Maiden Lithium Mineral Resource for Bald Hill Lithium and
Tantalum Project

Tawana Resources NL (“Tawana”) and Alliance Mineral Assets Limited (SGX: AMAL) are
pleased to announce a maiden Indicated and Inferred lithium Mineral Resource for the Bald Hill
Lithium and Tantalum Project.
Highlights

- Resource independently estimated by CSA Global Pty Ltd.
- Maiden Indicated and Inferred lithium Mineral Resource of:
       - High grade of 12.8 million tonnes at 1.18% Li2O and 158ppm Ta205 at a 0.5% Li20 cut-
         off.
- High grade tantalum Resources have increased 250% to 8.9 million tonnes at 304ppm Ta2O5
  containing 6 million pounds of tantalum pentoxide, including 5.7 million tonnes at 311ppm
  Ta2O5 not included in the +0.5% Li2O lithium resource.
- Approximately 80% of the lithium and tantalum resources above 0.5% Li20 occurs in a 100m
  deep interval commencing from about 30m below the lowest surface level.
- Maiden Resource covers only 20% of the known southern swarm of lithium pegmatites. Ongoing
  drilling continues to expand the resource footprint.
- The Resource satisfies the condition precedent to the second offtake prepayment with Burwill
  Holdings Ltd, due on 15 July 2017.
- The substantial Resource complements the excellent recoveries from metallurgical test work.
- Feasibility Study completion is imminent.
- First lithium shipment targeted for Q1 2018.

Tawana Resources Managing Director Mark Calderwood stated: “The 18.5Mt of combined high-
grade lithium and tantalum resources is an excellent start from initial drilling at Bald Hill which has
only tested 20% of the initial mineralised target area. Exploration drilling is continuing at Bald Hill
with the intention of providing resource upgrades over the next six months. We are also pleased to
have met the Resource condition precedent of the off-take early.”

Mineral Resource Estimate

CSA Global Pty Ltd (“CSA Global”) was commissioned by Tawana to compile the maiden lithium
Mineral Resource estimate for the Bald Hill Project and update the tantalum Resource.
The Bald Hill Pegmatite Mineral Resource comprises one large, main, sub horizontal pegmatite
body, striking north-south, with a strike length of 1,070 metres, and a width at its widest point of
775 metres. This main body is surrounded by several smaller discrete pegmatite bodies, sub-
parallel to the main, which result in a total strike length for the whole resource of 1,245 metres,
and a total width of 990 metres. The Mineral Resource has a total vertical depth of 195 metres,
beginning 20 metres below the natural surface and plunging gently to the south along its entire
strike length.

The Mineral Resource has been classified as Indicated and Inferred in accordance with the JORC
Code, 2012 Edition on a qualitative basis; taking into consideration numerous factors including
drillholes spacing, estimation quality statistics (kriging slope of regression), number of informing
samples, average distance to informing samples in comparison to the semivariogram model ranges,
and overall coherence and continuity of the modelled mineralisation wireframes. All factors that
have been considered have been included in Section 1 and Section 3 of Appendix 1.

Off Take Condition Precedent 

The CSA Global Mineral Resource estimate at a 0.5% Li2O cut-off (refer Table 1 & 4) satisfies
the tonnage and grade condition precedent to the second and third prepayment due to AMA and
Tawana on 15 July 2017 (Refer Tawana ASX announcement on 26 April 2017 and AMA
Announcement on 27 April 2017) from Burwill Holdings Ltd (Burwill).
Burwill has agreed to advance Tawana and AMA a combined amount of A$25,000,000 in total
(“Advance Payment Amount”) in the amounts, and on the dates set below:
•      A$3,750,000 (to each Tawana and AMAL) was received on signing the Agreement;
•      On 15 July 2017, A$4,375,000 to each of Tawana and AMA; and
•      On 15 September 2017, A$4,375,000 to each of Tawana and AMA.
The Advance Payments shall be used for the development and operational costs of the Bald Hill Project.

Tawana and AMAL has committed all 2018 and 2019 lithium ore concentrate that comes from
the planned Bald Hill Lithium and Tantalum Project for a fix price of US$880/t (FOB
Esperance) for 6% Li2O with price adjustment increment/decrement of US$/15t based on grade
variation of 0.1%. The minimum accepted grade is 5.5%.

Prior Estimates

The current resource estimate supersedes the prior resource as reported in the August 2016
Independent Qualified Person’s Report for AMA, on the Bald Hill Tantalum Project. This prior
estimate was not completed by CSA Global.

