Core Natural Resources (CNR) Resumes Longwall Operations at Leer South Mine

The share price of Core Natural Resources, Inc. (NYSE:CNR) surged by 3.98% between December 12 and December 19, 2025, putting it among the Energy Stocks that Gained the Most This Week.

Core Natural Resources, Inc. (NYSE:CNR) is a world-class producer and exporter of high-quality, low-cost coals, including metallurgical and high calorific value thermal coals.

Core Natural Resources, Inc. (NYSE:CNR) received a boost on December 18 when the company revealed that it had resumed longwall operations at its Leer South metallurgical mine in West Virginia. The longwall operations at the site had been idle since the beginning of the year due to a combustion-related event. The company sealed the affected area of the mine and successfully retrieved its equipment, which was generally in good condition despite the prolonged shutdown.

Core Natural Resources, Inc. (NYSE:CNR) now expects a significant improvement in financial performance due to the restart at Leer South. Moreover, the company reported that its West Elk longwall mine in Colorado is also now operating at consistent productivity levels following its transition to the B-Seam.

Jimmy Brock, Chairman and CEO of Core Natural Resources, Inc. (NYSE:CNR), commented:

“On behalf of the entire board and management team, I commend the operations team for making safety their highest priority in the successful recovery, repositioning, and restart of the longwall system. In addition, we want to again extend our appreciation to federal, state and local regulatory officials for their collaboration and support. Leer South is a highly strategic asset, and we fully expect this world-class operation to execute at a high level in 2026 and beyond. While the issues at Leer South and West Elk adversely affected Core’s performance in 2025, we are looking forward to strong cost improvement and profitability at both these operations going forward.”

While we acknowledge the potential of CNR as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.

Disclosure: None.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
