Trigg Minerals expands Antimony Canyon, eyes near-term mining

• Trigg Minerals has secured new ground to the north and south of its Antimony Canyon project
• Move ensures control of interpreted extensions of the mineralised structures and increases potential scale
• Company plans pilot-scale mining to aid with metallurgical testwork, feasibility input and processing validation.

Special Report: With rising global tensions and the US pushing to develop domestic antimony production, Trigg Minerals has moved to improve its strategic position by expanding its Antimony Canyon project in Utah.

It has also launched initiatives aimed at achieving near-term pilot-scale antimony mining.

Trigg Minerals (ASX:TMG) has confirmed widespread antimony mineralisation in areas previously untested by historical resource work at the Antimony Canyon project.

It has also confirmed that antimony mineralisation occurs throughout the vertical profile of the Flagstaff Formation, substantially increasing the potential scale of mineralisation throughout the project tenure.

Antimony mineralisation has been confirmed in the Dry Wash Canyon about 10km to the north, which could be linked to Antimony Canyon by significant north-south trending structures that are indicated by the new geological interpretation to control mineralisation.

While much of the intervening area between these two zones is covered by mass flow deposits that have historically obscured the underlying prospective geology, the company has moved to strategically expand its landholding by staking new claims that extend north from Antimony Canyon to Dry Wash Canyon and beyond.

The company has also staked new claims to the south of Antimony Canyon to further consolidate its position in the region, ensuring that it controls the interpreted extensions of the mineralised structures and the potential for a materially larger resource under modern exploration.

“The confirmation of antimony mineralisation outside our known resource, particularly at Dry Wash Canyon, and the emerging understanding of these controlling north-south structures, is a game-changer for the Antimony Canyon project,” managing director Andre Booyzen said. 

“This strategic expansion of our landholding underscores our commitment to establishing a robust presence in the critical minerals sector and positions Trigg Minerals to contribute significantly to America’s future antimony production landscape.”

Pilot-scale mining

TMG has also developed a plan to start pilot-scale mining on selected sections of the project to aid with metallurgical testwork, feasibility input and processing validation.

Pilot-scale mining will take place from surface using mechanical methods with mined material crushed on site by means of mobile crushing before the antimony is upgraded using gravity separation.

Antimony not recovered using gravity separation will be stockpiled for future recovery via flotation.

Antimony Canyon is the largest and highest-grade antimony project in the US with a non-JORC resource estimate of 12.7Mt at 0.79% antimony for 100,300t of contained antimony.

It incorporates several historical producing mines including Emma, Mammoth and Nevada.

TMG recently appointed highly experienced antimony downstream expert Wiehann Kleynhans as its vice president, US downstream operations, to bolster its antimony capabilities.

Kleynhans will develop a strategy for North America, which will include options for downstream processing, form partnerships with key industry and government players in North America as well as identify and negotiate possible offtake agreements with international antimony traders.

He will also assist the company with obtaining US government funding for exploration and development while assisting with due diligence on future antimony projects.
