Kalahari Key owns the Molopo Farms Complex project in south-west Botswana, known to be highly prospective for nickel and platinum group metals.
The total consideration is US$194,810, to be settled out of existing cash resources.
In addition, ABM may elect to earn-in to a 40% direct project interest in the MFC roject by expending US$500,000 by 31 December 2020 on ground exploration, expected to include drilling of high priority targets.
Upon completion of the earn-in expenditure requirement, ABM will hold a total economic interest of 50.96% in the MFC project through its 18.26% shareholding in Kalahari Key and 40% direct interest in the MFC project.
The MFC Project comprises three exploration licences, covering 2,725 square kilometres which are believed to be prospective for nickel, PGM and copper mineralisation.
Kalahari Key has recently undertaken a high-resolution, helicopter-borne electromagnetic and magnetic survey, which identified 17 key zones where the conductivity of the rocks is of interest.
"I am delighted to secure this new Botswana opportunity for African Battery Metal shareholders,” said chairman Andrew Bell.
"Botswana is an exceptional country with exciting exploration opportunities and a superb operating environment."
