The ASX advanced only marginally at market open on Monday (7 October), but lithium was a big standout after Rio Tinto (ASX:RIO) confirmed it has indeed tabled an offer for $4.46 billion miner Arcadium Lithium (ASX:LTM).
The S&P/ASX 200 rose just 3 points, or 0.04%, to 8,153 points at 10:34am AEDT.

Materials advanced 0.67% led by Arcadium, which spiked 47.61%, after Rio Tinto responded to media speculation that it was pursuing the lithium producer.
The mining heavyweight “confirmed that it has made an approach to Arcadium Lithium regarding a potential acquisition of Arcadium Lithium by Rio Tinto”.
“The approach is non-binding and there is no certainty that any transaction will be agreed to or will proceed.”
