Magnetic Survey Significantly Expands Skarn Potential at Adamera's
Tungsten Ridge Property
Vancouver, British Columbia – 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 significantly expand the property's
prospective skarn/tungsten mineralization footprint beyond the historical underground mine
workings. These findings will also refine the design of an upcoming geochemical survey across
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 leverage the geophysical blueprint of the
historical workings to drill-test newly identified, buried targets within the covered terrain. To
further refine these concealed targets ahead of 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, very high density, and the
highest melting point of any metal make it an indispensable element in machining, electronics,
aerospace manufacturing, and wide range of military applications. Tungsten is used as a major
component in projectiles (such as 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.
