Nickel miner, Allegiance Mining (AGM) wants Zinifex to make its intentions clear about the $745 million hostile offer and whether it will close tonight or be extended.
"We have no intention other than to close the offer tomorrow afternoon," Zinifex said on Thursday, according to a media report.
Allegiance replied that this statement may not legally bind Zinifex to close the offer today.
"Allegiance is concerned that Zinifex will today use the tactic of creating uncertainty about whether or not it will close the offer in an attempt to panic some Allegiance shareholders into accepting its inadequate $1.00 offer for Allegiance shares."
In a statement to the stock exchange, Allegiance invites Zinifex to clarify its intentions and ‘not to use carefully crafted statements in the press in a campaign to create uncertainty amongst Allegiance shareholders'.
It said its data room for third parties had been accessed this week and that due diligence was continuing.
"In light of uncertainty which Zinifex is allowing to subsist as to whether it proposes to allow its offer to close today' it considers the status of third party interest to be information material to Allegiance's shareholders.
Zinifex's $775 million offer for Allegiance Mining is hostile. In the period since it was first made, it has had little support.
Allegiance shares finished flat at $1.05, while Zinifex shares were twelve cents higher at $9.37.
