Vancouver, British Columbia – TheNewswire - April 30, 2026 — Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) announces it has staked additional mineral claims at the Talisman Tungsten Project in Washington State, more than doubling its land position. With this expanded footprint secured, the Company is now implementing an exploration program to define and rank drill targets. The Company is simultaneously exploring its& recently announced Tungsten Ridge project in Washington State (see Figure 1).

"We have successfully secured strategic ground around our Talisman and Tungsten Ridge projects. As we launch our 2026 exploration campaign on these properties, our focus shifts to developing targets for drill permitting. The historic Talisman Mine is a former high-grade mine that delivered exceptional grades (up to 1.0% WO3), making it an obvious priority for ongoing work. Equally compelling is our discovery of a new occurrence just 700 metres from the Talisman Mine. We are now preparing a comprehensive exploration program to define the intensity and distribution of tungsten mineralization," states Mark Kolebaba, President and CEO of Adamera Minerals.

About the Talisman Tungsten Project

The Talisman Project covers the historic Talisman Mine, a mine known for historic high-grade tungsten mineralization ranging from 0.35% to 1.0% WO3. The mineralization is characterized by skarn containing scheelite as the primary tungsten mineral. Adamera&s exploration efforts have expanded the project's potential beyond the historic mine. This is highlighted by a new 0.33% WO3 discovery situated approximately 700 metres from the historic mine workings. This new target area remains to be followed up.

Talisman Program for 2026

The 2026 program is designed to define specific, drill-ready targets through a tiered, systematic approach:

• Magnetic Inversion: Completing a 3D inversion of ground magnetic data to image the structural controls at depth.

• 3D Predictive Modelling: Integrating historical mine data with modern magnetic surveys and detailed topography to build a robust 3D predictive model.

• Geophysical Surveying: Executing a ground VLF-EM survey over the property to delineate shallow conductive zones.

• Geochemical Fingerprinting: Conducting comprehensive soil surveys to identify geochemical halos that coincide with magnetic and conductive anomalies.

• Field Validation: Ground-truthing high-priority anomalies, to specifically advancing the 0.33% WO3 discovery located 700m south of the historic mine.

• Target Ranking and Permitting: Finalizing the drill plan to test the highest-priority skarn targets and securing the necessary drill permits.

Market Context: Tungsten, The Essential Metal

Tungsten's unique physical properties, including extreme hardness, a very high density, and the highest melting point of any metal make it an essential element in machining, electronics, aircraft manufacture and military applications.

These unique physical properties mean that tungsten cannot be easily substituted by other metals or materials. This has made it relatively price-insensitive for most uses. As a result of global conflicts, military application demand is expected to increase by approximately 12% in 2026, with similar demand growth expected in coming years.

Tungsten is considered a critical metal. Western governments are actively seeking to increase non-Chinese supply. The global market is in a structural deficit and many countries favor local producers. In response to the supply squeeze, the US military, via the Defense Industrial Base Consortium (DIBC), recently invited companies to submit proposals to boost domestic supplies of critical minerals, explicitly targeting tungsten.

High-quality tungsten deposits are rare and timelines for permitting and developing mines worldwide are long. While new production coming on stream will help, tungsten prices are likely to remain well above historical levels for an extended period of time.

About Adamera Minerals Adamera is advancing a tungsten portfolio in Washington State to establish a secure, uninterrupted domestic supply for U.S. markets. While leading with this critical mineral strategy, the Company also continues to explore for high-value gold, silver, and copper deposits in BC and Washington State. Adamera is committed to utilizing modern, tech-driven exploration methodologies to efficiently discover and define economic mineral resources and is focused on translating exploration success into tangible equity.
