How Petra Diamonds saved millions on ore pass remediation using autonomous drone technology

Emesent Hovermap technology helps Petra Diamonds assess ore pass damage within hours.

In October 2019 Petra Diamonds was faced with a decision to repair or abandon an orepass which had suffered damage from long-term scaling.

Faced with the potential of costly remediation work that may not succeed, management tasked Emesent partner Dwyka Mining Services with providing accurate, quick and cost-effective visualizations, without endangering the safety of Petra personnel or contractors.

Learn how Hovermap scanning technology helped cement the decision to abandon costly remediation plans, saving Petra an estimated five months and five million rand.
