra Leone
======================================================================

Mano River Resources Inc. ("Mano" or "the Company"), the TSX-V and
AIM-listed exploration and development company focussed on West Africa
is pleased to announce encouraging initial diamond recoveries from the
Tongo kimberlite project in eastern Sierra Leone. The Tongo project is
a Joint Venture between Mano's 68.5% owned subsidiary company, Stellar
Diamonds Limited ("Stellar") and BHP Billiton. BHP Billiton can earn
up to a 51% interest in the Tongo project under the current spending
plan of $3.4million, with a further option to earn up to 70%.

Highlights of the initial recoveries are:

.. 1,894 diamonds, totalling 2.05 carats, recovered from six 200 kg
(dry weight) samples, including

.. 49 diamonds over 0.85mm recovered, totalling 1.43 carats

.. 72 diamonds, totalling 2.85 carats, recovered from 23 surface grab
samples

Stellar's CEO, Karl Smithson, commented:

"We are extremely pleased with these results and consider the
significant number of diamonds recovered to be a promising indicator of
potential grade. Additionally, the presence of diamonds in the plus
0.85mm size fraction from these small samples is particularly
encouraging. With our partners, BHP Billiton, we are now undertaking a
1,200m drilling programme aimed at locating any potential kimberlite
pipes or blows associated with the dykes and look forward to providing
an update in due course."

Four kimberlite dykes have been mapped and trenched at various points
along strike by Stellar on the 33km2 Tongo project, which is a retained
area from the original 9,700km2 Reconnaissance Exclusive Prospecting
Licence. The dykes in the licence area currently range in strike
length from 0.5km to 2km and range in width from a few centimetres up
to 1m. Tongo is located 35km south of the Kono Joint Venture between
Stellar and Petra Diamonds where underground test diamond mining is
underway.

Six 200kg (dry weight) samples were collected from the Tongo trenches
and consigned to the SGS Lakefield Research Africa laboratory ("SGS")
(non ISO compliant) in Johannesburg, South Africa for total diamond
liberation by caustic dissolution.

Some 1,894 diamonds weighing a total of 2.05 carats were recovered. The
full results are shown in Table 1. All six samples yielded a
significant number of diamonds, many in excess of 0.85mm (i.e. 'DTC
sieve size 1'). The highest number of diamonds recovered from a single
sample was 756 diamonds (totalling 0.317-carats) from Dyke 3 (sample
JV-2527). However, the most carats from a single sample (0.534-carats)
were recovered from Dyke 1 (sample JV-2525). The largest diamond
recovered was a white octahedral stone weighing 0.31-carats (Dyke 1
sample JV-2525). The SGS laboratory described the majority of the
diamonds as white, transparent or translucent, dodecahedrons,
octahedrons or fragments. A number of these diamonds show perfect or
near perfect preservation and exhibit octahedral form.

In addition to the six samples submitted for caustic dissolution,
Stellar also collected 23 surface grab samples from the four dykes.
These samples ranged in wet weight from 20 kg to 1,200 kg, and were
processed in-field by washing and manual concentrating to produce a
greater than 0.3 mm mesh sized concentrate. Diamonds were recovered
from the concentrates using a binocular microscope in the kimberlite
indicator mineral laboratory established by Stellar in Monrovia,
Liberia. Some 72 diamonds, weighing 2.85-carats, were recovered from
22 of the 23 samples collected and processed. The full results are
shown in Table 2.

About the laboratory procedure

At the SGS laboratory in Johannesburg, South Africa, the samples were
dried and 200kg (dry weight) of each sample was subjected to total
diamond liberation through caustic dissolution (4kg sample aliquots
boiled at 550-deg Celsius in caustic soda for 14 hours). The fusion
residues were then passed through a 90 micron sieve and the +90 micron
fractions were then dried and passed to the MSA Geoservices laboratory
for diamond picking. Diamonds that reported to the +0.075mm square
mesh sieve size were recovered, measured (X,Y,Z axes), described and
weighed. Diamonds reporting to the +0.212mm sieve size were weighed
individually, whereas diamonds reporting to the -0.212mm sieve size
were weighed together in their respective sieve class size.
