Premier Gold Mine is a Canadian mining company that owns various properties around the world. Notably, the company acquired the project Cove – McCoy, a property previously operated by Newmont Gold. However, the mine was closed because of water infiltration was too high. According to the records, it would require a pumping rate between 15 000 and 20 000usgpm to ensure dewatering of the pit.
In 2014, our firm has conducted a preliminary analysis of dewatering, by partnering with Technosub company. Various scenarios have been considered, namely the addition of pumping wells, or the possibility of cementing to reduce infiltration.
Pumping costs were defined and Premier Gold Mine is now working to confirm the reserves before starting dewatering the pit.
