Central Idaho Antimony
Potential for a large, bulk-mineable antimony-gold system with a clear pathway to development
Comprising 52 unpatented lode mining claims, the project is situated in Elmore County, Idaho, a Tier 1 mining jurisdiction with a long track record of successful resource development.
The CIA Project is situated within the historically productive Swanholm Mining District (also known as the Middle Boise), which has a documented history of high-grade antimony and precious metals production.
Geological Setting
The regional geological setting of the Swanholm District is vital for its exploration prospects. The entire district sits within a dropped fault block called the Swanholm graben, bounded by two major regional faults that strike northwest: the Deer Park fault to the east and the Swanholm Creek fault to the west. This structural arrangement is highly important, as it indicates the potential preservation of a complete epithermal mineral system.
The two primary structural orientations within the camp are:
- A northwest-trending corridor (N15W or 345°), defined by prominent structures including the Deer Park and Swanholm Creek Faults. This corridor is at least 6 km2 in area and 2 km wide.
- A northeast-trending belt (N50E−N60E or 050°−060°), which includes the well-documented Black Warrior Porphyry Belt Structure and the extensive Middle Fork Lineament tectonic zone.
Geological evidence at CIA supports exploring both high-grade, structurally controlled veins and a larger bulk-tonnage stockwork system, offering flexibility for future development.
Exploration Potential
Trigg has developed a systematic, low-cost, and high-impact exploration program aimed at quickly progressing towards the high-priority targets identified during the initial due diligence and reconnaissance stages. The program concentrates on defining the geometry, grade, and extent of the known mineralised zones to ready them for drill testing. This will commence with:
- Systematic trenching and channel sampling
- Re-opening and Sampling of Historical Adits
- Prospecting and mapping
- Claim expansion
- Advanced geospatial analysis.
