TORONTOAlmonty Industries Inc. (“Almonty” or the “Company“) (TSX: AII) (ASX: AII) (OTCQX: ALMTF) (Frankfurt: ALI), a leading global producer of tungsten concentrate, is pleased to announce that it has filed an updated technical report (the “Technical Report“) for its Sangdong Tungsten Mine (the “Sangdong Mine“) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101“).

The Technical Report is entitled “NI 43-101 Technical Report on the Mineral Resources and Reserves of the Sangdong Project, South Korea“, dated June 23, 2025 and effective February 28, 2025, and has been authored by Adam Wheeler, B.Sc, M.Sc, C. Eng. (the “Qualified Person“), an independent expert and a “qualified person” within the meaning of NI 43 101. The Technical Report is not required to be prepared pursuant to NI 43-101 and was voluntarily prepared to update the technical report entitled “Report NI 43-101 Technical Report on the Mineral Resources and Reserves of the Sangdong Project, South Korea”, dated July 31, 2016 and authored by the Qualified Person, and reflects recent developments at the Sangdong Mine, including with regards to mine development, to enhance the public disclosure about the Sangdong Mine. The Technical Report has been filed on SEDAR+ and can be accessed under the Company’s profile at www.sedarplus.ca and on the Company’s website at www.almonty.com.

As detailed in the Technical Report, the current mine and processing plant construction of Phase I of the Sangdong Mine is expected to begin production in the second half of 2025. Once fully operational, the targeted ore throughput capacity is expected to reach around 640,000 tons per year. The Company expects to increase its throughput capacity up to 1.2 million tons through the Phase II planned expansion. This expansion is fully permitted under existing Phase I approvals, and during the development of Phase I, some components have been built which may support a higher throughput or expansion. It is expected that, subject to positive operating results from Phase I and prevailing market conditions, Phase II could be advanced as early as 2026. This would involve initiating detailed engineering and permitting activities, followed by potential construction and commissioning. If Phase II is advanced in 2026, it is expected that first ore production under Phase II could commence in 2027. The Phase II expansion is expected to unlock economies of scale and support margin enhancement. Advancement to Phase II is contingent upon a formal decision following the evaluation of Phase I performance.

The Company has also conducted a reassessment of its mining portfolio and has concluded that, on the basis of its current strategy, including management’s focus and the deployment of resources on the Sangdong Mine and the expected economic importance to the Company of the expected production at the Phase I relative to its other properties, as well as the expected timing and significant potential production increase of Phase II, the Sangdong Mine is the only mineral project on a property that is material to the Company for the purposes of NI 43-101. The Company remains engaged in the operation and development of other mineral properties, including the Panasqueira Mine (Portugal) and the Sangdong Molybdenum Project (South Korea).

For more details about the Sangdong Mine, shareholders should carefully review the Technical Report.

Notes Regarding Scientific and Technical Information

The scientific and technical information contained in this news release relating to the Sangdong Mine has been reviewed and approved by Adam Wheeler, B.Sc, M.Sc, C. Eng., an independent expert and “qualified person” within the meaning of NI 43 101.

ASX Listing Rules and ASX Listing Rule 5.12.9 Cautionary Statement

The Company advises that, for the purposes of the ASX Listing Rules, all mineral resources and ore reserves contained in the Technical Report are “foreign estimates” and are not reported in accordance with the Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves (2012) (the “JORC Code“).

Although the Company notes that Mr Wheeler (who is also a Competent Person within the meaning of the JORC Code) previously prepared a JORC-compliant Technical Assessment Report for the Sangdong Project dated 31 December 2020 and this was included in the Company’s prospectus dated 8 June 2021 (the “JORC Compliant Technical Report“), the JORC Compliant Technical Report does not include the current assumptions, parameters and methods included in the Technical Report. As such:

  • a competent person has not done sufficient work to classify the updated foreign estimates contained in the Technical Report as mineral resources or reserves in accordance with the JORC Code; and
  • it is uncertain that following evaluation and/or further exploration work that the updated foreign estimates contained in the Technical Report will be able to be reported as mineral resources or ore reserves in accordance with the JORC Code.

Information required pursuant to ASX Listing Rules 5.12, 5.16 and 5.17 is included in Annexure A of this announcement. Please download the release to access this content.
