They have no PM hedges anymore (as of a few yrs ago).
They partially hedge their lead and zinc production, which early on cost us money, but lately has saved us money. Probably a wash to date, but going forward, probably to our advantage overall, for a while.
No, there are no hedges for Gold and Silver. They do hedge some of the byproduct metals tin and sync to keep costs stable.
I actually would not want them to have any hedges. They have enough cash to survive the downturn. If it gets too bad, shut down the mines, but no hedges. Hedges only enrich bankers.
