OSINERGMIN mining-safety sanctions in Peru, 2020 to date

Between Jan 10, 2020 and Aug 14, 2026, OSINERGMIN's mining supervision division issued 622 sanction resolutions against 115 large and medium mining companies in Peru, with fines totaling S/ 136,353,060 (about US$ 40.7 million). OSINERGMIN's own published sanctions list stops in December 2019; this record was obtained through a public-information (SAIP) request answered on Aug 28, 2026 and is indexed here in full.

Every resolution below names the company, the rule breached, the fine, and the payment state OSINERGMIN reports. Click a company for its resolution-by-resolution record. Mining Incidents is an independent index; the records are OSINERGMIN's own, kept verbatim in Spanish.

This is one layer of Peru's mining record. The regulator's own 2001-2019 list, OEFA environmental fines and MINEM's fatal-accident list are on the country page.

OSINERGMIN delivered this dataset on Aug 28, 2026 in answer to public-information request (SAIP) 202600187744, filed Aug 19, 2026 (response report 236-2026-OS-GSM). The delivery is formally partial: the agency states it does not hold, in the requested form, each company's tax ID (RUC), the mining unit, the supervision specialty, or the appeal status before TASTEM.

Companies by total fines

Company	Fines (S/) ⓘ S/ is the Peruvian sol, Peru's currency. The gray dollar figures are approximate conversions at S/ 3.35 per US$1 (August 2026).	Resolutions ⓘ A resolution (resolución) is OSINERGMIN's formal written decision closing one sanction case: an order from the regulator, not a court judgment. A single resolution can fine several infractions at once, and it can be appealed to TASTEM, the agency's own appeals tribunal.	Most recent

A resolution that sanctions a titleholder and its contractor jointly is attributed to each company named, so company totals can sum above the overall total.

The 622 resolutions break into 847 infraction line items. Amounts are the fine attached to each infraction as published, in Peruvian soles (S/); OSINERGMIN also states each fine in UIT, Peru's yearly-revalued tax reference unit.