Mining scheduling was the last remaining component of the study which is in the process of being compiled.

ASX Listing Rule 5.8.1 Compliance

Geology and Geological Interpretation

The Bald Hill area is underlain by generally north-striking, steeply dipping Archaean
metasediments (schists and greywackes) and granitoids. Felsic porphyries and pegmatite sheets
and veins have intruded the Archaean rocks. Generally, the pegmatites cross cut the regional
foliation, occurring as gently dipping sheets and as steeply dipping veins.
The pegmatites vary in width and are generally comprised quartz-albite- muscovite-spodumene in
varying amounts. Late-stage albitisation in the central part of the main outcrop area has resulted
in fine- grained, banded, sugary pegmatites with visible fine-grained, disseminated tantalite. A thin
hornfels characterised by needle hornblende crystals is often observed in adjacent country rocks
to the pegmatite intrusives. Tantalite generally occurs as fine disseminated crystals commonly
associated with fine-grained albite zones, or as coarse crystals associated with cleavelandite.
The geological model developed is based on lithological logging of pegmatites within a
metasedimentary host, with occasional hypabyssal intrusions of dioritic composition.
The pegmatites on which this Mineral Resource was defined were domained internally on the basis
of a 7,500ppm Li2O cut-off, which itself was determined from exploratory data analysis as a point
of inflection within the Li2O grade distribution. This resulted in a high-grade core of Li2O
mineralisation surrounded by lower grade pegmatite, and is an interpretation supported by the
petrogenetic model for the formation of Li2O bearing pegmatites.

Drilling Techniques

Drilling supporting the Mineral Resource is predominately Reverse Circulation (RC) with minor
diamond core drilling (DD) and RC with diamond core tails (RCD). The Bald Hill deposit database
includes 728 drill holes for 63,539.2m of drilling, made up of 716 RC holes (61,621.2m), 9 RCD
holes (1,660.4m) and 3 DD holes (257.6m). The Mineral Resource is based on assay data from
460 RC holes, 9 RCD holes and 3 DD holes.
All historical holes drilled by Haddington were removed from the estimated as they were only
assayed for tantalum. Some recent drilling undertaken by Tawana has been excluded where collar
and/or down hole surveys have not been completed, and where final assay results have not been
received.

Drilling has been angled to achieve the most representative intersections through mineralisation.
All diamond drill holes and approx. 98% of RC drill holes are angled. The remaining holes have
been drilled vertically. Drilling has been conducted on a 40m by 40m grid extending to 80m by
80m on the peripheries of the deposit, with a 140m by 80m area in the northern portion of the
deposit drilled out at 20m by 20m.

Sampling Techniques

RC cuttings were continuously sampled at 1m intervals from the collar to the end of each drill hole
using a riffle or cone splitter on-site to produce a subsample less than 5kg.
DD core was typically continuously sampled at 2m intervals from the collar to the end of hole.
Where required by changes in lithology, mineralisation or alteration, core samples may be shorter
or longer than the typical 2m. Core was cut into half with one half sent for analysis and the other
half stored in the core library at the project site.

Sample Analysis Method

Drill samples were jaw crushed and riffle split to 2-2.5kg for pulverizing to 80% passing 75
microns. Prepared samples are fused with sodium peroxide and digested in dilute hydrochloric
acid. The resultant solution is analysed by ICP, by Nagrom Laboratory in Perth.
The assay technique is considered to be robust as the method used offers total dissolution of the
sample and is useful for mineral matrices that may resist acid digestions.
Standards and duplicates were submitted in varying frequency throughout the exploration
campaign and internal laboratory standards, duplicates and replicates are used for verification.

Estimation Methodology

The Bald Hill MRE uses a Surpac block model dimensions with parent cells of 10m by 10m by
5m (XYZ) sub-celled to 2.5 by 2.5 by 1.25m for resolution of volumes at lithological boundaries.
This compares to an average drillhole spacing of 20m within the more densely informed areas of
the deposit. Kriging Neighbourhood Analysis (KNA) was conducted within the SupervisorTM
software package to test a variety of block sizes across the deposit.
Samples were composited to 1m intervals based on assessment of the raw drill hole sample
intervals. Various high grade cuts were used for both Li2O and Ta2O5 based on statistical review
of each object.

