BILLINGS, Mont. (AP) — House Democrats from some western states are preparing to push for changes to a longstanding law that governs mining on U.S.-owned lands.

Monday, The Government Accountability Office published a report stating the U.S. stands out among some other countries that collect royalties on gold, copper and other minerals.

The U.S. does not typically collect royalties on those minerals. House Natural Resources Chairman Raul Grijalva says the mining industry should pay at least as much as oil and gas companies, which typically pay royalties of 12.5% on resources extracted from federal lands. Past efforts to significantly change the government’s 1872 mining law have failed.
