History of State Leasing and Drilling

50 Years of Leasing History

The state began offering leases for nonferrous metallic minerals in 1966. Listed below is data from 50 years of state metallic mineral lease transactions and associated exploration between January 1966 through December 2016.

Significant summary points from the data:

(1966-2016)

Lease Status Number of Leases Percentage of Total
Active 264 8%
Terminated 3,248 92%
Total 3,512 100%

(1966-2016)

Terminated Leases (3,248 Leases) Percentage of Total Terminated Leases
Terminated within 5 years 85%
Terminated within 6-10 years 13%
Terminated after 10 years 2%
Active Leases (264 Leases) Percentage of Total Active Leases
Less than 5 years old 40%
Lease is between 6 and 10 years old 42%
Lease is greater than 10 years old 18%

 


 

Drilling and Leasing History Analysis

The DNR completed a new analysis of exploratory boreholes (drilling) on state nonferrous metallic mineral leased parcels between January 1966 through 2016. During this time there were 3,512 state metallic mineral leases issued over 24,269 approximate 40-acre leased parcel footprints. It is important to note that some of these parcels have been leased multiple times though are only counted once for this calculation.

The analysis showed that 97.8% of all state nonferrous metallic mineral leased parcels had no exploration drilling on them. There were a total of 1,911 total exploration drill holes that intersected a state leased parcel. Those drill holes intersected 523 leased parcels or 2.2% of all state leased parcels (see table 3).
