A modelling study of the South Bay Mine site / report prepared for Boojum Research Ltd.

Abstract

The three basic objectives of the Phase one modelling described in this report were the following: - Develop a global site-wide model encompassing all of the significant water sheds in the vicinity of the site in order to determine the effective dilution via groundwater of contaminated water with water from uncontaminated areas. This can then be used together with measured surface water flows to determine expected contaminant concentrations in various water bodies. -Use the results of the global site-wide model to construct a more detailed tailings area model and calibrate this model to simulate the measured existing flow patterns. -Use the detailed tailings area model to simulate the release and transport of contaminants from the tailings area into the various receiving water bodies. As stated above, two models were developed for this study, a global site-wide model and a more detailed tailings area model. The major input parameters required by both of the models are summarized in Chapter 2 and the development and results of the global site-wide model are described in Chapter 3. The development and results of the failings area model are given in Chapter 4. Conclusions and recommendations for further work are given in Chapter 5.
