scottpev, as far as I understand the dispute is related to the amount of sulphide ores. The transitional ore mined problematic in the early stages which I believe led to EXS giving Copperchem 90 day terms.

Since they are only producing with a sulphide circuit it is hard to understand that there can be a material difference between the royalties being claimed by either side.

Output of copper is directly related to this circuit so it seems to me this dispute is just a bargaining chip.
