Resolution Minerals is pleased to provide an update as it advances its tungsten exploration and development activities at its Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, USA. 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 Mr. David R. 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.
HIGHLIGHTS
- Resolution Minerals (ASX: RML; OTCQB: RLMLF) has engaged the services of Mr. David R. Hembree, CPG, a seasoned geologist with direct experience at Resolution’s historic Golden Gate Tungsten Mine, to fast-track tungsten exploration and development activities.
- Mr. 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 Corp. 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.
- Mr. Hembree will support RML’s tungsten exploration and development activities at both the Golden Gate Target and other emerging targets within Resolution’s 100%- 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.
- 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, which comprises a past-producing processing facility and stockpiles of an estimated 2,000 tonnes of tungsten ore (see ASX announcement 31 October 2025), and is located immediately adjacent to Horse Heaven.
- Ongoing due diligence on the Johnson Creek acquisition is nearing completion.
- Resolution believes that additional potential exists to expand tungsten mineralisation at and around the historic Golden Gate Tungsten Mine, along strike to the north and south parallel to the north-south oriented Golden Gate Fault and, potentially, at other targets at the Horse Heaven Project. A combination of ground-based exploration, geophysics, historical records and other tools will be used to develop an exploration plan to test these theories.
- Resolution 100%-owned Horse Heaven Project is located in the Boise National Forest, covering ~ 59km2 of land immediately adjacent to the fully-permitted A$5 billion Stibnite Gold Project operated by Perpetua Resources Corp (NYSE:PPTA).
- Tungsten (APT) prices are currently at a record high $900/mtu and expected to rise significantly in 2026 on the back of increased global conflict, and rising demand from clean energy and high-tech applications including AI chips and lithium-ion batteries.
We are fortunate to have connected with Mr. Hembree, who has a strong knowledge of historic tungsten exploration and production at Horse Heaven, and will be invaluable as Resolution begins the process of targeting additional tungsten resources at Horse Heaven. Based on our work to date, we are confident additional ore remains at the historic Golden Gate Tungsten Mine, as well as at other emerging targets at Horse Heaven. Dave, with his understanding of the historic workings and mineralisation, has already provided excellent insight into where we should be focusing future tungsten-oriented drilling activities.
