What Minopex does

Minopex is a South Africa-headquartered specialist in plant operations and maintenance (O&M) services for the global mining sector, founded in 1996 as a wholly owned subsidiary of DRA Global. The company employs over 2,000 personnel across 14 countries and has operated approximately 50 mineral processing facilities while commissioning and ramping up more than 90 plants globally. Its customer base spans enterprise mining operators across multiple commodities — platinum group metals, gold, coal, iron ore, chrome, diamonds, and critical/battery minerals — with long-tenure anchor clients including Sibanye-Stillwater's Kroondal PGM plant (continuous operation since 1999) and Ma'aden's Ad Duwayhi gold operation in Saudi Arabia (since 2015). The company is headquartered in Johannesburg (Woodmead) with regional offices in Maputo, Mokhotlong (Lesotho), and Riyadh.

The company's core offering integrates plant operations, maintenance execution, asset management, metallurgical optimization, and continuous improvement under long-term managed-service contracts. It operates through dedicated sub-brands: Quality Laboratory Services (QLS) provides SANAS ISO 17025-accredited laboratory testing in South Africa, Saudi Arabia, and the EMEA region; EnSerSa delivers bespoke engineering services including fabrication, pipe management, and structural integrity; DRA Water handles integrated water operations; Longmech Mining provides mechanised underground caving services; and the SWAT team specializes in commissioning and ramp-up. The technology backbone is the NeuroMine Mining Insights Centre, launched in June 2023, which centralizes real-time monitoring, predictive analytics, and AI-driven optimization across multiple operations, supported by proprietary tools including the MinePulse chatbot, ProLET process-loop efficiency tracking, and APM asset performance management.

Minopex generates revenue through long-term O&M contracts with mining asset owners, supplemented by professional services revenue from laboratory testing and bespoke engineering. Pricing is not publicly disclosed; contracts are negotiated based on scope, plant complexity, and contract terms. The go-to-market model is enterprise field sales with direct engagement to mining executives and operations teams, supported by regional offices across Africa and the Middle East. Distribution is entirely direct, with no resellers or intermediaries, and marketing relies on industry conferences (Future Minerals Forum, MineSafe, COALSAFE, Africa Down Under), thought-leadership content, community engagement, and CSR initiatives to build brand reputation in the mining sector.
