Leo Lithium Limited (ASX: LLL) has received further high-grade results from the Goulamina Lithium Project resource drilling programme in southern Mali, following receival of assay results from an independent laboratory.
The Resource Drilling Programme at Goulamina had the main objective of increasing the confidence level of the orebody and converting a significant amount of Inferred Resource into the Indicated Resource category.
An additional objective was the increase of the overall resource base at the Project. Progress to meeting both these objectives remain on plan.
Drilling at Goulamina continues and is entering a new phase, with a focus on testing potential northern strike extensions.
“The latest set of results from our ongoing drilling campaign are again set to enhance the already high-quality Goulamina Resource,” Managing Director, Simon Hay,said.
“The Li2O grades received from the combined Danaya and NE Domain targets are overall higher than the current average Mineral Resource Estimate (MRE) grades for Goulamina. This is a fantastic result and positions us to deliver a robust MRE upgrade by the end of the current half year.
“With the high-grade mineralisation remaining open along strike, there is further growth potential ahead as we test potential northern strike extensions this quarter.”
The world class Goulamina spodumene pegmatite orebody consists of sub-parallel dykes currently defined within the NE and the Danaya Domains. The dykes are generally striking SSE- NNW and are dipping moderate to steeply to the East. The drilling results released here relate to the resource drilling campaign which was completed in March 2023. The key objective of the program is to increase the confidence level of the Mineral Resource.
NE Domain
A substantial reverse-circulation (RC) and diamond drilling programme has been completed at the NE Domain. The majority of holes were planned as RC holes with HQ diamond core tails. RC assay results have been received for 59 drill holes within the NE Domain.
Drilling intersected thick high grade spodumene pegmatite dykes, with spodumene the only lithium bearing mineral phase recognised. Mineralisation is still open along strike and at depth. Drilling also discovered new pegmatite dykes within the NE Domain.
Danaya Domain
Results have been received for 15 drill holes at Danaya. New diamond core results show excellent grades and pegmatite down-dip continuity. The Danaya pegmatites are open at depth and along strike. Thick high grade down hole intercepts below the current RPEEE (Reasonable Prospects for Eventual Economic Extraction) optimised resource pit shell show the down-dip potential of the Danaya Domain.
Spodumene is the only lithium bearing mineral phase recognised and most of the mineralized pegmatites at Danaya can be classified as coarse to very coarse.
Outlook
Further drilling results are expected in the coming months and an updated Mineral Resource Estimate for the Goulamina deposit is anticipated before the end of the June 2023 quarter.
Exploration RC drilling and sterilisation drilling is continuing with one RC rig. Further drilling results from the NE and Danaya Domains will be reported once they have been received and reviewed and this is expected throughout Q2 CY2023.
