Global Lithium Resources Ltd (ASX:GL1) has revealed further high-grade lithium results from its ongoing 50,000-metre drilling program at the company’s Manna Lithium Project in Western Australia.
To date, the company has completed over 25,000 metres of drilling at the project with the majority of the assays pending,
Four reverse circulation rigs and one diamond drill rig are currently onsite performing resource expansion, infill and geotechnical drilling.
The current drilling program is expected to be complete by early December 2023 with final assays to be received in the March quarter of 2024.
Returning “excellent grades”
Global exploration manager Logan Barber said: “The significant 2023 Manna drilling program is progressing well while being executed safely by a great team.
“Initial results are very pleasing with the LCT pegmatite system still open in multiple directions and the infill results we have received to date returning excellent grades.
“We are on track to deliver approximately 50,000 metres of extensional and infill drilling by early December, as we continue to progress key items related to the DFS including the geotechnical drilling and water exploration programs.”
Drill program
Two RC rigs have been deployed to infill drill the existing Manna resource model to a 40 metre by 40 metre grid which will increase confidence in the resource model and allow for more accurate mine scheduling to be used in the final DFS.
A grid of 10 by 10 metres drill spacing will also be tested to provide grade variability data. This information will help define the ideal drill spacing required to move a portion of the main resource into a measured category.
Additional geotechnical and hydrological drilling is underway to complement the definitive feasibility study (DFS), which is running in parallel with the Manna Lithium Project drilling program.
Forward plan
A further two RC rigs and one diamond drill rig are tasked to expand the current resource along strike and at depth.
These results will be used in the fourth update of the mineral resource estimate (MRE) for the Manna deposit, which is expected to be released in the June quarter of 2024.
Due to the success of the current program, further step-out drilling and testing of target areas away from the main Manna resource will be planned for the first half of 2024.
