Adamera Minerals Discovers Large Copper-Gold Anomaly at South Hedley Property

VANCOUVER, British Columbia, Adamera Minerals Corp., a leading exploration company in British Columbia, has announced significant findings from an induced polarization (IP) survey at its 100% owned South Hedley Copper-Gold Property in southern British Columbia. The survey, which resumed after wildfire risks eased, has identified a strong chargeability anomaly measuring at least 2.8 kilometers in width, with evidence of a full width up to 4 kilometers. This anomaly is centered on the Max target, located 18 kilometers east of the Copper Mountain mine and 18 kilometers west of the Nickel Plate gold mine.

The chargeability response of the 2D inversion suggests that the anomaly persists at depths greater than 325 meters. The Company interprets this as evidence of a buried sulphide system of considerable strength and extent. Surface volcanic rocks dominate the area, but a rock sample collected over the anomaly was identified as a sulphide-bearing dioritic intrusive rock, with copper values ranging from 200 to 2000 parts per million (ppm).

"The discovery of a large, undrilled copper-gold porphyry target of this size and strength, 18 kilometers from a producing copper mine in an established district, is a notable event," stated Mark Kolebaba, President and CEO of Adamera Minerals. "Our next steps will be to extend the IP survey, process soil and rock samples, and drill the resulting targets."

The IP survey, which is being conducted along 5 kilometers of lines spaced 400 meters apart, has shown chargeability increases below the volcanic rocks at the surface, suggesting a sulphide source at depth. Peak chargeability values of over 50 millivolts per volt (mV/V) have been measured in the field. A rock sample collected in August over the chargeability anomaly was described as a porphyritic diorite intrusive with sulphides, and preliminary analysis revealed anomalous copper values of 200 to 2000 ppm.

The South Hedley Copper-Gold Property is situated within the Quesnel Trough, a prolific porphyry copper-gold belt in south-central British Columbia. The Max target exhibits a classic porphyry geochemical response, with a 2 by 3 kilometer copper±gold-in-soil anomaly forming a horseshoe pattern around younger volcanic cover. Copper in soil reaches 1,450 ppm and gold reaches 1.34 grams per tonne (g/t), with the anomaly remaining open to the north, west, and possibly east. Approximately 1,800 additional soil samples have been collected to define the copper anomaly to the west and north.

Ground magnetic surveying has defined a 2 by 3 kilometer magnetic high within the soil anomaly, interpreted as a buried intrusive body with a modelled top at approximately 110 meters depth. The geophysical evidence of sulphides at depth, combined with surface evidence of a mineralizing system, supports the interpretation of a concealed sulphide system.

Due to the wildfire restrictions, the IP survey was suspended on August 11. However, wildfire risks and associated restrictions have eased with cooler temperatures and recent rainfall, allowing the survey to resume. Adamera has added drill sites to its drill permit application based on the current IP survey and the August 2026 program, with plans to continue IP surveying, complete rock sample analysis, process soil geochemistry, and conduct geological follow-up.

"We will continue to work to provide further evidence of a concealed sulphide system," Kolebaba added. "Our next steps are straightforward: extend the IP survey, process the soil and rock samples, and drill the resulting targets."

The results from the IP survey and the August 2026 program have provided a strong foundation for Adamera's exploration plans, with the potential to significantly advance the Max target and other exploration opportunities in the South Hedley Copper-Gold Property.
