Core Asset Comparison

Feb 5 (Reuters) - Rio Tinto walked away from a mega-mining deal with rival Glencore for the third time on Thursday.

Attempts to combine the companies have repeatedly fallen short. Rio rejected a merger approach from Glencore in 2014, saying it was not in the best interests of shareholders, and another round of discussions in 2024 also fizzled out without a deal.

Had the two companies joined forces, their combined operations would have created a behemoth valued at nearly $207 billion.
