Vancouver, British Columbia – TheNewswire - September 8, 2026 – Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) (“Adamera& or the “Company&) announces it has filed applications for the Bromley claims, adding over 4,700 hectares contiguous to the Company&s 100%-owned South Hedley Property. This newly staked ground expands the northwestern edge of the property 12 kilometres (km) westward, connecting to the eastern claim boundary of Hudbay Minerals Inc.&s Copper Mountain mine claims.

The Bromley claim applications cover an approximately 12 x 4 km corridor concealed beneath a sequence of younger volcanic rock, where Adamera has identified distinct magnetic features. This area is positioned along an approximately 40 km east-west trend that Adamera interprets as a structural and metallogenic corridor connecting the producing Copper Mountain mine to the historic Nickel Plate mine near Hedley, British Columbia. The Company&s Max Copper-Gold Target is positioned within this corridor.

“This staking reflects our broader vision for the district. The locations of Copper Mountain, Nickel Plate, and our Max copper-gold target are not random. We believe a 40 km structure along the southern margin of the Bromley Batholith controlled the emplacement of the smaller intrusions that carry the copper and gold. Younger volcanic rocks covering this zone have largely kept it untested, and this is the type of opportunity we like to focus on,& said Mark Kolebaba, President and CEO of Adamera.

Rationale for Staking

• A district-scale corridor: The Company interprets an east-west structural and metallogenic corridor, approximately 40 km in length, extending from the producing Copper Mountain mine through the Max Copper-Gold Target to the historic Nickel Plate (Hedley) mine. This corridor roughly tracks the southern margin of the Bromley Batholith and is interpreted as a deep-seated east-west cross-structure located within the Quesnel Trough. The corridor is considered a conduit for mineralizing magmas.

• A long-lived magmatic conduit:The Company&s interpretation suggests this 40 km east-west structural corridor acted as a deep crustal conduit over a 15-million-year metallogenic epoch. This long-lived weakness may have facilitated the earlier emplacement of the mineralizing intrusions at Copper Mountain and Nickel Plate, and ultimately controlled the emplacement of the Bromley Batholith along the trend. Economic copper-gold mineralization in this district is driven by smaller, highly fractionated intrusions tapping this structural corridor, making the covered southern margin of the Bromley Batholith a prospective target.

• Covering the missing link: The Bromley claim applications cover the interpreted southern margin of the Bromley Batholith, an area approximately 12 x 4 km in extent. While younger, post-mineralization cover conceals this zone, Adamera has identified distinct magnetic features within the corridor, providing early geophysical support for targets.

• Contiguous with an active target: These new applications extend directly westward from the Company&s South Hedley Property, where an ongoing induced polarization (IP) survey has defined a chargeability anomaly ranging from 3 to 4 km in width. This land expansion covers the interpreted structural corridor extending westward from this new zone.

Next Steps

This geological model is based on interpretation and needs to be tested through exploration work. The Bromley claim applications are currently subject to approval. Upon approval, anticipated initial work on the new claims would include prospecting, sampling, and potential airborne geophysics to define drill targets.

South Hedley Project

South Hedley is a copper-gold property near Princeton, British Columbia, within the Quesnel Trough. Work to date has advanced two targets: the Max Copper-Gold Target, a covered porphyry target defined by coincident copper-gold soil geochemistry, magnetics and IP; and Glix, a gold skarn target defined by soil geochemistry, electromagnetic and magnetic survey data. The IP survey at Max copper-gold target is currently underway. Drill permit applications for both targets were submitted in February 2026 and remain pending.

Martin St. Pierre, P. Geo., 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. The Copper Mountain and Nickel Plate mines are located on properties adjacent to or near the South Hedley Property. Information regarding those properties is drawn from public sources and has not been independently verified by Adamera. Mineralization on those properties is not necessarily indicative of mineralization on the South Hedley Property.
