Aldeia Delivers Highest-Grade Lithium Mineralisation to Date
Including 22m @ 2% Li(2) 0
Mina do Barroso Lithium Project, Portugal
HIGHLIGHTS:
-- Reverse Circulation drilling on Aldeia Block A continues to
define zones of a high-grade lithium bearing pegmatite body circa
2km south east of the Grandao deposit
-- Key lithium intersections at Aldeia include:
o 45m at 1.67% Li O from 89m, including 22m at 2.00% in
19ALARC024
o 31.7m at 1.47% Li O from 80m in 19ALARC028 and
o 31.5m at 1.14% Li O from 114m in 19ALARC028
o 17m at 1.48% Li O from 96m in 19ALARC026
o 24m at 1.40% Li O from 117m in 19ALARC026
o 21m at 1.17% Li O from surface in 19ALARC018
-- RC drilling at Grandao also identified additional near
surface extensions to the existing mineralisation:
o 12m at 1.08% Li O from 28m in 19GRARC131
o 6m at 1.70% Li O from 36m in 19GRARC130
-- Mineralised drill intersection recorded in 19ALARC024 is the
highest-grade intersection at Mina do Barroso to date
-- Pegmatite consistently intersected over a strike length of
over 250m and has been traced to a depth of over 120m vertical
below surface, confirming the potential for the presence of a
significant mineralised body
-- Drilling continues on the Aldeia deposit focussed on tracing
the pegmatite body further down dip and along strike to the west -
current strike now 250m
-- Results expected to contribute to a significant increase in
the current Mineral Resource of 23Mt resource at Mina do
Barroso
-- Significant Project milestone with over 30,000m of RC and
diamond drilling completed in less than 21 months
Savannah Resources plc (AIM: SAV, FWB: SAV and SWB: SAV), the
resource development company, is pleased to announce further
high-grade results from the ongoing RC drilling programme at the
Mina do Barroso Lithium Project located in northern Portugal
(Figure 1). The results further underline the life of mine and
resource potential of Mina do Barroso and its position as Western
Europe's most significant new spodumene lithium discovery
strategically positioned to supply the growing European Electric
Vehicle ('EV') and lithium ion battery market. To view the press
release with the illustrative maps and diagrams please use the

Savannah's CEO David Archer said: "These latest results from
Aldeia and Grandao include the highest-grade ever reported at Mino
do Barroso of 22m at 2% Li O, demonstrating that the full scope of
Mina do Barroso's exciting potential is still being realised.
High-grade mineralisation has been identified along strike and at
depth, indicating the potential to further expand the existing
resource of 23.5Mt at 1.02% Li(2) 0, and significantly increase the
potential life of mine."
"Results from recent workflow have continued to solidify Mina do
Barroso's status as Western Europe's most significant new spodumene
lithium discovery positioning Savannah as a key strategic player in
Europe's upstream lithium value chain. I look forward to updating
shareholders further with progress made as we advance the Project
towards development."

and Drilling Completed
Further Information
To date a total of 32 RC and 6 diamond drill holes for 3,632m
have now been drilled on Aldeia Block A, as part of the ongoing RC
and diamond drill programme at the Mina do Barroso Project.
Results from the ongoing RC and diamond drilling at the Aldeia
Quarry prospect continue to return excellent thick, high-grade
intervals of mineralisation. The recent drilling has now defined
the pegmatite to a vertical depth of 120m below surface over a
strike of 250m with thicknesses of 20-30m and the mineralisation
remaining open down dip.
The pegmatite at Aldeia is of a similar nature to the other
lithium pegmatites in the Mina do Barroso region, with coarse
spodumene being seen in the drill core. Samples from the recent
drill core have been submitted for metallurgical testing to
establish appropriate recovery parameters.
Several diamond tails are currently being completed on existing
RC drill holes to test the continuity of the second deeper
pegmatite body which has been recently identified. The recent
results are being incorporated into the geology model in
preparation for an updated Mineral Resource estimate to be
completed in the second quarter.
