A large contractor from Dubreuilville actually built the road to Magnicon Mine where the current mill is now, back around 1985 with all blasted rock. Road was solid still after I restarted the generators in 1994 or so. Once the Eagle River mine got going full tilt, they sunk a shaft and lots of new people use to come on site. Pioneer came in after that along with lots of different contractors over the years.
Been running about 30 years straight now.
With gold super high in price, lots of low grade areas are being mined to mix with high grade. If they send too high of grade into the mill they will lose it out to tailings. Never want big gushes of high grade or it will be lost. That is why they even mix super low grade from a pit to offset the high grade and still make lots of money. that is my experience.
