Resolution Minerals (RML) released an update as it advances its tungsten exploration and development activities at its Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho.

This advancement follows positive evaluation of historical data from the site, discussions with a prior operator of the Golden Gate Tungsten Mine and results from recent drilling.

To accelerate these efforts, Resolution Minerals has retained David Hembree, CPG, a former mine geologist at Resolution’s past-producing Golden Gate Tungsten Mine who is extremely familiar with the tungsten at Golden Gate and a tungsten expert, to accelerate exploration and development activities. This will include analysis of historical tungsten exploration data, ground-based fieldwork, a drill program to commence in June 2026, and metallurgical test work on existing tungsten stockpiles.

David Hembree, who has 45 years’ experience in geology in the western USA, was the last mine geologist to have worked at Golden Gate Tungsten Mine in 1980 and 1981 while employed with TRV Minerals. In addition to being a highly accomplished explorationist, his experience as mine geologist with several operating mines in the United States, including Mount Hamilton, French Gulch and Mineral Ridge, will be invaluable to Resolution as it moves to rapidly develop Horse Heaven.

Hembree will support RML’s tungsten exploration and development activities at both the Golden Gate Target and other emerging targets within Resolution’s 100 percent owned Horse Heaven Gold-Antimony-Tungsten-Silver Project. His knowledge of past exploration and production of tungsten at Horse Heaven is expected to be invaluable in identifying additional tungsten resources.

“We are fortunate to have connected with David Hembree, who has a strong knowledge of historic tungsten exploration and production at Horse Heaven, and he will be invaluable as Resolution begins the process of targeting additional tungsten resources at Horse Heaven,” said Craig Lindsay CEO of U.S. Operations.

“Based on our work to date, we are confident additional ore remains at the historic Golden Gate Tungsten Mine, as was as at other emerging targets at Horse Heaven. Dave, with his understanding of the historic workings and mineralization, has already provided excellent insight into where we should be focusing future tungsten-oriented drilling activities,” added Lindsay.

“I am very excited to be back working at the Horse Heaven Project and am eager to put my knowledge on the project’s tungsten potential to work. There is a clear path to resource growth at the historic mine, and I am aware of other targets that have yet to be explored. For instance, to the south of the historic mine there is a significant tungsten anomaly identified through a historic soil sampling program that has never been drilled. The broader project, beyond Golden Gate, is a target-rich environment,” said Dave Hembree.

The Golden Gate Tungsten Mine produced tungsten ore intermittently from approximately 1952 to 1980. Ore from Golden Gate was processed at the nearby Stibnite Mill in the 1950s, and then at the Johnson Creek Mill, a custom milling facility which processed tungsten ore from Golden Gate intermittently until approximately 1980.

In parallel, Resolution is acquiring the historic Johnson Creek Mill. Ongoing due diligence on the Johnson Creek acquisition is nearing completion.

Near term work on tungsten at the Horse Heaven Project includes data compilation and assessment, metallurgical testing on historic stockpiles of tungsten mined at the Golden Gate Tungsten Mine, ground based sampling, geophysics and a drill program to be initiated in June 2026.

Resolution Minerals a mineral exploration company, engages in the acquisition, exploration, and development of mineral properties in Australia and the United States. The company primarily explores for gold, copper, nickel, cobalt, iron ore, nickel, silver, manganese, and uranium deposits, as well as silica sands and battery metals. The company is headquartered in Adelaide, Australia.
