Corporate
The Mofe Creek Mineral Reconnaissance license was awarded to Tawana Liberia
Inc., a locally incorporated company 100% owned by Tawana Resources NL. The
license covers a total area of 285 km2 approximately 100 km north-west of the
capital city of Monrovia.
Under the terms of the Sinoe Project Joint Venture, the Company paid Global
Mineral Investments LLC (`GMI`) a US$50,000 execution payment during the
quarter. This represents the third payment under the agreement terms. The
Company will continue to fund exploration during the first year after which it
has the right to purchase the licence outright or walk away unencumbered.
Liberia
Grid soil sampling and geological mapping was completed over the Sinoe Gold
Project. Significant and prolific artisanal gold workings; both alluvial and
eluvial were discovered in the central northern portion of the license area.
Approximately 2360 soil samples were collected during the quarter on an 800x100m
grid over the target areas and all samples submitted to SGS laboratory in
Monrovia for gold analysis. Full results are expected end February 2012.
The Company secured and commenced field exploration activities on the Mofe Creek
Iron ore Project in Western Liberia. Geological mapping and rock chip sampling
has defined a broad iron bearing unit along a 35 km strike length within the
reconnaissance permit. The License is 10 km along strike from the historic Bomi
Hills Fe ore mine with historic production of 50 Mt high-grade DSO magnetite at
64-66% Fe, 4-6% SiO2, 0.75-1.50% Al2O3 and 0.09-1.00% P. The License is
prospective for high-grade magnetite Direct Shipping Ore (DSO) lump and
weathered soft magnetite iron formation for beneficiation. Potential exists
for rapid development of low capital intensity DSO Fe ore project generating
significant cash flow.
Several high priority stream sediment BLEG anomalies were identified on the
companies Nimba and Lofa projects; two mineral permits issued in December 2010
and formally approved to Gryphon Minerals Ltd (ASX: GRY) on 23rd February 2011.
A large scale robust 10 km strike length target was identified at Nimba and a
6 km strike length target at Lofa. Anomalous target areas were enhanced by
coincident artisanal workings, favourable geology and major structures that
host the 5 Moz Ity mine and 1.52 Moz New Liberty resource.

Sinoe Gold Project
Tawana has secured binding exclusivity and exclusive rights to purchase outright
the Sinoe license pending results of the first year field exploration programme.
Access is via paved and laterite road from Monrovia to Greenville and laterite
road from Greenville to the project area. Under the terms of the agreement, the
Company has secured the services of the vendor`s expatriate site manager to
build access tracks, additional camp facilities and maintain logistical supplies
to facilitate exploration activities.
The mineral exploration license covers 400 km2 of Birimian aged rocks along
arguably the most prospective gold mineralised structure being explored in
Liberia today; the Dugbe Shear.
The project area is 25 km along strike from Hummingbird`s (AIM: HUM) 1.8 Moz
Dugbe Project and 40 km along strike from Equator Resources (ASX: EQU) Bukon
Jedeh Project. Both projects are hosted along secondary and tertiary structures
adjacent to the main Dugbe Shear. Similar structural targets have been defined
in the government regional aeromagnetics data over the Sinoe Project area.
The area is characterised by numerous artisanal alluvial and eluvial gold
workings. The area is also characterised by numerous quartzite, graphite and
manganese occurrences on the USGS Geological map of Liberia; all favourable
indications for gold prospectivity.

Since field work commenced in late August 2011, field teams have completed soil
sampling over the target area for a total of 3300 samples on an 800x100 m
sampling grid of which 2360 were collected this quarter. All samples have been
submitted to SGS Laboratory Liberia and full results expected end February 2012.
Field mapping of access, artisanal workings and geology has continued in
parallel with sampling activities. Mapping has highlighted an interpreted fold
closure within biotite and biotite-garnet schists and increased pegmatite
intrusive sills and dykes in the central-northern portion of the license. This
area coincides with increased artisanal activity over several kilometres in
both alluvial and eluvial settings. This area is considered highly prospective
with reconnaissance sampling returning up 1g/t gold in soil samples.
Mofe Creek Iron Project
The mineral reconnaissance license covers 285 km2 over Grand Cape Mount and Bomi
Counties in Western Liberia and is approximately 100 km drive from Monrovia on
well-maintained sealed roads, 20 km from an historic heavy-haul iron ore railway
and deep sea port and 25 km from the coast. Access to the project area is
excellent with both sealed and laterite roads traversing the license area which
is characterised by low, undulating topography and widespread shrub.