Li2O and Ta2O5 grades for the main mineralised zones were interpolated using ordinary kriging.
High and low grade domains were estimated independently with hard boundaries assumed between
domains. A two search pass strategy was employed, with successive searches using more relaxed
parameters for selection of input composite data, and a greater search radius. Blocks not informed
for any given variable after two passes were assigned the Sichel Mean of the input data from that
particular domain.

In situ bulk densities for the Bald Hill Mineral Resource have been assigned on a lithological basis
for both mineralisation and waste, based 69 cores samples and values taken from those used in
similar deposits and lithologies. Fixed density values assigned into the block model included waste
back-fill to 1.8t/m3, transitional pegmatite to 2.5t/m3, fresh metasediment waste to 2.74t/m3, fresh
diorite dykes to 2.8t/m3 and fresh pegmatite to 2.65t/m3. Additional bulk density analysis is being
undertaken utilising DD core.

The resource model was validated both visually and statistically prior to final reporting.

Cut-off Grades

The Bald Hill MRE pegmatite wireframes were generated using logged pegmatite lithologies and
a minimum down hole width of 3m, while the internal ‘high grade’ lithium wireframes were
generated using a nominal 7,500ppm cut-off grade and a minimum down hole width of 3m
determined from exploratory data analysis as a point of inflection within the Li2O grade
distribution.

The Mineral Resource is reported using a 0.5% Li2O cut-off which approximates a conservative
cut-off grade used for potential open pit mining as determined from preliminary pit optimisations.
Mineral Resource Classification

The Mineral Resource has been classified in the Indicated and Inferred categories, taking into
consideration numerous factors including drillholes spacing, estimation quality statistics (kriging
slope of regression), number of informing samples, average distance to informing samples in
comparison to the semivariogram model ranges, and overall coherence and continuity of the
modelled mineralisation wireframes.

Eventual Economic Extraction

The Bald Hill pegmatite deposit has previously been mined for tantalum (Ta2O5), however no
account for Li2O was undertaken. A positive conceptual engineering study (refer Tawana ASX
release 16th January, 2017) undertaken by Tawana reported that the deposit could be mined
economically via open pit methods. Tawana subsequently announced the commencement of a full
feasibility study for the Bald Hill Lithium and Tantalum Project and has commenced early stage
earth works on site, with first production expected in the first quarter of 2018.

Independent Qualified Person’s Report by AMA

AMA will issue an independent qualified person’s report which complies with the requirements
as set out in paragraph 5 of Practice Note 4C of the Listing Manual Section B: Rules of the Catalist
of the Singapore Exchange Trading Limited (“Catalist Rules”) in due course.
Bald Hill Project (AMA 100%, TAW Earning 50%)

The Bald Hill project (Project) area is located 50km south east of Kambalda in the Eastern
Goldfields of Western Australia. It is located approximately 75km south east of the Mt Marion
Lithium project and is adjacent to Tawana’s Cowan Lithium project. The Project, owned by
Alliance Mineral Assets Limited (AMA), includes a permitted tantalum (pegmatite) mine,
processing facility and associated infrastructure.

Through Tawana’s 100% owned subsidiary Lithco No. 2 Pty Ltd (Lithco), Tawana entered into a
Farm-In Agreement on 23 February 2017 with Alliance Mineral Assets Limited with respect to
AMA’s Bald Hill project in Western Australia for the purpose of joint exploration and exploitation
of lithium and other minerals.

The commercial terms require Tawana:

   i. to spend, by 31 December 2017 (or such later date as may be agreed between the parties),
      a minimum of $7.5 million on exploration, evaluation and feasibility (“Expenditure
      Commitment”); and at its election

   ii. to spend, $12.5 million in capital expenditure required for upgrading and converting the
       plant for processing ore derived from the Project, infrastructure costs, pre-stripping
       activities and other expenditures including operating costs (“Capital Expenditure”) by 31
       December 2019.

Upon completion of the Expenditure Commitment, Tawana shall be entitled to 50% of all rights
to lithium minerals from the tenements comprising the Project (“Tenements”). AMA and Lithco
had on 10 April 2017 entered into a lithium rights joint venture agreement.
Upon completion of the Expenditure Commitment and Capital Expenditure, Tawana will be
entitled to a 50% interest in the Project (being all minerals from the tenements and the processing
plant and infrastructure at Bald Hill). The portfolio of mineral tenements, comprising mining
leases, exploration licences, prospecting licences, miscellaneous licences, a general-purpose lease,
and a retention lease are in good standing. AMA and Lithco had on 18 April 2017 entered into a
Bald Hill Joint Venture Agreement.
