Marketwired Canada
Mano River Resources Inc. (TSX VENTURE:MNO)(AIM:MANA)("Mano" or "the Company")
the TSX-V and AIM-listed exploration and development company focussed on gold,
diamonds and iron ore in West Africa, announces:
- Highly encouraging results from deep diamond drilling at its New
Liberty Gold Project
- Assay results from the first eight holes received
- All eight holes intersected ultramafic schist units, host to the gold
mineralisation
- Two of the six holes drilled to the minus 200m level returned some of
the best intersections ever achieved at New Liberty, i.e.:
K-115 23m grading 4.95 g/t gold (including 12m at 9.12g/t)
K-116 31m grading 3.59 g/t gold (including 17m at 7.03 g/t)
- Both deep holes drilled to the minus 500m level confirmed the presence
of the gold zone, the better intersection being:
K-120 19m grading 1.18 g/t gold (including 3m at 6.21 g/t)
The New Liberty Gold project lies within a 1,000km2 combined exploration and
mining licence termed a Mineral Development Agreement ('MDA') in Grand Cape
Mount County, western Liberia, 100km north west of Monrovia. It is held 100% by
Mano, subject to a 10% free carried interest and a 3% production royalty, both
held by the Government of Liberia.
2008 Drilling Programme
Subsequent to the completion of the New Liberty Feasibility Study in early 2007,
a review concluded that there was a need to define, from the outset, an
operation with a longer life than that envisaged in the Study, which had
considered only an open pit operation. The main objective of the current
drilling programme is to enable mineral resources currently classed as
'indicated' in the Feasibility Study to be reclassified as 'measured' and, in
addition, potentially to increase the overall resource base and thus the mine
life. The 2007 NI 43-101 gold resource was estimated at 1.4 million ounces
(13.533 million tonnes of measured and indicated resources grading 3.18 g/t
gold).
In 1Q 2008, the Company commenced a mineral resource/reserve delineation
drilling programme, focussing initially on the Larjor Zone, the first results of
which are now to hand. In all, 4,485m of drilling have been completed to date
under this programme. Assay results from holes drilled under the Kinjor and
Marvoe zones, further to the east, are expected by month end. The programme
comprises a series of close-spaced drill holes at a depth of around 200m below
surface, together with two holes drilled to about 500m below surface under
Larjor to test for very deep extensions to the mineralisation. Shear-controlled
gold deposits of Archaean age, like New Liberty, are typically characterised by
a considerable third dimension at depth, now being investigated at New Liberty
for the first time.
All eight holes under Larjor intersected the sheared ultramafic schists hosting
the mineralisation at New Liberty, and all of them returned indications of the
presence of the gold zone. Two of the six plus or minus 200m holes returned
extremely good results, namely, intersections of 23m grading 4.85g/t gold and
31m grading 3.59 g/t gold, respectively. The remaining four returned
sub-economic but nevertheless highly anomalous gold zones, the best of which was
in K-121 with 27m grading 0.67 g/t.
The two deep holes under Larjor both intersected the ultramafic rock units at
the anticipated depth i.e. some 450 to 480m vertically below surface, and both
were mineralised. K120 gave the better results with 19m at 1.2 g/t gold
including a 3m section grading 6.2 g/t. A complete list of the assay results
appears in Table 1 below. This is considered an extremely encouraging outcome
for the potential to increase resources, given that of the 93 holes forming the
basis for the 2007 Feasibility Study, none were drilled significantly deeper
than 100m below surface.

In addition to the work going on at New Liberty, the Mineral Corporation of
South Africa recently completed an in-depth review of the entire exploration
database for the Company's MDA licence area, defining further gold targets
potentially capable of development into satellite deposits to New Liberty. These
targets are in addition to the Weaju and Gondoja satellite deposits, where
drilling has already taken place with encouraging results.
Community Initiatives
During the exploration phase on the Bea MDA, in addition to direct employment by
Mano of local people which at times has totalled over fifty individuals, local
communities have already benefited from a major ongoing programme of road and
bridge building. At Weaju, the Company has built a school capable of
accommodating over 100 pupils.
In the longer term, once the new mine is in production, the communities of Grand
Cape Mount and adjacent counties stand to benefit from what is scheduled to
become Liberia's first ever major hard-rock gold mine. In addition to the many
direct employment and training opportunities, there will be indirect employment
from sustained activities, which it is hoped may include linking the New Liberty
gold deposit at Kinjor/Larjor to Mano's Weaju project. Social infrastructure
improvements would include power, educational and health provisions, and better
local roads. Experience elsewhere in the world suggests that, for every direct
employee at the new mine, there will be from 5 to 10 further jobs created in
support and service industries in the immediate area. Agricultural projects
related to the communities are also contemplated.
Mano has been pioneering hard-rock exploration for gold in Liberia since access
to the licence was first gained in the second half of 1997, more than 10 years
ago and, despite interruptions, the Company has persevered in its aim of moving
its projects closer to feasibility. Many exploration companies have been
motivated by Mano's prime mover publicity for Liberia, and there are now more
than 10 gold exploration companies active in the country. It is hoped that Mano
will continue to lead the way by opening the first of many new gold mines in
Liberia over the next 10 years.
Luis da Silva, CEO of Mano, comments: "This first phase of our deep drilling
programme has yielded encouraging results, which have backed up the predicted
nature of the New Liberty ore body and potentially give us the ability to
significantly increase the resource ounces of gold. A further programme of
drilling will now be planned to provide definition for resource modelling.
Underground mining methods will also be investigated as part of conducting a
comprehensive new feasibility study for NLGM, with completion in 2009."
Note to Editors
Overview of the New Liberty Gold Project
The 2007 New Liberty Feasibility Study, exclusively for an open pit operation,
was undertaken by independent consultants, MDM Engineering Pty Ltd of
Johannesburg, South Africa, together with Lower Quartile Solutions Pty Ltd of
Perth, Australia. Tailings dam design was carried out by Golder & Associates.
The geology of the deposit is a well-defined steeply dipping zone up to 30m
thick of gold mineralisation hosted by metamorphosed ultramafic schists. The
base case for the Feasibility Study involved open pit contract mining from three
pits, Larjor, Kinjor and Marvoe, over an initial estimated mine life of seven
years. The average stripping ratio was estimated at 11.5 to 1. The deposit
exhibits simple metallurgy with overall gold recoveries of 93% being indicated
by the study testwork, involving a process of initial gravity separation with a
recovery of 30-40% of the gold, followed by standard carbon-in-leach treatment.
Mano's Qualified Person responsible for preparing this release is its Director,
Dr Tom Elder, who holds a BSc and Doctorate in Geology from the University of
Durham in the UK, is a Fellow and former Member of Council of the Institution of
Mining and Metallurgy, and a Fellow of the Geological Society.
