You are either really close or have it. They should be on the same sch E. You should only have one Sch E but will also have worksheets.
Box 1 rent does create a Sch E page 1 for renting out the right to explore.
Box 2 royalty does create Sch E page 1 for royalty income. The royalty is listed as code 6 for property type on line 1b.
Reference: Instructions for Schedule E (Form 1040)
