Grandao Continues to Grow with Further Broad Zones of Lithium
Mineralisation Identified at the Mina do Barroso Lithium Project,
Portugal
Savannah Resources plc (AIM: SAV and SWB: SAV) ('Savannah' or
the 'Company'), the AIM quoted resource development company, is
pleased to announce further results from the ongoing reverse
circulation ('RC') drill programme at the Mina do Barroso Lithium
Project ('Mina do Barroso' or the 'Project') in Portugal (Figure
1). The drill programme continues to return significant
intersections of lithium mineralisation as Savannah aims to
increase the current JORC - 2012 compliant Mineral Resource
Estimate of 3.2 million tonnes at 1.0% Li(2) O containing 32,000t
of Li(2) O, which was defined at the Reservatorio Deposit, one of
three targets currently being evaluated. To view the press release

HIGHLIGHTS:
-- Total of 87 holes for 7,081m drilled to date as part of the
ongoing RC drill programme across three primary targets
-- Broad zones of lithium mineralisation intersected giving
further confidence of significant resource potential of Mina do
Barroso
-- Drill programme is ongoing and has been extended as a result
of the positive results received to date
-- Grandao Deposit - New Mineral Resource Estimate on track for
Q1 2018 to add to current Project resource
o Significant widths of lithium mineralisation identified. Key
results include:
-- 59m at 1.13% Li(2) O from 5m, in 17GRARC31
-- 33m at 1.22% Li(2) O from 40m, in 17GRARC41
-- 31m at 1.07% Li(2) O from 40m, including 24 at 1.31% Li(2) O
in 17GRARC25
-- 32m at 0.89% Li(2) O from 35m, including 17m at 1.29% Li(2) O
in 17GRARC38
o Exploration efforts to be accelerated with a diamond drill rig
to mobilise in second half of February, to test depth extensions of
Grandao mineralisation and begin collecting samples for the next
phase of metallurgical test work
o New high priority targets identified to the north east of
Grandao: Romainho, Campo de Futebol and Peigro Negro will be drill
tested
-- NOA Deposit - drilling of a further six holes has confirmed
the presence of lithium mineralisation over a 200m strike length
together with good down dip extensions of at least 50m. Key results
include:
-- 15m at 0.83% Li(2) O from 5m, including 9m at 1.27% Li(2) O
in 17NOARC06
-- 14m at 0.73% Li(2) O from 19m, including 7m at 1.26% Li(2) O
in 17NOARC10
-- Phase 2 of the metallurgical test work programme underway -
samples taken from Grandao, Reservatorio and NOA being tested with
results expected in Q1 2018
Savannah's CEO, David Archer said: "We are delighted to see the
expanding geometry of Grandao with both near surface and deeper
mineralisation. The Grandao Deposit is shaping up as a major
additional component to the overall global Mineral Resource for the
Mina do Barroso Lithium Project.
"The overall tempo of activities continues to accelerate as the
Project's potential becomes more apparent. We are working to an
aggressive timetable to deliver on a series of major milestones
over coming months, which we believe will highlight the Project's
potential to be a key, up-stream component of the European lithium
valued added chain."

Grandao
A total of 57 drill holes for 4,708m (17GRARC01-57) have been
completed and results for drill holes 17GRARC24 to 42 have now been
received and returned further very encouraging results (Tables 1-2
and Figure 2).
Drilling targeted at intersecting the near surface, shallowly
west dipping pegmatite body has continued to meet with significant
success. Drilling has further expanded the zone of lithium
mineralisation, which now extends to over 400m in length, reaching
up to 300m in width and with anomalous mineralisation recorded 185m
below surface.
Significant drill results targeting the flat lying pegmatite
body are summarised in Table 1.

Further drilling of the newly identified sub-vertical body has

mineralisation identified and this body remains open both along
strike and down dip and is a high priority target for further
drilling. Recently received results are summarised in Table 2.

NOA
Drilling at the NOA deposit now totals 10 holes for 768m
(17NOARC01-10) and results from 5 holes (17NOARC06-10) have been
received. Results have been encouraging with 10m-15m wide zones of
pegmatite being intersected over a strike length of 200m and a down
dip depth of around 50m (Table 4 and Figure 3). Further work is now
required to access the full potential of the deposit.

Ongoing Drill Programme
Based on the new results an additional 16 RC drill holes have
been added to the programme at Grandao, Romainho, Campo de Futebol
and Piero Negro in order to further evaluate the potential of the
wider project area.
In addition, to accelerate exploration, a diamond drill rig will
be mobilised to site for an initial 1,500m drill programme, which
will include sample collection for the phase 3 metallurgical test
work programme, stratigraphic/structural holes and the extension of
six existing RC holes to depth to target the newly identified broad
zone of lithium mineralisation identified at depth below
Grandao.
Metallurgical Test Work
The test work programme to determine the crush size and the
density at which a 6% concentrate can be produced and mass yield,
together with the three fundamental design parameters for
developing a gravity process flow sheet based on the dense medium
(DMS) process, is ongoing. Work is expected to be completed in Q1
2018.
