State Mineral Leases

The State of Minnesota issues mineral leases on state-owned and state-administered fee mineral interests. The lease types include iron ore, taconite, industrial mineral, non-ferrous, and miscellaneous. These layers are of active or historic State mineral leases, administered by the Minnesota Department of Natural Resources, mapped to the PLS forty and government lot. When there is no match to the PLS forty or government lot in the PLS40 layer, a record is then matched to the PLS section layer. These layers merge the DNR Control Point Generated PLS layer (PLS40) with land records stored in the DNR's Land Record System (LRS) in Oracle. The data are limited to a forty, government lot, or section level representation. Therefore, any state mineral leases that are less than a forty, government lot, or section, are represented by the entire forty, government lot, or section. <br/><br/>There are four layers included in this geodatabase: <br/>1) active (closed or completed) mineral leases mapped to the PLS forty or government lot, <br/>2) dissolved active mineral leases, where the mineral lease areas have been merged based on specific attributes, such as the lease number (i.e., the DNRTRNXNUM field), type of lease, start and expiration dates, but not the attributes to the PLS forty and government lot, <br/>3) historic mineral leases that have ended, and <br/>4) dissolved historic mineral leases, where the mineral lease areas have been merged based on specific attributes, such as the lease number (i.e., the DNRTRNXNUM field), type of lease, start and expiration and termination dates, but not the attributes to the PLS forty and government lot. <br/><br/>The names for these layers are active_minleases, active_minleases_dissolved, historic_minleases, historic_minleases_dissolved.

dsCurrentRef Time Period of Content date indicates the date which the user can be confident of accuracy and completeness of the dataset. Updates occur weekly, for all of the active State mineral leases layers. The control point generated PLS layer (often referred to as PLS40) was created during the 1990s, with the information based on the General Land Office (GLO) plats and field notes, ranging from the mid-1800s to 1998. Since that time, additional GLO plats have been used to modify the PLS40 layer to incorporate more recent surveys, especially island surveys, and to make corrections to the PLS40 layer. To better map the state ownership, a version of PLS40 was modified to include several non-BLM (Bureau of Land Management) surveys. Note that during processing, any land record that does not match to the PLS forty or government lot is then matched to the PLS section to include as many of the land records as possible in this layer.
