Seven Lithium Bearing Pegmatites Identified on Finland
Projects
Savannah Resources plc (AIM: SAV) ('Savannah' or 'the Company'),
the AIM quoted resource development company, announces that all
results have now been received from reconnaissance rockchip
sampling over its new lithium projects in Finland, Somero and
Erajarvi (Figure 1). The work programme has returned anomalous
lithium mineralisation across both projects, leading to the
discovery of seven lithium bearing pegmatites. To view the press
release with the illustrative maps and diagrams please use the

HIGHLIGHTS:
-- A total of 524 rockchip samples have been collected from the
Somero (244 samples) and Erajarvi (288 samples) licences and
submitted to the laboratory for analysis
-- Results have highlighted seven pegmatites with anomalous
lithium - two on Somero and five on Erajarvi
-- Geological mapping and rock chip sampling has highlighted:
o Somero Project, prospective pegmatites with assays of up to
4.47% lithium oxide ('Li(2) O') at the Torkkamaki Prospect and
mineralisation traced over 150m along strike and remaining open
o Erajarvi Project, prospective pegmatites with assays of up to
1.56% Li(2) O at the Viitaniemi Prospect and mineralisation traced
for over 350m before it was covered by glacial till
-- Key lithium minerals petalite, spodumene and lepidolite were all identified in hand specimens
-- Follow up work to further expand and define the seven
anomalous pegmatites in readiness for drilling is being planned for
Q2 2017 (following winter)
-- Finland is one of the most prospective countries on mainland
Europe for potential lithium discoveries. Both project areas enjoy
excellent access to high quality infrastructure and are located
close to potential final customers
David Archer, Savannah's Chief Executive Officer said today, "We
are extremely pleased that the assaying programme has confirmed at
least seven pegmatites anomalous in lithium with the Torkkomaki and
Viitaniemi pegmatites looking to have potential for scale. Finland
is a lithium focus for a number of companies thanks to its
significant resource potential, excellent mining legislation and
infrastructure endowment, and we believe the results we have
received to date support our recent decision to move into this
prospective region. I look forward to providing further updates on
our exploration programme in the New Year as we continue to prove
up the resource potential of these assets."

ROCK CHIP SAMPLING PROGRAMME
Sampling in glaciated terrains such as Finland presents a series
of unique challenges which at times make it very difficult to get a
representative rock chis samples. Millions of years of glaciation
has meant that most of the outcrop has been rounded making it
virtually impossible to sample with a conventional hammer and
softer minerals such as lithium have been stripped from the surface
of the boulder. When combined, these two factors mean that moderate
levels of anomalism in the rock samples are considered significant
and further follow-up sampling is then required using high powered
drills (Figure 2). This method of sampling tends to be largely used
in follow-up sampling due to the weight of the equipment and the
time taken to obtain a representative sample.

A total of 532 samples were collected and sent for analysis,
with 18 of them were anomalous for lithium above 0.1% Li2O.
Fourteen of the samples were from Erajarvi and four from Somero,
with the highest-grade sample of 4.47% Li2O from a petalite outcrop
at Somero (Tables 1-3).

SOMERO LITHIUM PROJECT
Savannah's Somero Reservation (Figure 3) is located less than
2km south of TSX listed Nortec Minerals' Kietyonmaki and Hirvikalio
lithium deposits, which were drilled by the GTK (Finnish Government
Department). Recent work completed by Savannah focused on obtaining
a representative sample from all the known pegmatites within the
licence. Two of the pegmatites sampled returned anomalous lithium
results with the most significant of these being the Torkkomaki,
which contains massive zones of petalite, with results returning a
high-grade lithium assay result of 4.47% Li(2) O (Figure 3).
Mapping has traced the petalite zone for over 150m which remains
open along strike in both directions.

ERAJARVI LITHIUM PROJECT
The Erajarvi Project (Figure 6) reservation covers a swarm of at
least 61 known pegmatites that have been mapped in the area, and
work focused on sampling as many of these bodies as possible.
Sampling confirmed that five of the bodies returned anomalous
lithium with the Viitaniemi pegmatite returning the best results
with assays as high as 1.56% Li2O. Mapping has traced the body for
at least 350m before it was lost under glacial cover and limited
outcrop confirms that the body is at least 10m in thickness and
open in all directions. The prospectivity of these pegmatites was
confirmed in the recent mapping and sampling program and further
detailed sampling to further define the prospectivity of the
lithium bearing pegmatites.

Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented,
multi-commodity, 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 3.5
billion tonnes at 3.8% THM over the Jangamo and Dongane deposits.
Under the terms of the Consortium Agreement with Rio Tinto,
Savannah must deliver the following to earn corresponding interest
in the Mutamba Project: scoping study - 20%; pre-feasibility study
- 35%; feasibility study - 51%. Additionally, the Consortium
Agreement includes an offtake agreement on commercial terms for the
sale of 100% of 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.
Finland
Savannah has Reservation Permits over two new lithium projects,
Somero and Erajarvi, covering an area of 159km(2) in Finland.
Savannah holds a 100% interest in these projects through its
Finnish subsidiary Finkallio Oy. Geological mapping by the Finnish
Government within the project areas has highlighted the presence of
lithium minerals spodumene, lepidolite and petalite with the
Government also identifying Somero and Erajarvi as one of the most
prospective areas to discover lithium deposits in Finland. Follow
up work to further expand and define seven identified anomalous
pegmatites in readiness for drilling is being planned for the
second quarter of 2017.
