New High-Grade Mineralisation Discovery Enhanced DSO
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
high-grade mineralisation at the Company’s recently acquired, 100% owned MEL1223/14
Mofe Creek South licence. This “Zaway South” prospect, incorporates grades of up to 61.6%
Fe - Direct Shipping Ore (DSO) mineralisation, in addition to coarse-grained, friable
itabirite mineralisation over a strike of greater than 4.5km.
The new high-grade mineralisation of potential DSO grade and quality has been defined
over a 900m x 250m area, enhancing the prospectivity for further DSO discoveries.
Mineralisation remains open to the east and is coincident with a 2km-long hill, where
strong potential remains for additional itabirite mineralisation to be defined.
Additionally, greater than 4.5km of combined strike length of coarse-grained itabirite has
been delineated within the adjacent mineralised zones within this area (Refer Figure 4).
These discoveries within the newly acquired licence area, collectively represent just one
of four high-priority target areas defined within the overall Mofe Creek southern licence
area. The itabirite mineralisation defined, has similar geological characteristics to the
61.9Mt at 33%Fe maiden resource estimate at the flagship Gofolo Main and Zaway deposits
located on adjoining Licence MEL 12029 (refer ASX release 31st March 2014) and are within
a 3km trucking distance of the latter deposit.
Executive Chairman and Chief Executive Officer Mr Wayne Richards said “To define DSO
grade mineralisation at surface within our new tenement, is a very encouraging result for
the Company. This represents an exciting development opportunity and enhances the
potential for further DSO discoveries within the tenement. This likewise vindicates the
exploration rationale for a potential Bomi Hills analogue, which historically produced in
excess of 50Mt of DSO from a mine geographically located within 35km of our Mofe Creek
Mr Richards added, “The potential to add value to the Project and expand the Project’s
current resource at a low incremental cost is extremely compelling.”
Tawana is advancing its exploration programme within the new tenement (MEL 1223/14) in
support of the Company’s current corporate strategy of completing low-cost, value-
accretive exploration work with its in-house exploration and geological teams.
In other recent Company developments, negotiations associated with the advancement of
the Mineral Development Agreement culminated with a presentation by Tawana to the
Inter Ministerial Concessional Committee on 9th April 2015 (Refer ASX release 14th April
Likewise, the community stakeholder meetings and environmental baseline reviews for the
submission of an ESIA Terms of Reference document and Scoping Report (refer ASX release
21st April 2015) confirms the Company’s proactive approach to advancing the Mofe Creek
MEL1223/14 - Zaway South Target & DSO Fe Grades
Tawana’s in-country exploration teams have continued their low-cost mapping and rock-
chip sampling program over MEL 1223/14 to define and quantify potential additional
resource tonnage targets.
Since announcing the new mineralisation discovered directly south of the Gofolo mining
hub (refer ASX announcement 8th April 2015), field teams have rapidly progressed and
completed mapping over the Zaway South target.
Mapping teams continue to assess remaining exploration targets within the new licence
area with the aim of prioritising drill targets with the highest potential to increase the
Detailed mapping over the central Zaway South target has defined multiple target areas
including DSO mineralisation associated with surface enriched ferruginous carapace and a
combined >4.5km strike length of itabirite iron formation
A large 0.9 x 0.25km area (refer red hatched area in Figure 4) of surface enriched
mineralisation including DSO grade material up to 61.6% Fe and averaging 49.2% Fe in 20
hand-held XRF samples has been delineated in the eastern margin of the Zaway South
prospect. Mineralisation remains open to the east with potential to further expand the
surface mineralized zone.
These results are highly encouraging and provide additional support in the prospectivity
and potential for a DSO discovery; similar to that mined historically at the Bomi Hills Mine.
Bomi Hills produced in excess of 50Mt of DSO during the 1950’s-70’s and is located 35km
along strike from the project area (refer ASX release 3 December 2012).
In addition to the DSO mineralisation discovered, a combined strike length of >4.5km of
itabirite style mineralisation at average 27.5% Fe in 30 hand-held XRF rock-chip samples
has been delineated within the Zaway South prospect. The style of mineralisation observed
is similar to the known resource footprints with coarse grained itabirite at low contaminant
levels occurring in outcrop along coincident magnetic and topographic highs.
All targets within the Zaway South prospect fall within a 3km trucking distance of the
Zaway Main resource footprint and within 2km of the proposed transport infrastructure
corridors. The target areas have significant potential to add additional resource tonnes to
the project, in addition to enhanced DSO prospectivity.
Field mapping teams are continuing exploratory work along the remaining targets towards
the east of the Zaway South deposits, and ongoing results will be reported as they become
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
