Australia's Mineral Resources said on Tuesday that it has bought additional shares in lithium miner Azure Minerals AZS.AX, raising its stake to 13.56% from 12.23% previously.
Mineral Resources is currently on a stake-buying spree, with the lithium miner recently acquiring about 19.9% in Wildcat Resources to become a substantial shareholder.
Previously, Hancock Prospecting, owned by Gina Rinehart, Australia's richest person, accumulated an 18.3% stake in Azure, which threatened to topple a A$1.63-billion buyout deal by Chile's SQM for the company.
SQM, Azure Minerals, and Mineral Resources did not immediately respond to a Reuters request for a comment.
