CEEC International and Whittle Consulting have reached the mid-point in their Neo-Marvin case study, a collaborative initiative under the Global Water Initiative (GWI). Designed to model and test innovative water supply and tailings management strategies and integrate water considerations into mine optimisation processes. 

Neo-Marvin is an advanced, customisable copper orebody model, and when coupled with Whittle’s Prober optimisation software, enables the evaluation of scenarios such as groundwater, seawater, and desalinated water sources in combination with various tailings dewatering technologies, including thickening, filtration, and tailings stacking. The study also extends to the impacts of geographic and climatic variables, such as altitude and proximity to water sources, to assess economic and environmental trade-offs comprehensively. 

"We’re thrilled to see how this project is unfolding," said Laurie Reemeyer, CEEC International Advocate and Project Lead for the case study. "The first phase has focused on the model setup and preliminary insights, while laying the foundation for exploring second-order effects. These including how water-related costs influence orebody definition, economics, pit shapes, and operational strategies. This approach bridges the gap between hydrology and mine planning, offering a blueprint for more sustainable mining practices." 

Key Findings & Next Steps

Preliminary results highlight the significant influence of water sourcing and tailings technologies on operational costs and mine design. Future phases will refine optimisation methodologies, further evaluate second-order effects, and integrate broader sustainability metrics, such as social and environmental impacts. 

Whittle Consulting’s contributions, coupled with sponsorships from key partners such as Agnico Eagle and Weir, have been instrumental in advancing this work. The collaboration has also benefitted from insights drawn from earlier, first-order studies and industry best practices, ensuring a robust and scalable model for application across diverse mining contexts. 

Global Relevance and Future Vision

This study comes at a pivotal time as mining operations worldwide face increasing pressure to adopt sustainable practices. The outcomes of the Neo-Marvin case study are expected to provide actionable insights for the global resources community, supporting the shift towards eco-efficient mineral production. 

Janine Herzig, Executive President & Director at CEEC International, expressed her gratitude to sponsors and collaborators: "This initiative exemplifies the power of collaboration in addressing critical industry challenges. With support from partners like Whittle Consulting, CEEC continues to pave the way for sustainable and resilient mining practices that balance economic prosperity with environmental stewardship and positive social impact."
