ADAMERA FINALIZES DRILL PLANS AT FLAG HILL SOUTH, WASHINGTON STATE

Adamera Minerals Corp. has finalized drill plans for its Flag Hill South gold-silver property in Washington State. The summer drill program builds on the company's 2024 drilling activities that identified increasing gold-silver grades and vein widths with depth.

In addition to drilling on the property, Adamera also completed detailed ground magnetic and soil sampling surveys. The survey data resulted in the identification of multiple near-surface epithermal vein targets. Inversion processing of the ground magnetic survey data unexpectedly identified a large magnetic low anomaly at depth. This anomaly is supported by soil geochemical data.

"Flag Hill South is located in a high-grade gold-silver epithermal system," said Mark Kolebaba, president and chief executive officer of Adamera Minerals. "Our recent work has defined multiple vein targets and a new large-scale deep-seated anomaly. I'm particularly encouraged that both geophysics and surface geochemistry support the potential for a significant discovery at depth."

The Flag Hill South property lies within the prolific Republic gold district. The deposits are all epithermal in character including the well-known Knob Hill and Golden Promise systems. The property hosts epithermal-style quartz veins and alteration characteristic of the high-grade deposits in the district. There has been significant historic production immediately north, east and west of this property.

Project highlights

• Located in a proven high-grade district: plus four million ounces of gold (average grade 23 grams per tonne) and plus 20 million ounces of silver (average grade 121 g/t). Flag Hill South lies approximately two kilometres south of the historic Golden Promise mine.
• Strong analogues to nearby producers: host rocks and vein textures are consistent with known mines.
• Two thousand twenty-four drilling demonstrated increasing grade and width with depth.
• Detailed magnetic and geochemical surveys identified shallow untested vein targets and a magnetic anomaly (approximately 140 m by 170 m) at 80 to 85 metres depth, potentially representing a broad hydrothermally altered zone with coalescing veins.

2024 drill program and results

The 2024 drill campaign targeted a central epithermal vein from two pads, completing three holes:

• FHS24-01: 1.1 metres at 0.3 g/t Au (gold), 1.0 g/t Ag (silver) (elevation 918.5 m);
• FHS24-02: 2.0 m at 3.0 g/t Au, 10.8 g/t Ag (elevation 877 m);
• FHS24-03: 2.2 m at 1.8 g/t Au, 71.2 g/t Ag (elevation 904 m).

These results indicate vein width and gold/silver grades increase with depth, which is consistent with other deposits in the region. Also increasing with depth is tellurium and selenium which are proven reliable pathfinders for high-grade gold and silver in the district (see release dated Feb. 27, 2025).

Geophysical survey and magnetic inversion

Magnetic susceptibility measurements of drill core from the property in 2024 shows a significant decrease in magnetic susceptibility associated with the veins due to hydrothermal alteration. This prompted the company to conduct a ground magnetic survey to identify other potential veins on the property. A detailed survey on 12.5 m spaced lines identified several linear magnetic lows, some of which are associated with known veins. Other magnetic lows features are unresolved due to a lack of outcrop. These are potentially related to blind veins.

Inversion modelling of the ground magnetic data was conducted to gain a better understanding of the orientation of the veins. A 140 m by 170 m ovoid magnetic low was detected at a depth of 80 to 85 m. This broad zone is interpreted to represent hydrothermal alteration. Potentially multiple veins coalesce, forming a larger exploration target than previously known.

Soil geochemistry program

In 2025, a soil sampling program was completed to refine the magnetic lows as gold-silver drill targets. A total of 298 samples were collected across the property. Three key observations include:

1. Several linear magnetic lows with no outcrop are geochemically anomalous, indicating potential for blind veins.
2. The broad magnetic low at depth has silica and iron responses in the soils. Silver in soil occurs peripherally to the modelled magnetic low at depth.
3. Gold and silver soil anomalies extending beyond known exposed veins, suggest longer strike lengths and greater continuity than previously expected.

Next steps: 2025 drill program

Adamera's 2025 plan:

• Several deep holes are planned to intersect the central vein at depth below holes FHS24-02 and FHS24-03. The planned depth of vein intersection is approximately 175 m.
• Test near-surface vein targets defined by combined magnetic lows with gold and/or silver in soil.
• Drill into the large magnetic anomaly at depth.

About Adamera Minerals Corp.

Adamera is exploring for a high-grade gold deposit near Republic, Wash. This area has reportedly produced eight million ounces of gold averaging 14.5 g/t. Adamera is the dominant regional explorer in the area.

Gordon Gibson (PGeol), qualified person under National Instrument 43-101, has reviewed data associated with this project.

Soil samples were analyzed in-house using the DetectORE method for gold and silver, with additional elements determined by standard pXRF.
