Adamera Advances Targeting on the South Hedley Gold

Property In British Columbia

Vancouver, British Columbia – August 14, 2025 – Adamera Minerals Corp. (TSX-V: ADZ; OTC:

DDNFF) ("Adamera" or the "Company") announces it has advanced targeting on its 18,714-hectare South

Hedley Gold Property in B.C. Detailed soil sampling over the Max Prospect area has identified a zone

with consistently anomalous gold values. Results from 46 soil samples collected last week, extended the

gold anomaly further southeast and confirms a cut-off to the northwest. The anomaly remains open to the

southeast where it becomes covered by an extensive cover of talus. Based on the data at this time, the

exploration target may have a potential strike length of 500m.

Soil samples collected much further to the southeast also contain anomalous gold. One sample, located

approximately 500 metres (“m”) southwest of the Max Prospect, contains 142 ppb gold (determined by

fire assay at Activation Lab). Inversion of ground magnetic data over the immediate area shows a

magnetic feature within a fault bound wedge that is coincident with the anomalous soils (20 to 1,300 ppb

gold). The magnetic feature trends northwest-southeast for approximately 500m from the Max Prospect to

the sample with 142ppb gold. This magnetic feature supports the northwest cut-off of gold in soil samples

at the Max Prospect. See Figure 1 below.

Figure 1. Magnetic inversion data over an area that includes the Max Prospect (shown as “Max” on the map). The three target

symbols over the magnetic feature represent soil samples with anomalous gold. The most northerly target symbol is the Max

Prospect, the two targets to the south are single soil anomalies that require immediate follow up. The three maps show the

magnetic target becoming increasingly more cohesive with depth. This magnetic feature is fault bound (fault = heavy black

lines) along the NE and is coincident with soil samples with anomalous gold. All three areas with soil samples are at an elevation

of approximately 1,400 m.

Volcanic tuff is a dominant lithology capping the area. These tuffs are thought to be younger than the

rocks that typically host gold mineralization in the area and as such are considered not to be prospective

for gold. This is substantiated by the fact that our prospecting has found no old mines/prospects in this

rock type. Soil samples with gold, evidence of quartz veining, presence of sulfides and rock alteration are

restricted to areas that are topographically below the tuff. Therefore, it is the underlying “masked” rocks

that have potential. Figure 2 is a graphic insight into our current exploration concept. The magnetic

inversion data corroborates a possible primary gold source at depth.

“We are making significant advances at the South Hedley Project as we push to expand the Max Prospect

to the southeast. In fact, our data is suggestive of a target with potential strike length of 500m. The

discovery of previously unknown gold apparently “leaking” from beneath an overlying tuff explains why

the area has newly identified potential yet no evidence of previous exploration and/or mining. If we were

not so close to a major gold camp we perhaps would have shrugged off the initial evidence we obtained.

Follow up work will be immediate” says Mark Kolebaba, President and CEO of Adamera Minerals.

A total of 96 follow up soil samples were collected over the area in mid to late July and early August. The

samples were analysed using the DetectORETM method. Several of these samples yielded highly

anomalous gold results ranging from an approximated 100 to 1,300 ppb* gold. Sites with soil samples of

100 ppb* to greater than 1,000 ppb* gold are targeted for prospecting. Quartz veining and sulfide

(arsenopyrite) bearing rocks have been identified and sampled at these localities. Results for several rock

samples are pending.

A crew is scheduled to arrive on site at the end of the week. An exploration priority will be to collect

additional soil samples over the area where a previous soil sample yielded 142 ppb gold. This area is

located near the southeast end of the Max Prospect magnetic target which is approximately 500m from

the Max Prospect. In addition, several other reconnaissance soil samples with anomalous gold that are

located in topographic low areas on the property will be reviewed and followed up with respect to the

conceptual exploration model mentioned above.

The Max Prospect is located in the northwest portion of the 100% owned property, between Whistle and

Smith Creeks (see Figure 3). The site is unexplored, having been identified from reconnaissance soil

sampling carried out by the Company. One soil sample yielded 1,340 ppb or 1.34 g/t gold. The prospect is

coincident with newly discovered quartz-rhodonite veining in contact metamorphosed volcanic rocks. It

also coincides with a prominent magnetic anomaly and a structural/topographic lineament that extends for

several hundred metres.

Figure 2. Conceptual Model for Exploration at the Max Prospect. The concept considers an overlying volcanic tuff

“cap” that is younger than the underlying mineralized rocks of the area. Soil samples collected above the tuff would

be barren (marked by “-”) and soil samples collected beneath the tuff and over the underlying mineralized rocks

exposed in topographic lows would be more likely to contain gold (marked by “+”).

Approximately 2.5 million ounces of gold** was reportedly produced in the Hedley Gold Camp. The

Max Prospect is located less than 10 kilometres from Barrick Gold Corp’s past producer, the Nickel Plate

Mine.

Soil samples were analyzed in-house using the DetectORETM method for gold, a proprietary process developed by

Portable PPB in Australia that allows for rapid gold analysis at ppb levels using a pXRF. The method uses a

rigorous QA/QC process whereby a standard rock sample of known gold content is inserted every 30 samples at the

preparation step. This sample is later analysed by the pXRF along with additional control samples that are tested

every 20 analyses. The pXRF is fully automated and can analyse up to 180 samples per run. Each sample run using

the pXRF is initiated by testing 5 control samples, if any samples do not pass the standard’s specifications, the XRF

is immediately calibrated.

*The gold content of the discovery soil sample with 1,340 ppm gold was determined by fire assay of a 30-gram

sample with atomic absorption finish at the Activation Laboratory in Kamloops. Adamera resampled the same site

and analyzed 400 grams of soil using the DetectORE TM method which yielded a comparable 1,361 DetectORE units

representing a calculated ppb value.
