             New Mineralisation Targets Discovered

PLEASE NOTE: ALL GRAPHICS HAVE BEEN REMOVED FOR SENS PURPOSES. PLEASE
REFER TO TAWANA WEBSITE FOR THE COMPLETE ANNOUNCEMENT.

Tawana Resources NL (‘Tawana’ or ‘the Company’) is excited to announce the
recent discovery of new and additional iron ore mineralisation identified
from outcropping iron formations at both the Koehnko North East (NE) and
Koehnko East (E) prospects within Tawana’s 100% owned Mofe Creek project
(the Project) in Liberia.

The Koehnko NE and Koehnko E prospects are both located within 5kms of the
Koehnko hub’s maiden inferred resource of 16.2 Mt at 31% Fe (refer ASX
release 31st March 2014)1. The mineralisation has been mapped as
predominantly friable itabirite with some higher grade hematite capping,
mostly recorded on the flanks of the hills. From initial field observations, both
prospects have the potential to significantly grow the Koehnko resource
estimate and the overall Project resource base of 61.9Mt at 33% Fe 1. The
Koehnko NE deposit is inferably the largest potential outcropping iron ore
formation discovered to date, across the Company’s 100%-owned Mofe Creek
licences.

The combined strike of mapped surface iron mineralisation is 1.35km with an
average grade of 35% Fe determined from rock chip samples analyzed by hand
held XRF. These two prospects represent the first areas explored since the
resumption of field based exploration. This low cost form of exploration
continues to generate and firm up exploration targets to aid in prioritising
future drilling programs targeting additional resource tonnage.

Executive Chairman and Chief Executive Officer Mr Wayne Richards said “These
exciting results, along with the Company’s recent Direct Shipping Ore (DSO)
discoveries, are extremely encouraging and further strengthen the exploration
rationale for a potential Bomi Hills analogue within our two 100%-owned
tenements”.

Koehnko North East (NE) Prospect

The Koehnko NE prospect is currently defined by outcropping iron formations mapped
over a surface expression with an approximate strike length of 850m at an average
width of 80m. From rock chip samples taken from the outcropping itabirite, which also
is the largest outcropping iron formation observed in the Project to date, and analyzed
by hand-held XRF the assays ranged in grade from 22.3% to 57.3% Fe with an average
grade of 35% Fe, 1.35% AL, 0.057% P, and 0.11% S.

Koehnko East (E) Prospect

The Koehnko E prospect is located 15km along strike from the historical Bomi Hill Iron
Mine, which produced in excess of 50Mt of DSO during the 1950’s-70’s, and is
interpreted to be a possible western extension of the iron formation.
The Koehnko E prospect consists of iron mineralisation mapped over a high hill with a
strike length of 500m at an average width of 30m. The rock chip samples collected
from the defined iron mineralisation footprint ranged in grade from 26.7% to 50.9% Fe
with an average grade of 35.8% Fe with acceptable impurity levels of 1.92% Al, 0.05% P,
and 0.05% S.

Within the 10km window of the Koehnko E prospect to the eastern boundary of
Tawana’s MEL12029 licence intermittent magnetic anomalies interpreted to be
extensions to the Koehnko East prospect are currently being mapped and sampled by
Tawana’s field crew.

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 is a
new discovery in the heart of Liberia’s historic iron ore district, located 20km from the
coast and 85km from the country’s capital city and major port, Monrovia.
Tawana is committed to advance the development of its 100% owned Mofe Creek
project, which covers 475km2 of highly prospective tenements in Grand Cape Mount
County. The project hosts high-grade friable itabirite mineralisation, which can be
easily upgraded to a premium quality iron ore product of +64-68% Fe grade, via simple,
low capital intensity beneficiation.

Detailed information on all aspects of Tawana’s project can be found on the Company’s
website www.tawana.com.au.
