Mine was formed from some of
 Maurice Hawkinson's leases in 1929

 Harry N. Freeman was Manager
Part of the Big Six at the time of Sept 29, 1931 Riot.

6th largest Deep Seam type mine in 1931

Located between Eastern Mine and Crescent Mine,
North of Highway 39, 1 1/4 miles west of Bienfait.

During the 1931 strike, this mine was actually the best of the Big 6.
They seemed to be running a safer mine,
and had at least a little concern for the miners.
Like all the Big 6, they didn't want to see a Union at the mine.

Harry Neville Freeman, who was a Mining Engineer,
who specialized in Coal Mining, and its by products,
gave a speech on coal mining in BC, in Dec 1928. 
He would have known Harry Stevens there.

1909 he was an underground foreman
 at the South Wellington Mine, near Nanaimo.
He was seriously injured from a fall of coal,
and this might have been the close safety call,
that made him care for safety at this mine more than others.

In 1913 he was Manager of the Jingle Pot Mine in Nanaimo
and was an outcast among other managers when he
was one of the first mines to acknowledge a Union at Nanaimo.
