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 following link: http://www.rns-pdf.londonstockexchange.com/rns/0252Z_1-2019-5-14.pdf
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."

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.
