Oz Minerals deal, note what the Chinese could not buy up:

"OZ Minerals has been advised that the Treasurer of the Commonwealth of Australia has today announced that he has approved the proposed acquisition by China Minmetals Non-Ferrous Metals Co. Ltd. (“Minmetals”) of all of the assets of OZ Minerals except for Prominent Hill (and related exploration leases), Martabe (and related exploration leases), certain exploration leases in Thailand and Cambodia and all of OZ Minerals’ listed equity investments (“Sale Assets”).

Prominent Hill

Maybe China Minmetal will look around for another Cooper/Gold mine somewhere else?

Original offer for all of Oz Mineral assets was A$2.6 billion

Then dropped to A$1,750 million without Prominent Hill / Martabe

Martabe was later sold for USD 211 million (AUD 260 m)

So back of the envelope calculation puts a value on Prominent Hill at 2,6 b - 1,75b - 0.26 b = AUD 590 m or USD 481m

So we have gold/silver mine project in development in Indonesia http://www.ozminerals.com/Operations/Mining-Operations/Martabe.html
selling at USD 211 m

and gold/cooper mine in production in Australia
http://www.ozminerals.com/Operations/Mining-Operations/Prominent-Hill.html selling at USD 481m

I know they ar not perfect matches to compare to, but maybe someone more knowledgeable than me can run a comparison from here and try to estimate a price for Didipio ?
