Mano River update on Putu Range iron ore project in Liberia



    TSX-V: MNO
    AIM:   MANA

    VANCOUVER, March 12 /CNW/ - Mano River Resources Inc. ("Mano" or "the
Company") the TSX-V and AIM listed exploration and development company
focussed on West Africa, provides an update on progress from its 80% owned
Putu Range iron ore project ("Putu Range") in eastern Liberia.

    
    -   Historic reports indicated a 500 Mt potential for Mt. Jide
    -   Up to 67.3% Fe from outcrop grab samples and 59.3% Fe from first 26m
        of historic adit
    -   Pre-feasibility study with 4,000m of drilling planned to commence in
        2007
    -   Deposit well situated being +/-100km from an existing port
    -   Sampling commenced on the second ridge Mt. Ghi
    -   Optimal exploration and development options under consideration
    

    Putu Range consists of a series of north-south trending ridges of which
the most easterly, Mt. Jide ridge, has been the focus of work by Mano to date
and was the subject of limited past work in the 1950s/60s. Putu Range is
centred within a three year exclusive exploration licence for iron ore granted
to Mano River Iron Ore (Liberia) Inc ("MARIO") on May 18th, 2005, covering an
area of 425km2 in Grand Gedeh County, approximately 100km north east of the
potential deep water port of Greenville. Since September 2006, independent
consultants McLellan and Partners have supervised a sampling and site
preparation programme, in advance of a pre-feasibility study, which is
planned, subject to financing, to commence in 2007 and include up to 4,000m of
diamond drilling.
    Grab samples from a 4km section of the 12km long ridge at Mt. Jide, and
channel samples of the first 26m of a 50m long historic adit located
approximately 300m below the crest line, returned highly encouraging average
grades of 57.9% Fe and 54.2% Fe, respectively. Results from this programme are
detailed in tables 1 and 2 below.

    Mano's CEO, Dr Tom Elder, commented:

    "These sample results confirm that, whilst at an early stage, the Putu
Range iron ore project exhibits the potential scale to develop into one of
Mano's premier assets by contained value. Preparations are underway for a
Phase 1 systematic exploration programme to commence, which will include
drilling, in order to more accurately delineate the extent and style of
mineralisation and to prepare an initial independent resource estimate."

    Current programmes

    Access roads have been established and drill pad preparation is underway.
Systematic sampling is on-going along an additional 2.5km long strike section
of the main zone of Mt. Jide, within recently discovered trenches which appear
to date from the 1950s and 1960s. Channel sampling of the remaining 30m of the
historic adit will commence once rock wall stability has been secured. Further
geological mapping and a detailed topographic survey are planned to commence
in March. In parallel with these programmes, a pilot mineral processing study
will be undertaken to investigate the optimal separation method for the
quartz, which is the principal deleterious mineral, in order to upgrade the
ore. Mineralogical studies completed by Mano to date suggest that gravity
separation is the likely upgrading method.

    About African Iron Ore Group Ltd.

    MARIO is owned by African Iron Ore Group (AIOG), itself 80% owned by
Mano. Mano are considering options to take forward the development of AIOG's
Putu Range property and consider a separate listing for AIOG on London's AIM
or PLUS Market, subject to views by shareholders. Taking into account the
Liberian Government's expressed wish to fast track economic development, the
Company is also entertaining cooperation and / or joint-venture discussions
with a number of large iron ore groups.
    Finally, Mano is seeking advice with respect to valuation and taxation,
for the purpose of potentially distributing Mano's shares in AIOG to Mano
shareholders.

    About the Putu Range Iron Ore project

    The Putu Range project is centred within a three year exploration licence
awarded in May 2005 which covers an area of 425km(2) in Grand Gedeh County
Liberia. The deposit is approximately 200km south east of the 1 billion tonne
Mt. Nimba iron ore project that straddles the border with Guinea, being
developed at a reported cost of $1bn by Mittal Steel. Four other Liberian iron
ore deposits are currently being explored by BHP Billiton.
    The Mt Jide ridge of the Putu range project comprises a high-grade
magnetite/hematite mineralised zone with a strike length of approximately
12km. Putu was first explored in the 1950s and 1960s by LAMCO
(Liberian-American-Swedish Mining Company) which moved on to develop the
Yekepa, Nimba deposit (now Mittal) and the predecessor company to Bong Mining
Company, who completed a limited drilling and underground bulk sampling
programme to move on to develop the Bong deposit. Historic reports from this
period suggest that Mt. Jide ridge potentially contains in excess of 500
million tonnes of non-NI 43-101 compliant iron mineralisation with grades up
to 67% Fe. Sampling and mineralogical analysis completed by Mano indicate that
the predominant iron mineral is hematite and that the quality of the
mineralisation is high, with low phosphorous levels and a coarse grain size to
the quartz present. The project has gentle relief from the Putu Range to the
ocean and is relatively close (100km) to a potential deep water port.
    Prior to 1989 Liberia was the largest producer of Iron Ore in Africa,
exporting over 15 million tonnes annually, contributing approximately 50% to
government revenue.

    About Mano River Resources Inc ("MRRI")

    MRRI is a well established exploration and development company focused on
the Archaean terrain of the highly prospective, under-explored, West African
'Mano River Union' countries of Sierra Leone, Liberia, and Guinea. MRRI
operates three distinct divisions, which hold over 18,500km(2) under licence,
summarised as follows:

    
    Mano Gold Ltd, 100% owned by MRRI:

           1.4Moz gold resource (13.533 million tonnes of measured and
           indicated resources grading 3.18 g/t) at New Liberty Gold Project
           in Liberia, where open pit gold production of at least 84,000 oz
           pa is planned to commence in 2008, subject to financing and
           permitting.

        -  Holds a pipeline of highly attractive drilled prospects within its
           1,000km(2) Bea Mountain Licence in Liberia including Weaju

           on the Lion Kimberlite Dyke project in the Kono diamond fields of
           Sierra Leone, with underground diamond production planned to
           commence in late 2007. A processing plant is already built and
           exploration shaft sinking is ongoing.

        -  Has a joint Venture with Trans Hex Group who are earning an
           initial 50% interest in the Weasua cluster of diamondiferous
           kimberlite pipes in Liberia, where bulk sampling to determine
           diamond grades and value is currently underway.

        -  Has a 50:50 joint venture with Searchgold Resources on the
           Mandala / Bouro alluvial and kimberlite dyke project in Guinea.

        -  Holds a 15,000km2 licence in west Liberia with diamond bearing
           kimberlites and numerous high interest mineral indicator
           anomalies.

        -  Has a joint venture with BHP Billiton who are earning an initial
           51% interest in the south eastern Sierra Leone tenements. The
           joint venture has located diamond bearing extension of the high
           grade Tongo dyke field.

        -  Is earning a 78% interest in the North Bea exploration project
           from African Aura in Liberia.

    African Iron Ore Group Ltd, 80% owned by MRRI:

        -  Holds an 100% interest in the 12km long Putu Range Iron Ore
           project where historic reports from Mt Jide indicate a potential
           of 500 million tonnes (not yet in compliance with the NI 43-101
           code) and excluding any potential resources on other ridges.

        -  Holds a 3.68% minority interest in Mifergui Nimba, holder of a
           5% interest (which is free carried for the first $100M invested)
           in the BHPBilliton-managed one billion tonne Nimba iron ore
           deposit in Guinea, which straddles the Liberian border where it is
           being redeveloped by Mittal Steel.
