ABSTRACT:Birimian Limited (ASX:BGS; Birimian or the Company) is pleased to announce a further substantial upgrade to the Mineral Resource estimate for the Company’s Goulamina Lithium Project (Goulamina or the Project) in southern Mali. In late April 2018, the Company announced a revised Mineral Resource of 65Mt @ 1.43% Li2O (BGS; 27 April 2018), doubling the previously reported Mineral Resource. The Company reported that drilling was ongoing at the Yando and Danaya pegmatites and that a further update of the Goulamina Mineral Resource would be provided once this work was completed. Drilling has revealed that the Yando and Danaya zones are continuous. As a result, the Yando and Danaya pegmatite zones henceforth will be referred to simply as Danaya. Cube Consulting Pty Ltd (Cube) prepared the updated Mineral Resource and has advised that Danaya contains an estimated Inferred Mineral Resource of 38.2Mt, grading 1.14% Li2O. The combined Indicated and Inferred Mineral Resource at Goulamina is now 103.2Mt @ 1.34% Li2O, with a contained lithium content of 1.39Mt (up from the previous 931kt), with the inclusion of the Danaya Mineral Resource (see Table 1) The resource definition drilling of the Danaya pegmatites was conducted on sections spaced 100m apart, with holes spaced at 50m intervals along the drill lines. A total of 99 reverse circulation (RC) holes, for 11,274m, has been completed, plus three diamond holes with RC pre-collars for a further 390m. The drill hole locations and some of the lithium assay intersections from this work are reported in ASX announcements dated 21 November 2017 ("Goulamina Drilling Progress Report") and 11 April 2018 ("Further Successful Drilling Results"). The balance of the holes and all assays now received are included in Appendix 1, Tables 1 and 2.
