Adamera Identifies Gold-Copper Porphyry Target at South Hedley,

B.C. - Drilling Application Submitted

Vancouver, British Columbia – February 18, 2026 – Adamera Minerals Corp. (TSX-V: ADZ;

OTC: DDNFF) (“Adamera” or the “Company”) has identified a large-scale copper-gold target on

its 100% owned, South Hedley Copper Gold Project. The target has the potential to transform the

Max prospect into a district-scale copper-gold porphyry opportunity.

The project is located between the historic Nickel Plate gold mine and the active Copper

Mountain mine in southern B.C. (See Figure 1). A Notice of Work has been submitted to

facilitate induced polarization surveys and a subsequent drilling program later in 2026.

Adamera previously reported on the Max and Glix Prospects at South Hedley (see News

Releases dated Nov. 12, 2025, Nov. 26, 2025 and Dec.16, 2025). To date, work has primarily

consisted of geophysical surveying, geochemical sampling and prospecting that defined two gold

and base metal targets. Combining the data from the Max prospect with surrounding data

indicates that Max falls on the edge of a horseshoe-shaped geochemical anomaly (See Figure 2).

Within the horseshoe-shaped feature is a 2 square kilometre magnetic anomaly that suggests a

possible buried diorite intrusion and potentially a large-scale mineralized system (see Figure 4).

Geological mapping indicates that the target appears to be covered by a barren volcanic tuff.

“The coincidence of strong copper-gold geochemistry and a 3-D inversion magnetic feature

within a copper-gold prospective corridor is precisely what we look for in a tier-1 exploration

target,” stated Mark Kolebaba, President and CEO of Adamera Minerals. “We have moved

beyond the isolated ‘Max Prospect' to identifying a 2 square kilometre target with a geophysical

signature suggestive of a buried dioritic intrusive. We will now apply more detailed prospecting

and an induced polarization survey to define the distribution of sulphides beneath the barren

tuff. This marks a technical turning point for the project.”

The 20,000-hectare South Hedley property is situated within the Quesnel Trough, which is a

fertile crustal-scale structure hosting several major deposits such as New Afton, Highland

Valley, and Copper Mountain. The Max anomaly has a north-northwest trend, aligning with the

regional magmatic axis that controls mineralization at the nearby Copper Mountain and Nickel

Plate camps (See Figure 1).

Figure 1 — South Hedley is located between the Nickel Plate Gold Copper Skarn and Copper Mountain Mine and

falls within one of Canada’s most productive mineral corridors, the Quesnel Trough regional porphyry belt which

contains several other copper-gold deposits including New Afton, Highland Valley, Craigmont and B renda.

Technical Interpretation

Below are a series of maps and observations that led to this current interpretation.

• Geochemical Zonation & Intensity: The survey defined a marked zonation pattern typical of

porphyry-style copper-gold systems. Copper values reach up to 1,450 ppm, while gold values peak

at 1.61 g/t (1,610 ppb). The gold anomalies are spatially associated with copper highs but display a

more structurally focused distribution along internal corridors and margins of the broader copper

footprint.

Figure 2 - Integrates gold (red) and copper (green) soil geochemistry to define a 3 kilometre horseshoe-

shaped anomaly consistent with the outer expression of a large hydrothermal system. The data reveals a

zonation pattern typical of a porphyry system. The Max Prospect, situated on the southwest margin,

represents the strongest coincidence of these metals, identifying a high -priority target area within the

broader footprint.

• Ground Magnetic Data: Total magnetic Intensity (TMI) ground survey data shows high

frequency responses over the area of increased volcanic cover thickness (see Figure 3). A

3D inversion of the data reveals a persistent magnetic high feature that becomes coherent at

depths below 110 metres. This feature is approximately 1 X 2 kilometers in size and is

interpreted as a possible buried diorite intrusion, which is a recognised source for

mineralization in the Hedley and Copper Mountain districts.

Figure 3 – Ground magnetic data – TMI shows shallow high frequency magnetic high response of near surface rocks

in the area in relation to the copper gold in soil anomalies. The black dash line outlines the general extent of the

copper (white) and gold (orange) in soil. Figure 4. below shows inversion data whereby the high frequency shallow

response is essentially stripped away to expose underlying lower frequency deeper response.

Figure 4 – Presents the ground magnetic inversion at a depth of 160 m and shows a coherent magnetic high feature

measuring 1 x 2 km (outlined by solid black line). It is surrounded by the copper (white) and gold (orange) soil

anomaly (black dash line) and is interpretated as a possible porphyry intrusion.

Target Model: The strongest gold and copper anomalies are at the margins of this buried

magnetic high, suggesting a classic skarn or porphyry contact setting. The Company interprets

the observed "horseshoe" geochemical anomaly as the outer expression of a “blind” intrusive

system. The magnetic feature outlined by a black line in Figure 4 is the target hydrothermal

system.

Expansion of the Max Prospect

The Max Prospect, which is a recent discovery of high gold and copper values in soil and rock, is

now interpreted as the exposed southwest margin of a larger copper – gold system. The high

gold and copper values are situated in a steeply incised valley that suggest underlying

mineralized rocks associated to an intrusive are exposed at lower topographic levels.

Rocks with alteration and sulphides (see Photo 1 below) located below the barren volcanic tuffs

have been identified during soil sampling. The distribution of these rocks will be mapped and

sampled once the snow melts in the spring.

Next Steps

The Company has defined a clear path to drill testing:

1. Drill Permitting: A Notice of Work (permit application) for drilling has been submitted.

This diamond drill program will test high-priority target areas.

2. Geophysics: An Induced Polarization (IP) survey Notice of Work (permit application) has

been submitted. This survey will map chargeability and resistivity at depth, aiding in

defining the distribution of sulphide mineralization and alteration within the system.

3. Expanded Geochemistry: Further analyses on existing samples and infill sampling surveys

will be completed in order to assist in vectoring within the mineralised system.

In addition to the expanded South Hedley target, the Company has identified a second prospect

on the property called the Glix Prospect. This target is located approximately 15 kilometres from

the Max target. Based on recent geological, geochemical and geophysical data. the Glix target is

considered to be comparable to a gold bearing skarn environment, similar to the Nickel Plate

Mine. Results from the November program are expected soon.
