Ambler advances, but the U.S. stake in its developer hasn't closed

The Ambler Road is inching forward this year, but the piece that drew national headlines — the U.S. government taking an ownership stake in one of the mining companies behind it — still hasn't happened.

As of this week, Trilogy Metals says the federal government's proposed $35.6 million investment in the company has not closed. Authorized in October 2025 under the Defense Production Act, it would give the government roughly a 10% stake, but the closing deadline has slipped repeatedly, most recently past a July 31 target, as the two sides finalize documents. Trilogy says the letter of intent remains in effect.

The 211-mile industrial road would run from the Dalton Highway to the mineral-rich Ambler district in Northwest Alaska, crossing Gates of the Arctic National Preserve. Its federal permits are back in force: in October 2025, President Trump reversed the Bureau of Land Management's 2024 denial, and the agencies reissued AIDEA's 50-year right-of-way.

The project kept moving in 2026. This spring, the mine it would serve — Trilogy's Arctic Project — entered formal federal permitting with a Clean Water Act application and a fast-tracked review, while AIDEA works on road engineering. The White House projects thousands of construction jobs and more than $1 billion in state revenue, and casts the road as key to domestic critical minerals.

The road divides the region. Ten groups, including conservation organizations and some Alaska Native tribes and subsistence users, are suing over the permits, warning it could fragment caribou migration and damage fish habitat that Northwest Alaska communities depend on. Others, including Alaska's congressional delegation, back the project. The case is pending.
