“I’ve worked with the Tamarack team at mines in Peru, Argentina and the US. Lee and his team have consistently produced significant AISC savings, even in technically demanding procurement categories. The key differentiator is how they work with the mining operations teams to find value, without compromising supplier quality and safety performance.”
