ASX-listed Botswana Metals has lodged three extension applications with the Botswana Department of Mines (DoM) for prospecting licences at its Maibele North nickel project. Maibele North, which has a reserve of 2.38-million resource tonnes, was being developed through a joint venture (JV) with Botswana government-owned mining and smelting company BCL Limited. This partnership was now seeking to increase its resource tonnes, with a prefeasibility study (PFS) by project delivery firm WorleyParsons currently under way.
