- David Frances appointed as Executive Chairman
Mr David Frances joined Tawana on 29th January 2013 having been involved in the international
mining industry for over 20 years. He was, most recently, President and CEO of Mawson West Ltd,
where over the past seven years he led Mawson through the transition from a Western Australian
gold explorer to an international copper explorer, developer and producer in the Democratic Republic
of Congo. It is currently envisaged that Mr Frances will revert to a non-executive Chairman role once
the Managing Director has the appropriate executive team in place.
Concurrent to the appointment of Mr Frances to the Board is the resignation of Non-executive
Chairman, Mr Warwick Grigor. The Board and the Company would like to express its sincere
appreciation and gratitude for Mr Grigor’s contribution as both a director and Chairman during his
appointment. Under Mr Grigor’s Chairmanship, the Company has transitioned into an exciting West
African iron ore explorer. The entire Board thanks Mr Grigor for his leadership and wishes him all the
best in his future endeavours.
A 2500m maiden RC drill programme was completed at the Mofe Creek Iron Project during the
quarter and a Global Exploration Target Size Potential estimate* of 500Mt friable iron formation was
announced during the quarter. This represents a significant milestone for the company and a new iron
ore discovery in Liberia very close to the coast.
A 400 hole hand auger programme was commenced at the Sinoe Gold Project to follow up trench
intersections including 12m at 2.4g/t Au and high priority soil anomalies.

All holes were logged on 1m intervals and assayed at 2m intervals. Field duplicates and certified
standards were inserted every 50th sample. All samples were dried and matt rolled to 3.35mm with a
200g split retained for preliminary metallurgical test work and a second split sent for assay of major
and minor elements by XRF fusion. All batches passed internal and external QAQC procedures.
All drill holes intersected variable widths of friable itabirite or friable intermixed itabirite and
amphibolite from surface passing downwards into a mixed sequence of granodiorites and
amphibolites that are variably garnetiferous before passing into basement gneiss.
Higher grade mineralisation appears to be associated with a friable itabirite unit occurring within a
mixed sequence of itabirites and amphibolites. Where folded and at surface, mineralisation is
characterised by coarse grained, friable magnetite and quartz (hole GMRC006, 0-40m @ 50% Fe and
KRC012, 0-34m @ 42.8% Fe). At depth where the itabirite is not folded or weathered it is
characterised by extremely high magnetic susceptibility readings averaging 2,000 SI units and up to
7,000 SI units.
Lower grade mineralisation appears to be associated with a mixed sequence of itabirite and
amphibolite; where weathered at surface it is characterised by elevated Al2O3 (hole GMRC004, 0-40m
@ 30.3% Fe and GMRC005, 0-32m @ 34.3% Fe).
DSO and near DSO grades intersected in holes GMRC006 and KRC012 respectively are interpreted
to be associated with more massive crystalline magnetite occurring at fold closures within the upper
itabirite sequence. Similar structural and lithological settings are recorded at Bomi Hills where heat
from rising gneissic fronts is also considered to be a control. Target areas with the right lithological,
structural and potential heat sources below have been defined within the Mofe Creek project area.
The potential for blind DSO magnetite discovery in the project area is considered to be high.
Global Exploration Target Size Potential*
Results of the maiden 2,500m RC drill programme, detailed aeromagnetics survey, field mapping,
rock chip and hand auger sampling has allowed for a detailed assessment of the exploration target
size potential of the Mofe Creek Iron Ore Project in Liberia, West Africa.
Two broad styles of mineralisation have been intersected to date from surface; friable itabirite and
mixed friable itabirite and amphibolite. Both styles of mineralisation likely result from surface
weathering and softening of the parent rock type; ‘protore’. Where intersected to date, the friable
itabirite is characterised by higher iron grades (35-60% Fe) and low contaminants (avg. 31% SiO2, 5%
Al2O3, 0.05% P, 4% LOI) whereas the intermixed friable itabirite and amphibolite is characterised by
lower Fe grades (25-35% Fe) and elevated Al-LOI-Ti (avg. 40% SiO2, 11% Al2O3, 0.04% P, 7% LOI,
0.2% TiO2). The latter is considered to be associated with clays derived from tropical weathering of
the amphibolite. Folding and faulting of the protores appears to result in higher Fe grades within the
A global exploration target size potential of between 360Mt to 670Mt of friable mineralisation has been
estimated for the Mofe Creek project area. This estimate includes both friable itabirite and friable
intermixed itabirite/amphibolite mineralisation from surface only. The estimate does not include hard
itabirite, potential blind DSO or additional mineralisation associated with geophysical targets
(highlighted in yellow) which have not had sufficient field work to date to justify inclusion.
Targets highlighted in blue are considered to have a greater probability that the full stratigraphy is
preserved; whereas intermixed itabirite/amphibolite only targets are highlighted orange as described
in the targeting rationale above. The split between itabirite and mixed itabirite/amphibolite
mineralisation within the ‘blue’ footprints is determined on an average 50:50 split based on sectional
interpretation from drilling to date.

