Trigg Minerals (ASX:TMG) said recent exploration programs carried out at its US Antimony Canyon Project have established a new mineralization model that reinterprets the project as a potential district-scale, high-sulfidation epithermal system, according to a Wednesday Australian bourse filing.

The company said that multiple stacked, sub-horizontal mineralised layers within the favourable tuff unit have been discovered, which enhances the project's tonnage potential and offers an advantageous geometry for future development.

The company added that systematic channel sampling within the patented claims has previously yielded high-grade antimony results, including 1.5 meters at over 33% antimony, which indicates the presence of a fertile epithermal system.

Major targets are located within the company's patented claims, providing a more direct approvals pathway that can shorten development timelines and enhance project value, the filing added.

The company's shares fell 5% in recent Wednesday trade, earlier hitting an all-time high.
