RNS: Drill results confirm resource expansion potential Savannah Resources plc ('Savannah' or the 'Company'), the resource development company, is pleased to announce further results from the first phase of the current two stage DFS drilling programme at the Barroso Lithium Project ('the Project') located in northern Portugal (Figure 1). The Project, currently with a 28Mt @ 1.05% Li2O Mineral Resource, is Europe's most significant spodumene lithium deposit.
Highlights:
· Savannah reports significant lithium assays which it has received from a further 8 diamond drill holes (4 at Pinheiro, 3 at NOA, 1 at Reservatrio) undertaken for geotechnical, metallurgical, and resource purposes as part of the Phase 1 DFS drill programme.
· At Pinheiro, where 2 pegmatite bodies (the Eastern and the Western), have been previously identified, the results from metallurgical and resource diamond drilling, have confirmed the tenure of lithium mineralisation from Reverse Circulation ('RC') drilling (see 12 March RNS) and highlight the potential for the expansion of the resource.
· Significant lithium mineralisation intersections at the Western pegmatite at Pinheiro include:
o 36.5m @ 1.24% Li2O from 33.5m in 24PNRDD003
o 16.48m @ 1.22% Li2O from 41.02m in 24PNRDD004
o 14.08m @ 1.04% Li2O from 9.32m in 24PNRDD007
o 16.43m @ 1.57% Li2O from 18.57m and 11m @ 0.79% Li2O from 61m in 24PNRDD008 (vertical hole not true widths)
· The diamond holes at Pinheiro also show that mineralisation continues to the north on the Western Pegmatite, outlining the greater resource potential, to be tested in the second phase of drilling.
· At NOA two metallurgical holes that twinned previous RC drilling and a geotechnical hole confirm the continuity of lithium mineralisation.
· Significant lithium mineralisation intersections at NOA include:
o 9.86m @ 1.3% Li2O from 49.14m in 24NOADD011 (twinned holes)
o 5.45m @ 1.25% Li2O from 0.35m in 24NOADD010 (twinned holes)
and 21m @ 1.26% Li2O from 31m
· At Reservatrio a diamond hole drilled for geotechnical purposes intersected 53.1m of pegmatite and aplite and shows that the Reservatrio pegmatite continues to be mineralised at depth.
· Significant lithium mineralised intersections at Reservatrio include:
o 7m @ 1.16% Li2O from 143m, 5.7m @ 0.81% Li2O from 172m and 6.5m @ 1.22% Li2O from 180.5m in 24RESDD013
· Note that the geotechnical holes were designed to gain structural information about the designed pit walls and the pegmatite intercepts were incidental to that.
· Next steps: Once the remaining phase 1 assays have been received, analysed and any further significant assays reported, planning for phase 2 of the programme can then be completed.
