BLM "public mining claims"? Options

[CP]

In a recent thread on the CP club's facebook group page it was stated that the BLM holds "public mining claims"......
I don't think this to be true but I thought we could use more input from our very informative CP forum users to offer on the question.
So I thought we'd pose this question here......Has anyone heard of any "public mining claims" (actual claims/names or #'s) held directly by the BLM?
What are your thoughts on this at the CP forum folks?

I believe the person is simply misunderstanding/using the word "claim" with what should be "area" instead.
