Hardrock Mining: Updated Information on State Royalties and Taxes

Skip to Highlights

Highlights

GAO identified state laws and regulations governing state-assessed royalties and taxes on hardrock mining operations in twelve western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. In contrast to the federal government, these states charge royalties for hardrock minerals extracted from public lands. Most states also impose taxes on hardrock mining that occurs on any land. These royalties and taxes fall into four categories—unit-based, gross revenue, net smelter returns, and net proceeds—based on how they are assessed and the extent to which various costs are deducted before royalties and taxes are assessed. There have only been minor changes to the royalties and taxes assessed by the twelve western states since GAO last examined these provisions in 2008.
