Magnetic Survey Significantly Expands Skarn Potential at Adamera's Tungsten Ridge Property

13:30 Uhr  |  The Newswire

Vancouver, April 8, 2026 - Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) ("Adamera" or the "Company") has identified multiple exploration targets from a detailed ground magnetic survey completed by the Company at the Tungsten Ridge property in eastern Washington State (figure 1). The survey results expand the property's prospective skarn/tungsten mineralization significantly beyond the historical underground mine workings, the results will also guide an upcoming geochemical survey over the property. Adamera is now interpreting the inversion data from the magnetic survey.

Historical exploration at Tungsten Ridge focused almost exclusively on exposed outcrop, leaving vast areas obscured by shallow overburden untested. Adamera's primary objective is now the systematic development of high-priority drill targets using a two-pronged approach. First, evaluation of the area of known mine workings to define and extend high-grade zones of tungsten mineralization. Second, the Company will utilize the geophysical blueprint of these workings to drill-test new, buried targets in the covered terrain. To refine these concealed targets for drilling, a comprehensive soil sampling program is planned, specifically targeting areas where subtle magnetic signatures of buried skarn are backed by coincident tungsten, copper, and molybdenum soil geochemistry.

An obvious feature from the ground magnetic survey is a strong dipolar magnetic signature. This is characterized by a sharp, high-intensity magnetic peak immediately adjacent to a pronounced magnetic low (see Figure 2). This distinct, high-gradient dipole is located proximal to the historical underground mine workings. This is considered a classic geophysical response for near-surface accumulations of massive magnetite and/or pyrrhotite. These are the primary skarn host minerals for the scheelite (tungsten), copper, molybdenite, and silver mineralization at Tungsten Ridge.

The detailed magnetic survey provides critical exploration information regarding skarn mineralization on the property, including:

1. Calibration: The distinct magnetic signature of skarn mineralization on the property has been successfully identified directly over the historic tungsten mine.

2. Plumbing System: A complex intersection of structures, potentially the plumbing system for mineralizing fluids, has been identified proximal to the known historic mine.

3. New Buried Targets: Importantly, several new magnetic targets have been identified within this complex structural system. These targets possess similar, though more subdued, magnetic signatures, which are interpreted as deeper, buried skarn mineralization. The most obvious new target is represented as a large magnetic low around the intersection of the three structures.

"Old projects like Tungsten Ridge and Talisman Tungsten become new opportunities with the introduction of either new economics or modern exploration techniques," stated Mark Kolebaba, President and CEO of Adamera Minerals. "In this case, we have both. We are applying modern exploration methods to these properties, at a time with severe global supply shortages and unprecedented tungsten prices. We are perfectly positioned to capitalize on this rare convergence of geological potential and market demand."

The significance of these exploration results is underscored by tungsten's critical role in global supply chains and the accelerating disruption of those chains.

About Tungsten, The Essential Metal

Tungsten's unique physical properties including extreme hardness, one of the highest densities of any metal, and the highest melting point of any metal make it an essential element in machining, electronics, aircraft manufacture, and military applications. Tungsten is used as a major component in projectiles (both bullets and missiles) and as a key component in armour plating for tanks and personnel carriers.

China dominates the supply side of the market, producing roughly 80% of tungsten yearly. In response to US tariffs, China has put severe export restrictions on tungsten products. Exports of Ammonium Paratungstate (APT), the primary product used as a manufacturing input worldwide, fell to zero in 2025. This has put severe constraints on the tungsten market. As of early April 2026, APT prices reached $3,150 per MTU (metric tonne unit, or 10 kilograms), up from about $300 per MTU in early 2025 (see Figure 3).

While Chinese export restrictions are blamed for the supply constraints, mined grades of tungsten at the large mines in China are believed to be dropping as well. These supply constraints may continue even if export bans are lifted. Given the sensitive nature and the military end uses, China is likely to prioritize domestic demand in any case.

High quality tungsten deposits are rare in the USA and timelines internationally for permitting and developing mines 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.
