Yellow Pine Antimony Project.
RMX’s Yellow Pine Antimony Project is located within the Stibnite Mining District, which was a major source of antimony in the first half of the 20th Century. Recorded production from
the Yellow Pine and Hangar Flats deposits between 1932 and 1952 totaled 39,930 tonnes of Antimony.
Project Overview
The project lies within 2km of Perpetua Resources’ (Nasdaq/TSX: PPTA) Stibnite Gold-Antimony Project, which hosts a Proven and Probable Mineral Reserve of 4.8Moz gold and 148Mlbs antimony. Perpetua recently received final federal clearance to progress construction of its Stibnite operation, underscoring strong government and regulatory support for critical minerals development in the region.
Mineralisation in the Stibnite District is controlled by regional faults and splays, occurring within both the Idaho Batholith and surrounding sedimentary rocks. RMX’s Yellow Pine claims feature prospective host rocks, a major northeast-striking fault with mapped tectonic breccias, and numerous historical workings, likely targeting gold and/or antimony.
Exploration Plans
RMX’s immediate focus is on mapping and sampling historical workings, structural interpretation, and geophysical surveys to define drill-ready targets.
The project was acquired through direct claim staking by RMX’s U.S.-based technical team and funded internally, with no third-party vendors. Yellow Pine complements the Company’s Utah Antimony Project, positioning RMX to benefit from the U.S. government’s critical minerals strategy, including discussions of a potential US$5 billion federal support fund.
Following a heavily oversubscribed $1.5 million placement, RMX is well-funded to advance exploration across both U.S. projects while assessing further U.S. expansion opportunities and a potential U.S. stock market listing to support its growing Antimony and Critical Minerals portfolio.
