Preliminary Metallurgical Test Work Confirms High Quality
Lithium Concentrate
Savannah Resources plc (AIM: SAV) ('Savannah' or 'the Company'),
the AIM quoted resource development company, is pleased to announce
that preliminary metallurgical test work on a composite lithium
sample from the Mina do Barroso project in northern Portugal
confirms that a very pure low iron spodumene concentrate can be
produced. Savannah has a 75% interest in Slipstream Resources
Portugal Unipessol Lda, which is the registered holder of the Mina
do Barroso mining licence. To view the press release with the

HIGHLIGHTS:
-- Metallurgical test work undertaken on a composite sample from
Mina do Barroso to determine if lithium bearing minerals can be
recovered using commercially available technology to produce a
saleable product;
-- Work confirms that a high-grade, very pure, low iron spodumene concentrate can be produced;
-- Single analysis of the combined sample confirmed a high Li O
head grade (1.95% Li O) and low Fe O head grade (0.9%);
-- Heavy Liquid Separation ('HLS') shows a very pure (8%) Li O product can be produced;
-- Floatation results utilising a simple one stage float without
any optimisation achieved 83.7% Li O recovery at 5.9% Li O, this is
very positive and can be improved through optimisation;
-- Microscopy confirmed that the concentrate was almost entirely
spodumene with only very minor amounts of petalite;
-- Test work confirms that a high quality spodumene concentrate
can be produced using conventional commercially available
processing technologies; and
-- 3,000-5,000m drill programme to commence shortly, focusing on
defining a JORC mineral resource estimate to support potential mine
development.
Savannah's CEO, David Archer said: "We are delighted with these
results as they confirm that a high-grade, low impurity spodumene
concentrate can be produced using conventional, well understood
processing techniques. Furthermore, based on the quality of the
results, we believe that our spodumene concentrate is likely to be
highly sought after by manufacturers of battery grade lithium.
"Whilst it is still early days, we are working to highlight what
we believe to be the superior characteristics of our Portuguese
lithium project, namely:
-- Spodumene dominant mineralisation;
-- Granted Mining Leases;
-- Conventional and well understood processing techniques;
-- High-grade, low impurity spodumene concentrates;
-- Extensive lithium mineralisation over at least 6km; and
-- Excellent regional lithium exploration potential from extensive pegmatite fields.
"All of this is within a premier mining jurisdiction with a
government intent on supporting the development of a lithium
industry in Portugal. Accordingly, we are highly encouraged with
the results received to date and will be moving forward with
drilling shortly as we look to define a JORC mineral resource
estimate."

Technical Data
The scope of work was to conduct preliminary ore
characterisation test work on a composite sample from the NOA and
Reservatorio Deposits (sample site 3, 10, 11, 12 on Figure 1) on
the Mina do Barroso mining lease to determine if the lithium
bearing minerals could be recovered from the rock using
commercially available technology and a saleable product produced.
The work was conducted by lithium specialists Nagrom Metallurgical
in Perth, Australia.
The test work is outlined as follows:
-- Sample analysis by x-ray fluorescence ('XRF') and inductively
coupled plasma ('ICP') to determine lithium grade of the sample and
any potential penalty elements;
-- Size analysis to determine what size fraction contains the lithium minerals
-- Microscopy for mineral identification;
-- Heavy Liquid Separation at SG 2.7 to determine if gravity
separation can recover the lithium minerals; and
-- Single stage floatation test to determine if lithium minerals can be recovered via flotation.
Results
Location data and individual analysis of the samples taken and
combined into the preliminary metallurgical test sample is provided
below and confirmed the rocks were lithium bearing.

About Savannah
Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented,
multi-commodity, mineral development company.
Mozambique
Savannah operates the Mutamba heavy mineral sands project in
Mozambique in collaboration with Rio Tinto, and can earn a 51%
interest in the related Consortium, which has an established
initial Indicated and Inferred Mineral Resource Estimate of 4.4
billion tonnes at 3.9% THM over the Jangamo, Dongane and Ravene
deposits. Under the terms of the Consortium Agreement with Rio
Tinto, upon delivery by Savannah of the following will earn the
corresponding interest in the Mutamba Project (which currently is
20% following delivery of scoping study in May 2017):
pre-feasibility study - 35%; feasibility study - 51%. Additionally,
the Consortium Agreement includes an offtake agreement on
commercial terms for the sale of 100% of heavy mineral concentrate
production to Rio Tinto (or an affiliate).
Oman
Savannah has interests in two copper blocks in the highly
prospective Semail Ophiolite Belt in Oman. The projects, which have
an Indicated and Inferred Mineral Resource of 1.7Mt @ 2.2% copper
and high-grade intercepts of up to 56.35m at 6.21% Cu, with gold
credits, provide Savannah with an excellent opportunity to
potentially evolve into a mid-tier copper and gold producer in a
relatively short time frame. Together with its Omani partners,
Savannah aims to outline further mineral resources to provide the
critical mass for a central operating plant to develop the deposits
and in December 2015 outlined exploration targets of between
10,700,000 and 29,250,000 tonnes grading between 1.4% and 2.4%
copper.
Portugal
Savannah holds a 75% interest one mining licence and nine
prospective applications for the exploration and development of
lithium, covering an area in excess of 1,018km2 in northern
Portugal. This includes the highly strategic Mina do Barroso
prospect, which with an approved Mining Plan ('MP'), Environmental
Impact Assessment ('EIA') and a 30-year mining concession/Mining
Licence ('ML'), means that with a defined JORC resource a
development decision could be made as early as Q4 2018.
Finland
Savannah has Reservation Permits over two lithium projects,
covering an area of 159km(2). Geological mapping has highlighted
the presence of seven pegmatites with key lithium minerals
petalite, spodumene and lepidolite all identified.
