Sandvik, Rio Tinto team up on open‑pit autonomous drilling
Sandvik and Rio Tinto have partnered to advance open-pit autonomous drilling, combining Rio Tinto’s expertise in autonomous drilling systems (ADS) and remote operations with Sandvik’s AutoMine automation technology. The collaboration aims to accelerate the deployment of fully autonomous drill rigs in Rio Tinto’s open-pit mines, potentially reducing operational costs by up to 15% and improving safety by removing personnel from hazardous zones. This matters as it sets a new industry benchmark for automation in mining, leveraging the strengths of a top equipment supplier and a major miner to drive efficiency and productivity in an era of labor shortages and rising demand for critical minerals.
In a landmark move that underscores the mining industry’s accelerating shift toward digitalization and automation, Sandvik and Rio Tinto have announced a strategic partnership to collaborate on open-pit autonomous drilling. The agreement, which brings together two of the sector’s most influential players, is set to transform how blast-hole drilling is performed at large-scale open-pit operations globally. Rio Tinto, already a pioneer in autonomous haulage and drilling systems (ADS) at its Pilbara iron ore mines in Western Australia, will combine its extensive remote operations experience with Sandvik’s flagship AutoMine automation platform—a system already proven in underground and surface drilling applications. The partnership will focus on developing and deploying fully autonomous drill rigs that can operate 24/7 with minimal human intervention, targeting a significant reduction in drilling cycle times and an improvement in overall fleet utilization by up to 20%.
This collaboration arrives at a critical juncture for the mining industry, which is grappling with rising operational costs, labor shortages, and the need to boost productivity to meet surging demand for raw materials—from iron ore and copper to lithium and other battery metals. Autonomous drilling is seen as a low-hanging fruit in the automation ladder, as it is relatively less complex than autonomous haulage or loading, yet offers substantial safety and efficiency gains. By removing drill operators from the immediate vicinity of active machinery, the risk of injuries from falling rocks, noise, and dust is drastically reduced. Moreover, autonomous systems can drill with higher precision, leading to better fragmentation in blasting and lower downstream processing costs. According to industry estimates, automation of drilling can reduce operational costs by 10–15% and improve drill pattern accuracy by over 30%, translating into millions of dollars in savings for large mines.
The Sandvik-Rio Tinto partnership is not the first of its kind but is noteworthy for its scale and scope. Rio Tinto has been operating autonomous drills at its Pilbara operations since 2019, with a fleet of over 20 rigs running on its ADS system, which was developed in-house with suppliers. However, the company has recognized that to scale these capabilities globally and across different commodity types, it needs to leverage standardized, proven automation platforms like Sandvik’s AutoMine. Sandvik, for its part, will benefit from Rio Tinto’s real-world data and operational feedback, allowing it to refine its technology for challenging open-pit environments with extreme temperatures, dust, and variable rock conditions. The two companies have emphasized that the partnership will be open to co-development of new hardware and software innovations, including the integration of artificial intelligence for predictive maintenance and real-time ore grade control.
From a market perspective, this deal could catalyze wider adoption of autonomous drilling across the mining industry, which has been slower to automate than other heavy industries like logistics or agriculture. Currently, only an estimated 5–10% of global open-pit drilling operations are fully autonomous, with the majority relying on semi-automated or manual systems. As mining companies face increasing pressure to decarbonize and improve safety, partnerships like this—combining a top-tier OEM with a major miner—provide a blueprint for rapid technology deployment. Analysts predict that the global mining automation market will grow at a compound annual growth rate (CAGR) of over 12% through 2030, with autonomous drilling representing a key segment. For Sandvik, this partnership strengthens its position in the surface drilling equipment market, which it dominates alongside competitors like Epiroc and Caterpillar. For Rio Tinto, it ensures that its operations remain at the forefront of efficiency and safety, critical for maintaining margins in a volatile commodity price environment.
Looking ahead, the success of the Sandvik-Rio Tinto collaboration could have ripple effects across the supply chain. It may prompt other majors—such as BHP, Vale, or Anglo American—to pursue similar bindings with automation vendors, accelerating the shift toward fully autonomous open-pit mines. Additionally, the technological advancements generated from this partnership will likely trickle down to smaller mining and exploration companies, making autonomous drilling more accessible and affordable over time. In summary, this deal is more than just a vendor-client relationship; it is a strategic alliance that will shape the future of mining automation, with the potential to redefine productivity standards in an industry that is rapidly embracing the digital age.
