ASX-listed Birimian has delineated two additional pegmatite anomalies at its Goulamina lithium project in southern Mali – a highly positive development for the company.
Mali– Birimian received all analytical data for the combined exploration and sterilisation programme carried out between October 2017 and April 2018.
Results of auger programme
The Sabali exploration zone is at least 1km long, as identified by several auger lines 2 km SSE of Sangar II. The completed dataset relates to 2 757 auger holes with an average depth of 8.8 m (total 24 232 m). Holes were spaced at 25 to 50m, along lines 600 and 300 m apart.
Several geochemical anomalies have been defined using a threshold of 0.06% lithium oxide. In addition to those already reported, two further anomalies have been outlined to the SW and NE of Sabali. These have been named Dowere (meaning ‘Another’ in the local Bambara language) and Bara (Work).
Based on results of reverse circulationdrilling on the earlier discovered geochemical anomalies (e.g. Yando and Danaya), it is highly probable that these two anomalies represent lithium-bearing pegmatite deposits.
Exploratory drilling to establish pegmatite geometry and grade will be undertaken after the conclusion of the wet season, which usually finishes in October.
“The NW-SE trending structure is now very clearly defined by auger and other drilling. The presence of this structure provides a framework for the discovery of yet more pegmatites to the SW of Bara. The scope of future exploration programmes will be determined following receipt of the upgraded mineral resource estimate expected in mid-2018,” says Birimian executive director and CEO Greg Walker.
