New Mineralisation Discovery - Extending Potential Resource Targets for the Mofe Creek
PLEASE NOTE: ALL GRAPHICS HAVE BEEN REMOVED FOR SENS PURPOSES. PLEASE REFER
TO TAWANA WEBSITE FOR THE COMPLETE ANNOUNCEMENT.
Tawana Resources NL (the Company) is very pleased to announce the discovery of new
mineralisation as part of its ongoing exploration strategy over the Company’s recently
acquired, 100% owned MEL1223/14 Mofe Creek South licence.
New friable itabirite mineralisation has been defined in outcrops over a combined
1.4km strike length and at an average grade of 32.4% Fe. The mineralisation is within a
3km trucking distance of the Gofolo Main resource and is within immediate proximity
to the planned road infrastructure corridor.
The mineralisation represents one of four additional high-priority target areas defined
within the Mofe Creek South licence, which has similar geological characteristics to the
61.9Mt at 33% Fe maiden resource estimate, defined in 2014 (refer ASX release 31st
Executive Chairman and Chief Executive Officer Mr Wayne Richards said “To define
additional high-quality mineralisation within such close proximity to the Gofolo Main
resource and adjacent to our potential first mining hub to be developed, is a fantastic
result for the Company. This represents the first of a series of exciting new exploration
targets which have the potential to add significant resource tonnes to the Project, and
which are within short conveying or trucking distance to the proposed Gofolo-Zaway
mining hubs”. Mr Richards added, “The potential to add value to the Project at a low
incremental cost, coupled with very low stripping ratios and forecast low OPEX costs is
The Company has recently redeployed its full Liberian exploration contingent into the
field to assess new targets to expand the resource footprint of the Project, and to
confirm the potential quantum of mineralisation that may be present within the new
targets. Mapping teams will rapidly assess the remaining exploration targets within the
licence area, with the aim of prioritising drill targets.
Tawana continues its strategy of advancing its envisaged high margin, high-grade ore
project, via such low-cost, value-accretive exploration work carried out by its in-house
team. This strategy, in conjunction with the consistent progress of activities currently
underway which include: advancing negotiations on the Mofe Creek Mineral
Development Agreement; progressing the Project’s Environmental and Social Impact
Assessment activities; and negotiations for infrastructure and transport solutions with
other third party developers/operators, distinguishes Tawana from other global iron
ore companies during this period of low commodity pricing.
MEL1223/14 Exploration Success
Three exploration teams have commenced a two-month mapping and rock-chip
sampling program over MEL 1223/14 to define and quantify potential additional
resource tonnage targets for the Mofe Creek Project.
All coincident topographic and magnetic anomaly highs are within a very short
tramming, conveying or trucking distance of the planned Gofolo - Zaway production
hub and are in close proximity to the proposed transport corridor to the coastal port
location as shown in Figure 1 below.
The reconnaissance and value-enhancing exploratory work has been effectively coordinated
using our in-house Liberian exploration team, in conjunction with our hand-held XRF
machine for chemical analysis.
Mapping teams are rapidly assessing some of the potential exploration targets within
the license area with the aim of prioritising drill targets with the highest potential to
add significant tonnages to our global exploration target of 500 Mt (Refer ASX release
18th March 2013).2
Detailed mapping over the westernmost target has defined 1.4km combined strike
length at an average of 32.4% Fe with low contaminant levels from 19 surface rock chip
samples using handheld XRF (refer Figure 4 below).
The style of mineralisation and tenor observed is similar to the known resource
footprints with friable, coarse grained itabirite at low contaminant levels occurring in
outcrop along coincident magnetic and topographic highs.
Field mapping teams are continuing work along remaining targets towards the east and
ongoing results will be reported as they become available.
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 advancing the development of its 100% owned Mofe Creek
Project, which covers 475km2 of highly prospective tenements in Grand Cape Mount

Exploration - Acknowledgment and appraisal of exploration by other parties. - The Mofe Creek project is a grassroots discovery with no previous mineral LK

Geology - Deposit type, geological setting and style of mineralisation. - The Mofe Creek project is characterised by a series of itabirite hosted iron LK
ore deposits of likely Archean or Palaeproterozoic age as possible strike
continuations of the historic Bomi Hills and Bong Range mines.
- Mineralisation is hosted within banded iron formations (BIFs) that have
undergone regional metamorphism and recrystallization to itabirite and
likely additional recrystallization to coarse grained, coarsely banded
magnetite-hematite itabirite as seen today. A minimum of one and up to
three major itabirite bands are recognised stratigraphically of both silicate
and oxide iron formation facies and interbedded with metasediments
(variably garnet overprinted), Fe rich mafics and quartzites. Collectively the
iron units and interbedded metasediments can be considered a ‘greenstone’
belt that unconformably overlies granite/gneiss basement.
- The sequence has been folded and faulted through at least two major
phases of deformation causing recrystallization, increase in average grain
size and potential enrichment of the itabirite units.
- The sequence has then been subject to intense tropical weathering causing
oxidation of magnetite to hematite, and variable hydration to goethite and
limonite within the upper 30-60m thick weathering profile.
- Some minor faults are recognised in the Gofolo Main prospect but are not
considered to have a major influence on the currently established resource;
they will be incorporated into resource modelling when further infill
drilling has become available.
