Located 175 kilometres north-west of Meekatharra, and 1.5 kilometres north north-east of Mount Seabrook. It is the second largest talc mine in Western Australia, after the Three Springs mine.
Discovered in 1965 by prospector M. Lalor, then pegged 1969 by A. Doust. This was later purchased by the Lalor Prospectors Syndicate, then acquired by Westside Mines NL, who opened an exploration pit across 1969 to 1972. Production followed 1973-1984 achieving 230 842 tonnes of talc. The mine was purchased by Thames Mining NL 1986-1987, then Gwalia Minerals NL. The mine is operated at present by Imi Fabi (Aust) Pty Ltd. Nearly all the talc is exported from Geraldton to Europe for high grade applications.
Numerous talc deposits are found in the Mount Seabrook-Livingstone Belt hosted by the Paleoproterozoic Padbury Group. The talc was formed by metamorphism of dolomite forming part of a schist-dolomite-chert-quartzite-talc sequence, intruded by granite of the Moorarie Supersuite.
The country rock is metamorphosed sandstone, dolomite, quartzite, pebble conglomerate, and quartz-muscovite schist, together with biotite and chlorite bearing lenses of white to light green contorted talc schist.
The talc is fine grained, white to pale green, locally translucent, massive to weakly foliated, with minor rounded and anhedral quartz, and veinlets of fine common opal, with talc developed as steeply dipping lenses within dolomite. Granite at the eastern side of the mined area has intruded the dolomite-quartzite-talc unit.
It is thought the talc developed by the alteration of sandy dolomitic rocks by hydrous metamorphism at temperatures between 200 and 250 degrees C.
