The Tulsequah Chief project is located on the Tulsequah River in northwestern British Columbia. The property is located 100 kilometres south of the town of Atlin, BC.
Tulsequah Chief's capital requirement is estimated at Can$ 201.5 M., with a probable reserve of 5.4 M
The process plant will operate at 2,000 tonnes per day. Ore will be crushed in two stages - a 750 mm x 1000 mm jaw crusher, followed by a cone crusher. Grinding will be done in a two-stage rod and ball mill grinding circuit. Gold concentrate will be separated using a gravity circuit. An on-site refinery will be used to produce gold bullion. Any bulk copper-lead flotation concentrate produced will then be separated into copper and lead concentrates. Zinc concentrate will then be separated. Concentrates will be dewatered by pressure filtration to achieve a moisture content of 8% prior to shipping.
Tailings will be separated by a final stage of floatation, removing the pyrite to reduce the sulphide content. The pyrite will be mixed with inert tailings and cement then pumped underground as paste backfill. Neutral tailings will be mixed with limestone and sent to the tailings pond. Limestone will be added to the tailings to ensure there is no potential for acid generation. The limestone will be quarried, crushed and milled on site.
