Rio Tinto Group (ASX:RIO) chief executive Jakob Stausholm said the firm said it is "increasingly convinced of sufficient investor demand" for a strategic placement as it considers raising capital via the issuance of new shares, The Australian Financial Review reported Monday.

Stausholm said no final decision had been reached, according to the report.

The issuance could improve Rio Tinto's liquidity, and relieve tensions within its dual London Stock Exchange-Australian Securities Exchange share structure.

About 77% of the mining giant's shares are listed on the London Stock Exchange while 23% are on the ASX.

The firm is more likely to issue shares in the Australian company, Rio Tinto, the report noted.
