Mine Life Cycle Analysis, Cyprus Tohono Mine
As part of the Tohono Mine Life Cycle Analysis, Integral staff used hydrologic and environmental systems analysis (HESA) to assist resource economists in an evaluation of future mining operations and site closure strategies. Integral staff developed a conceptual site model (CSM) to understand the land surface, surface water, and groundwater systems for the Tohono mine area as one integrated system and as subsystems relating to specific mine site features. Integral staff also supported use of the CSM with quantitative decision analysis to develop alternate technical and economic scenarios. Specific tasks included evaluating, in the context of the surface- and groundwater systems, expanded mining in a lease area, closure of a nearby lease area, restoration of evaporation ponds and mine tailings areas, cleanup of separate sulfate and uranium groundwater plumes, and closure of the main mine site.
HESA provided the regional and site specific CSMs that enabled the economists to develop multiple input strategies into the quantitative decision analysis. In addition, the systems-based CSMs reduced unnecessary data collection and analysis and enabled the design of more cost-effective remedial solutions that incorporated pollution prevention strategies and assisted in resolving groundwater compliance issues.
This project reflects Integral staff experience gained under previous employment.
