Adamera Expands Tungsten Potential beyond the Talisman Mine
Vancouver, British Columbia – November 4, 2025–AdameraMineralsCorp. (TSX-V: ADZ;
OTC: DDNFF) (“Adamera” or the “Company”) announces a potentially significant new
occurrence of tungsten mineralization at its Talisman Property in Washington State. Rock
samples collected up to 720 metres (“m”) south of the historic Talisman Tungsten Mine returned
highly anomalous tungsten values ranging from 100 ppm to 2,600 ppm W.TheCompanywill

Surface sampling to date is early stage, and the continuity of tungsten-bearing zones requires
systematic evaluation. The semi-circular magnetic trend associated with mineralization (see
Figure 1) appears broadly to reflect a gently dipping stratigraphic unit apexing against surface
topography. If confirmed, this horizon could host a significant portion of the mineralization, with
its western extent likely concealed beneath overlying rocks.Toadvancethisinterpretation,the

Rock samples collected by Adamera near the Talisman Mine, topographically well above the
historic high-grade tungsten zones that contain 0.35% to 1.0% WO3(1), returned up to 80.5 ppm
W. Background tungsten levels in the area are typically below 5 ppm. By comparison, the newly
discovered samples with 100 ppm to 2,600 ppm W underscore the strength of the new results and
reinforce the potential for a much larger tungsten-bearing system on the property.

Ground magnetics and Modeling
Skarns typically contain magnetite and or pyrrhotite, making magnetic surveying a valuable
exploration tool. A ground magnetic survey performed by Adamera shows a strong dipolar
magnetic signature over the Talisman Mine. This response is consistent with a typical magnetic
response for skarn-style mineralization. This signature extends for hundreds of metres beyond
the historic mine workings. A second larger and parallel strongly dipolar anomaly has been
identified approximately 600m south of the mine. This anomaly is partially coincident with
samples containing high tungsten in outcrop, further supporting the presence of a target zone
with significant dimensions.
Adamera is preparing a detailed 3-D geological model integrating geochemical, magnetic, and
structural data to determine the possible continuity between the mine and the new tungsten-
bearing zones. This will guide exploration targeting.

The Historic Talisman Tungsten Mine
The Talisman Mine exploited two high-grade zones with semi-massive and disseminated
sulphides. It produced ore containingcopper, lead, zinc, tungsten, silver and minor gold. It is
regarded as a stratabound contact metamorphic skarn deposit. Sulphide minerals include
bornite, chalcopyrite, sphalerite, galena and scheelite as the tungsten mineral.

Development is reported to comprise over 600m of shafts, crosscuts and drifts. Many previously
undocumented prospects are also evident on the property, far from the Talisman Mine itself.The
mine consists of a 21m vertical shaft, two flat-lying stopes developed along a 170m long adit.
The tungsten component of the deposit became significant during/after WW1.Records are
incomplete but at least 521 tons of high-grade ore was mined around 1915 and 2000 tons in
1952. In 1948 approximately 54 tons of ore was mined that averaged 20% lead, 11% zinc, and 75
g/t silver.The ore zones were up to 3.7m thick. How much of the mining history was for base
metal extraction versus tungsten is not documented.
The Copper-silver Target
Adamera has developed a coper-silver target on the property. It is interpreted to be sediment-
hosted, polymetallic, strata bound sulphide mineralization that may or may not be related to the
tungsten deposit. Rock sampling by the Company has identified copper and silver in outcrop
extending 1.5 kilometres southwest from the mine area. That mineralization is intermittently
coincident with tungsten anomalies. The association of these metals indicates may represent
multiple mineralizing events or metal zoning within the same hydrothermal system. Copper-
silver mineralization is also evident on a northwesterly tend that intersects the southwest
tungsten trend. Follow up prospecting and sampling is warranted.
About Adamera
Adamera Minerals Corp. is exploring for a high-grade gold deposit in Canada and USA. The
Company is actively advancing projects with near-term discovery and development potential in
the Republic and Laurier areas of northeastern Washington.
Jim Ebisch (P.Geo.), qualified person under NI 43-101, is an independent consultant that has
reviewed and approved data associated with this release. Rock samples were analyzed at
Activation Laboratories from 2012 to 2022. Such results with the exception of the tungsten
values were previously released.
