Revenue model

1. Copper Concentrate Sales: The mine exports copper concentrate to Chinese smelters via a dedicated haulage road. Copper production ramped up 9% year-over-year to 229,000 tonnes in Q1 2026, driven by continued expansion of underground mine. The mine is one of the world's largest copper projects.
2. Gold Production: Gold is co-produced as a byproduct of copper mining operations. The Oyu Tolgoi project is one of the world's largest copper-gold deposits.

Core offering

Oyu Tolgoi operates a large-scale copper and gold mining operation in Mongolia's South Gobi Desert, combining open-pit mining and underground block caving methods. Mined ore is processed through an on-site concentrator to produce copper concentrate and gold, which are exported primarily to Chinese smelters via a dedicated road haulage corridor.

Product overview

Oyu Tolgoi is a large-scale copper and gold mining operation in Mongolia's South Gobi Desert, operated by Rio Tinto. The operation consists of integrated mining, processing, and logistics components: Open Pit Mining accessing the Southern Oyu deposit, Underground Mining using block caving methods, a Concentrator for ore processing, and Copper and Gold production for export to Chinese smelters. The mine transitioned from open-pit to underground extraction as its primary mining method, with production ramping up significantly in recent years.

Products and services

• Open Pit Mining Surface mining operation accessing the Southern Oyu deposit at approximately 100,000 tonnes per day, with around 560 workers in 12-hour shifts. Trucks transport approximately 290 tonnes of excavated soil and ore to stockpiles or the primary crusher for processing.
• Underground Mining Underground block caving mining operation representing the transition from open-pit to underground extraction methods to access deeper ore deposits. Block caving is one of the most productive underground mining methods and is being used to sustain long-term copper and gold production.
• Concentrator Operations On-site ore processing facility that crushes and processes mined ore to produce copper and gold concentrates for export to smelters, primarily in China.
• Copper and Gold Concentrate Production Production of copper concentrate and gold as the primary commodities from the Oyu Tolgoi deposit, one of the world's largest known copper-gold deposits. Output is exported to Chinese smelters that process the concentrate into refined copper for use in electrical wiring, EVs, AI data center infrastructure, and renewable energy.

• Entrée Resources Ltd.minorStrategic or Co-development Partner · 9 April 2026Entrée Resources is a joint venture partner with Oyu Tolgoi LLC for the Shivee Tolgoi and Javkhlant mining licenses. The company is focused on transferring these licenses necessary for underground development and has delivered a non-binding proposal offering a negotiated royalty payment instead of 34% equity participation. Drill results from Hugo North Extension deposit showed 124m at 3.41% CuEq.
• NGO Partners (Gerelt Project)minorStrategic or Co-development Partner · 1 January 2020Oyu Tolgoi collaborates with NGOs on the 'Gerelt' mental and reproductive health project for adolescents, now in its fifth year. The project established psychological counseling rooms, health and sport clubs at remote schools, benefiting 17 schools with plans to expand to four more schools in Bayanzurkh district.
• Munkh Nogoon Galba NGO (Mongolia)minorStrategic or Co-development Partner · 1 January 2018Local NGO established by soum residents and herders implementing environmental monitoring projects since 2018, covering water resources, soil degradation, pasture, wildlife, air quality, and ecological education for youth.

Direct peers

• Escondida: The world's largest copper mine, operated by BHP (57.5%) and Rio Tinto (30%) in Chile. Directly comparable as a large open-pit copper operation owned jointly by Rio Tinto, with similar scale, copper-concentrate output, and joint venture ownership dynamics to Oyu Tolgoi.
• Grasberg Minerals District: Freeport-McMoRan's flagship copper-gold operation in Indonesia, transitioning from open-pit to underground block caving. Highly comparable to OT given the copper-gold co-product mix, block-cave underground transition, and export-logistics complexity to remote Asian smelters.
• Collahuasi: Major copper mine in northern Chile operated by Glencore and Anglo American. Comparable as one of the world's largest copper producers with copper-concentrate exports and similar large-scale open-pit operations supplying Asian smelters.
• Los Pelambres: Antofagasta PLC's large-scale copper mine in Chile. Comparable as a top-tier global copper concentrate producer with a similar production profile and end-market exposure to Asian smelters.
• Las Bambas: MMG's large copper mine in Peru, one of the world's largest copper operations. Comparable as a major copper-concentrate producer that has faced significant community and political disruption risks, analogous to OT's single-route and political exposures.
• Bingham Canyon (Rio Tinto Kennecott): Rio Tinto's Utah copper-gold-molybdenum operation, one of the largest open-pit mines in the world. Directly comparable as a Rio Tinto-operated large-scale copper operation with gold byproduct and similar parent-company technical/operational backing.
• Chuquicamata (Codelco): Codelco's flagship copper mine in Chile undergoing an underground block caving transition. Highly comparable to OT in transitioning from open-pit to underground block caving extraction and operating at very large scale.
• El Teniente (Codelco): The world's largest underground copper mine, operated by Codelco in Chile using block caving. Highly comparable as a benchmark underground block-cave copper operation informing OT's own underground transition.
• Resolution Copper (Rio Tinto/BHP): Major undeveloped copper project in Arizona jointly owned by Rio Tinto and BHP. Comparable as a large-scale, deep-block-cave copper project within Rio Tinto's portfolio with multi-decade production potential similar to OT's underground phase.

Emerging players

• Panguna (Bougainville Copper): Historically major copper-gold mine in Papua New Guinea being reopened. Comparable to OT as a large copper-gold operation with significant political and community-relations risk profile in a developing jurisdiction.
