Current TC and RC annual benchmarks stand at TC $52 per dry tonne and RC 5.2 cents per lb (TC/RC 52/5.2) with no PP, which on a 30% Cu grade concentrate is equivalent to a charge of 13.35 US cents per lb of payable copper.

The reported TC/RC of 10/1.0, at which spot lots are trading today, reflect the extreme tightness in the current market for copper concentrates. On a 30% Cu grade concentrate this is equivalent to a charge of only 2.57 US cents per lb of payable copper.
