What SIGMA S.A. CHILE does

SIGMA S.A. Chile is a privately held industrial services company founded in 2006 and headquartered in Ñuñoa, Santiago, specializing in integrated services for the Chilean mining sector. The company delivers three core service lines — Puesta en Marcha (PEM/commissioning), Mantenimiento (maintenance), and Construcción (construction) — through project-based contracts executed by dedicated on-site teams at client mine sites. Its customer base is concentrated in large-scale Chilean copper mining, including five Codelco divisions (Chuquicamata, El Teniente, Salvador, Radomiro Tomic, and Andina), BHP operations (Escondida and Spence), and Sierra Gorda. The company employs 2,100+ workers across 45 active mining projects and maintains regional operations support in Calama alongside an R&D engineering office in Las Condes.

Revenue is generated through negotiated professional services contracts with no public pricing disclosure, with services priced and scoped per project. SIGMA's go-to-market is enterprise field sales via direct contractual relationships with major mining operators, where high safety standards (ISO 45001 / ACHS 45001 Excellence Level certification, 663,320 accident-free person-hours on the Codelco GEL contract) and operational track record serve as primary competitive levers. Beyond core services, SIGMA operates an active I+D+i (Research, Development, and Innovation) division with four CORFO-certified R&D projects: AI-based extended production models for industrial processes, an intelligent fatigue-detection helmet using biosignal monitoring, an AI-powered lithium battery energy management system, and the proprietary RETEXO Sensor with machine learning models for ICU sedation prediction. These R&D efforts span adjacent verticals (healthcare, renewable energy) but remain in development rather than commercial stages. Leadership includes Eduardo Correa (Director Ejecutivo), Roberto Valdés Peñailillo (Gerente General), and Verónica Pérez (Subgerente General), with no disclosed external institutional ownership.
