Exploring for critical minerals is an expensive endeavour, with global expenditures reaching $12 to $13 billion in 2023. Mining remains a high-risk venture, as only about three out of every 1,000 exploration attempts lead to actual deposits. Despite employing advanced geological models, companies must still drill deep to collect rock cores and validate their predictions.
Ted Feldmann, founder and CEO of Durin, highlights the hefty costs associated with drilling, which can consume up to 70% of the capital raised by exploration firms. The traditionally labour-intensive nature of drilling means that around 60% of expenses are tied to payroll, and the shortage of qualified drillers in the United States has compounded the issue. Typically, drilling operations require two to three personnel on-site to manage equipment and interpret geological data by assessing sounds and gauges.
To tackle this challenge, Feldmann is integrating robotics with drilling technology to reduce costs. Durin has secured $3.4 million in pre-seed funding, aimed at developing more efficient drilling rigs. The company’s initial rig design can drill down to 300 meters and is equipped with sensors to gather data that will facilitate the automation process in the future.
Though the first rig remains manually operated, Durin is also creating systems to automate the loading of pipe as drilling progresses. The startup plans to initiate its first drilling programme and anticipates that by year-end, it will gather sufficient data to further its automation efforts. Feldmann envisions a future where rigs can operate with minimal human oversight, although personnel will still be necessary to provide supplies, monitor operations, and collect core samples.
Feldmann’s goal is to eliminate the need for workers to stand by the rig while it operates, ushering in a new era of automated drilling that could significantly lower costs and increase efficiency in the critical minerals industry.
