Producer
Minsur
Peru's dominant tin producer and the world's second-largest refined tin producer (36,300 MT in 2024, ~10% global share). Operates San Rafael — the world's deepest tin mine at ~1,000 m underground in Puno region, Peru — and the FUNSUR smelter (Pisco, Ica). Part of the Breca Group (Brescia family conglomerate). San Rafael has been in production since 1977. 36% of US refined tin imports in 2024 originated from Minsur/Peru.

Did you know2024
Minsur's refined tin from San Rafael mine simultaneously serves two supply chains that define very different eras of industrial civilization: (1) food preservation — tin coated on steel creates the hermetic barrier in food cans that has preserved food without refrigeration for 200 years, from Napoleon's military rations to modern pet food; and (2) electronics assembly — tin-based solder (tin-lead historically; lead-free tin-silver-copper now mandated by EU RoHS) bonds every integrated circuit to every circuit board in every electronic device manufactured since the transistor era. The tin in a sardine can and the tin in the solder joints of the semiconductor IC processing that sardine can supply chain order are both potentially sourced from the same Puno, Peru high-altitude mine. The same Andean ore body that humans excavated 1,000 meters underground provides the metal that preserves food AND assembles electronics — two of the most consequential material technologies of the last two centuries sharing one Peruvian origin.
Minsur S.A. ↗Origin2023
Minsur S.A. is owned by the Breca Group (formerly Brescia Group) — the Brescia family's Peruvian industrial and financial conglomerate. The Brescia family are Italian-origin Peruvian industrialists who built one of Peru's largest private groups spanning banking (BBVA Peru stake), healthcare, supermarkets, and mining. San Rafael mine in Puno was acquired by Minsur in 1977 — shortly after Peru's military government of Juan Velasco Alvarado had nationalized and then partially re-privatized mining operations. The San Rafael mine, operating since 1977 at up to 1,000 meters underground in the Peruvian Andes, is the world's deepest operating tin mine. The mine's depth (ore bodies at extreme depth in the altiplano, high-altitude Andean plateau) creates unusual mining conditions — miners work at 4,000+ meters altitude with extreme temperature gradients between surface and underground. Minsur's FUNSUR smelter on Peru's Pacific coast was built to convert San Rafael concentrate to refined tin for export.
