Mano River Resources Inc.: Initial Resource Exceeds 1 Billion Tonnes of Iron Ore With Further Potential at Putu

Mano River Resources Inc. ("Mano" or the "Company") (TSX VENTURE:MNO)(AIM:MANA)
the TSX Venture Exchange ("TSX-V") and AIM listed exploration to production
company focused on gold, iron ore and diamonds in West Africa is pleased to
announce an initial Independent Mineral Resource estimate of 1.08 billion tonnes
of iron ore at the Company's 38.5% owned Putu Range iron ore project ("Putu") in
Liberia.


Highlights:

- Independent Mineral Resource of 1.08 billion tonnes of iron ore at 37.6% total
iron (Fe) at Putu in Liberia


- Mineral Resource covers only a 2.6km section of 12km ridge

- Potential for the Putu resource to grow as exploration programme advances

- Best drill results to date of 91m at 61.3% Fe oxidised BIF haematite and 232m
at 40.8% Fe magnetite


- 61.5% project partner Severstal Resources investing US$30m and working with
the Company towards a Pre-Feasibility Study during 2010


Luis da Silva, President & CEO of Mano commented:

"We are delighted to announce this initial 1 billion tonne Mineral Resource
estimate, especially as the resource covers less than one quarter of the 12km
strike length of the Putu iron ore project in Liberia. Although early in the
exploration programme this is encouraging in order to reach the sort of scale
that will enable such a large infrastructure project to become economically
viable. The discussions with the Government of Liberia for the 25 year mining
licence are progressing."


Mineral Resource Estimate

In July 2009 SRK Consulting (UK) Ltd ("SRK") was engaged, as part of the AAR
transaction, to produce an Independent Mineral Resource Estimate for the Putu
Iron Ore Project. The Mineral Resource estimate has been prepared under the
guidelines of National Instrument 43-101 and accompanying documents 43-101.F1
and 43-101.CP ("NI43-101") and is based on previously announced exploration and
more recent drilling results.


The Mineral Resource estimate for the 2.6km section of the 12km ridge drill
tested to date provided an initial Inferred Mineral Resource of 1,077 million
tonnes at a grade of (37.6%) total of Banded Iron Formation (BIF)
mineralisation. This is based on the 11 recent diamond drill holes, including
the latest assays for holes PDD009-PDD011. The Joint Venture company of
Severstal Liberia Iron Ore, is continuing its exploration and is shortly to
restart a CRIRSCO-compliant resource definition diamond drilling programme, as
previously announced.


The assay data was composited to 5 metres and used in statistical and
geostatistical (Variography) studies that enabled Ordinary Kriging (OK) to be
applied as the main grade interpolation method.


The site visit and inspection of sample preparation facilities has been
undertaken by Howard Baker, Principal Mining Geologist with SRK, (Qualified
Person as designated under NI43-101) during July 2009.


SRK has reported the Mineral Resource split into the following material types:

- Oxidised BIF (CAP) material,

- Haematite BIF (HBIF), and

- Magnetite BIF (MBIF).

This Mineral Resource Statement is presented in Table 1. The statement has been
classified in accordance with the Guidelines of National Instrument 43-101 and
accompanying documents 43-101.F1 and 43-101.CP. It has an effective date of 20
July 2009 and the full report will be available on Sedar (www.sedar.com) and the
Company's website (www.manoriver.com) the week commencing 10 August 2009.

prospect for economic extraction.


In addition to the Inferred Mineral Resource as quoted above in Table 1, beneath
the 300RL, and within the geological model, there is some 364 Mt of magnetite
BIF.


Drilling Results

Geochemical analyses have now been received from OMAC for the last of the core
samples from the 2008 Putu drilling campaign. Summary results for all 11 holes
drilled last year are presented in Table 2. PIOM is in the process of engaging
an analytical services contractor to complete Davis Tube Recovery (DTR) testing
on all of the 2008 drilling samples, which will provide invaluable metallurgical
information in the early stages of the PFS.

Quality Control and Sample Preparation

Mano has a rigorous Quality Control Program (QCP) inserting a minimum 5%
standards, blanks and duplicates into the sample stream. The Company employs
independently owned and managed OMAC Laboratories for all its assay
requirements, including the preparation of pulps to 90% -100 micron at their
in-country preparation facilities in Liberia, followed by XRF at their main
laboratory in Loughrea, Ireland.


OMAC is accredited to ISO 17025 by INAB (Irish National Accreditation Board)
which is a member of ILAC (International Laboratory Accreditation Cooperation),
and is a signatory to the ILAC Mutual Recognition Arrangement. OMAC operates an
internal QA/QC check assay programme using in-house standards, reagent blanks
and duplicates.


Overview of the Putu Iron Ore Project

The Putu Iron Ore project is located in the centre of a 425 sq km exploration
licence in Grand Gedeh County of eastern Liberia, approximately 100km north east
from a potential deep water port of Greenville and 200km south east of the Mt.
Nimba iron ore deposit.


The Putu project consists of two prominent ridges that strike northeast
southwest, namely, Mt Jideh (with its extension Mt Montroh) and Mt. Ghi.
Exploration to date has focussed on Mt Jideh, which comprises a high-grade
outcropping magnetite/hematite mineralised zone that has undergone various
stages of weathering. Mt Jideh has a strike length of approximately 12km based
on mapping, surface sampling and airborne magnetic data.


The lower priority target called Mt Ghi runs parallel to Mt Jideh and though
massive does not have a magnetic anomaly or significant outcrop. A programme of
30 reconnaissance grab samples at Mt Ghi had returned an average grade of 39.3%
Fe. The grade is believed to be associated with a deep tropical weathering
profile. Mt Ghi has been excluded from any Mineral Resource estimation.


Severstal Joint Venture

its wholly owned subsidiary, Lybica Holdings B.V. The Company signed an
agreement on 22 May 2008 and subsequently completed the transaction with
Severstal on the 10 December 2008. The deal provides for US$15m cash being
injected into the joint venture company, now renamed Severstal Liberia Iron Ore
Ltd, as well as an additional US$15m debt facility. This US$30m will provide for
the specific advancement towards a definitive feasibility study.


Severstal Resources is the mining division of OAO Severstal (www.severstal.com)
and one of the biggest mining companies in Russia. Severstal Resources manages
all Severstal's mining assets: two iron ore mining complexes and a coking coal
complex in northwest Russia, one coking coal complex in USA (PBS Coal), a
ferroniobium extraction complex in West Russia and an exploration project,
Severstal Liberia Iron Ore in West Africa. Severstal Resources also manages a
number of gold mining assets in Russia, Kazakhstan and Burkina Faso as well as
several gold exploration fields in these regions. In 2008 EBITDA was $859
million. OAO Severstal is an international metals and mining company with a
listing on the Russian Trading System, Moscow Interbank Currency Exchange and
the London Stock Exchange. Its enterprises are located in Russia, Ukraine,
Kazakhstan, United Kingdom, France, Italy, United States and Africa. In 2008,
Severstal produced 19.2 million tonnes of steel. Revenues were $22.4 billion and
EBITDA was $5.4 billion. EPS was $2.2.
