A technical study on Red Mountain Mining’s (ASX: RMX) Silver Dollar antimony project in Idaho has highlighted the district’s prolific status, with prospects immediately surrounding existing claims reporting historical assays of up to 85.7 grams per tonne silver and 17.5g/t gold.
The findings highlighted multiple bedrock and alluvial precious metal occurrences containing historical pits and adits associated with quartz veining and shear zones within the Idaho Batholith.
Historic quartz vein samples returned best results of 6.9g/t gold from the Blind Ledge target and 85.7g/t silver from Klondyke, while Iron Crown had visible mineralisation containing 17.5g/t gold and 14.7g/t silver.
Red Mountain’s field team plans to search for the presence of late dykes, veining, and shearing within the Silver Dollar area, as well as sample any quartz veining or alteration that may host mineralisation.
The company will then incorporate the results into the maiden exploration program it is launching this week.
Historical Exploration
The company commissioned the study after it ++acquired the project++ to identify high-priority targets and secure new claims at the historical Silver Dollar mine.
The project features multiple antimony, silver and gold mineral occurrences, including the historical mine based on a 10 metre shaft sunk into fractured granodiorite in 1944 to target a massive stibnite vein up to 1m thick.
Red Mountain believes this vein is related to a steeply north-dipping fault with host rocks displaying an analogous geological setting to Perpetua Resources’ nearby Stibnite project which hosts 4.8 million ounces gold and 148 million pounds antimony.
Previous production from the Silver Dollar mine estimated average ore grades of up to 14.6% antimony and 6.9g/t silver from a single sample.
In addition to the Silver Dollar, Yellow Pine (antimony) and Utah (antimony) projects, Red Mountain is actively pursuing opportunities to leverage the shortage of Western critical minerals supply and US government interest in strategic commodities.
The company recently ++debuted on the US mid-tier OTCQB market++ to increase its capital markets exposure, and help expand its portfolio of high-quality critical and strategic metals projects in Tier 1 US mining jurisdictions.
