Overview
Savannah aimed to recommence operations at the Georgetown processing plant, and GeoTails Consulting was engaged to assist in selecting a Tailings Storage Facility (TSF) to accommodate the forecasted Life of Mine (LoM) tailings production. GeoTails collaborated closely with the client to develop two tailings disposal options: conventional slurry tailings and dry-stack tailings. Additionally, GeoTails provided the necessary documentation to support the site's Environmental Authority (EA) amendment process, ensuring compliance and regulatory approval.
Challenge
The primary challenge was navigating the constraints of the project, which included a limited area within the site’s mine lease for the TSF footprint and high-water demand in a dry climate. Selecting a viable TSF strategy that supports both short-term needs and Life of Mine (LoM) operations was complicated by these site-specific limitations. Balancing the efficient use of space, optimizing water management, and ensuring long-term operational viability required careful planning and innovative solutions.
Solution
To address the Life of Mine (LoM) tailings production and project constraints, two TSF options were designed: conventional slurry tailings and dry-stack tailings. These designs were optimized to fit within the limited footprint and address water demand challenges in the dry climate. To support regulatory approval and align with the client's priorities, a qualitative assessment was conducted using a set of key criteria. This structured approach helped the client in the decision-making process by evaluating key risks, benefits, and trade-offs associated with each tailings management option, ensuring the selection of the most suitable solution for both short-term and LoM needs.
