Vancouver, British Columbia – May 13, 2026 – TheNewswire – Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) (“Adamera” or the “Company”) announces it has received approval from the B.C. Ministry of Mining and Critical Minerals to conduct an Induced Polarization (IP) survey at the Max copper-gold porphyry target on its 100%-owned South Hedley property. The survey is scheduled to commence in June.

The South Hedley property is located 18 kilometres (“km”) east of the Copper Mountain mine near Princeton, BC and 12 km southwest of the Nickel Plate mine near Hedley, BC.

The planned 44-line-kilometre IP survey will cover a 2 km magnetic anomaly surrounded by a 3 km horseshoe shaped copper-gold soil anomaly (see Figure 2). Peak values from these samples yielded up to 1.3 g/t gold and 1,450 ppm copper. The IP survey will map chargeability and resistivity at depth to define the distribution of sulphide mineralization and alteration. Data generated from this survey will be used to prioritize targets for drilling.

The Company originally submitted a Notice of Work application in February 2026 outlining both the IP survey and drilling program. The drilling component of the application remains under active review by the Ministry.

Map shows copper and gold soil anomalies in relation to inverted magnetic anomaly target at 160 metres depth slice.  Dash-lines represent proposed IP survey line locations. Orange circles represent gold values between 25 to 1600ppb. Copper shown in green ranges from 50 to 1450 ppm.

Mark Kolebaba, President and CEO of Adamera Minerals, stated: "We have identified two highly prospective targets at South Hedley: Glix and Max. This is a significant development for Adamera. Our initial program was primarily designed to identify gold skarn mineralization similar to the historic Nickel Plate mine, which the Glix prospect represents. However, the Max target introduces an entirely new dimension as a potential copper-gold porphyry. The large 3 km horseshoe-shaped copper soil anomaly at Max exhibits the classic signature of a porphyry system. It amazes me to think that we have identified these targets in southern British Columbia."

The BC Copper-Gold Trend: Geological and Investment Significance

The South Hedley property is situated within the Quesnel Terrane, a globally recognized and highly endowed geological belt often referred to as the BC copper-gold trough (see inset figure on Figure 1). This Triassic-Jurassic volcanic arc is renowned for hosting large-scale, long-life porphyry and skarn deposits driven by deep-seated magmatic systems. Geologically, this regional axis controls the mineralization at both the Nickel Plate gold Mine  and the Copper Mountain Mine.

The South Hedley property benefits from exceptional infrastructure, including year-round road access, nearby power and proximity to established mining communities. This logistical advantage significantly reduces exploration costs and lowers the capital expenditure required for development.

The Glix Prospect

In addition to the Max target the Company is advancing the Glix Prospect, a separate gold discovery located 15 km from the Max target. Recent exploration yielded soil samples with up to 4 g/t gold. The anomalous samples are associated with shallow electromagnetic (EM) conductors and a prominent magnetic low. Based on this data, the Glix target is considered to be comparable to the gold-bearing skarn environment seen at the historic Nickel Plate Mine.

Martin St. Pierre, P.Geo., a Qualified Person (QP) as defined by National Instrument 43-101, has reviewed and approved the technical data presented in this news release. Gold  data provided by Act Labs fire assay in Kamloops and by Adamera in-house lab using DetectOreTM method. Copper Values by Adamera using XRF.
