In the early 1980s, Turcaud reached a settlement, accepting $25,000 from Newmont's head office in New York City but continued his claim, demanding a Royal Commission.

[4][10] The official story of the discovery states that the deposit was found by Day Dawn Minerals, a small exploration company, who did not stake a claim either.

The closure of the mine came one year ahead of schedule as production of underground ore was well below mill capacity and therefore not viable.

[9] High production costs were primarily caused by the presence of cyanide soluble copper in the open pit ore.[12] Newcrest then focused on exploratory drilling for new minerals.

[16] The redevelopment expanded underground mining areas, deepened open pits, constructed a processing plant and power station, and built a new gas supply line from Port Hedland.

Newcrest said, "At Telfer, mechanical availability of the open pit mining fleet and the processing of harder ores are impacting the expected production profile for the full year.

"[20] In June, the mine was affected by the statewide gas crisis caused by an explosion at Varanus Island.
