A subsidiary of JSE-listed Union Atlantic Minerals (UAM), formerly Miranda Mineral Holdings, has secured an earn-in option to acquire all of the shares in Renosterkop Mining, a company that holds a prospecting right for tin, zinc and tungsten over certain properties located near Augrabies, in the Northern Cape. AUM says the brownfield Renosterkop project is located in the same geographical location as its Rozynenbosch project, and the agreement presents an opportunity for UAM to earn into a large, shallow tin/tungsten/zinc deposit in the Namaqualand Metamorphic complex.
