Adamera expands Max copper-gold target at South Hedley

Vancouver, British Columbia – TheNewswire - September 16, 2026 – Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) (“Adamera” or the “Company”) announces it has completed three additional induced polarization (“IP”) lines at its Max Copper-Gold Target on its 100%-owned South Hedley Property in southern British Columbia. Every line completed to date has detected the chargeability anomaly. On line L2200 anomalous chargeabilities are present in the immediate vicinity of the highest copper and gold in soil values returned at Max to date, which include 1,450 ppm copper and 1.34 g/t gold.

The chargeability anomaly reaches 3 to 4 kilometres (km) in width along individual north-south survey lines and 1.6 km of strike, to date. The five completed lines, L3000, L2600, L2200, L1800 and L1400, are spaced 400 metres apart. The survey is being conducted along 5 km lines using a pole-dipole array at 100-metre dipole spacing.

The objective of the IP survey is to define the limits of the chargeability anomaly and the extent of the Max copper-gold target. Results from the fifth line, L1400, show chargeability weakening to the west, as predicted by the ground magnetic data and regional geology. Adamera interprets this as a possible western limit of the anomaly. The anomaly remains open to the east, and the survey will move east of L3000, starting with L3400.

The coincidence of chargeability and copper-gold in soil was first reported on the initial survey line and is now carried across much of the strike length defined to date. The coincidence is partial, as the soil sampling completed to date is not continuous. An additional 2,000 soil samples were collected during the 2026 program to provide more complete coverage along the IP survey lines. Results for the 2026 soil samples are pending.

“Identifying up to 1,450 ppm copper and 1.34 g/t gold in soil at the Max Target is the point at which we first recognized a possible significant copper-gold target on the property. The coincidence of anomalous chargeabilities with the geochemistry is strong evidence consistent with sulphide mineralization. The anomaly has grown in area with every line we have completed, and we have an estimated 3 km by 1.6 km anomaly with the eastern side currently unbound. This target has scale,” said Mark Kolebaba, President and CEO of Adamera.

The Target Characteristics

Proven belt: The Max Copper-Gold Target lies within the Quesnel Trough, a porphyry copper-gold belt in southern British Columbia, and is located 18 km from the producing Copper Mountain mine and 18 km from the historic Nickel Plate gold mine near Hedley.

Characteristic porphyry geochemical response: A 3 by 2 km copper±gold-in-soil anomaly at Max forms a distinctive horseshoe pattern, a geochemical signature consistent with mineralized porphyry systems. The copper anomaly remains open, and the 2026 soil sampling is intended to help determine its extent.

A buried intrusive source: Recent ground magnetic surveying has defined a 3 by 3 km magnetic high coincident with the copper-gold soil anomaly, interpreted as a buried intrusive body with a modelled top at approximately 110 metres depth beneath the volcanic cover. Small outcrops of diorite-composition intrusive rocks carrying anomalous copper have been identified within the magnetic feature near zones of chargeability.
