You can literally mine lodestone and copper. Ancient people have mined those two things since antiquity. Where do you think it comes from now? Fairies?
Bring a live translation device, and program it with whatever the expected language is. That alone would be magic to them. And you don;t need to go to a copper mine, there were markets for processed copper. Pulling it into wire is just a case of roughly forming it into a cylinder, then pulling that cylinder through successively smaller holes. A local smith could help you with that.

You literally could just go dig some yourself while they’re away and procure it that way.
What do you think copper ore looks like? What tools would you use?
Ancient mining was a punishment, generally a death sentence. It’s hard work often overseen by a slave master.
Copper ore isn’t concentrated copper either a lot of ore goes into a little copper. There’s a reason only the really wealthy had copper items.
Well, in this scenario we’d presumably have our electronic devices with us anyway, so it’s honestly a moot point.
It’s amazing what some people here think would be such a simple task in the ancient world.

And then hope they don’t kill you for being a witch.
