There was a quarry on the property, which provided iron ore from around 1899, for use as flux at the Cockle Creek Smelter. Later and more significantly, it provided ore—around 500,000 tons—for the Lithgow Blast Furnace, from late April 1907 up to May 1923, when the lease expired and was not renewed. This second ore mining operation included a railway line, 1¼ miles in length, connecting the quarry to the Blayney–Demondrille railway line south of Carcoar. The iron ore quarry was located south of Coombing Creek and just west of modern-day Fell Timber Road. The formation of the former railway line remains discernible in aerial views.
