Leach Ore Placed in Stockpiles per Day

Leach ore placed in stockpiles per day measures the daily material rate delivered to leach operations, a distinct processing path from conventional milling.

leach ore placed in stockpiles per day measures the average tonnes of ore placed on leach stockpiles or pads for recovery through leaching.

Processing path

Freeport-McMoRan reported 148,700 metric tons per day of leach ore placed in stockpiles across its South America operations in 2025. The metric provides a physical scale measure for leach operations alongside ore grade and recovered copper production.

Investor caution

Ore placed is not immediate copper production. Leach recovery occurs over time, so inventory residence time, acid consumption, mineralogy, recovery curves, and prior-period stockpiles can separate placement from current-period metal output.

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.
