Commencement of Drilling & Exploration Update

ewoyaa lithium project, ghana west africa 

Atlantic Lithium Limited (AIM: ALL, OTC: ALLIF, "Atlantic Lithium" or the "Company"), the fully funded, African- focussed lithium exploration and development company on track to become West Africa's first lithium mine, is pleased to announce commencement of drilling at the Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa where it has defined a JORC compliant Mineral Resource Estimate ("MRE") of 21.3Mt @1.31% Li2O.

Figures and Tables referred to in this release can be viewed in the PDF version available via this link:http://www.rns-pdf.londonstockexchange.com/rns/1082F_1-2022-3-17.pdfHIGHLIGHTS:

Ø Reverse circulation ("RC") drill rig arrived on site and commenced drilling.

Ø Approximately 12,000m of exploration, 6,000m of resource extension and 960m of geotechnical drilling planned.

Ø Exploration RC drilling designed to test several new targets defined in auger drilling within the Ewoyaa pegmatite corridor, to the north and south of the current MRE.

Ø Resource extension RC drilling designed to test depth and strike extensions of known mineralisation.

Ø Geotechnical diamond core ("DD") drilling designed to test proposed mine pit wall ground conditions for detailed engineering design.

Ø Airborne geophysical survey contract awarded to NRG for regional magnetics and radiometrics survey over the Cape Coast license.

Ø Regional exploration auger drilling ongoing over Mankessim and Saltpond licenses, and 100m x 100m soil survey commenced over the Cape Coast license.

Ø Recently announced Scoping Study update (refer RNS of 7 December 2021) delivers exceptional financial outcomes for a 2Mtpa operation, producing an average c. 300,000tpa of 6% Li2O spodumene concentrate ("SC6") over an 11.4-year operation:

o Life of mine ("LOM") revenues exceeding US$3.43bn, Post-tax NPV8 of US$789m, IRR of 194% over 11.4 years

o US$70m capital cost with industry-leading payback period of

o C1 cash operating costs of US$249 per tonne of 6% lithium spodumene concentrate Free on Board ("FOB") Ghana Port, after by-product credits

o Pre-tax NPV8 of US$1.23bn and EBITDA of US$2.02bn for LOM

o Average EBITDA of US$178m per annum

Ø Significant potential for resource upgrades to extend the planned LOM; Project metrics substantially improve with an LOM beyond 12 years.

Commenting on the Company's latest progress, Len Kolff, COO of Atlantic Lithium, said:

"We are pleased to have Geodrill back on site to commence the 2022 drilling season; field teams have done a great job to open access and prepare drill pads ahead of the drill rig's arrival.

"Since commencing exploration earlier this year, we have identified six new target areas for RC drill testing; all within 3.5km of the current 21.3Mt @1.31% Li2O resource footprint. We have also identified extensions within the current MRE, where mineralisation remains open along strike and at depth for RC drill testing.

"To date, only a small area of approximately 28km2 has been auger tested, with an even smaller 13km2 area drill tested within our broader 560km2 lithium portfolio in Ghana.

"The exploration potential is clear, and we see significant resource growth potential. Not only do we believe that Project metrics will improve significantly beyond the current defined mine life, but we also see further potential for economic improvement due to the recent increases in spodumene concentrate pricing which have far exceeded our initial SC6 price modelling parameters.

"These fundamentals continue to demonstrate Ewoyaa as an industry-leading asset; with the Company ideally positioned to benefit from the growing lithium demand."

Drilling Commenced

Drilling has commenced on site with a Sandvik DE 810 multipurpose RC drill rig collaring the first hole of the 2022 drilling season (refer Figure 1).

The planned programme consists of approximately 19,000m of drilling including exploration and resource extension RC drilling and geotechnical DD drilling.

Ongoing exploration auger drilling, in conjunction with our regional soils geochemistry data sets, has defined six high-priority pegmatite target corridors for drill testing. All exploration targets are within 3.5km of the current Ewoyaa MRE (refer Figure 2).

To date approximately 28km2 has been auger drill tested with 160m, 80m and 40m line spacing and 20m to 10m collar spacing, with only 13km2 drill tested within our broader 560km2 portfolio in Ghana.

Regional auger drilling will continue in parallel with the RC drilling programme to test exploration targets within the Saltpond license and continue to define targets within the immediate MRE area in the Mankessim license.

The Company has engaged NRG South Africa for the regional airborne geophysical survey over the recently granted Cape Coast license. Field teams have commenced a 100m x 100m grid soil geochemistry survey to complement the regional geophysics and geochemistry data sets over the adjacent licenses for future targeting (refer RNS of 19 November 2021).
