      First 1,000 Carats Produced from Underground Trial Mining at Kono
      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 a progress update on the Kono kimberlite diamond
project in Sierra Leone.  The Kono project is a Joint Venture between
Stellar Diamonds Ltd ("Stellar") (49%) and Petra Diamonds Limited
("Petra") (51%). Mano River is a 63.2% shareholder in Stellar. 

Kono Project Highlights:

..  1,049 carats (12,132 diamonds) recovered from trial mining to end
   May 2008

..  First commercial diamond tender, and project revenues, scheduled for
   August 2008

..  Pol-K shaft in-situ kimberlite grade increased to 66 carats per
   hundred tonnes ("cpht") and Bardu shaft in-situ grade established at
   75cpht

..  Stope trial mining from Pol-K shaft due to commence in August

..  3,167 line km E-M geophysical survey completed, processing and
   target selection ongoing

Karl Smithson, CEO of Stellar Diamonds commented:

"The production of the first 1,000 carats from underground trial mining
is a significant milestone in our Joint Venture with Petra Diamonds.
We continue to be encouraged by the kimberlite grades and observed
quality of diamonds being produced.  We are moving to a position at the
Pol-K shaft where we expect to significantly increase the monthly
tonnage and diamond production. Through the planned tenders of diamonds
in August and October, and regular diamond sales in the coming months,
we expect to be able to offset project expenditure from revenues.
We take this opportunity to congratulate Petra Diamonds, our partners
and operators of the Kono project, for their continued diligent
management and excellent progress made to date."

Overview

The exploration and trial mining operations at Kono project are
progressing well and continue to deliver encouraging results.  Two
shafts are being developed, Pol-K and Bardu, and processing of
exploration and development material to date has yielded 12,132
diamonds weighing a total of 1,049 carats.

The first commercial tender of diamonds from the Kono project is
planned for August in Johannesburg, through existing Petra marketing
channels.  This is likely to comprise approximately 800 carats of
diamonds from the Pol-K shaft and will give an indication of the likely
minimum value to be realised from this kimberlite shaft.  A second,
larger tender, comprising diamonds produced from the first Pol-K stope,
is being scheduled for October.

As diamond production from the trial mining stopes increases over the
coming months, revenues from diamond sales are expected to generate
regular cash flow to offset against development expenditure.

Pol-K Shaft

Development at the Pol-K shaft is continuing at the 64.5m level, with
preparations underway for the commencement of test stope mining.
Stoping is expected to commence by August and will result in increased
ore extraction on which to assess, with more confidence, the diamond
grade and value, as well as likely mining operating costs.  The current
grade at Pol-K is 66cpht and some 668.35 carats have been produced from
this kimberlite.

Bardu Shaft

At the Bardu shaft, which is currently at a depth of 50m, a break out
from the shaft has begun and exploration development along fissure
strike has commenced.  Some 244 carats of diamond have been produced at
an average grade of 75cpht.  Shaft sinking will continue to the 64.5m
level (as at Pol-K) at which point, subject to ground conditions,
stoping operations will commence.

E-M Geophysical Survey

Due to the considerable exploration potential at Kono, a 3,167 line km
airborne electromagnetic geophysical survey has been completed by Fugro
Airborne Surveys, the objective being the discovery of kimberlite pipes
and blows. Processing of the data from the survey is expected to be
complete by August, when target identification and follow-up of
selected anomalies will commence.

Other News:
Tongo Project

Mini-bulk sampling of four kimberlite dykes has commenced at the 100%
owned Tongo project in Sierra Leone.  Previous diamond testing by
Stellar and independent analysis of these results estimated diamond
grades of between 100cpht and 500cpht for these kimberlites.
Extensions of some of these same kimberlites in an adjacent licence
were recently bulk sampled by Koidu Holdings, who reported grades of
between 196cpht and 288cpht from a 1,000 tonne sample.  The historical
diamond value for the Tongo dykes is estimated to be over US$175 per
carat, which further supports Stellar's belief that these high grade
dykes could have economic potential.
The objective of Stellar's current mini-bulk sampling programme is to
collect and process approximately 400 tonnes of kimberlite in order to
determine with more confidence the diamond grade and value from the
kimberlites within Stellar's licence area.

North DRC Project

The first phase sampling programme has been completed in the 1,308km2
Remec joint venture area.  Some 117 samples have been collected and
shipped to Stellar's diamond laboratory in Monrovia, Liberia.  Initial
results show an abundance of kimberlitic indicator minerals in some
samples, which is suggestive of the presence of as yet undiscovered
kimberlites in the licence area.  An appropriate follow up programme
will be implemented once all results are available and interpreted.
Stellar has the right to earn a 75% interest in the joint venture
through funding to the bankable feasibility stage. 

IPO Update

The Board of Stellar has decided to push back the planned IPO to Q4-08
on the basis of prevailing market conditions.  Additionally, the Board
also felt that Stellar would be in a stronger position to complete its
IPO once the first diamond tenders have been completed. By this time
Stellar expects to have realised its first revenues, adding value to
the Company ahead of the planned listing.  The Chairman of Stellar,
Lord Daresbury, has written to all Stellar shareholders in respect of
the above, as well as a proposed interim private placement of up to �2
million to be offered in July 2008.
