ADAMERA IDENTIFIES THREE DRILL TARGETS AT TALISMAN TUNGSTEN - TARGET ZONE EXTENDS UP TO 200 METRES BELOW HISTORIC WORKINGS

New geophysical modelling by Adamera Minerals Corp. at the Talisman tungsten property in Washington State has delineated three drill targets. The company applied 3-D inversion modelling of ground magnetic data, a methodology that adds a third dimension -- depth -- to determine the vertical extent of a magnetic source. This modelling has defined deep magnetic features interpreted to potentially be associated with tungsten-copper-silver mineralization.

The model shows a magnetic anomaly in proximity to the historic Talisman mine extends approximately 1,000 metres along strike and to depths of up to 200 metres below the workings. Based on the company's knowledge of the geology, its interpretation is for stacked skarn horizons below the deposit historically mined. That possibility is supported by the presence of surface mineralization at different elevations on the property, suggesting a substantially larger opportunity than previously recognized.

New 3-D modelling significantly expands historic mine target

The Talisman mine was a high-grade producer of tungsten, copper and silver plus or minus bismuth during the Second World War and the Korean War for U.S. military applications. Historic records report production grades averaging approximately 5 per cent copper, 103 g/t silver and 0.35 per cent to 1.0 per cent WO3.

Historic mine development of 600 metres is reported at Talisman. The only drilling recorded is from a series of short holes in the vicinity of underground stope development. No modern exploration drilling has been completed.

The new 3-D inversion indicates that the magnetic body associated with the historic mine extends nearly one kilometre along strike and continues to depths greater than 200 metres. Also, two additional undrilled magnetic targets have been identified elsewhere on the property.

"Historically, the mine exploited only a very small portion of what now appears to be a much larger mineralized system," stated Mark Kolebaba, president and chief executive officer of Adamera Minerals. "We have long known that the magnetic anomaly extended beyond the mine workings laterally. What this inversion confirms is that it also extends to depth below the historic workings. We have also identified two other undrilled anomalies, one centred on a surface sample of 0.33 per cent WO3. A third target lies below multiple high-grade copper-silver samples collected at the surface. Field crews are mobilizing this month to advance the targets towards drill testing."

Three priority drill targets

Adamera completed 3-D magnetic inversions to attain a better understanding of the geometry of the Talisman skarn system.

Target 1 -- mine zone (primary drill target)

All four inversions converge on a high-susceptibility body coincident with the historic mine area.

Key characteristics include:

• Approximately one kilometre of strike extent;
• Modelled depth extent exceeds 200 metres and remains open at depth;
• Historic mining occurred along the eastern flank of the anomaly, a favourable structural position commonly associated with high-grade replacement mineralization in skarn systems;
• Represents the highest-priority drill target on the property.

Target 2 -- southern discovery

Located approximately 720 metres south of the historic mine, a surface rock sample returned 0.33 per cent WO3 directly above a discrete magnetic anomaly.

Key characteristics include:

• More than 200 metres of modelled depth extent;
• No historic drilling, trenching or underground development;
• In tungsten skarn systems, scheelite precipitates where calcium-saturated carbonate fluids intersect tungsten-bearing magmatic inputs at structural gradient transitions. The coincidence of a high-grade surface sample with a depth-persistent magnetic body is consistent with a buried, potentially mineralized skarn.

Target 3 -- central-western anomaly

A third large magnetic body is modelled in the central-western portion of the property.

Key characteristics include:

• Strong dipolar magnetic response typical of magnetite-bearing skarn systems;
• Surface cover has limited historic prospecting and sampling;
• Elevated copper values have been identified in the area;
• A structural lineament links the anomaly to the mine zone target, suggesting a common hydrothermal source.

June, 2026, field program

Field crews are mobilizing this month to advance the targets toward drill testing. Planned work includes:

• Systematic soil and rock sampling along modelled structural corridors;
• Prospecting and geological mapping of magnetic gradient zones;
• Very low frequency and electromagnetics surveying to identify conductive sulphide-bearing structures and alteration halos commonly associated with copper-bearing skarns.

About the Talisman tungsten property

The Talisman tungsten property hosts a historic copper-silver-tungsten (plus or minus bismuth) skarn deposit in Washington State. Historic production records indicate grades averaging approximately 5 per cent copper, 103 grams per tonne silver and 0.35 per cent to 1.0 per cent WO3. The deposit formed where magmatic-hydrothermal fluids reacted with carbonate host rocks adjacent to intrusive bodies. No exploration drill holes have ever been completed on the property.
