Mineral & Land Records System (MLRS)

MLRS Overview

The Bureau of Land Management (BLM) is developing the Mineral & Land Records System (MLRS) to replace the Legacy Rehost 2000 (LR2000) case management system, Alaska Land Information System (ALIS), and land status records (e.g., Master Title Plats, Historical Index, Tract Books).

MLRS will be a customer-centric, geospatially-enabled land information system that employs nationally standardized business processes, ensuring the quality and accuracy of land and mineral records and data, while securely delivering land records information to relevant BLM employees, customers, and the public.

The MLRS mining claims module is slated to launch in early 2021. Over the next two years, additional MLRS modules will be released in support of land and mineral use authorizations for oil, gas, and geothermal leasing; rights-of-way; coal and other mineral development; land and mineral title; and withdrawals, classifications, and other actions on Federal lands or on Federal mineral estate.

BLM is using a phased, modular approach to transition all case types into MLRS. We will first release mining claims functionality in MLRS. As we continue to implement our vision, MLRS will provide additional mission-critical BLM services and products such as permits, leases, rights-of-way, and more.
