Placer mining application targets Gopher Gulch in salmon-bearing Yentna watershed

A small tributary in the Yentna watershed faces potential mechanical placer mining after Go Gulch Mining LLC filed a Multi Agency Application for Permits to Mine in Alaska, case number A20263225, at Gopher Gulch on state lands. The Alaska Department of Natural Resources received the application on June 20, 2026. Its status is pending, with no posted public comments or objections yet.

The consolidated application triggers coordinated review by the Departments of Natural Resources, Fish and Game, and Environmental Conservation. It also serves as a pre-construction notification under General Permit POA-2014-55, the U.S. Army Corps of Engineers statewide Clean Water Act authorization for mechanical placer mining that runs through October 2031. Proponents argue impacts can be managed under that permit and state Fish and Game stipulations incorporated as special conditions.

Gopher Gulch drains into the Susitna system, which supports Chinook, coho, and sockeye salmon managed for sport and subsistence harvest. Subsistence users and tribal governments have raised concerns in similar Yentna Mining District proceedings about sediment, stream diversion, and access impacts on salmon habitat. Similar Yentna Mining District application notices have appeared in prior years, including at least one other pending application in the district in 2026.

The Department of Natural Resources described the filing as a courtesy notice. "This is a courtesy notice provided to the public," the agency stated. "Your comments about this activity will receive consideration even though this is a courtesy notice provided they are received within 14 days from the posting date of this notice."

The Alaska Department of Fish and Game, one of the reviewing agencies, states its mission is to "manage, protect, maintain, and improve the fish, game, and aquatic plant resources of the state."
