Vancouver, British Columbia – July 9, 2025 – TheNewswire - Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) ("Adamera" or the "Company") announces it 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 (see Video.) 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 CEO 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.
-
Located in a proven high-grade district: +4 million ounces of gold (avg. grade 23 g/t) and +20 million ounces of silver (avg. grade 121 g/t). Flag Hill South lies ~2 km south of the historic Golden Promise Mine.
-
Strong analogues to nearby producers: host rocks and vein textures are consistent with known mines.
-
2024 drilling demonstrated increasing grade and width with depth.
-
Detailed magnetic and geochemical surveys identified shallow untested vein targets and a magnetic anomaly (~140m x 170m) at 80–85 metres depth, potentially representing a broad hydrothermally altered zone with coalescing veins.
The 2024 drill campaign targeted a central epithermal vein from two pads, completing three holes:
-
FHS24-01: 1.1 m @ 0.3 g/t Au, 1.0 g/t Ag (Elevation 918.5m)
-
FHS24-02: 2.0 m @ 3.0 g/t Au, 10.8 g/t Ag (Elevation 877m)
-
FHS24-03: 2.2 m @ 1.8 g/t Au, 71.2 g/t Ag (Elevation 904m)
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 February 27,2025).
Geophysical Survey & 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 12.5m 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 140m x 170m ovoid magnetic low was detected at a depth of 80–85m. This broad zone is interpreted to represent hydrothermal alteration. Potentially multiple veins coalesce, forming a larger exploration target than previously known.
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:
-
Several linear magnetic lows with no outcrop are geochemically anomalous, indicating potential for blind veins.
-
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.
-
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 175m.
-
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
Adamera Minerals Corp. is exploring for a high-grade gold deposit near Republic Washington. This area has reportedly produced 8 million ounces of gold averaging 14.5 g/t. Adamera is the dominant regional explorer in the area.
Gordon Gibson (p. Geol), qualified person under NI 43-101, has reviewed data associated with this project.
Soil samples were analyzed in-house using the DetectORETM method for gold and silver, with additional elements determined by standard pXRF.
