In a significant boost for the U.S. coal industry, the Trump administration has greenlit a mining plan modification for the Antelope Mine in eastern Wyoming. This approval, announced by the Interior Department under Secretary Doug Burgum, expands the mine’s federal coal leasing area by approximately 857 acres, unlocking an additional 14.5 million tons of recoverable coal. The decision extends the mine’s operational life by more than a decade, pushing it through to 2037, and aligns with the administration’s push to enhance domestic energy production, reduce reliance on foreign sources, and support American jobs.
The Antelope Mine, located in the prolific Powder River Basin—the largest coal-producing region in the United States—has been operational since 1985. Managed by the Navajo Transitional Energy Company (NTEC), a wholly owned entity of the Navajo Nation, the mine produces low-sulfur, low-ash subbituminous coal with an average heat content of around 8,850 BTU per pound. This high-quality thermal coal is ideal for powering electricity generation, and the mine has a permitted annual capacity of up to 42 million tons, though typical production hovers between 20-25 million tons annually.

NTEC, the third-largest coal producer in the U.S., oversees multiple operations and reported an estimated 52 million tons of coal production in 2021, underscoring its pivotal role in the energy sector.
This expansion comes at a critical time for Wyoming’s coal industry, which has faced headwinds from declining demand due to competition from cheaper natural gas and renewables. In 2024, Wyoming’s coal output dipped below 200 million tons for the first time since 1992, totaling around 185 million tons.
However, the approval is expected to sustain over 350 full-time jobs at the Antelope Mine and contribute to broader economic stability in coal-dependent communities. The Interior Department’s rigorous environmental assessment concluded no significant impacts from the modifications, paving the way for continued surface mining operations.
Where the Coal Will Be Sold: Domestic Focus with Export Potential
The additional 14.5 million tons of coal from the Antelope Mine are primarily destined for domestic markets within the United States. Historically, 100% of the mine’s output in recent years, such as in 2018, has been shipped to U.S. customers, reflecting the broader trend for Powder River Basin coal.
This coal is transported via rail to power plants across the Midwest, South, and other regions, where it fuels electricity generation. The Powder River Basin’s low-cost production—averaging around $14.40 per ton in committed sales for 2025—makes it competitive for utility buyers seeking reliable baseload power.
While exports have been limited due to logistical challenges and port restrictions on the West Coast, there is potential for international sales if market conditions improve. In the past, such as in 2010, the Antelope Mine shipped 3.3 million tons to Asian customers through export terminals.
Ongoing efforts to expand export infrastructure could open doors to markets in Asia, where demand for thermal coal persists despite global shifts toward cleaner energy. However, current projections indicate that U.S. coal exports from the Powder River Basin will remain modest in 2025, with overall domestic consumption driving the majority of sales.
Key Customers: U.S. Electric Utilities and Power Producers
The primary customers for Antelope Mine coal are major electric utilities and power generation companies across the United States. Similar to neighboring operations like Peabody’s North Antelope Rochelle Mine, which supplies over 40 electricity-generating customers operating more than 80 power plants nationwide, NTEC’s coal feeds a network of domestic power facilities.
Specific buyers often include regional utilities in states like Texas, Minnesota, and Iowa, where coal-fired plants rely on the basin’s subbituminous coal for its compliance-grade qualities that meet environmental standards.NTEC’s broader portfolio, including the Antelope Mine, supports long-term contracts with utilities such as those co-owning plants like the Big Stone Plant in South Dakota, where coal purchase agreements extend through 2023 and beyond.
These contracts ensure stable demand, with shipments typically handled via single-destination trains from Wyoming to end-users.
As the Trump administration emphasizes grid reliability, this approval could strengthen ties with utility customers prioritizing domestic energy sources.
Potential Returns for Investors: Economic Boost for the Navajo Nation and Broader Sector
As a wholly owned subsidiary of the Navajo Nation, NTEC directs its revenues back to tribal communities, making the expansion a direct economic win for the Nation rather than traditional stock market investors.
The unlocked 14.5 million tons could generate substantial revenue over the extended mine life. At current market prices of approximately $14.40 per ton, this equates to potential gross revenues exceeding $200 million, though actual returns would depend on production costs, which average around $10-12 per ton in the Powder River Basin, and market fluctuations.
For broader investors in the coal sector, this approval signals renewed confidence under the Trump administration, potentially lifting stocks of publicly traded companies like Peabody Energy or Arch Resources, which dominate Wyoming production.
NTEC’s financial strength—evidenced by past acquisitions and operational reports showing growth despite industry challenges—positions it for diversified investments in energy and critical minerals.
However, risks remain, including declining overall U.S. coal demand projected to drop by 152 million short tons between 2025 and 2030.
Investors eyeing the sector should monitor export opportunities and policy support for potential upside.
This development underscores the administration’s commitment to revitalizing coal, offering a lifeline to Wyoming’s economy while navigating environmental and market pressures. As production ramps up, the Antelope Mine could play a key role in sustaining America’s energy independence.
