Described as a large low grade orebody containing gold. Located at Lennonvale or Five Mile, its distance north from Mount Magnet. The mine was opened in 1895 by Irishman Bignell (surname), and the mine was possibly named after a mountain peak in Ireland. He was in partnership with Harry Dew, and another we know only as Heazler (surname). In 1902 the mine was sold to J.V. Kearney from the nearby Wheel of Fortune mine. Large tonnages were shifted from the mine through the state battery from this time till around the outbreak of World War One.
In 1922 it was noted the mine was operated by Ruggeri, Moderana and Pozzi. In 1935 the Galtee More Gold Mining Company was floated to take over mining operations at Galtee More and nearby Drumoyne and Empress mines. It notes the Grose Brothers had worked the mine profitably for many years, and one of them still holds it. Another source states a Dr C Grose took over the 'old' Galtee More mine in 1938, and crushings were noted from C Grose and party in 1940.
Mining also took place between 1985-1989 but no further details are known.
The ore is hosted by the Warramboo Unit of chert and chert breccia, overlying a thin basal horizon of black shale, minor felsic flows, and tuffs. Thinly layered interbedded chert-hematite and chert magnetite occurs in the unit, and includes minor shale and graphitic shale. Chert breccia is variable in its distribution, shows folding, slumping and brecciation. Gold is found in disseminated chlorite and massive pyrrhotite/pyrite zones in local cross faulting areas within the chert/banded iron formation host.
