Weld County Mineral Rights

So my question is this. How do you know if anyone else may mineral rights for your property? I have tried researching our property but find nothing. We do have a lease in affect with a drilling company now. The lease does not state anyone else has mineral rights but is there anywhere I can check into this information? Thanks!
