Horse Heaven now has two projects under the federal permitting framework
Resolution Minerals has secured FAST-41 Transparency Coverage for the Golden Gate Project in Idaho, giving the company a second project in the federal permitting system after Antimony Ridge.
The designation was announced on 17 July 2026. It supports Resolution’s plan to build a US antimony, tungsten and gold platform at its flagship Horse Heaven Project.
FAST-41 aims to improve the efficiency and transparency of permitting for strategically important infrastructure projects in the United States. As a result, Golden Gate may help accelerate permitting across the wider Horse Heaven Project.
Resolution linked Golden Gate’s inclusion to President Donald Trump’s Executive Order to increase domestic mineral production and reduce reliance on overseas critical minerals.
Golden Gate is the second Resolution project to receive FAST-41 status in 2026. Earlier in the year, Antimony Ridge received the same designation.
Both assets are Resolution’s main development targets at Horse Heaven. It is not aware of another critical metals company with two FAST-41 projects.
Johnson Creek Tungsten Mill
Horse Heaven includes more than the two deposits. The project also holds the recently acquired Johnson Creek Tungsten Mill, historical tungsten stockpiles and a fully funded Phase 2 drilling programme of up to 45 holes for resource definition.
Meanwhile, Horse Heaven sits next to Perpetua Resources’ Stibnite Gold Project in Idaho. That location places Resolution in a region the company views as increasingly important for US critical minerals development.
Golden Gate also includes a historical tungsten mine that operated intermittently between the 1950s and 1980. Reported production grades ranged from 1.5% to 2.0% tungsten.
Resolution said Golden Gate and Antimony Ridge support an integrated development pathway covering exploration, metallurgy and potential downstream processing.
Craig Lindsay, Resolution’s CEO – US Operations, called the FAST-41 outcome an important step. “We now have two separate development targets within the Horse Heaven Project under the FAST-41 programme,” he said.
Lindsay added that he was not aware of another critical metals company with two FAST-41 projects. He said that could show Horse Heaven’s importance to US efforts to build domestic antimony and tungsten supply.
