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 Indices, Tract Books).

MLRS is 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 staff, customers, and the public.

The MLRS mining claims module was released on January 25, 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 and mineral estate.
