They are mainly known as a zinc company but also has copper. Thalanga, a Copper Mine owned by Kagara Limited.
PAN is another possibility. Straits Resources Limited ?
Question really is mine in australia or overseas? Do they have a preference?
I wouldn't have thought that PAN was on their list, being a predominantly nickel miner with only minor amounts of Cu and Co from their Ni mines in the Kimberley and Kambalda regions. Neither does copper seem to figure very high in their exploration/drilling activities at present.
I still reckon that SFR is their best bet and highest priority although it now looks as if it would have to be a hostile takeover with the board of SFR refusing OZL a seat at their table.
