Exhibit 99.1

Almonty Industries Joins Large-Cap Russell 1000® Index and Broad-Market Russell 3000® Index

Dillon, MT – June 29, 2026 – Almonty Industries Inc. (“Almonty” or the “Company”) (NASDAQ: ALM) (TSX: AII) (ASX: AII) (Frankfurt: ALI1), a leading global producer of tungsten concentrate, today announced that it has joined the large-cap Russell 1000® Index and the broad-market Russell 3000® Index, effective with the opening of United States equity markets today, Monday, June 29, 2026, upon the conclusion of the 2026 Russell indexes reconstitution.

The June 2026 reconstitution of the Russell U.S. Indexes captures the 3,000 largest U.S. stocks, ranking them by total market capitalization. The Russell 1000® Index, which is a subset of the Russell 3000® Index, is a U.S. stock market index that tracks the 1,000 largest publicly traded companies in the U.S. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.

Lewis Black, Chairman, President and Chief Executive Officer of Almonty Industries, commented: “Given the FTSE Russell builds these indexes on objective, market-capitalization criteria, qualifying for the Russell 1000® and Russell 3000® is a milestone Almonty earned on the numbers, not by invitation. To us, it signals that the market now recognizes the scale we have reached as a Western-aligned producer of a metal that the defense and advanced-technology sectors cannot do without. Just as important, index membership connects Almonty with the large universe of index-tracking funds and benchmark-driven institutions that allocate to Russell constituents, many of which were unable to hold our shares before today. We view that as the basis for steadier trading liquidity and a more durable base of long-term shareholders.”

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. According to data as of the end of June 2025, approximately $12.2 trillion in assets are benchmarked against the Russell U.S. indexes, which belong to FTSE Russell, the global index provider. For more information on the Russell 1000® and the Russell 3000® Indexes and the Russell indexes reconstitution, please visit the “Russell Reconstitution” section on the FTSE Russell website.
