Acrux

The third- and fourth-most common subvariants, respectively, are XBB.2.3, which some have nicknamed Acrux; and XBB.1.5, also known as Kraken.

Another question mark is the future of Acrux, the investment vehicle Codelco formed to allow its potential purchase of a stake in the Sur properties.

This depends on whether the assets become part of Codelco or Acrux, the investment vehicle it formed to buy part of AAS.

Should Acrux exercise its put option and sell half of its stake to Mitsui, the companies have drafted a shareholder pact.

Codelco would participate in the transaction through its investment subsidiary Inversiones Mineras Acrux SA.
