MLRS Frequently Asked Questions

The Mineral & Land Records System (MLRS) is a new online platform being implemented by the Bureau of Land Management (BLM) to deliver state-of-the-art mineral and land records transactions, tracking, mapping, and more for BLM customers and staff. MLRS will combine many of BLM's current systems (i.e., LR2000, ALIS, and land status records including Master Title Plats) and manual documentation processes to create a more intuitive and efficient way to manage resources and cases across a range of BLM activities. To read more about what MLRS means for you, browse our collection of frequently asked questions below.

Overview   |   Registration   |   Process


What can I do in MLRS?

MLRS is being implemented in phases. Currently you can use the system for mining claim related filings and information. This includes filing new claims, managing existing claims, paying annual maintenance fees, transfers, amendments, and affidavit of assessment work – all online! MLRS will later be expanded to include various other case types.

Can I take action on all of my existing mining claims in MLRS?

Yes, if you register for an MLRS account and find your active claims, you can take action on existing claims that are not closed or on appeal without a stay. If you do not see all the claims you expected to see, you will be instructed to contact the BLM for assistance.

How will MLRS work for lands and realty, or is this just planned for mining?

MLRS is being developed in modules. The first module is for mining claims; the second will be for oil, gas, and geothermal; and the third will be for lands and realty, where we will work through solid minerals, rights of way, and other lands and mineral cases in LR2000.

Will Master Title Plats (MTPs) no longer be used with implementation of MLRS?

The National Land Status Database will eventually replace MTPs. MLRS is being implemented in phases; one of the last phases will be to create an MTP product that will replace the existing black and white maps used today.

Should I register for MLRS with a Business or Personal account?

Your account type will be determined by your needs.

You will create a personal account if you own your claims as an individual and will be the only user within the account.

You will create a Business Account if your claims are owned by a business. With a business account, you plan to add employees to the account, and/or you will be using a business email.


Is the Mining Claims process changed by MLRS?

The overall mining claims process remains the same. The primary difference is that, for your convenience, many transactions are now able to be completed online.

How does the 90-day deadline to file a mining claim change with MLRS?

MLRS does not change any of BLM's existing policies. Therefore, the 90-days-to-file deadline has not changed.​

How do I file a mining claim in Alaska using MLRS?

In Alaska, you will not be able to file a mining claim in MLRS until the final module is released in 2022. Until then, continue to follow your current processes for filing a mining claim..

Will MLRS let me know if there is an issue with my legal land description (LLD)?

Yes, MLRS has data validation that informs you in real time if the land description you are entering is invalid. In the event that you do submit a LLD that is inaccurate, BLM adjudicators will notify you via email and/or mail​.

Can I file a mining claim before I place my claim notice on the ground?

No, MLRS does not change any of BLM’s existing policies. You are required to place your notice on the claim first before you file with the county or BLM​.

Do I still need to file my claim with the county?

Yes, county filing requirements remain the same​.

Does MLRS accept electronic signatures for forms that typically require handwritten signatures?

During the first release, electronic signatures are not available as current policy requires handwritten signatures on certain documents. However, we are working toward being able to accept digital signatures. Until then, you need to mail or deliver in-person to the BLM office any documents that require handwritten signature.

Do I still need to visit the public room?

MLRS allows you to do many of the same mining claims tasks done at public rooms, but online. Documents requiring original signatures can be mailed in rather than dropped off in person. But you can always visit the public room if preferred.
