The contract has total value of $307,000 and annual recurring revenue of $154,000.
Under the contract scope Rocketmine will carry out monthly aerial surveying of ore stocks, the tailings storage facility and other infrastructure as required, using a dedicated on-site drone specialist.
Delta Drone chief executive officer Christopher Clark said it was pleasing to have converted AngloGold Ashanti from a regular project-based customer to a multi-year term partnership.
"AngloGold Ashanti will immediately benefit from our long-range beyond visual line-of-sight and above 400ft approvals, allowing us to capture and process all their geospatial requirements more quickly and efficiently," he said.
"This contract also contributes to the growth of our annual recurring revenue, which is a key metric investors use to value our company and its future revenue potential."