Total Exploration Target Size Potential Lower Range Upper Range Avg. Grade
Friable Itabirite 90 Mt 230 Mt 40-45% Fe
Mixed Friable Itabirite/Amphibolite 270 Mt 440 Mt 25-35% Fe

Although the potential for blind, massive crystalline magnetite DSO similar to the 50Mt @ >65% Fe
mined historically at Bomi Hills 20km to the east of the project area has not been overlooked; at this
early stage it is not considered possible to provide meaningful estimates of size potential and so is not
included in the figures below. However, the potential for blind DSO at Mofe Creek is considered high
due to its position directly along strike from Bomi Hills, similar host rocks intersected in recent drilling
and the occurrence of isolated DSO in outcrop.
No exploration target size potential estimates for hard itabirite have been defined at this stage as the
Company sees significantly greater value in friable itabirite due to reduced mining and processing
costs and lower capex associated with mining soft material. All estimates are for friable mineralisation
from surface only.
Highly Prospective District Geology
[Historic ‘Western Cluster’ iron ore province and associated deposits and infrastructure over regional
aeromagnetics image has been removed for SENS purposes.]
The Mofe Creek Project is located within one of Liberia’s historic premier iron ore mining districts. The
project is 10km along strike from the abandoned Bomi Hills mine (>50Mt DSO @ 65% Fe plus SF),
80km along strike from the historic Bong Mine (>275Mt @ 38% Fe), 45km from the Mano River mine
(100Mt @ 52% Fe) and 20km from the Bea Mountain resource (>100Mt @ 45% Fe).
Infrastructure and Access
The Project is approximately 20km from the coast and the most likely development scenario would
see construction of a haul road for trucking of product to the coast and transhipment via barge or
conveyor to deeper water for on shipment. Other possible infrastructure solutions exist; road or rail to
the deep water port of Monrovia; a 100km long sealed road exists from the central licence area to the
city of Monrovia. In addition to this a decommissioned standard gauge iron ore railway alignment
exists from the Bomi Hills mine to the port of Monrovia; 20km east from the easternmost magnetic
anomaly. Rail distance from Mofe Creek to the port of Monrovia is 65km.

Sinoe Gold Project
The mineral exploration license covers 400km2 of Birimian aged rocks along arguably one of the most
prospective gold mineralised structures being explored in Liberia today; the Dugbe Shear. The project
area is 25km along strike from Hummingbird’s (AIM: HUM) 3.8Moz Dugbe discovery and 40km 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 and similar structural settings
exist over the Sinoe Project area.
The geology of the Sinoe area is characterised by a package of gently dipping biotite and garnet
biotite schists, intruded by cm to >10m scale pegmatite dykes and sills, mafics and late granitic
intrusives. Best trench intersections received during the previous quarter are 12m at 2.3g/t including
4m at 6.25g/t Au and 24m at 0.4g/t including 8m at 0.87g/t Au
A 400 hole hand auger programme was designed during the quarter and field teams mobilised post
completion of the Mofe Creek maiden RC drill programme. Approximately ¾ of the 400 hole
programme has been completed to date.

Work Plan going forward
At the Mofe Creek iron project, hand auger drilling will continue through the following quarter to
assess additional exploration target areas. Pending results and funding, exploration drilling is planned
along the highest priority targets. Access will be extended at the Gofolo and Koehnko target areas for
a resource drilling programme to commence during Q2 2013 with a JORC compliant resource defined
and high level Desktop study by end 2013. Existing RC drill samples will be composited for
metallurgical test work with results expected during second half 2013.
The 400 hole hand auger programme currently underway will be completed at the Sinoe Gold project
and assay results received during the following quarter.
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.
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 (40Moz+) and Tasiast
(18Moz+). 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.
