ADAMERA RECEIVES INVERTED IP DATA FOR THE MAX COPPER-GOLD TARGET AS SURVEYING OF THE LAST LINE IS UNDERWAY, SOUTH HEDLEY PROJECT, BRITISH COLUMBIA

Adamera Minerals Corp. has received inverted induced polarization (IP) chargeability data for the first eight survey lines, L1400 to L4200, at the Max copper-gold target on its South Hedley project, near Hedley, B.C. Line L4600 has been surveyed and surveying of the last line, L5000, is under way.

The inverted data show a continuous body of high chargeability extending from L1800 to L4200, with inverted values of up to 77 millivolts per volt (mV/V). The anomaly weakens on L1400 in the west and line L4600 shows weakening in the east. Once L5000 is complete, the chargeability anomaly is expected to measure in the range of three to four kilometres (km) north to south and 3.2 to 3.6 km east to west. On some survey lines, the chargeability remains open to the north.

"The inverted data confirm a large, continuous chargeability body at Max and we are now close to defining its full extent," said Mark Kolebaba, president and chief executive officer of Adamera. "The chargeability sits with copper and gold in soils, and a buried magnetic intrusive target, three independent lines of evidence pointing to a possible porphyry system under cover. The anomaly is mostly closed off to the west and we expect L5000 to close it off to the east. We will then have a complete IP data set to combine with the magnetics and this year's soil results to select additional drill targets."

Inverted IP results, lines L1400 to L4200

The survey uses a pole-dipole array on north-south lines spaced 400 metres apart. Nine lines have now been completed, from L1400 in the west to L4600 in the east. The inverted stacked sections include lines 1400 to 4200:

• Continuity: High chargeability is continuous from L1800 to L4200, with multiple high-chargeability cores. The strongest and broadest response is on the central lines, L2200 to L3400.
• Southern margin: The anomaly is closed to the south on all lines. On L3800, the southern margin is sharp, which may reflect a structural or lithological contact.
• Northern limit: The northern extent of the anomaly is less clearly defined. Chargeability remains open to the north on L2200 and L3400, and weakens toward the north ends of L2600, L3000, L3800 and L4200. The northern extension on L2200 will be followed up with soil sampling, prospecting and mapping.
• Western limit: On L1400, the anomaly is present at depth but substantially weaker. This is consistent with ground magnetics, which shows a clear structural contact.
• Eastern limit: L4200 remains strongly anomalous. Preliminary field readings from L4600 show anomalous chargeability that is weaker than on the lines to the west.

Next steps

Lines L4600 and L5000 will be submitted for inversion. The full IP data set will then be combined with ground magnetics and the results of approximately 2,000 soil samples collected at Max in 2026. Soil sample results are pending. Drill permit applications for the Max and Glix targets were submitted in February, 2026.

South Hedley project

South Hedley is a copper-gold property of approximately 25,000 hectares between Princeton and Hedley, B.C., just south of B.C. Highway 3. It lies within the Quesnel trough, approximately 18 km from Hudbay Minerals Inc.'s Copper Mountain mine. Previous soil sampling at Max returned up to 1,450 parts per million (ppm) copper and 1.34 grams per tonne (g/t) gold. Magnetic modelling indicates a buried intrusive body starting at approximately 110 metres depth.

Martin St. Pierre, PGeo, a qualified person as defined by National Instrument 43-101 and a consultant to the company, has reviewed and approved the technical content of this news release. Inverted chargeability values are model results that depend on the inversion parameters used and they are not directly comparable with apparent (field) values reported previously. Results from L4600 are preliminary field readings that have not been inverted. IP chargeability indicates the presence of polarizable minerals, which may include sulphides that do not contain copper or gold, and is not indicative of grade, continuity or economic potential. Mineralization at the Copper Mountain mine is not necessarily indicative of mineralization on the South Hedley property.
