Jack Hills - Wikipedia

Detrital zircons with ages greater than 4 billion years old have been found in these rocks, and a 4,404 +/-8 million year old zircon was found at Erawandoo Hill; this is the oldest dated material originating on Earth; the date is in the Cryptic era of the Hadean eon. They were found within a unit of the supracrustal sequence, a metamorphosed conglomerate considered to have an age ~3.0 Ga.

When mining began published ore reserves were 3.8 m tonnes at 9.6 g Au/tonne, and at the end of 1979 reserves were 3.9 m tonnes at 8.6 g Au/tonne. The initial output from the mine increased Australias gold production by about fifty percent, and made Telfer the largest single gold mine in the country (Australian Financial Review, 23 Nov. 1978). 1
