ADAMERA MINERALS ESTABLISHES WASHINGTON TUNGSTEN HUB TO ADVANCE DOMESTIC U.S. SUPPLY

Adamera Minerals Corp. has established the Washington tungsten hub, consolidating four scheelite-bearing tungsten properties across northeastern Washington, to advance domestic United States tungsten supply. The hub is being established ahead of a Jan. 1, 2027, federal procurement deadline that will bar tungsten from China, Russia, Iran and North Korea from certain U.S. defence applications at a time when the United States has no operating domestic tungsten mine.

Key highlights:

• Strategic domestic positioning: A structural global tungsten supply shortage and an approaching U.S. defence procurement deadline have fundamentally reset the value of domestic brownfield tungsten assets. Adamera's Washington tungsten hub is positioned to respond.
• Formation of the Washington tungsten hub: Four properties with known tungsten mineralization, consolidated under single ownership for the first time, creating district-scale exploration and development potential.
• Pathway to near-term production: Underground rehabilitation at Talisman and Tungsten Ridge provides direct access to known mineralization, while surface exploration creates the opportunity to expand it.

A centralized strategy

The four properties within the hub share a common geological setting, scheelite-bearing tungsten mineralization hosted within carbonate skarn systems that have demonstrated past production. Consolidating these closely located assets under a unified program creates the potential to scale both production and project size through centralized logistics, shared infrastructure and co-ordinated exploration.

"The Washington tungsten hub provides Adamera investors direct exposure to what I believe is a district-scale brownfield tungsten portfolio at a time when tungsten prices have already risen 900 per cent in response to restricted supply and increased demand. This supply/demand imbalance is not a short-term problem, the work being done across the industry is urgent and we are just beginning to understand what our district holds," states Mark Kolebaba, president and chief executive officer of Adamera Minerals.

The Washington tungsten hub

Initially the company's focus will be to determine the scalability of tungsten development in this region. The four primary assets are as follows:

• Talisman (flagship): A past-producing underground tungsten and base metals mine. Historical records indicate tungsten grades of 0.35 per cent to 1.0 per cent WO3, with zones reporting 5 per cent copper and 103 grams per tonne silver. The copper and silver credits are consistent with the polymetallic nature of these skarn systems and represent potential byproduct revenue that could help support project economics. Other zones are reported to have carried lead and zinc. Underground workings are partially open and Adamera has identified additional exploration targets across the property requiring systematic follow-up.
• Tungsten Ridge: A past producer of tungsten, copper, molybdenite and silver. Historical records report tungsten grades of 0.1 per cent to 7.6 per cent WO3 across multiple mineralized zones and working levels, with higher values reflecting selective samples from higher-grade shoots rather than bulk estimates. Underground workings remain open or partially open. Additional untested targets have been identified and require exploration follow-up.
• Pierre Creek tungsten: A recently staked property with a known tungsten-copper-gold occurrence and evidence of past mining activity. Pierre Creek expands the footprint of the hub and adds an early stage exploration asset to the portfolio.
• Roosevelt tungsten skarn front: Located on Adamera's Buckhorn 2.0 property, north of Kinross Gold's past-producing Buckhorn gold mine, are several tungsten bearing skarns including the Magnetic and Roosevelt mines. Adamera has identified tungsten anomalies on the property within its Buckhorn sample database.

Advancement and development plan

To advance the Washington tungsten hub, Adamera plans to conduct both surface exploration and underground rehabilitation as follows:

• Surface exploration drilling: Systematic surface exploration and drilling across the Hub, with initial focus on the Talisman property. Work is planned to commence shortly.
• Subsurface rehabilitation: Advancing contractor engagement to re-establish safe access to the historic workings at Talisman and Tungsten Ridge, with the objective of characterizing mineralization continuity at depth.
• Financing: Adamera is pursuing strategic partnerships and capital markets financing to advance the Washington tungsten hub, with timing aligned to the January, 2027, procurement deadline.

Tungsten -- a strategic metal

Tungsten is classified as a critical mineral by both the United States and the European Union. Ammonium Paratungstate (APT), the primary international pricing benchmark, surged from approximately $340/mtu (metric tonne unit, WO3) in early January, 2025, to approximately $3,150/mtu by mid-2026, an increase of roughly 900 per cent in 18 months.

This price surge reflects the convergence of Chinese export controls, which have sharply reduced the flow of tungsten to western markets, with increasing demand from the defense, aerospace, cemented carbide and semiconductor sectors. Tungsten's applications in armor-piercing munitions, Patriot missiles, THAAD air-defense systems and advanced electronics make it irreplaceable across both defence and civilian manufacturing.

China currently controls approximately 80 per cent of global tungsten mine production. According to the U.S. Geological Survey, the United States imports an estimated 10,000 metric tons of tungsten annually, with no domestic mine production since 2015. Effective Jan. 1, 2027, Section 4872 of the National Defense Authorization Act bars tungsten mined, refined or processed in China, Russia, Iran or North Korea from certain U.S. defence procurement, a structural shift with no domestic primary producer currently in position to meet it.
