Berlin Royalties has no affiliation with Flat River Minerals. We compete with them. Everything below is drawn from their own website, their Better Business Bureau profile where one exists, and other public records, and each item is sourced so you can check it. We have not characterized their conduct, their pricing, or their integrity, and we do not intend to. Where sources disagree with each other, we say so rather than picking one. Our own entry is in the same directory, in the same format.

How to check Flat River Minerals, or any mineral buyer

This is the part that is actually useful, and it works on us too. Run it on every company that writes to you.

Look them up in the county records where your minerals are. This is the single best test and almost nobody does it. A buyer who holds what it buys records deeds in its own name in your county. Search the grantee index at the county clerk's office for the company name. If a company has been buying in your county for years, there will be a paper trail. If there is nothing, ask why. Our well records by state page links the public search systems.
Ask whether they are buying for their own account or reselling. A direct buyer keeps the interest. A broker or marketplace finds someone else to buy it and is paid out of the transaction. Neither is wrong, but they are different deals with different economics, and you should know which one you are in. Ask the question in writing.
Ask them to show the arithmetic. Which wells, what decline assumption, what remaining locations, what multiple, and why that multiple. A number with no reasoning behind it is not a valuation. Any buyer can produce this in a paragraph if they actually did the work.
Ask whether the offer letter number and the closing check number are the same. Get the answer in writing, and ask what happens if they find a title issue. This is where most of the real complaints in this industry come from.
Ask who pays the closing costs, and whether there is any cost to you at any point.
Ask them when you should not sell. A buyer with a real answer to that question is worth more of your time than one without.
Shop the offer. Get a second number. A buyer who discourages you from doing that is telling you something. We say this knowing it works against us as often as it works for us.

We put our own version of this list on ten questions to ask any mineral buyer, which we wrote against ourselves before we wrote it about anyone else.

Got an offer from Flat River Minerals? Let us look at it.

Send us the letter and a recent check stub. We will value the interest independently, show you the reasoning, and give you our own number. If theirs is better than ours, we will tell you that plainly and you should take it. If we think you should not sell at all, we will tell you that too. Free, no obligation, and we will not put you on a mailing list.

Who we are, for comparison

Berlin Royalties is the trade name; title is taken as Berlin Resources LLC. We are in Tulsa, Oklahoma, we have been buying since 2014, and we are run by Stephen Clayman, a former Marine Corps officer and career landman. We buy for our own account and hold rather than flipping. We pay all closing costs. We publish how we value interests and when we think you should not sell. Our full entry is in the directory in the same format as everyone else's, and our deeds are in the county records under Berlin Resources, where you can check them.
