The search for precious metals sometimes takes mining prospectors into remote and hostile environments. These environments come with many operational, environmental, social and cultural challenges. For instance, identifying a mineral-rich area that is very deep requires installing underground facilities to optimize mineral extraction. Installing a network of shafts, tunnels and drifts creates drainage conduits for groundwater. What’s more, permafrost thawing is accelerated by heating in the work areas. The areas natural groundwater is unusually highly saline. Finally, groundwater carries a low quantity of ammonia nitrogen ensuing from explosives. Each of these challenges was a factor for this mining operation in Northern Canada.
