About Ben

His specialist expertise lies in geological modelling, pit optimisation, mine planning, and scheduling. A proven problem solver, Ben has been regularly called on during his career to lead the design and implementation of mine planning systems and customised software solutions to some of the world’s largest and most complex mining “operations.

Ben manages a team of engineers and geologists out of Xenith’s Sydney office. He also devotes considerable time to upskilling the industry’s next generation as the leader of training and development for the engineering team. Ben initiated toolbox sessions for information sharing at Xenith and presents internal sessions on the JORC Code for the reporting of Mineral Resources and Reserves.

He is passionate about adding value to projects, identifying the key drivers in a deposit and unlocking the best path to realise the project’s potential. He also gets great satisfaction out of business development, bringing in new clients and mentoring junior staff.
