Adamera Minerals Advances Four Gold Projects with Drill-Ready Targets in Washington and British Columbia

Adamera Minerals Corp. has provided a comprehensive update on its portfolio of four gold projects across Washington State and British Columbia, highlighting significant exploration progress and multiple drill-ready targets. The company's 12-year grassroots exploration program has yielded promising results across all properties, with several high-priority targets now advancing toward drilling phases.

The South Hedley Gold property in British Columbia covers 18,714 hectares south of the historic Hedley mining district, an area with substantial production history. Adamera's work has identified multiple structural corridors containing skarn-related and quartz-carbonate vein occurrences similar to those at the Mascot mine and Barrick Gold Corp's historic Nickel Plate mines, which reported production exceeding 2.5 million ounces of gold according to historical data from provincial geological records. The company has advanced two key prospects: the Max Prospect, defined by a zone with highly anomalous gold, copper and arsenic in soil and rock samples, and the Glix Prospect, where follow-up sampling has revealed a coherent zone with soil and rock samples consistently anomalous in gold, arsenic and zinc.

In Washington State, the Flag Hill and Flag Hill South Gold-Silver Properties are situated in the Republic Gold District, part of a larger epithermal gold-silver vein system. Historical production in this camp is estimated at more than 2.8 million ounces of gold and over 15 million ounces of silver, as documented in Washington Department of Natural Resources reports. Drilling by Adamera in late 2024 intersected epithermal veins at shallow depths with zones containing 3.0 g/t gold and 70 g/t silver over 2-meter intervals. The company plans deeper drilling later in 2025 to test veins at greater depth and investigate a pronounced magnetic anomaly that may represent an intrusive center driving mineralization.

The Empire Creek Property, located on the same structural corridor as the historic K2 and Granny Mines approximately 6 kilometers to the north, represents another drill-ready opportunity. Historic drilling at Empire Creek intercepted 10.5 g/t gold and 183.3 g/t silver over 15.24 meters starting at 54 meters depth. The property's proximity to the Republic graben margin and recent discoveries by Kinross Gold Corp at the K2 site underscore its exploration potential. As reported by local media coverage, the K2 mine was initially operated by Echo Bay before Kinross took over operations.

The Buckhorn 2.0 Property encompasses a large land package surrounding Kinross Gold Corp's past-producing Buckhorn Mine, which became operational as documented by industry publications. Adamera has modeled more than 30 exploration targets based on geological characteristics of the Buckhorn Mine's structurally controlled skarn/carbonate replacement gold system. The property benefits from existing infrastructure including haul roads, power transmission lines and a nearby mill. To date, the company has tested only 4 of 40 identified targets, with shallow zones of gold mineralization already intersected but requiring follow-up drilling.

President and CEO Mark Kolebaba emphasized that while drilling follow-up has been limited due to funding constraints over the past decade, the company now offers a balanced mix of grassroots and brownfield discoveries in established mining jurisdictions. The advancement of these projects comes at a time when gold exploration in proven districts represents a strategic approach to mineral discovery, leveraging historical data and modern exploration techniques to identify new mineralization opportunities near existing infrastructure and known deposits.
