Adamera Commences November Field Program at South Hedley Gold-Copper Project, British Columbia
Vancouver, November 12, 2025 - Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) ("Adamera" or the "Company") announces a field program is underway on the 100% owned South Hedley Gold-Copper Project in southern British Columbia. The campaign will apply both geochemistry and geophysics to expand and refine the Max and Glix prospects discovered earlier this year. The Company estimates that the program will be completed and reported on by mid December and it will be followed by the submission of a Notice of Work (NoW) drill application. The 18,714-hectare South Hedley property lies within an established mineral belt in southern British Columbia. The belt extends from the historic Nickel Plate gold mine at Hedley (more than 2.5 million ounces of gold)(1), to the Copper Mountain copper-gold-silver mine near Princeton (+1 billion pounds of copper reported since 2011)(2).
Mark Kolebaba, President and CEO of Adamera comments, "This field program represents another step towards drilling at South Hedley. The Max prospect continues to demonstrate the scale of a potentially significant gold-copper system. At the Glix prospect soil sampling has delivered samples with high gold, zinc and arsenic values. Both the Max and Glix prospects are advancing rapidly towards drill readiness."
Exploration Highlights
The South Hedley project is a greenfields gold project with little to no evidence of recent exploration.
At the Max Prospect, Adamera has outlined a strong gold-in-soil anomaly situated on the northwest portion of a 900 metre ("m") long copper in soil trend. Gold values exceed 1.0 g/t in multiple samples, including a discovery sample of 1,340 ppb (1.34 g/t) confirmed by fire assay and DetectORETM analysis. The target is associated with quartz-rhodonite veining and alteration. It remains open beneath younger volcanic cover. The gold anomaly is partially coincident with a deep, 500m long magnetic feature interpreted as the potential subsurface source. The November program will extend the soil grid beyond samples with anomalous gold values of 100 ppm and 283 ppm gold. A VLF-EM survey over part of the area is planned.

At the Glix Prospect, located about 10 kilometres from Max, Adamera has defined a coherent gold-in-soil anomaly with assays ranging from 24 to 4,283 ppb (4.3 g/t) gold with significant amounts of zinc and arsenic. The anomaly remains open in multiple directions and may be spatially associated with scapolite-altered calcareous rocks and pyrrhotite-arsenopyrite mineralization within the Hedley Formation. Follow-up work during the November program will include extending the soil grid with approximately 400 samples, prospecting for a bedrock source near the 4.3 g/t soil site and conducting detailed ground magnetic and VLF-EM surveys to help refine drill targets.

Adamera will report results from the soil sampling, VLF-EM surveys at both prospects, and the detailed magnetic work at Glix as data are received, compiled and interpreted.
About Adamera
Adamera Minerals Corp. is exploring for a high-grade gold and base metal deposit in Canada and USA. The Company is actively advancing projects with near-term discovery and development potential in Washington. Adamera is also reviewing options for its tungsten project in Washington State.
Gordon Gibson (P.Geo.), qualified person under NI 43-101, is an independent consultant that has reviewed and approved data associated with this release.
Samples were analyzed for gold at Activation Laboratories using 30 g fire-assay and in-house analysis using the DetectORE method. Such methods were described in previous releases by the company in 2025. The copper values in soil extending beyond the Max Prospect were determined by pXRF in house. Standards were inserted every 10th sample for QC/QA. Prior to pXRF analysis, the soil samples were sieved to -80 mesh size fraction.
