Leasing mineral rights through an estate that is in probate and has been for almost 3 years

My sister is representative, and there is 3 of us kids. My mother had 3 different mineral locations. My sister wants the minerals to stay in the family while us other two and willing and ready to sell our portions. She just signed a lease thru the estate. What does that mean as far as a timeline and the capability of ever closing the estate so it can be distributed?
