Long Lake Joint Venture
Project HistoryProject History
Several small hydro schemes powered the Premier and Big Missouri mines during 1923 through 1956
Developments on lower Cascade & Fletcher Creeks provided power to nearby Premier mine and townsite

Project HistoryProject History
Cominco built dam at Long Lake to provide 8500 dam3storage for Big Missouri mine power development
Provided firm power of approx. 1000 kW year round to mine and townsite
Long Lake Concrete Arch Dam:length - 30 m height - 12 m

Project BackgroundProject Background
Westmin studied Long Lake hydro scheme to service new 2000 tpd mine in late 1980’sPlans for 7.5 MW hydro power plant shelved when BC Hydro extended transmission line from Aiyansh to StewartPremier Gold mine operated until mid 1990’sMine is presently executing closure plant, Boliden seeking to dispose of property
-
Long Lake Joint Venture
Development BackgroundDevelopment BackgroundIn 1999, Premier Power entered into Agreement with Boliden to acquire facilities & infrastructure, rights-of-way, roads, etc. for Long Lake small hydro development– Provides Boliden cost relief,
additional security of supply for ongoing water treatment obligations
Late 2002: Premier Power and Regional Power formed Long Lake Joint Venture to advance the developmentSuccessfully bid into BC Hydro’s2002 CBG power acquisition program and executed EPA in spring 2003