The Mofe Creek license is 10 km along strike from the abandoned Bomi Hills iron
ore mine. Historic production at Bomi Hills is poorly documented; however
estimated historic production by the Government of Liberia is 50 Mt of
high-grade magnetite (Elenilto Minerals and Mining website).
Bomi Hills produced high-grade direct shipping ore (DSO) magnetite lump
in addition to magnetite concentrate beneficiated from itabirite
(metamorphosed and re-crystallised banded iron formation).DSO magnetite
lump averaged 64.5% Fe, 4.5% SiO2, 1.5% Al2O3 and 0.13% P, of which 53%
formed lump material (average 11-37mm) and 47% formed fines (<11mm).
The beneficiated low grade itabirite concentrate averaged 64% Fe, 6% SiO2 and
0.04-0.05% P and was used to produce sinter feed.
The genesis of the Bomi Hills magnetite deposit is not clearly understood,
however, general consensus is that it is hypogene and represents an itabirite
that has come into direct contact with rising gneissic fronts and deep seated
intrusions causing enrichment to coarse massive magnetite by metamorphic
differentiation. Magnetite mineralisation is in direct contact with gneissic
basement and is partially blind. Similar settings are noted at Mofe Creek.

The iron formation is medium to coarse grained, sugary laminated quartz-
magnetite +/- hematite with an average grain size of 2-5mm at varying degrees
of weathering. Where strongly weathered, the material is less magnetic and
easily crumbled by hand to liberate iron oxides from quartz gangue. From
approximately 70 rock chips sampled to date, the iron formation averages 35-50%
Fe, 45-20% SiO2, 0.7% Al2O3, <0.01% P2O5, 1.32% LOI and has been mapped over 35
km of strike. No sulphur and below detection or at detection limit Ti, V or Cr
was recorded within the samples.
Metre scale outcrops of massive magnetite were also observed within the license
area further enhancing the exploration model for hypogene, massive magnetite
bodies like Bomi Hills. High-grade weathered friable hematite/magnetite and
massive magnetite sampled in outcrop within the license area returned on average
63.8% Fe, 3% SiO2, 2.4% Al2O3, 0.08% P and 2.6% LOI in 2 samples. This
demonstrates the hypogene magnetite potential similar to Bomi Hills and further
enhancing prospectivity.

grade, clean magnetite/hematite fines.
All samples were assayed by SGS Liberia and were sourced from in-situ
outcropping material, were dried and crushed to a nominal 2 mm using a jaw
crusher then the whole sample pulverised in a LM2 to a nominal 85% passing 75
Nm. A 200g sample was then scooped, with iron ore analysis of majors and minors
by borate fusion-XRF.
On the basis of preliminary reconnaissance mapping and analogies drawn with Bomi
Hills 10 km along strike, the company is targeting both massive, high-grade DSO
magnetite lump mineralisation and weathered, easily beneficiated `soft` iron
formation for high-grade beneficiated fines.
Both styles of mineralisation have been confirmed in the license area.
On the basis of initial mapping and sampling results, the Company plans to fly a
detailed aeromagnetics survey to better define mineralisation distribution,
structure and continuity below areas of thick vegetation and/or weathering.
There is significant potential for this project to provide a rapid development
timeframe, with low capital intensity utilising the extensive existing
infrastructure and close proximity to major deep water ports and/or transhipment
solutions. Subject to further detailed geological confirmation, a conceptual
target is to quickly develop a high margin, low tonnage operation that could
generate significant cash flows for the Company.
The license area is well positioned for possible future infrastructure
scenarios; road or rail to the Monrovia deep sea port or road to coast and
transhipment via barge to deeper water for onward shipment. A well-maintained
100 km long sealed road exists from the central licence area to the city of
Monrovia. In addition to this an historic heavy-haul iron ore railway* exists
from the Bomi Hills mine to the port of Monrovia; 20 km east from the
easternmost magnetic anomaly. Rail distance from Mofe Creek to the port of
Monrovia is 65 km.
Nimba and Lofa Gold Project
Results for the stream sediment BLEG sampling programmes over Nimba and Lofa
were received during the quarter. Clustering of gold anomalies was observed in
the south of the Nimba tenement area. In addition gold anomalies were
scrutinised and ranked by evaluating their multi-element geochemical signatures
based on relative metal concentrations. Clear multi-element geochemical
signatures (Au+Ba+Ga/La+Pb and Au+Cu+Fe+Pb+Ti+V) were observed with peak gold
anomalism, providing confidence that the stream sediments substantially sampled
bedrock and that the gold anomalies are genuine. Peak anomalies were recorded at
16 ppb; 16 times higher than background gold levels of around 1ppb. These
factors combined provide confidence that results are robust and defining
anomalism associated with upstream gold mineralisation.
The strongest gold response in the SW corner of Nimba is defining a +10 km
strike length ridge and two smaller sub-parallel ridges on either side of the
main trend. These target areas are further enhanced by increased artisanal
mining activity downstream, coincident topographic and magnetic highs and
favourable structural and lithological settings.

