Dingyi to make offer for remaining shares in Elemental Minerals HONG Kong-listed Dingyi Group Investment is poised to make a binding takeover offer for the shares it doesn't already own in Australia-and-Canada-listed Elemental Minerals, a person familiar with the matter said. Elemental's key asset is its 93 per cent-owned Sintoukola potash project on the Republic of Congo coastline. The company requested that trading in its shares be halted pending an update on the potential change of control proposal made by Dingyi.
