High-Grade DSO DiscoveryTawana Resources NL ('Tawana' or the 'Company') is excited to announce the discovery of new high-grade Direct Shipping Ore (DSO) hematite mineralisation, averaging 62.8% Fe and up to
66% Fe, located a short trucking distance to the operating port of Freeport, Monrovia. Additionally the Company has discovered greater than 2.2km strike of friable itabirite mineralisation in the Goehn prospect as part of its ongoing low-cost exploration strategy over the Company's recently acquired, 100% owned MEL1223/14
Mofe Creek South licence.
The new zone of DSO hematite mineralisation occurs within the Goehn South East (SE) prospect, within a broader >550m strike length of friable, coarse-grained itabirite, with potential for additional strike extensions.
Itabirite mineralisation of greater than 2.2km combined strike length, ranging in grade from 26.4% to 52.6% Fe, has also been delineated. This represents one of four additional high-priority target areas defined within the Mofe Creek South licence area. The itabirite mineralisation defined has similar geological characteristics to the 61.9Mt at 33%1 Fe maiden resource estimate and is within
8km trucking distance thereof, and is within close proximity of a
bitumen highway.
Executive Chairman and Chief Executive Officer Mr Wayne Richards said "This target represents the highest grade, continuous zone over multiple samples, of DSO hematite mineralisation discovered within the project area to date. It represents a fantastic result for the Company and an exciting potential low-cost, early development opportunity within short trucking distance to the operational port of Monrovia." Mr Richards added "The combination of a new DSO hematite discovery within the Mofe Creek project area and the recently announced port infrastructure MoU signed with WISCO-CAD significantly enhances the potential for a low-capital intensity, early start-up DSO trucking operation. This is a potential game-changer for both the project and the Company."
The results strengthen the exploration rationale for a potential Bomi Hills analogue, which historically produced in excess of 50Mt of DSO within 35km of the project area.
Tawana continues its strategy of low-cost, value-add exploration work by its in-house team while advancing core negotiations with the Government of Liberia for the Mineral Development Agreement and progressing strategic Environmental and Social Impact Assessment activities, including the Terms of Reference document and Scoping Report.
ASX RELEASE | 8th July 2015
MEL1223/14 - DSO at Goehn Target
Low-cost mapping and rock-chip sampling over MEL 1223/14 has continued to define and prioritise potential additional resource tonnage targets for the Mofe Creek Project.
Since announcing the new mineralisation discovered south of the Gofolo mining hub2 and over the Zaway South target3, field teams have rapidly advanced and defined DSO mineralisation over the Goehn South target.
Figure 1 | Southern licence exploration target areas (circled yellow), known resource footprints (pink)
and Northern licence targets (red and orange), over a Digital Elevation Model (DEM) image background.
Detailed mapping and rock chip sampling over the Goehn South target has defined a significant area of high-grade hematite DSO mineralisation in addition to greater than
2.2km strike of itabirite mineralisation (refer Figures 2, 3 & 4 below).

A significant 120m x 100m area of hematite DSO mineralisation (solid pink area in Figure 4 below) at average 62.8% Fe and up to 66% Fe in seven rock chip samples analysed using hand-held XRF, has been discovered in the Goehn SE prospect.
High-grade hematite DSO mineralisation occurs within a broader greater than 550m strike itabirite mineralized zone at average 52.7% Fe in 27 rock-chip samples. Potential remains for additional DSO mineralisation within the broader itabirite envelope as well as along strike within the Goehn target.

ASX RELEASE | 8th July 2015
These results are highly encouraging and represent a potential Bomi Hills-type DSO discovery with scope for depth and strike potential. This is significant as the DSO mineralisation may continue at depth and extend well below depth of weathering; similar to the hypogene magnetite DSO mineralisation mined at Bomi Hills. Bomi Hills produced in excess of 50Mt of DSO during the 1950's-70's and is located 35km along
strike from the project area4.

Figures 6 & 7 | Example of surface outcrop and close-up of DSO mineralisation grading 65.1% Fe in rock- chip at Goehn SE prospect.
In addition to the high-grade DSO mineralisation discovered, a combined strike length of greater than 2.2km of itabirite mineralisation averaging between 26.4% Fe to 54.6% Fe in 52 hand-held XRF rock-chip samples has been defined within the Goehn South prospect.
The itabirite mineralisation mapped is coarse grained with low contaminant levels and occurs in outcrop along coincident magnetic and topographic highs, similar to the known resource footprints directly north (refer Figure 3).
The target areas delineated have significant potential to add additional resource tonnes to the project, including the potential for early start-up DSO material.
ASX RELEASE | 8th July 2015
Mapping teams will continue to assess remaining exploration targets within the license area with the aim of prioritising drill targets with the highest potential to increase the current resource from 61.9Mt to 120Mt5.
Enhanced Low Capital Early Start-Up Scenario
The DSO mineralisation defined within the Goehn South prospect falls within 6km of the bitumen road between the Project area and the operational port of Monrovia; only
75km away. This new discovery represents a strategic opportunity to structure an early-start-up operation with minimal capital intensity, using the existing highway and a working port within Monrovia. The mineralisation is readily accessible and presents
from surface.
Likewise, the Goehn deposit is geographically more closely located and aligned with the proposed longer-term independent haul road and Greenfield port location, than either the Gofolo Main or Zaway Main deposits; thus enhancing potential project value. The deposit also supports the opportunity for an early start-up, low-capital intensity mining and trucking operation within the initial years of production and project life cycle. Due to the hematite DSO style mineralisation discovered, a beneficiation process may not be required at start-up and will only be introduced as the mineralisation transitions from DSO into friable itabirite mineralization. This mining methodology ensures the delayed capital requirements of a processing facility and allows the wet plant to be potentially funded from cashflow and/or strategic debt, once the Company is operational and generating an income.
This potential development is further enhanced by the recently announced infrastructure sharing MoU executed between the Company and WISCO-CAD; the owner-operator of the Monrovia port iron ore handling facilities (refer ASX announcement of 18 May 2015).
Field mapping teams are continuing work along remaining targets towards the east and ongoing results will be reported as they become available.
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.
