Since mid-2016 Rio Tinto’s Oyu Tolgoi mine in Mongolia have been using the Leapfrog Central model management platform to track changes in the long and short term resource models for the open pit.

Oyu Tolgoi is one of the world’s largest known copper and gold deposits and is expected to operate for over 50 more years. The deposits at Oyu Tolgoi are huge, with seven geologists working on the modelling of the Open Pit.

Rio Tinto’s onsite Geology Manager, Otgonbayar (Oggy) Togtokhbayar says, “We upload and store our models in Leapfrog Central, enabling us to work on models and conduct our peer review from different locations. Using Leapfrog Central as a control point not only makes us more efficient, but it also allows us to easily interact and collaborate as a wider team.”

Models are built in Leapfrog Geo and published to Leapfrog Central, where geologists can discuss, hypothesise and add annotations to areas which
need focus and reinterpretation. Managers can look back over model development visually and see how decisions are being made.

Continues Oggy, “Before Central we were struggling to keep track of up-to-date models. Now we can easily identify the latest version and see who has modified it and why, enabling us to easily track evolution.”
