copper by-product credits per pound are secondary-metal revenues credited against copper costs under a by-product accounting presentation.

Cost bridge

Freeport-McMoRan's U.S. copper mines reported $0.59 per pound of by-product credits in 2025. Under the by-product method, those credits reduce the unit cost attributed to copper.

Investor caution

A larger credit can lower reported copper unit net cash cost even when mine-site spending is unchanged. The measure therefore depends on secondary-metal volumes and prices and should not be compared with a co-product presentation without reconciling the allocation method.

Part of the Mining Operating Economics

Connect mine throughput, ore quality and recovery, copper production and sales, realized pricing, per-pound operating costs, and sustaining-cost concepts to understand mining economics without flattening issuer-specific definitions.

How the model fits together
  • Throughput, grade, recovery, and output: Ore milled and leach ore placed show processing scale, while ore grade and metallurgical recovery explain how much contained metal becomes recoverable output. Copper production volume is the resulting reported output measure, but leach timing and mine sequencing prevent this from being a period-perfect accounting identity.
  • Production, sales, and unit realization: Production shows recoverable output, sales show the pounds monetized in the period, average realized price shows consolidated pricing, and revenue per pound plus gross profit per pound show an issuer-specific unit revenue and margin view. Inventory timing and operating scope can separate these measures.
  • Cash cost, accounting cost, and sustaining burden: Site production and delivery cost, by-product credits, and treatment charges bridge to issuer-defined unit net cash cost; DD&A and other noncash costs bridge toward total unit cost. Total cash cost, sustaining capital, AISC, and strip ratio add broader mining cost context, but gold-oriented and copper-oriented measures are not interchangeable standardized peer metrics.
