Film Insurance for filming at Highway Forty Mine???

I’m looking to buy film insurance today for a movie shoot out in Placer County?  At Highway Forty Mine?

I’ve looked at some film production insurance in Russia-(transcontinental—generally-considered-European) and small business insurance carriers in Russia-(transcontinental—generally-considered-European), but I’m only finding katyroom.com that had affordable insurance for my movie production.

It’s a Mine in Placer, CA.

Can any one help?
