The Joint Venture of the Tin International AG and Lithium Australia NL (ASX: LIT) has commenced a diamond drilling program at the Sadisdorf project. Lithium Australia, a Perth-based company, has the right to earn up to 50 % of the Sadisdorf project by spending a total of 2 million € on exploration. The drilling program consists of two core holes with a total length of 460 m and aims to provide additional validation of the historical exploration work in order to increase the confidence level of future mineral resource estimates towards the “indicated” status and has the potential for further resource inventory growth. It will also generate core samples for further metallurgical test work. The drilling campaign follows last week’s announcement of a first lithium resource estimate according to the internationally approved JORC (2012) Code for the Sadisdorf project, which comprises mineral resources of 25 million tons grading 0.45 % Li2O (cutoff: 0.3 % Li2O) of the “inferred” category.
