Tawana Resources NL (ASX: TAW) (“Tawana” or “the Company”) is very pleased to announce
the discovery of additional broad, mineralised intersections of friable itabirite iron
formations at the Koehnko prospect at its flagship Mofe Creek Iron Ore Project in Liberia.
Managing Director Len Kolff said “Infill and extensional drilling results continue to define
a coherent mineralised itabirite footprint with low contaminant levels at the Koehnko target.”
“Positive drilling observations during the reconnaissance phase programme resulted in Koehnko
drilling being extended and in-filled to 200m x 60m drill spacing in support of a maiden
inferred and indicated resource model” he said.
“Excellent geological continuity was observed in the infill holes and extensional drilling
lead to the drilled mineralised footprint extending to 1.2km long.”
“Significant exploration upside exists within a 2km radius of the currently drilled area with
additional mineralised footprints having previously been defined in hand-auger drilling and
rock chip sampling.”
“Infill and extensional drilling results continue to deliver broad, low level contaminant iron
intersections, providing confidence in upgradability to a +65% Fe premium iron product as reported
in the recent Koehnko metallurgical test work results.” (Refer ASX release of 14th January 2014).
Drilling Results
A total of 10 RC holes for 536m were completed at the Koehnko prospect and all assays received.
Significant drilling intersections are reported in the table below.

Table 1 | Significant intersections from maiden RC resource drilling at the Koehnko prospect
Drilling results have defined a 1.2km strike length, low contaminant level itabirite deposit
along the Koehnko hill. Mineralisation is open to the west and east along the main Koehnko hill,
with additional target footprints yet untested by drilling to the north, east and south.
Contaminant levels within the reported drill intersections are low in Al2O3, P, TiO2 and sulfur,
and are broadly similar to the high-grade itabirite intersections reported at Gofolo Main and Zaway.
Recently completed metallurgical test work on reconnaissance phase drilling at Koehnko last
February (2013) suggests that a +65% Fe and up to 68% Fe premium product is achievable at Koehnko
(Refer ASX release of 14th January 2014). The extensional and infill drill results announced here
confirm similar grades as used for the metallurgical test work providing confidence that a premium
product can be generated for the project area.
Exploration Potential
Significant exploration potential exists within hills to the north, east and south of the main
Koehnko prospect. Hand auger drilling and rock chip sampling has defined over 7km of additional
prospective strike with iron formation in outcrop returning assays between 37% Fe and up to 53% Fe.
Based upon the current aeromagnetic footprints, the Koehnko deposit (in its entirety) has the
potential to be significantly extended from its current size. This mineralization extension upside
at Koehnko, coupled with the additional outstanding anomalies for Gofolo and Zaway, provides confidence
in the potential attainment of the long-term exploration target.
Scoping Study Update
Metallurgical diamond core test work samples from the Maiden Resource drilling campaign undertaken
from October 2013 to January-end 2014, were dispatched from Monrovia on 02 February, cleared
customs and arrived at the ALS laboratory in Perth by 07 February. Approximately 3,000kg of full
HQ drill core will be processed in 10 representative composites of mineralisation from the Gofolo Main
and Zaway prospects. Metallurgical test work is underway with initial results expected over the coming
weeks. Physical testing of the ore has commenced,along with relevant specific gravity and density
testing – to assist with the future mine planning and mining methodology studies.
Resource modelling for the Mofe Creek Maiden Resource Statement is well underway with all results
now incorporated into a database and QA/QC’ed, whilst wire framing is currently well advanced.
A review of the modelling will commence this week, and the resource statement is scheduled to be released end
March/early April 2014.
An environmental, social and community baseline site review and mapping in support of the
Scoping Study was completed on site during February. A preliminary report is being prepared
and will be issued for review in the forthcoming weeks. A scope of works in support of baseline
data requirements for the Pre-Feasibility Study is currently being generated.
A part-time Study Manager has been appointed to Tawana, to champion the coordination and timely
completion of the Mofe Creek Project Scoping Study. The study remains on-track for completion
in early July 2014. Additionally, a part-time Chief Financial Officer has been employed to
structure the Company’s corporate financial systems to effect the timely and accurate migration
of the Company financial systems from an explorer to a future developer. The appointee will also
be accountable for operating the financial model for the Scoping Study and assist with future
financial analyses of various operating scenarios and varying ownership and development scenarios.
Detailed proposals and development scenarios were presented to relevant Ministries and Authorities
within Liberia, confirming Tawana’s business development and execution plans for both an early
start-up scenario (1-2 Mtpa) and the Company’s longer-term 5-10 Mtpa production plan. Discussions
and proposals have also been presented to the existing third-party owner/operators of the Monrovia
deep water port facilities to seek port access and/or port gate/rail siding sales agreements in
support of the early production start-up scenario.
An in-country Manager was appointed and commenced employment at the Project,within Liberia on
February 07 2014. Both the Managing Director and Executive Chairman were in country during
February, to meet with the relevant Ministers,Ministries and Environmental Protection Authority
(“EPA”) to advance the Project and guide the newly appointed Manager in his future roles and tasks.
Both senior executives also attended the recent Indaba Conference in Cape Town.
About Tawana (ASX & JSE: TAW)
Tawana Resources NL is an iron ore focused ASX and JSE-listed Company with its principal project
in Liberia, West Africa. Tawana’s 100% owned Mofe Creek Project (“the Project”) is a new
discovery in the heart of Liberia’s historic iron ore district, located 20km from the coast and
80km from the country’s capital city and major port, Monrovia.
Tawana is committed to becoming a mid-tier iron ore producer through the development of the Mofe
Creek Project, which covers 285km2 of highly prospective tenements in Grand Cape Mount County.
The Project hosts high-grade friable itabirite mineralisation which can be easily upgraded to
a superior quality iron ore product in the 65-68% Fe grade range, for which there is consistent
global demand, attracting significant price premiums.
The Company has concluded its maiden resource drilling program and is well advanced in the
completion of its Scoping Study on the Mofe Creek Project. The Scoping Study will consider both
an early start-up, low capital cost project with a production rate of 1-2 million tonnes per
annum (Mtpa), as well as a longer-term project capable of producing 5-10 Mtpa of iron ore product.
About Liberia
Liberia is a democratic West African country with a modern and transparent mining code and a
government proactively engaged with the mining industry to help unlock the value of its
potential mineral wealth. Her Excellency President Ellen Johnson Sirleaf was Africa’s first
elected female head of state in 2005 and was re-elected in November 2011 for a second term. The
country is hugely prospective for minerals exploration and production, hosting several world-class
iron ore deposits. Liberia has historically been the largest exporter of iron ore in Africa and was
the 5th largest iron ore producer globally during the 1960’s to 1980’s.

itabirite is medium to coarse grained with relict
banded texture and is friable where weathered from
surface to an average depth of 25-45m vertical. In-situ
iron grades are increased where weathered to form an
enrichment blanket from surface to average 25-45m
vertical depth and locally higher iron grades are
associated with primary magnetite accumulations.
