ABSTRACT:Birimian Limited (ASX:BGS; Birimian and the Company) is pleased to report an updated Mineral Resource estimate for the Goulamina deposit at its Bougouni Lithium Project (Project), in Mali. The Mineral Resource at Goulamina now comprises 32.9 Mt @ 1.37% Li2O (0.4% Li2O cut-off, 451,000t contained Li2O, Table 1). This increases the Mineral Resource estimate by around 15%. It includes an Indicated Resource of 25.3 Mt @ 1.37 % Li2O (347,000t contained Li2O, Table 1) at a cut-off grade of 0.4% Li2O – an increase of 300% from the last reported Indicated Resource. Commenting on the upgraded resource, Birimian Chairman Mr James McKay said, "The Goulamina Lithium Deposit is a globally significant hard rock lithium resource. Particularly pleasing is the increase in the Indicated Resource and the identification of new spodumene-bearing pegmatites.” Cube Consulting Pty Ltd (Cube) was engaged to carry out the updated Mineral Resource estimate for the Goulamina deposit. This estimate includes extensions at West Zone and the Sangar Zone to the south west. Detailed information relating to drill data, grades, quality control, and estimation methodology is documented in Appendix 1. Birimian provided the principal sources of information used by Cube in this Mineral Resource estimate including drilling databases, a topographic surface and mapping information. An additional 62 holes (for 4,910m of additional assay data from predominantly 1m interval samples) have been included in the updated estimate, augmenting the 80 holes which informed the maiden Resource model.
