Almonty Begins Commercial Mining at Sangdong Tungsten Mine

TORONTO--(BUSINESS WIRE)--Dec 16, 2025--

Almonty Industries Inc. (“Almonty” or the “Company“) (NASDAQ: ALM) (TSX: AII) (ASX: AII) (Frankfurt: ALI1), a leading global producer of tungsten, today announced the first truckload of ore has been successfully delivered to the ROM (Run-of-Mine) pad at the Sangdong Mine, a pivotal transition from early-stage mine development to active mining operations and the final step before commencement of commercial production.

Lewis Black, President and Chief Executive Officer, said: “This first ore placement represents a strategic inflection point in advancing Almonty’s mission to strengthen the global tungsten supply chain. Sangdong plays a critical role in efforts by the United States, the European Union, and Korea to diversify away from the China-dominated market, which currently supplies more than 80% of the world’s tungsten. The resumption of production at the Sangdong Mine forms the foundation for securing reliable, non-China tungsten supply to key sectors such as defense, semiconductors, AI hardware, aerospace, and other high-technology industries.”

The ROM pad functions as a staging area for ore that has just been brought out of the ground. Ore is first obtained inside the mine gallery through controlled blasting, then collected and transported through the haulage system. From there, a truck delivers it to the ROM pad, where it is stockpiled by grade before processing begins.

The ore placed on the ROM pad will now proceed to primary and secondary crushing, followed by grinding to achieve the particle size required for processing. The material will then advance to the flotation circuit, where tungsten-bearing minerals are selectively separated, concentrated, dried and packaged before being supplied to downstream customers. After stability and performance verification of the processing stages, the project will then move to the production stabilization phase as the mine advances toward full-scale commercial operation.

“Our team has completed all key preparatory work including geological assessment, ground stabilization, load testing, and equipment installation to advance the project to this milestone,” said Arif Priyambodo, General Manager of Processing Operations. “The first truckload of ore provides direct confirmation that the ROM pad is ready for operation and that the haulage routes, equipment coordination, and operator workflows are performing safely and effectively under production-level conditions. This successful verification demonstrates that the technical foundation of the Sangdong Mine is now firmly established, enabling the commissioning of the crushing, milling, and flotation circuits to proceed as planned and supporting a smooth ramp-up toward full production.”

CEO Black emphasized that the Sangdong Mine is the foundation of a new tungsten supply chain for the US and its allies beyond Chinese control, as well as returning Korea to its historic role as a key supplier of tungsten, “In the longer term, the Sangdong Mine’s production, combined with our upcoming tungsten oxide plant and the planned development of the molybdenum deposit, will form the basis of a fully integrated strategic-mineral value chain referred to as the ‘Korean Trinity’. This system will position Korea as a global hub for the production, refining, and upgrading of tungsten. It will also support U.S. defense procurement requirements mandating non-China tungsten sourcing after 2027 and reduce Korea’s heavy dependence on Chinese tungsten oxide imports, significantly enhancing national resource security for the United States and its allies.”

Almonty Begins Commercial Mining at Sangdong Tungsten Mine

President Donald Trump’s top Cabinet officials overseeing national security are expected back on Capitol Hill on Tuesday as questions mount over the swift escalation of U.S. military force and deadly boat strikes in international waters near Venezuela.

Defense Secretary Pete Hegseth, Secretary of State Marco Rubio and others are set to brief members of the House and the Senate amid congressional investigations into a military strike in September that killed two survivors of an initial attack on a boat allegedly carrying cocaine. Legal experts say it could have been a war crime, or murder. On the eve of the hearings, the U.S. military announced three more boat attacks targeting “designated terrorist organizations,” killing eight more people.

Here's the latest:

“It seems like another example of the pay-to-play administration,” said Kedric Payne, who leads the ethics program at the nonpartisan Campaign Legal Center in Washington. “There is clearly a perception that in order to get favorable policies and acts from the administration, a company needs to provide a financial benefit to the president.”

Trump Media did not respond to specific questions about the arrangement. “Neither the President nor his family have ever engaged, or will ever engage, in conflicts of interest,” White House press secretary Karoline Leavitt said in a statement.

Crypto.com was under siege for more a year, told enforcement action was likely as part of an aggressive Biden administration push to regulate the cryptocurrency industry. Then Donald Trump won the 2024 election, and the company’s legal peril dissipated.

By August, Crypto.com announced it was plunging roughly $1 billion worth of assets into a venture with a new partner — Trump’s social media company, which had lost hundreds of millions of dollars since its 2021 launch.

Legal and ethics experts say Crypto.com’s journey from investigative target to Trump business partner provides a case study of conflicts of interest as Trump family businesses enter lucrative arrangements with federally regulated companies, some of which have benefited from action taken by his administration.

Hegseth, Rubio and others are set to brief members of the House and the Senate behind closed doors as the U.S. is building up its presence with warships, flying fighter jets near Venezuelan airspace and seizing an oil tanker as part of its campaign against Venezuelan President Nicolás Maduro, who has insisted the real purpose of the U.S. military operations is to force him from office.

Trump’s Republican administration has not sought any authorization from Congress for action against Venezuela. But lawmakers objecting to the military incursions are pushing war powers resolutions toward potential voting this week.

The Trump administration said in a court filing Monday that the president’s White House ballroom construction project must continue for unexplained national security reasons and because a preservationists’ organization that wants it stopped has no standing to sue.

The filing was in response to a lawsuit filed last Friday by the National Trust for Historic Preservation asking a federal judge to halt President Donald Trump’s project until it goes through multiple independent reviews and a public comment period and wins approval from Congress.

The administration’s 36-page filing included a declaration from Matthew C. Quinn, deputy director of the U.S. Secret Service, the agency responsible for the security of the president and other high-ranking officials, that said more work on the site of the former White House East Wing is still needed to meet the agency’s “safety and security requirements.” The filing did not explain the specific national security concerns; the administration has offered to share classified details with the judge in a private, in-person setting without the plaintiffs present.

Here’s a look at key moments in Trump fights with the media in his second term:

The 33-page lawsuit filed in Florida accuses the BBC of broadcasting a “false, defamatory, deceptive, disparaging, inflammatory, and malicious depiction of President Trump,” calling it “ a brazen attempt to interfere in and influence ” the 2024 U.S. presidential election.

It accuses the BBC of “splicing together two entirely separate parts of President Trump’s speech on January 6, 2021” in order to ”intentionally misrepresent the meaning of what President Trump said.” It seeks $5 billion in damages for defamation and $5 billion for unfair trade practices.

The broadcaster apologized last month to Trump over the edit of the speech he gave before his supporters stormed the U.S. Capitol. But the publicly funded BBC rejected claims it had defamed him, after Trump threatened legal action.

BBC chairman Samir Shah had called the edit an “error of judgment,” which triggered the resignations of the BBC’s top executive and its head of news.
