Trigg appoints antimony doyen for smelting strategy

Trigg Minerals (ASX:TMG) has appointed Wiehann Kleynhans as Vice President, US Downstream Operations to lead the company’s smelting and processing strategy in North America. 

Kleynhans is an experienced geologist, resource and commodity analyst, and dealmaker with experience in the global antimony sector. From 2021 to 2024, he was Head of Business Development at Strategic & Precious Metals Processing (SPMP) in Sohar, Oman, where he played a role in driving expansion and growth of international sourcing and supply chains for raw antimony as a member of the Executive Management Team. 

He oversaw the establishment of a global Business Development team, actively engaged in commercial negotiations and was involved in numerous offtake agreements.  

Kleynhans also developed and executed a global feedstock sourcing and trading strategy based on analysis and understanding of the international antimony market and fostered trusted business relationships with current and new suppliers to position SPMP as a global player in the antimony market. 

Previously, Kleynhans held Business Development Manager, Performance Improvement and Operational Readiness roles at MMG Limited and was Associate Director – Corporate Finance at Ernst and Young (EY) in South Africa. 

In his role at Trigg, he will develop a strategy for North America, which will include options for downstream processing (smelter); form partnerships with key industry and government players in North America; identify and negotiate possible offtake agreements with international antimony traders; assist Trigg with obtaining US government funding for exploration and development and assist with due diligence on future antimony projects. 

Kleynhans’ appointment follows Trigg’s recent acquisition of the Antimony Canyon Project in Utah, US. 

It also comes after Trigg in February 2025 joined the International Antimony Association (i2a), just a day after expanding its New South Wales antimony portfolio by acquiring the historic Bukkulla Mine, as reported by this news service.

The i2a is a Brussels-based organisation representing the producers, importers and users of multiple Antimony substances. Its aim is the sustainable and responsible production, use and recycling of antimony.

The organisation is a member of Eurometaux, the North American Metals Council, the International Council on Mining and Metals, and the Critical Raw Materials Alliance. 

As the global representative body for the antimony industry, i2a works to ensure the responsible production, use, and trade of antimony, while supporting regulatory and scientific initiatives. 

Membership provides Trigg with access to key industry stakeholders, regulatory developments, and global market insights, strengthening the company’s position as Trigg advances its portfolio of high-grade antimony projects.
