Ragland Mine, located in Katinniq north of the 61st parallel, operates a base metal deposit (copper, nickel, some platinum group elements). The operations were confined in permafrost for several years, resulting in near absent water inflow issues. However, some recent drilling intercepted significant water flow to a depth of about 600 m, while some others even showed gushing artesian conditions. Also, water infiltration and observations of gas in a portion of the mine are new phenomena in Ragland.
Hydro Resources was mandated to characterize the aquifer and identify the flow zones and other hydrogeological issues to enable Ragland Mine to know the risks and develop mitigation means to operate in depth under permafrost.
