Mining and Milling at Dome, Hollinger, and McIntyre

THE Dome ore-bodies are more or less isolated and are mined. by shrinkage stoping. An interwoven system of veins is mined at Hollinger and requires close filling. Deep mining is the problem at McIntyre. Dome ore contains a large amount of free gold, which is recovered on blankets. An all-cyanide flow-sheet is used in the Hollinger mill. Flotation concentration is an important feature of McIntyre mill operation. Therefore, these three mines afford an unusual opportunity to compare gold mining and milling methods.
