During development and production phases of a project, mine managers can use the Reconciliation plays an important role in closing the design loop: assessing performance, enabling the identification and action plan of key learnings, and identifying deficiencies or new efficiencies in the process. Geotechnical engineers play a pivotal role in reconciliation and require this step in the process to improve upon geotechnical recommendations and designs, to verify initial assumptions are correct and relevant, and ultimately to reduce uncertainty. Since reconciliation activities are backward looking, and don’t add immediate value to the schedule, they're often sidelined when resources are light, or skipped all together. Omitting this key activity, especially from a geotechnical perspective, can have significant consequences and result in missed opportunities. Just imagine all the geotechnical uncertainties from a historical design conservatively balanced into a recommendation that continues to be implemented by a site that doesn’t have adequate geotechnical support to audit, verify, optimise, and monitor all aspects of that design against the ground and support performance; how much lost efficiency and revenue that can amount to?
The 2 October RNS is emphatically a failed geotechnical assessment imop. The company was operating to older engineering designs to July 2023. At some point in late July a new geotechnical assessment was possibly started and by late September some drastic mistakes will have been discovered or alternatively Marino requested the information and discovered the problems himself. Hence why scopes changed, more earth works needed and additional interface equipment was required. A failed geotechnical model to occur has a lot to do with the lack of availability of that skill set within the construction team until it was to late. Hence why the CEO and some Board members had to go. The time to prevent such an error was back in May 2023 and was missed imop as other work items were given higher priority.
