Mac Copper Limited
A copper mining company that owned and ran the CSA copper mine, one of Australia's highest-grade underground copper mines, near Cobar in New South Wales. Founded in 2022 as Metals Acquisition Limited, it renamed itself MAC Copper Limited in 2024 to reflect its focus, and was later acquired by Harmony Gold. The mine's "CSA" name comes from the Cornish, Scottish, and Australian backers of the original syndicate that financed it after copper was discovered there in 1871.
