In a move poised to unlock vast mineral resources critical to America’s energy transition and national security, President Donald Trump has approved the construction of a 211-mile access road to Alaska’s remote Ambler Mining District.
This decision reinstates a project initially greenlit during Trump’s first term, only to be rescinded under the Biden administration, signaling a renewed push for domestic resource development amid growing global demand for critical minerals. The Ambler Access Project, often referred to as the Ambler Road, will connect the Dalton Highway to the Ambler Mining District in Northwest Alaska’s southern Brooks Range.
Spanning approximately 211 miles, the road is designed to provide industrial access to one of the world’s most promising untapped mineral belts, facilitating exploration and extraction while minimizing environmental impact through controlled development.
Proponents argue it will boost Alaska’s economy, create jobs, and reduce U.S. reliance on foreign supplies of metals essential for electric vehicles, renewable energy infrastructure, and advanced technologies.
The Ambler Mining District: A Treasure Trove of Critical Minerals
Nestled in the rugged terrain of Northwest Arctic Borough, the Ambler Mining District is renowned for its volcanogenic massive sulfide (VMS) and carbonate-hosted deposits, first discovered in the 1970s.
This district spans a 75-mile-long belt rich in high-grade polymetallic resources, making it a focal point for mining exploration.Key known deposits include:Arctic Deposit: A flagship VMS site with an estimated 46.7 million tons of probable mineral reserves, containing copper (3.26%), zinc (4.45%), lead (0.76%), gold (0.64 g/t), and silver (47.6 g/t).
It’s one of the highest-grade copper deposits globally and holds significant cobalt potential.
Bornite Deposit: A carbonate-replacement deposit focused on copper and cobalt, complementing the district’s diverse mineral portfolio.
Sun and Smucker Deposits: Additional advanced prospects featuring copper, zinc, gold, silver, and cobalt, underscoring the district’s multi-deposit potential.
Overall, the district boasts large deposits of copper, cobalt, zinc, lead, gold, silver, gallium, germanium, and even talc.
These minerals are deemed critical by the U.S. Geological Survey for their role in clean energy technologies, with cobalt and copper being particularly vital for batteries and electrical systems.
Exploration efforts, led by companies like Ambler Metals LLC (a joint venture of Trilogy Metals Inc. and South32 Limited), have delineated resources that could position Alaska as a major supplier in the global market.
A Turbulent History: From Approval to Rescission and BackThe Ambler Road project has been a political flashpoint, reflecting broader debates over resource development versus environmental protection.
Trump’s First Term Initiation (2017-2021): In 2020, the Trump administration issued a Record of Decision (ROD) approving the road under the Bureau of Land Management (BLM), citing its potential to tap into Alaska’s “extraordinary resource potential” for energy and minerals.
This aligned with broader policies to streamline permitting and boost domestic mining.
Biden’s Rescission (2021-2025): Upon taking office, the Biden administration halted the project, initiating a Supplemental Environmental Impact Statement (SEIS) and ultimately rejecting the road in 2024 due to concerns over impacts on wildlife, subsistence hunting, and Indigenous communities.
Critics, including environmental groups, argued the road could disrupt caribou migration and fragile ecosystems in the Brooks Range.
Trump’s 2025 Reinstatement: On January 20, 2025—his first day back in office—President Trump issued an executive order suspending the Biden-era SEIS and reinstating the 2020 ROD.
Further actions included transferring 28,000 acres to the Alaska Native consortium NANA and directing the Interior Department to expedite reviews.
By May 2025, Ambler Metals hailed the decision as a step toward responsible development.
Recent congressional support, including a House vote in September 2025, has advanced the project toward implementation.
This back-and-forth highlights the strategic importance of the district, with Trump emphasizing energy independence and economic growth in Alaska, which already ranks as the U.S.’s second-largest gold producer.
Investor Outlook: Key Factors for Alaska Mining Companies
With the Ambler Road approval opening new frontiers, investors are eyeing Alaska’s mining sector, which supports over 11,800 jobs and generates $1.1 billion annually.

The state’s stability, vast untapped resources, and proximity to North American markets make it attractive, but due diligence is essential given regulatory, environmental, and operational challenges.
Here’s what investors should prioritize when evaluating potential mining companies in Alaska:
|
Factor
|
What to Look For
|
Why It Matters
|
|---|---|---|
|
Resource Quality and Reserves
|
Companies with proven, high-grade deposits (e.g., measured and indicated resources) and diversified minerals like copper, gold, and cobalt.
|
Ensures long-term viability; Ambler’s deposits exemplify high potential for scalable production.

|
ESG (Environmental, Social, Governance) Practices
|
Strong commitment to sustainability, Indigenous partnerships (e.g., with NANA), and modern tech for minimal impact.
|
Mitigates risks from environmental opposition and aligns with global standards; key for funding and reputation.
|
|
Financial Health and Management
|
Solid balance sheets, experienced teams, and access to capital via private placements or partnerships.
|
Volatility in commodity prices demands resilience; look for undervalued juniors with growth potential.
|
|
Technological Adoption
|
Use of advanced exploration tools, efficient recovery methods, and risk-reducing innovations.
|
Improves ore recovery and operational efficiency in remote, harsh environments like Alaska’s Arctic.

|
|
Market Positioning
|
Exposure to critical minerals with rising demand (e.g., for EVs and renewables); diversified portfolios.
|
Aligns with global trends; companies like Trilogy Metals or Kinross Gold offer entry points.
|
|
Valuation and Risks
|
Unique, multifaceted valuations considering location, infrastructure, and geopolitical factors.
