Exhibit 99.1

Almonty Issues Shareholder Letter and Provides Corporate Update

DILLON, Montana – September 29, 2026 – Almonty Industries Inc. (“Almonty” or the “Company”) (NASDAQ: ALM) (Frankfurt: ALI1), a leading global producer of tungsten, today issued a letter to shareholders from Lewis Black, Chairman and Chief Executive Officer of Almonty.

Dear Fellow Shareholders,

When I last wrote to you, I described our Sangdong Tungsten Mine (“Sangdong”) as the foundation of our strategy to build a secure, Western-aligned tungsten supply for the United States and its allies. As announced last week, we have now produced the first bags of tungsten concentrate at Sangdong, ready for export. This is a defining moment for Almonty and for Western supply chains: tungsten mined and processed in an allied nation is now a reality. The timing is fitting. Last week, South Korea celebrated Chuseok, its traditional harvest festival, and our team and partners in South Korea are celebrating Sangdong’s first harvest alongside it. With Phase 1 producing and Phase II now underway, Almonty is sailing at full wind and is firmly on the path to becoming one of the largest non-Chinese tungsten producers in the world.

Despite the numerous headwinds we have faced along the way, right up until recently, we have kept our focus and kept our promises. Again, we have shown the market that our actions speak louder than our words, and we are now harvesting the fruits of years of hard work. We have strengthened our operational foundation, expanded our global footprint, built a strong management team and raised our profile in the capital markets and, during 2026, that groundwork has turned into tungsten production.

Sangdong: Thirty-Three Years in the Making

In 1993, the processing plant at Sangdong fell silent, and one of the world’s great tungsten deposits went quiet with it. For more than three decades, the ore stayed in the mountain, waiting.

Last week, that silence ended. Our Sangdong team gathered at the processing facility to watch the first tungsten concentrate come off the line, the first tungsten produced at Sangdong in thirty-three years. For many of the people standing there, it was the result of years of engineering, construction, commissioning, and quiet persistence through every difficult stage of development. For South Korea, it marked the return of a historic mine. For the West, it marked the arrival of the strategic tungsten source it can rely on.

Today, Sangdong is no longer a future promise. The mill is running for 13 hours a day, seven days a week, which will be increased to 24 hours a day, seven days a week, over the coming days. Behind the mill, we have already built a stockpile of approximately 4.6 months of material on site which I would like to reduce as I have no space left for external ore storage. At night when you pass the mineral light over the area, it fluoresces a beautiful deep blue that only higher grade scheelite does. That gives the plant a steady supply of feed for ramp-up and first production, so the mine and the mill can each advance at their own pace. Every tonne that passes through the plant brings Almonty closer to full commercial production, and every bag of concentrate that leaves the site is tungsten that did not exist in the market a week ago.

Sangdong Phase II: The Next Chapter Is Already Underground

The stockpile on the surface does more than feed the mill. It buys us time, and we are putting that time to work. With enough ore on-hand to carry Phase 1 through ramp-up and early production, our mining teams have been free to turn their attention deeper into the mountain, where underground development for Phase II is already well underway.

While the drills advance below ground, the mill above it has gained an important partner. Metso, a global leader in minerals processing technology, is on site at Sangdong, working alongside our operators to support the Phase 1 ramp-up. The same engineers helping us fine-tune today’s plant are laying the technical groundwork for tomorrow’s future.

That brings me to the news many of you have been waiting for.

Phase II is officially a go.

Underground development is progressing, and we are placing orders with Metso for the equipment that will power the expansion, including new mills. The same partner that helped bring Phase 1 to life will now help build its successor. We expect Phase II to be completed in 2027, further ramping capacity to up to 1.2 million tonnes per annum and positioning Sangdong to potentially produce over 460,000 MTU annually, making it one of the largest tungsten mines outside of China and definitively the largest producing currently.

Thirty-three years ago, Sangdong went quiet. This week it came back to life. Before the first year of production is completed, we will already be building its second act.

