Almonty Industries expands drilling program at Sangdong molybdenum project

Drilling to Date Confirms Grades Consistent with Historical Results as Almonty Accelerates Molybdenum Campaign Amid South Korea’s Supply Crisis Almonty Industries Inc. (NASDAQ: ALM) (TSX: AII) (ASX: AII) (Frankfurt: ALI1), a leading global producer of tungsten concentrate, today announced an update on its large-scale drilling program at the Sangdong Molybdenum Project adjacent to Almonty’s Sangdong Mine in Yeongwol, Gangwon Province, South Korea, to confirm molybdenum resources ahead of future project development. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260616660383/en/ Figure 1. – The mineralized area is extensive, with multiple high-grade intersections Molybdenum is a strategic metal that can significantly enhance heat and corrosion resistance when added in small amounts to steel or specialty alloys.

It is widely used in high-temperature and high-pressure industries such as aerospace, defense, nuclear energy, and petrochemicals. More recently, demand has expanded into next-generation industries including semiconductors and renewable energy. Additionally, the spot price of molybdenum has increased by approximately 23.5% over the past year to 592.34 CNY/Kg. (Source – www.dailymetalprice.com ) The drilling program re-examines mineralized structures identified in historical drill holes and also is aimed at enhancing resource categorization.

Almonty is accelerating its molybdenum drilling campaign to address South Korea’s molybdenum supply shortage, which has recently reached a crisis level. With the national stockpile falling short, the South Korean government has issued public notices urging private companies to secure molybdenum. To date, approximately 37% of the 26 planned drill holes, which will cover approximately 12,000 meters in total, have been drilled.

The assays received thus far have grades similar to those of historical drill holes. Once the full extent of the molybdenum ore body at Sangdong is confirmed, Almonty plans to begin mining without delay. Lewis Black, Chairman, President and Chief Executive Officer of Almonty Industries, commented, “The early results from this campaign are highly encouraging.

With approximately 37% of the program complete, the grades we are encountering are consistent with the historical data, reinforcing our confidence in the scale and quality of the molybdenum resource at Sangdong. We are advancing this work with urgency, as South Korea confronts a critical shortage of molybdenum, and we believe Sangdong Molybdenum Project can become a stable, allied source of supply for a metal that is vital to defense, energy and advanced manufacturing.” “Molybdenum is a natural extension of the infrastructure and expertise we have already established at Sangdong for tungsten. Advancing both metals together allows us to build long-term value for shareholders while supporting national resource security, strengthening the regional economy and reducing the nation’s dependence on imports.

Once the full extent of the ore body is confirmed, we intend to move into production without delay.” As previously announced, the Company conducted a reassessment of its mining portfolio and concluded that, on the basis of its current strategy, including management’s focus and the deployment of resources on the Sangdong Tungsten Mine and the expected economic importance to Almonty of the expected production at the Phase I of the Sangdong Tungsten Mine relative to its other properties, as well as the expected timing and significant potential production increase of Phase II, the Sangdong Tungsten Mine is the only mineral project on a property that is material to the Company for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects and the only material mining project for the purposes of the ASX Listing Rules. The Company remains engaged in the operation and development of other mineral properties, including the Sangdong Molybdenum Project.
