High grade depth extensions at the Bougouni Lithium Project
-
Diamond drilling at Goulamina Main Zone extends high grade lithium mineralisation beyond 150m down dip and confirms up-dip continuity;
33m @ 1.74 % Li2O from 103m including 12m @ 2.17 % Li2O
33m @ 1.74 % Li2O from 139m including 10m @ 2.08 % Li2O
49m @ 1.64 % Li2O from 40m
40m @ 1.50 % Li2O from 27m
28m @ 1.77 % Li2O from 43m
-
53m @ 1.69 % Li2O from 60m (extended hole)
-
Diamond drilling results pending for additional pegmatite intersections at West Zone
-
Independent Mining Consultants engaged for next phase of resource evaluation and project studies
-
Maiden JORC-compliant resource expected in October
Birimian Limited (ASX:BGS; "Birimian" and "Company") is pleased to announce further high-grade results from its maiden drilling program at its 100%-owned Bougouni Lithium Project ("Project") in southern Mali.
The Project comprises a large license area spanning some 250 km2, and hosts the high-grade, potential bulk-tonnage Goulamina lithium deposit.
Further promising results have now been received for eight (8) Diamond drill (DD) holes targeting extensions of the Goulamina Main Zone (Figure 1). Substantial intersections continue to define high-grade lithium beyond 150m down dip, and confirm robust continuity in the up-dip portions of the deposit.

Diamond Drilling Extensions
Results from Diamond holes drilled at the Main Zone (Figure 1 and Table1) define high grade extensions to depth along the length of the Goulamina deposit. Results include;
33m @ 1.74 % Li2O from 103m including 12m @ 2.17 % Li2O
33m @ 1.74 % Li2O from 139m including 10m @ 2.08 % Li2O
53m @ 1.69 % Li2O from 60m
Extension to previously reported drill hole GMRC012
15m @ 1.73 % Li2O from 132m and 19m @ 1.58 % Li2O from 150m
In addition, shallower up-dip holes (GMDD001 - 003) were drilled to provide material for upcoming metallurgical test work. As expected, these holes confirm excellent continuity of mineralisation in the central portion of the Main Zone. Results include;
49m @ 1.64 % Li2O from 40m
40m @ 1.50 % Li2O from 27m
28m @ 1.77 % Li2O from 43m
Detailed drilling at Main Zone has defined shallow, continuous, high grade lithium mineralisation over approximately 700 metre of strike, and beyond 150m down dip (see Figures 1 and 2). Drill holes into the recent West Zone discovery have confirmed wide and high grade lithium mineralisation over approximately 300m of strike, with significant scope for extensions along trend.
Results are also pending for a further five (5) Diamond holes evaluating along strike and down dip from the exciting new West Zone discovery. Birimian believes there is excellent potential to add significant tonnages of high grade mineralisation with more drilling here.
Exciting Next Steps
Resource and Scoping
A total 50 holes for 5,179m of drilling have now been completed at the Main and West Zones. This first phase work program provides the geological and grade data required to estimate the maiden resource at Goulamina. Birimian has engaged Cube Consulting and CSA Global to undertake an independent resource estimation and preliminary economic mining study for the Project. Data compilation and validation is progressing well, with the maiden JORC-compliant resource expected in October.
Mineralisation is open along strike and to depth outside the present limits of drill coverage. Further drilling is planned to investigate extensions to mineralisation during the next phase infill and step-out drilling program. To facilitate completion of core processing and inclusion of all relevant data in the
pending resource estimation, drilling has paused briefly and is expected to re-commencement in November when scoping work has been substantially completed.