highest to lowest), sample point (floating ball) and Au assay (in ppb). Note
clustered anomalism in streams draining the southern and central portions of
the ridge line with dominant anomalism along the eastern flank. Image draped
over Google Earth imagery.
At Lofa peak gold anomalism was reported at 8.6 ppb; 8.5 times higher than
background gold levels of around 1ppb. Clustering of anomalies was observed
within streams draining a discrete 6x3 km area of hills in the north-west of the
tenement area. Anomalies were scrutinised further and multi-element geochemical
signatures defined, with the strongest gold response associated with a
Au+Ba+Ga/La+Pb signature as per Nimba in addition to a Cu-Ni-Cr-V-Ti-Fe metal
association suggesting a mafic/ultramafic lithological host.
Ultramafics have not been recorded on the government USGS regional geological
map; however, native Cu mineral occurrences are recorded on the northern licence
boundary immediately adjacent, further supporting and enhancing the anomalous
area.

Stream sediment samples were collected using a Bulk Leach Extractable Gold
(BLEG) methodology which is designed to minimise "nugget effect" sampling issues
and increase repeatability. The BLEG methodology used is specifically designed
to highlight mineralisation signatures from large hydrothermal gold systems
whilst filtering out the effects of small, high-grade systems that can generate
costly and time consuming false anomalies. It is effective in tropical
environments where there has been long lived deep weathering and erosion
creating significant dispersion trains.
All samples were submitted to OMAC Stewart Group laboratory for gold and
multi-element geochemical analysis. Gold analysis was by low level BLEG using
accelerated active leach with leach aid (DL 0.1ppb) and multi-element
geochemical analysis was by Aqua Regia digest and combined Inductively Coupled
Plasma with Atomic Emission Spectrometry or Mass Spectrometry (ICPAES/MS)
finish.
Results received have passed internal and external QA/QC procedures and are
within reporting error limits of certified standards providing confidence in
reported results.
Work Plan going forward
Pending results infill soil sampling on a 400x50 and 200x50 m grid in
conjunction with trenching is planned at Sinoe over the following quarter.
Pending results drilling of subsequent target areas is planned.
Field mapping will be completed at Mofe Creek along the western portion of the
license area. Pending results of mapping and rock chip sampling, an aeromagnetic
survey is planned over the license area to define iron formation limits,
lithology, structure and degree of weathering. Both the geological mapping and
airborne survey will be used to plan pitting and trenching and pending results
drilling of subsequent target areas is planned.
A soil sampling programme has been planned to cover the newly identified target
areas. Field teams are currently being mobilized. Pending results, infill soil
sampling and trenching followed by drilling of subsequent target areas is
planned.
About Liberia
Liberia is a democratic country run by Her Excellency President Ellen Johnson
Sirleaf; Africa`s first elected female head of state in 2005 and recently
re-elected in November 2011 for her second term. The country is hugely
prospective and hosts several world class iron ore deposits but yet is
completely underexplored for gold and non-ferrous metals. Liberia has a
modern and transparent mining code and the government is supportive of foreign
investment especially in the exploration and mining industry to help unlock the
value of its potential mineral wealth. Tawana will be one of the first ASX
listed junior companies into Liberia following in the footsteps of mining majors
BHP Billiton, Arcelor-Mittal and Severstal.
Liberia is located in West Africa dominantly within the Archean aged Kenema Man
Domain and lesser Birimian sediments to the east. There are a large number of
world class mineral deposits located in the Archean and Birimian rock types
throughout West Africa including Obuasi (40 Moz+) and Tasiast (18 Moz+). West
Africa is one of the fastest growing mineral provinces in the world and Liberia
currently hosts several world class iron ore deposits and is underexplored for
gold.
