What are Treatment Charges?

Treatment charges (“TCs”) are an important component of revenue for a smelter. They represent the cost of converting a tonne of concentrate into zinc metal paid by miners. TCs are negotiated between miners, traders and smelters on the benchmark or spot market, or via fixed contracts. Benchmark represents the annual view of the global zinc concentrate market typically negotiated between major smelters and miners, whereas spot represents a current negotiation and is more indicative of current market conditions. As a result, TCs are affected by both current and annual views of supply and demand.

What is the concept of the smelter revenue model?

A smelter generates revenue from four main sources: free metal, treatment charges, by-products, and metal premiums.

Typically, smelters buy concentrate and pay for approximately 85% of the contained metal, or less, if the grade is low. A smelter recovers around 96% of the zinc, allowing it to generate free zinc revenue. Smelters also charge mines a fee (treatment charges or “TCs”) based on the tonnes of concentrate to be processed. To a lesser extent, a smelter also generates revenue from the sale of zinc metal by-products and from metal premiums on the zinc sold.

What is the proposed use of zinc?

Zinc is the fourth most used metal worldwide, behind iron, aluminum, and copper. Zinc metal serves many important purposes. Protecting steel against corrosion is the most important market for zinc, representing approximately 60% of zinc use globally. Zinc is also used in automotive components, batteries, fertilizers, and medical applications. Zinc metal is derived from the processing of zinc concentrates (ore that contains zinc) which are produced by zinc mines and then shipped to smelting facilities for further processing and refining. Smelters convert zinc concentrates into pure or refined zinc metal products destined for these various markets and end-uses.
