Minsur Q3 production rises as prices boost profits

Peruvian tin producer Minsur reported a 3.8% year-on-year increase in refined tin production in Q3 2026, supported by higher mine output and increased throughput at its Pisco smelter.

The world's second-largest refined tin producer reported quarterly output of 9,028 tonnes, up 29% from Q2 2026 as production recovered following scheduled smelter maintenance earlier in the year.

At the San Rafael underground mine, tin-in-concentrate production increased 1.7% year-on-year to 7,090 tonnes, supported by a 5.2% increase in feed grades to 2.84% Sn and higher ore throughput.

Production from the B2 tailings dam fell 1.9% to 1,967 tonnes due to lower processing volumes and recovery rates, partially offset by higher feed grades. Total tin-in-concentrate production from the San Rafael mining unit increased 0.9% to 9,057 tonnes.

Refined tin output at Pisco increased 3.8% year-on-year as the smelter processed additional concentrate inventories.
