Abstract The Roy Lloyd Mine in northern Saskatchewan is a high-grade underground gold mine which is currently supplying ore to Golden Band Resources’ Jolu mill. Prior to the operation of the mine an underground exploration program was conducted intermittently at the site. During both the underground exploration phase and mining, Golden Band Resources (Golden Band) has been investigated ways to reduce freshwater usage within the mine by recycling mine water.
Golden Band initiated an underground exploration program at the Roy Lloyd mine site (formerly called the Bingo Project) in October 2007 to better delineate the mineralization of the Bingo gold deposit. The exploration program provided geological information required in order to improve the confidence level of the geological resource model and also provided information to aid in the mining of the deposit, such as the determination of groundwater inflow rates. Underground mining started in March 2011.
This paper provides an overview of the mine water recycling methods attempted at the site during both the exploration and initial mining phases of the project, and the success/drawbacks of these measures to date. The paper will also discuss options that are currently being evaluated in order to further improve Golden Band’s ability to recycle water while reducing chemical additive costs.
