Adamera Minerals Corp. Completes Additional IP Lines at Max Copper-Gold Target, Detects Anomalies

VANCOUVER, BRITISH COLUMBIA — September 16, 2026 — Leads & Copy — Adamera Minerals Corp. announced the completion of three additional induced polarization (IP) lines at its Max Copper-Gold Target on its 100%-owned South Hedley Property in southern British Columbia. Each line surveyed to date has detected a chargeability anomaly, with Line L2200 showing anomalous chargeabilities in the vicinity of the highest copper and gold values found in soil samples at Max, which include 1,450 ppm copper and 1.34 g/t gold.

The chargeability anomaly spans 3 to 4 kilometers in width along individual north-south survey lines and has a strike length of 1.6 kilometers to date. The five completed lines—L3000, L2600, L2200, L1800, and L1400—are spaced 400 meters apart. The survey employs a pole-dipole array with 100-meter dipole spacing over 5 km lines.

The primary goal of the IP survey is to delineate the boundaries of the chargeability anomaly and the extent of the Max copper-gold target. Results from the fifth line, L1400, indicate a weakening chargeability to the west, aligning with predictions from ground magnetic data and regional geology. Adamera interprets this as a potential western limit of the anomaly. The anomaly remains open to the east, and the survey will proceed east of L3000, commencing with L3400.

The correlation between chargeability and copper-gold in soil was first observed on the initial survey line and has now been identified across a significant portion of the strike length defined so far. This correlation is partial due to the discontinuous nature of soil sampling completed to date. An additional 2,000 soil samples were collected during the 2026 program to enhance coverage along the IP survey lines, with results 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 Max Copper-Gold Target is situated within the Quesnel Trough, a porphyry copper-gold belt in southern British Columbia, approximately 18 km from the producing Copper Mountain mine and 18 km from the historic Nickel Plate gold mine. The target exhibits a 3 by 2 km copper±gold-in-soil anomaly in a horseshoe pattern, a geochemical signature characteristic of mineralized porphyry systems. This anomaly remains open, and the 2026 soil sampling aims to define its extent.

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

IP data suggest the chargeability response extends below 300 meters depth and appears to originate beneath the volcanic cover. Coincident resistivity data show the anomaly is hosted in moderate-to-elevated resistivity rock, a pattern consistent with disseminated sulphides in resistive host rock.

Future steps include shifting the IP survey east of L3000 to close off the anomaly eastward, inverting new data from lines L2200, L1800, and L1400, and processing the 2,000 soil samples collected in 2026. Additional samples are planned for the north end of L2200. The company has also submitted a drill permit application to test the IP chargeability anomaly and other resulting targets.

The South Hedley property, near Princeton, British Columbia, now covers over 24,000 hectares following recent claim applications. The property hosts two advanced targets: the Max Copper-Gold Target and the Glix gold skarn target. Drill permit applications for both were submitted in February 2026.
