Trigg Minerals has acquired a 100% stake in the Central Idaho Antimony Project, a district-scale high-grade antimony-gold asset in a Tier-1 US jurisdiction, supported by a $5 million strategic placement from Tribeca Investment Partners.
- Acquisition of 52 mining claims in Central Idaho’s Swanholm District
- High-grade surface samples up to 17.6% antimony and significant gold assays
- Strategic $5 million placement from Tribeca Investment Partners
- Project shares geological similarities with Perpetua’s Stibnite Gold Project
- Minimal environmental legacy and strong infrastructure reduce permitting risk
Strategic Acquisition in a Tier-1 Mining Jurisdiction
Trigg Minerals Limited (ASX, TMG) has announced a significant expansion of its critical minerals portfolio with the acquisition of a 100% interest in the Central Idaho Antimony (CIA) Project. Located in Elmore County, Idaho, this district-scale landholding covers 52 unpatented lode mining claims within the historically productive Swanholm Mining District. Idaho’s status as a Tier-1 mining jurisdiction adds a layer of geopolitical and operational stability to the project, a rare find for a deposit of this scale in the United States.
High-Grade Mineralisation and District-Scale Potential
The CIA Project boasts exceptionally high-grade surface rock chip results, including assays up to 17.6% antimony (Sb) and notable gold values reaching 3.1 grams per tonne (g/t). Newly identified prospects such as the A47 Showing and the Svensson Prospect reveal robust quartz-stibnite vein systems with both precious and critical metals. Historical workings and recent reconnaissance sampling confirm a polymetallic system with potential for both high-grade direct shipping ore and a larger bulk-tonnage stockwork vein model.
Complementing an Expanding US Critical Minerals Portfolio
This acquisition complements Trigg’s existing US assets, including the Antimony Canyon Project in Utah and the Tennessee Mountain Tungsten Project in Nevada. The company’s Managing Director, Andre Booyzen, emphasised that the CIA Project strengthens Trigg’s position as a leading critical minerals explorer in America. The project’s geological setting shares key similarities with Perpetua Resources’ Stibnite Gold Project, which has attracted substantial US Department of Defence funding, hinting at potential federal support for the CIA Project’s development.
Strategic Investment and Exploration Plans
Backing this acquisition is a $5 million strategic placement by Tribeca Investment Partners, an internationally renowned investment firm. This injection not only bolsters Trigg’s institutional register but also brings valuable industry expertise. Trigg plans a systematic exploration program focusing initially on trenching, channel sampling, re-opening historical adits, and extensive geological mapping. The company also intends to expand its land position by staking additional claims to cover highly prospective structural intersections.
Environmental and Permitting Advantages
One of the project’s notable advantages is its minimal environmental legacy. Historical ore processing occurred off-site, leaving the project area free from legacy tailings or contaminant waste rock dumps. This clean baseline is expected to streamline permitting processes, a critical factor given the strategic importance of antimony and gold in supply chains. The existing infrastructure, including maintained gravel roads, further reduces logistical challenges and exploration costs.
Bottom Line?
Trigg Minerals’ acquisition and strategic partnership position it at the forefront of US critical minerals exploration, but the path from promising assays to production will require careful navigation of exploration and regulatory milestones.
Questions in the middle?
- How will Trigg’s exploration results evolve as systematic drilling begins at the CIA Project?
- What role might federal funding or incentives play in accelerating project development?
- How will the $5 million placement from Tribeca influence Trigg’s capital strategy and shareholder composition?
