Exhibit 99.1

Almonty Signs Tungsten Offtake Agreement with Sandvik
Group Subsidiary for Recycling of Existing Mine Tailings
Multi-year, take-or-pay agreement covers a minimum
of approximately 1,720 tonnes of contained WO₃, recovered from retreatment of the Los Santos Mine’s existing tailings inventory
with restart of processing plant
DILLON, Montana – September 17, 2026
– Almonty Industries Inc. (“Almonty” or the “Company”) (Nasdaq: ALM) (Frankfurt: ALI1), a leading global
producer of tungsten concentrate, today announced that it has entered into a long-term tungsten concentrate supply agreement with Wolfram
Bergbau und Hütten AG (“WBH”), a subsidiary of the Sandvik Group, covering retreatment (“recycling”) of the
Company’s existing tailings stockpile at the Los Santos Mine in western Spain. The agreement is intended to create an expedited
tungsten supply solution with the ability to deliver concentrate in notably less time than the development of a traditional mine.
The agreement, which includes a conditional pay to
play upfront US$3.0 million one-time payment for the offtake rights, is structured on a take-or-pay basis and is entered into in anticipation
of the re-commencement of production at the Los Santos Mine, an open-pit scheelite skarn operation located approximately 50 kilometres
south of Salamanca that has been in planned care and maintenance since February 2020. Material supplied under the agreement will be drawn
from the retreatment of the mine’s existing tailings inventory.
For Almonty, the agreement establishes a committed
route to market for a restarted European Union asset before production resumes, together with customer capital to support reinstatement
of the processing plant. For WBH, the agreement adds a documented non-Chinese, European Union origin feed source to a smelter that supplies
the Western hard-metal and powder-metallurgy industries.
A Recycled Route to Non-Chinese Tungsten
The agreement pairs two operations built on recovering
tungsten from material that has already been mined once. At Los Santos, Almonty’s restart plan is centred on retreating the tailings
inventory left behind by earlier processing rather than on new primary extraction. Through continuing tests and trials, the Company has
materially improved WO₃ recovery from tailings retreatment.
WBH, which has been part of Sweden’s Sandvik
Group since 2009, operates its refining and powder manufacturing complex at St. Martin in Sulmtal, Austria, where scheelite concentrate
from its own Mittersill mine and concentrate purchased from around the world are processed alongside recycled secondary tungsten materials.
The facility is the only integrated tungsten smelting plant outside of Asia and Russia, and the Sandvik Group’s business unit to
which it belongs also operates a dedicated tungsten recycling capacity.
The agreement comes ahead of a significant change
in United States defense procurement rules. Effective January 1, 2027, restrictions on specified tungsten materials originating in China,
Russia, North Korea and Iran extend back through the supply chain to the mining or production of tungsten ore or feedstock, making documented
non-Chinese origin increasingly important for tungsten entering covered United States defense supply chains.
Management Commentary
Lewis Black, Chairman, President and Chief Executive
Officer of Almonty, said: “WBH is the only integrated tungsten smelter outside Asia and Russia, and recycling is central to how
they operate which makes them a natural fit for what Almonty is doing at Los Santos, where the restart is built around recovering tungsten
from material that has already been mined and processed once.
“What this agreement gives us is a take-or-pay
commitment from a Sandvik Group company, index-linked pricing with a floor beneath it and a sharing of the financial requirements to reactivate
the property. That combination is what allows us to bring a European Union asset back into production with a defined route to market from
the first shipment. This is the first time tailings have been commercially passed in the West to our knowledge and is a culmination of
technology that we have developed since we closed Los Santos in 2020 as it depleted its resource. If successful it will mean we have another
tool to generate supply far quicker than opening of a mine and will continue to alleviate the supply squeeze. We would then also apply
the same technology to our Panasqueira mines tailings and onwards to other abandoned European sites where we reclaim the site and at the
same time recover material from the discarded tailings. Utilizing mobile tailings plants will expedite permit times significantly. This
is now the second supply program we have been working on for the industrial base to sit alongside our recent announcement of small-scale
miner collections in Rwanda. We have further programs that we are currently working on, and this will be announced shortly,” concluded
Black.
