Wiehann Kleynhans to Spearhead Vertical Integration of Antimony Business in North America
Trigg Minerals has appointed antimony market veteran Wiehann Kleynhans as Vice President of U.S. Downstream Operations, a move that marks a major step forward in the company's strategy to become a vertically integrated antimony supplier in North America.
The appointment follows Trigg’s recent acquisition of the Antimony Canyon Project (ACP) in Utah and highlights the company’s transformation from a sulphate of potash explorer to a critical minerals developer with an international footprint.
Expertise to Match Strategic Ambition
Trigg Minerals Managing Director Andre Booyzen said Kleynhans' appointment validates the company's long-term antimony vision.
“Wiehann is an antimony specialist with years of experience negotiating offtake deals and navigating the complex global supply chain,” Booyzen said. “His appointment is a testament to the quality of our antimony assets and the team we are building.”
Track Record in Global Antimony Markets
From 2021 to 2024, Kleynhans led business development at Strategic and Precious Metals Processing (SPMP) in Oman — one of the few operational antimony smelters outside China. He expanded SPMP’s global sourcing network and negotiated multiple commercial offtake agreements. Prior roles include corporate finance and operational positions at MMG and Ernst & Young in South Africa.
Downstream Development and U.S. Supply Chain Push
At Trigg, Kleynhans will lead downstream planning, which may include:
- Building a domestic smelter
- Establishing industry and government partnerships
- Securing offtake agreements
- Accessing U.S. government funding for exploration and infrastructure
His appointment comes amid intensifying geopolitical pressure to diversify antimony supply chains away from China, which currently dominates global production.
A Critical Minerals Pivot
Trigg now holds two significant antimony projects:
- The Antimony Canyon Project in Utah
- The Wild Cattle Creek Project in New South Wales, Australia
Both assets are central to Trigg’s plan to supply strategic minerals to defense and energy sectors in the U.S. and allied markets.
“Our focus is on taking the Antimony Canyon and Wild Cattle Creek projects into development,” Booyzen said. “Wiehann will help us execute a strategy that delivers maximum value to our shareholders.”
