Florida Mineral Rights

I live in Florida & just found out my grandfather left me mineral rights. This is a big surprise finding out after 40 plus years. I’m from Austin & Ft Worth, and know nothing about what this means. Beginning this month received letter RE: Oil & Gas Lease for Section 270, Block 13, H&GN Survey, Reeves County, Texas. It states that according to a title research I’m the owner of an “undivided 0.833334 net mineral acres under the above described land”. Does anyone know this area and what this means to me???

Hey Pepper. I know the area pretty well. It sounds like they are wanting to lease the acreage you own.
