Leasing Companiees

Hello, I’m new to all of this.

I was wondering if anyone had heard of Rockwell Energy LLC?

Are they a valid company (I’m unable to find any information on them - no website), a true middleman or a 3rd party trying to upsell a lease of a mineral right?

I don’t have any other offers for leasing and they give a deadline coming up and I don’t know what to do.

Thank you for all of your generous input!
