A major integrated Underground Mine and Concentrator producing Zinc Concentrate had consistently underperformed against budget for four consecutive years.
Despite significant operational effort, financial performance remained below expectations eroding margins, limiting reinvestment capacity, and increasing leadership pressure to deliver sustainable improvement.
An assessment of the site’s Management Operating System (MOS) revealed that the root cause was not technical capability but execution discipline and system integration.
Strategic priorities were not translated into clear, measurable targets at operational and frontline levels. Accountability was unclear and teams lacked visibility on how daily work connected to site-wide performance.
Short-range forecasts, weekly plans, and daily schedules, particularly in Mining, were misaligned. This created rework, inefficient resource utilisation, and variability in ore supply to the concentrator, directly impacting throughput stability.
Metrics and review routines varied across functions, creating multiple versions of the “truth.” Problem-solving was reactive, with limited cross-functional transparency.
Daily, weekly, and monthly reviews were largely backward-looking. Root causes were not systematically addressed, and corrective actions lacked ownership and follow-through.
Collectively, these systemic weaknesses reduced execution discipline, increased performance variability, and constrained the organisation’s ability to sustainably close performance gaps.
The site was working hard but not working as one integrated system.
From disconnected goals to aligned execution
From siloed planning to 3-month horizon integrated planning
The site began operating as one value chain not separate departments.
From reactive reporting to forward-looking execution control
Problem-solving shifted from explaining variance to preventing it.
9-month, wave-based deployment delivered shoulder-to-shoulder with site leadership and front line teams.
The focus was to build capability and ensure sustainable behavioural change.
Performance gains were sustained beyond implementation, restoring execution discipline and predictability across the operation.
Sustained overperformance achieving record production
Record monthly performance and achieve best Half-Year results.
Best Half-Year results.
Performance improvements are measured against the 18-month period prior to MOS deployment. Reported results reflect sustained performance achieved over the last six months.
The implementation of a disciplined fit-for-purpose MOS delivered measurable production uplift and a fundamental shift in execution culture.
