What are Campbell County mineral rights worth?
Campbell County sits in the Powder River Basin Niobrara play and is one of the most heavily drilled counties in the state. Producing interests are valued on the standard income multiple, roughly 36 to 72 times your average monthly royalty check, and value moves with both oil and gas prices. Because the county is so heavily drilled, owners here field a high volume of unsolicited offers, which makes knowing a real value range before answering one especially important. This is an estimate, subject to verification of your specific interest, not an offer.
Campbell County is Powder River Basin Niobrara play acreage, in the core of the Powder River Basin around Gillette. The producing rock under Campbell County includes the Niobrara, Big George coal, and Minnelusa, giving owners a royalty check drawn from both oil and gas. Carbon Creek Energy LLC, EOG Resources INC, and High Plains Gas LLC are among the operators on record here. The most recent drilling on record was spudded in 2022. Owners in Campbell County often sell to capture value while operators are active, to settle an estate, or because they would rather hold cash than manage a fractional interest from out of state.

Producing interests in the Powder River Basin Niobrara play are valued on the standard income multiple, roughly 36 to 72 times the average monthly royalty check, and the heavy, active development here can support the upper part of the band where wells are strong. Because production is a mix of oil and gas, value moves with both oil and gas prices. This is an estimate, subject to verification, not an offer.
How Campbell County minerals are valued
Producing interests anywhere are valued on a multiple of the income they pay: roughly 36 to 72 times your average monthly royalty check, the same as 3 to 6 times your annual royalty. Average your last three to six checks, then multiply. Where you land inside that band depends mostly on how fast your wells decline, plus the operator, royalty rate, and any undeveloped drilling upside.

Who buys mineral rights in Campbell County
Campbell County owners hear from brokers, marketplaces, and direct buyers. A broker lists your interest and takes a commission, usually up to 6 percent of your proceeds. Ironwood Royalty is a principal buyer, which means the offer comes from us and there is no commission in the middle. We show you a value range before we ask for anything, explain the undeveloped upside instead of quietly keeping it, and never use a 72-hour deadline to rush a decision on a generational asset.
How to sell Campbell County minerals
The order of operations is the same everywhere, and it protects you:
- Know your value range before you talk to any buyer.
- Ask every buyer to quote per net royalty acre so offers are truly comparable.
- Ask directly whether the offer accounts for undeveloped drilling upside.
- Confirm the price is firm and not subject to a quiet reduction during due diligence.
