The Retail Offer will not be completed without the Placing also being completed.

Proceeds from the Fundraise will allow Atalaya to accelerate the development of its copper growth projects in Spain in order to capitalise on strong copper market fundamentals. The Fundraise will also provide the Company with financial flexibility to optimise the ultimate funding package for Proyecto Touro all while to advance its growth pipeline in the Riotinto District in parallel.

Reason for the Retail Offer
