The concession comes just over a year after President Emmerson Mnangagwa's government signed an agreement with Cyprus-based Karo Resources to develop a $4.2 billion integrated platinum mine.
Zimbabwe is seeking to quickly exploit its reserves of platinum, which is used in catalytic converters for limiting emissions at a time vehicle manufacturers are moving to electric cars powered by lithium batteries.
The information ministry said Bavura Holdings, in which Nigerian billionaire Benedict Peters is a major shareholder, would on Thursday sign an agreement to mine platinum on Zimbabwe's mineral-rich Greak Dyke. It did not give details.
Peters, who is based in Ghana, is the founder of Aiteo Group, which has interests in oil.
Mines Minister Winston Chitando said last month the government would name two new investors to develop separate platinum mining projects west of the capital.
Anglo Platinum and Impala Platinum Holdings already mine platinum in Zimbabwe. Impala also owns a joint-venture mine with Sibanye-Stillwater.
A Russian consortium and Zimbabwean investors are developing a platinum project in Darwendale near Harare.
