Is there a motel or hotels nearby the mines?

The closest I believe are in hot springs

Yes, it is called the Village Inn their phone number is 501-922-9600.

There are a lot of Airbnb in the area.

There are small motels in Mt. Ida and Jessieville, but gor a chain you have to go to Hot Springs. There are TONS of campgrounds in the area, from primitive to glamping! There are several other mines in the area, too, but Jim's is the best value for the price!
