Atlantic Lithium Limited Provides Exploration Update- Additional Drill Rigs Mobilised to Site Visible Spodumene Observed in New Drilling Ewoyaa Lithium Project Ghana, West Africa
Atlantic Lithium announced the mobilisation of an additional 3 drill rigs, the expansion of the drilling programme and new drilling observations atthe Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa where it has defined a JORC (2012) compliant Mineral Resource Estimate ("MRE") of 30.1Mt @1.26% Li2O. Highlights: ØApproximately 9,166m of reverse circulation ("RC") drilling for 52 holes completed to date with assays pending. Multiple and significant visual spodumene pegmatite drill intercepts observed up to 80m long in RC drill chips; assays pending. ØSecond and third RC drill rigs arrived on site and commenced drilling; a diamond core drilling rig ("DD") is due to arrive on site next week, increasing the total number of drilling rigs on site to four. Original planned drilling programme increased from approximately 19,000m to approximately 37,000m of exploration, resource extension, resource infill and geotechnical drilling. Airborne geophysical survey and 100m x 100m grid soil geochemical survey for 9,145 samples completed over the Cape Coast license; results pending. ØExploration RC drilling designed to test new targets defined in auger drilling within the Ewoyaa pegmatite corridor, to the north and south of the current MRE. ØResource extension and infill RC and DD drilling designed to test depth and strike extensions of known mineralisation, convert Inferred to Indicated Resources and define Measured Resources for the first 1.5 years of mine production. ØGeotechnical DD drilling designed to test proposed mine pit wall ground conditions for detailed engineering design. ØRegional exploration auger drilling ongoing over Mankessim and Saltpond licenses. ØThe Company's intention to deliver a Pre-Feasibility Study ("PFS") during Third Quarter 2022 remains unchanged despite delays in receiving assay results from labs experiencing heightened demand. Additional Rigs Mobilised and Expanded Programme: The drilling fleet has been enhanced with the arrival of an EDM 2000 RC rig and a UDR 300 RC rig on site and a further diamond drill rig arriving over the coming week, bringing the total number of drill rigs to four. To date, a total of 9,166m of drilling in 52 holes has been completed with assays pending. The original planned programme of approximately 19,000m of drilling has been increased to approximately 37,000m of drilling including exploration, resource extension, resource infill for Indicated and Measured Resources and geotechnical DD drilling. The 37,000m of drilling planned includes the 9,166m of drilling completed to date. The current programme consists of approximately 13,000m in 124 collars of exploration drilling, 18,000m in 100 collars of resource expansion and inferred to indicated infill drilling, 5,000m in 60 collars of Indicated to Measured infill drilling for the first 1.5 years of mine life and 1,000m in 6 collars of geotechnical drilling. 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 broader 560km2 portfolio in Ghana. Significant Observed Spodumene Pegmatite Drill Intervals; Assays Pending: Drilling observations to date for the 9,166m completed over the Grasscutter North target and Ewoyaa Main depth extension target within the current MRE has returned multiple visible spodumene pegmatite intervals with assays pending. Multiple steeply stacked pegmatite dykes with true widths between 4m to 17m have been observed at Grasscutter North with assays pending. Resource extension drilling at the Ewoyaa Main deposit has intersected significant pegmatite intervals in excess of 100m and up to 150m down hole with spodumene intervals observed over 80m down hole in multiple holes such as GRC0669 and GRC0670 with assays pending. Drilling was completed below previously reported high-grade intervals in holesGRC0425: 75m @ 1.17% Li2Ofrom 68m,GRC0426: 64m @ 1.28% Li2Ofrom 74m andGRC0428: 66m @ 1.26% Li2Ofrom 41m (refer to RNS of 15 December 2021). Newly completed holes are part of the resource expansion programme and indicate a thickening of the pegmatite at depth in this particular area with drilling ongoing and potential to add significant resource tonnes. 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 had previously engaged NRG South Africa for the regional airborne geophysical survey over the recently granted Cape Coast license and field teams had commenced a 100m x 100m grid soil geochemistry survey to complement the regional data sets over the adjacent licenses for future drill targeting (refer RNS of 17 March 2022). Both surveys have now been completed with a total of 3,762 line kilometres completed for the geophysical survey and 9,145 soil samples collected with results pending and potential target areas to be defined for ongoing exploration and targeting.