Putting Our Money Where Our Mountain Is

We have always believed that the best way to show confidence is to act on it. Since launching our previously announced share repurchase program, Almonty has bought back for cancellation 2,914,739 common shares for a total of approximately US$48 million. We did this because we believe our share price does not yet reflect what we are building: a producing mine at Sangdong, a fully funded Phase II expansion, and a strategic position at the heart of Western tungsten supply.

We intend to keep buying, leveraging our fortress balance sheet. Like every listed company, Almonty goes through regular trading blackout periods, for example ahead of financial results, when the Company and its directors, officers and key employees cannot trade. To ensure these periods do not interrupt the program, the Company intends to implement an automatic repurchase plan that is compliant with securities laws. Under this plan, our broker can continue buying shares on the Company’s behalf according to pre-set instructions, including during blackout periods.

The timing and number of any repurchases will depend on market conditions, share price, regulatory requirements and other factors, and the program may be suspended or discontinued at any time.

Beyond Sangdong: Tungsten Already Above Ground

While Sangdong builds for the long term, the West needs tungsten now. We are meeting that need in part by recovering tungsten that has already been mined.

In Spain, Los Santos is returning to work. Our Los Santos Mine has been on care and maintenance since 2020, and its tailings still hold valuable tungsten. We have signed a multi-year, take-or-pay offtake agreement covering at least approximately 1,720 tonnes of contained WO₃ recoverable from those tailings. The result is a fast-track source of European Union (“EU”) origin tungsten with a committed customer in place from the first day of production.

Although no one has commercially recovered tailings in the West so far, we spent four years investigating how best to do it. We may not be the most handsome looking team, but we know Tungsten better than anyone else given how long we have been successfully doing it, and doing it in much more trying times than we currently find ourselves in.

If this initial tailings project proceeds as planned, then we can turn our attention to our 136 years worth of tailings in Portugal and from there to any abandoned site in the EU which has to be reclaimed. I have always spoken to the fact that we survived the last twenty plus years by being extremely efficient and innovative. Pivoting to tailings in the EU, when permitting mines there appears to be next to impossible, clearly demonstrates that we have not forgotten where we came from.

In Africa, we have taken our first step with a new partner. Earlier this month, Almonty and the Government of Rwanda formed Almonty Rwanda, a joint venture in which the Government will hold a 25% position in exchange for contributing the Shyorongi tungsten exploration concession and a mineral processing license. Rwanda is the only African country among the world’s ten largest tungsten producers. Through the partnership, we can collect, upgrade and export ore, pre-concentrate and tailings that Rwanda’s miners are already producing today, while we explore for the future and work toward a centralized processing plant. It is the first of several avenues we are pursuing, at the request of the Western tungsten industrial base, to close the supply gap faster. All under the Almonty and Rwandan Government banner.

Old tailings in Spain, existing production in Rwanda, and a mountain in Korea that waited thirty-three years share one purpose: putting more Western tungsten into the market, sooner.

Closing Thoughts

There will always be voices that doubt, and there will always be reports that predict the worst. Our answer to them has never been words. It has been tonnes of ore through the mill, bags of concentrate leaving the site, industry-high margins and agreements signed with governments and industry leaders. In my view, tungsten has never mattered more than it does today. It is in almost everything that powers modern life, from the phone in your pocket to the car you drive, the aircraft overhead and the equipment that defends our country and its allies.

In most of those applications there is simply no substitute. Demand does not disappear because someone writes that it will. The world needs tungsten, and it needs it from reliable sources it can trust. Demand destruction occurs due to lack of availability, not price.

After more than a decade of hard work, I am proud to see Almonty growing, against every headwind, into a company that the industrial base always knew we were. On behalf of the entire team at Almonty, I would like to thank my fellow shareholders for their continued support and confidence.

Sincerely,

Lewis Black

Chairman, President & Chief Executive Officer
