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

LONDON, UNITED KINGDOM--(Marketwire - Aug. 3, 2009) - 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.


  • 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 ( and the Company's website ( the week commencing 10 August 2009.

Table 1:  Putu Deposit, Initial Mineral Resource Statement

Category Material Tonnes (Mt) Fe (%) Al2O3 (%) SiO2 (%) P2O5 (%) LOI (%)
Inferred CAP 126 43.9 7.7 21.4 0.32 6.4
Inferred HBIF 283 34.3 1.8 42.3 0.17 1.7
Inferred MBIF 668 37.8 0.5 40.8 0.18 0.0

*Reported above 300 Relative Level (RL), as of 20 July 2009, at zero cut-off grade, with no optimised pit shell, which is considered to represent reasonable 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.

Overview of the Putu Iron Ore Project

ThePutu Iron Ore project is located in the centre of a 425 sq km explorationlicence in Grand Gedeh County of eastern Liberia, approximately 100km northeast from a potential deep water port of Greenville and 200km south east of theMt. Nimba iron ore deposit.

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

Thelower priority target called Mt Ghi runs parallel to Mt Jideh and thoughmassive does not have a magnetic anomaly or significant outcrop. A programme of30 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 weatheringprofile. Mt Ghi has been excluded from any Mineral Resource estimation.
