Re: How deep is too deep

I know Macassa Mine is not as deep as some but it is close by in KirkalndLake.

This info is a little dated but still interesting.

Macassa # 3 shaft (Kirkland Lake ) at 7239 feet deep became the deepest single-lift mine shaft in the Western Hemisphere when it bypassed the 7,173 ft Creighton #9 shaft in 1986 & held the record for 14 years, until the LaRonde #3 shaft was sunk deeper to 7,380 ft in early 2,000. Macassa #3 shaft still holds the world record as the deepest single-lift timbered shaft in the world
