Since 1966 the DNR has offered nonferrous metallic mineral leases on state-owned mineral rights through a public competitive sealed bid offering known as the Metallic Minerals Lease Sale.

Nonferrous metallic minerals refers to all metals except iron ore and taconite. The metallic minerals state lease category includes elements such as copper, nickel, platinum, palladium, gold, silver, cobalt, chromium, zinc, lead, bismuth, tin, tungsten, tantalum, niobium.
A state metallic mineral lease grants the lessee authority to explore for a mineral deposit but with certain conditions. The lessee is under lease terms that have conditions to help protect the public and environment (see lease form). Any exploration on state land requires the explorer to send an Exploration Plan to the DNR for approval before any exploration on the ground can begin. If a lessee does discover a mineral deposit, environmental review and mining permits are mandatory before mining can begin.

Why does the state lease its minerals?
The state leases its minerals on school trust lands to fulfill its fiduciary obligation to raise revenue for the Permanent School Fund. Minerals have generated about 80% of the historic total revenue to the Permanent School Fund. The state also has fiduciary responsibilities to raise revenues for the Permanent University Fund and the taxing districts and meets those responsibilities by leasing minerals on university trust lands and minerals acquired by the state through tax forfeiture.
The leasing of state-owned minerals supports the state’s policy “to provide for the diversification of the state’s mineral economy through long-term support of mineral exploration, evaluation, environmental research, development, production, and commercialization.”
