Zadar Ventures, a Vancouver-based resource company focused on lithium and uranium, has initiated due diligence on its Ravensthorpe lithium project in Western Australia. Earlier this month Zadar entered into a binding Memorandum of Understanding with Australian company Macarthur Minerals Limited through which Zadar will initially earn into 51 per cent of the Ravensthorpe lithium acreage by spending C$2 million within two years from the grant of the Ravensthorpe exploration licences.
