Vancouver, British Columbia, February 27, 2025 – TheNewswire – Adamera Minerals Corp. (“Adamera& or the “Company&) (TSX-V: ADZ; OTC: DDNFF) announces results from its first three drill holes at the Flag Hill South property in Washington State. The results indicate a marked increase in gold-silver grades and vein width with depth supporting our interpretation that the property holds viable potential for a high-grade epithermal system, similar to the nearby Knob Hill Gold Mine.

Drill Results Include:

• FHS24-01: 1.1m @ 0.3 g/t gold and 1.0 g/t silver – Elevation 918.5m

• FHS24-02: 2.0m @ 3.0 g/t gold and 10.8 g/t silver - Elevation877m

• FHS24-03: 2.2m @ 1.8 g/t gold and 71.2 g/t silver - Elevation 904m
  Elevation in metres refers to the intersection point of the eastern margin of the vein

This clear trend of increasing grades and vein thickness as drilling progresses is comparable to the nearby historic Knob Hill and Golden Promise mines, which together have produced over 4 million ounces of gold and 15 million ounces of silver. The Knob Hill deposit was mined to a depth of 365m.

“We are excited by the early results from our Flag Hill South property. An increase in grade with depth and the appearance of microbanding, typical of low sulphidation epithermal systems, is what we wanted to see,& says Mark Kolebaba, CEO of Adamera. “This drilling has provided vital geochemical and geological evidence that allows us to compare the property with the high-grade Knob Hill and Golden Promise deposits, approximately 2 km away. The higher silver, selenium and tellurium values with gold is significant and gives us clear exploration direction and confidence in the potential of the property.&

Geological and Geochemical Insights:

The Flag Hill South property is located approximately two kilometres from the Knob Hill and Golden Promise mines and fourteen kilometres from The Kinross Kettle River Mill. The historic Knob Hill and Golden Promise mines are low sulphidation epithermal deposits reportedly containing an average grade of 23 g/t gold. In outcrop and drill core the Flag Hill South veins exhibit textural (Figure 1) and geochemical features that suggest the veins are relatively high-level in the system above the boiling zone that is capable of producing the bonanza grades of the nearby producers.

Key findings from the 2024 drilling program include:

1. Increased Grade and Vein Width at Depth: The second and third drill holes showcase the potential for higher-grade mineralization as depth increases. The vein was intersected in drill holes 2 and 3, at 80 and 70 vertical metres respectively, approximately twice as deep as the
   vein intersection in the first hole which was at 38 vertical metres. The vein intersections in hole 2 and 3 are essentially twice as thick and contain more than double the gold grade as the vein intersected in hole 1.
   

2. Geochemical Pathfinders: The vein intercepted in the third hole collared 111.25m south of the first two holes reports higher selenium and tellurium values. Up to 40 ppm selenium and 100ppm tellurium coincide with significantly higher silver (up to 125 g/t). The increased presence of these and the depletion of sulphur aligns with the geochemistry of Knob Hill.
   

3. Multiple Veins: There are numerous other veins on the property that remain untested. Deeper drilling will intersect these veins. Generally speaking, in a given epithermal system all the veins will have a boiling zone at approximately the same elevation. Thus, testing the additional veins is now warranted.

Future Plans:

The Flag Hill South drilling will focus on drilling deeper to test the continuity and grade of the veins at depth. The next planned drill hole will be collared significantly east of the current drill pads and drilled westward toward the vein. At least 5 or more other veins are expected to be intersected as the drill advances to the main target at an estimated depth of 180m below surface. In addition, the Company will use detailed ground magnetics to map the numerous and complex veining structures evident on the property.

Analytical Procedures:

BTW size drill core was recovered, logged and split using a rock saw. One half of the core was submitted to Activation Laboratories for crushing, pulverizing and analysis. Gold content was determined by fire assay with AA finish. Multi-element analysis was completed using aqua-regia with ICP-AES finish. Additional analysis by PhotonAssay is currently underway.

The Company is awaiting overlimits on a sample that reported >100 ppm silver. For the purpose of this release, the sample with >100 ppm silver was analyzed using an Avanta pXRF using a 3-beam method with 50 KV. This provides a reliable analysis for silver at this concentration.
