A gravel quarry on top of Lavers Hill, which is located 4km E of Fish Creek and 160km SE of Melbourne in South Gippsland, has produced a range of phosphate minerals. Turquoise had been known to occur in 4 separate localities in the area since 1925.
"In 1966 investigations were concentrated near Lavers Hill where beds of phosphatic breccia yielding assays of up to 19.7 wt. % P2O5 were exposed by trenching. However the area was not considered economic. The quarry on the top of Lavers Hill, (which is run by the local council) exposes a sequence of thinly bedded cherts and shales, strongly crushed and faulted in places, and dipping steeply ENE with northwest strike. A prominent band of dark grey to black phosphatic breccia, up to 2 m thick, contains subangular to rounded cherty fragments in a fine-grained matrix, together with fragments of pyrite and veinlets of wavellite. The breccia weathers to a pale grey, with some of the fragments becoming bright green and clay-like; these have been confirmed as glauconite. Phosphate minerals also occur in cavities and seams along joint planes in the adjoining cherts."
