Adamera Minerals Advances Four Gold Projects in Washington and British Columbia

Adamera Minerals Corp. has provided a comprehensive update on its portfolio of four gold projects spanning Washington State and British Columbia, representing more than a decade of grassroots exploration work. The company's strategic focus on both grassroots and brownfield discoveries in established mining jurisdictions positions it for potential significant discoveries, particularly given current funding limitations that have restricted follow-up drilling on compelling targets.

The South Hedley Gold property in British Columbia covers 18,714 hectares south of the historic Hedley mining district, which has produced over 2.5 million ounces of gold from skarn-hosted deposits. 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. 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 defined a coherent zone with soil samples consistently anomalous in gold, arsenic and zinc, including one sample of 419 ppb gold.

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 near an area mined by Hecla Mining that produced more than 2.8 million ounces of gold and 15 million ounces of silver. 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 2m intervals. Combined ground magnetic data and surface soil geochemistry demonstrate potential for numerous untested veins, with the company planning deeper drilling later in 2025.

The Empire Creek Property, located on the same structural corridor as the historic K2 and Granny Mines approximately 6 km to the north, represents another drill-ready opportunity. Historic drilling intercepted 10.5 g/t gold and 183.3 g/t silver over 15.24m starting at a depth of 54m. Recent exploration by Kinross Gold Corp. at the K2 site has resulted in discovery zones of high-grade epithermal gold mineralization, suggesting similar potential at Empire Creek.

Perhaps most significantly, the Buckhorn 2.0 Property encompasses a large land package surrounding Kinross Gold Corp's past-producing Buckhorn Mine, with existing infrastructure including haul roads, power transmission lines and a nearby mill. Adamera has modeled more than 30 exploration targets based on geological characteristics of the Buckhorn Mine, which developed a structurally controlled skarn/carbonate replacement gold system. To date, the company has only tested 4 of 40 targets, with shallow zones of gold mineralization already intersected.

The importance of these developments lies in their potential to unlock new gold resources in established mining districts with proven production histories. As Mark Kolebaba, President and CEO of Adamera, stated, "Many compelling targets are drill-ready such that Adamera can offer a balanced mix of both grassroots and brownfield discoveries in established mining jurisdictions." The company's systematic approach, using advanced exploration techniques including the detectORE method for rapid gold analysis, has identified multiple high-priority targets across all four properties.

For investors and the mining industry, Adamera's progress represents potential value creation through methodical exploration in jurisdictions with existing infrastructure and mining-friendly regulations. The projects' advancement comes at a time when gold exploration is increasingly focused on established districts rather than greenfield discoveries, potentially offering lower-risk development opportunities. The company's work, documented in various technical reports including those available at government geological surveys and state mineral resource documents, demonstrates the ongoing potential for significant discoveries in mature mining regions.
