I’ve been looking for a movie.

I’ve been looking for a movie i saw a couple times. It was a treasure hunting movie probably set in the 1800s or early 1900s. It has a young girl as the star. It was on netflix at one point in the early 2010s i think cause i used to watch it at night when i couldnt sleep. I was younger so it was appropriate for kids but it doesn’t necessarily have to be a kids movie. please help me find it. I know at some point they go through a cave.
