Excelsior Colliery
Excelsior No. 1
Excelsior No. 2
Excelsior B

Excelsior No. 1 mine was opened by J. S. Kirton in 1900. Located just north of Bulli Pass, its product was natural coke and coal in near equal proportions, the coal selling locally.

Excelsior No. 2 was opened in 1905 by Ryan. Located immediately under the Bulli Lookout and in good coal just north of the northernmost part of the Bulli cinder belt.

The mines together eventually became Excelsior Colliery with limited output in the initial few years.

(Opened in 1905 by Carroll & Ryan, selling to Kirton & Earnshaw after 8 months)
