KCGM is set to pour its 20 millionth ounce, and the 60-millionth ounce on the Golden Mile, virtually 124 years to the day after Paddy Hannan, Tom Flanagan and Dan Shea struck it lucky at Mt Charlotte.
Coming just weeks after last Thursday’s opening of the Cassidy Centre — which underground workers and office staff will occupy until at least 2021 after resource extensions at the Mt Charlotte underground mine — the Hannans North Tourist Mine will host a community day on June 17 to celebrate the day Mr Hannan registered the original Kalgoorlie claim at Coolgardie.
KCGM will also be producing a 1oz silver medallion with 24-carat gold gilding through the Perth Mint to commemorate the occasion.
The Golden Mile, sometimes referred to as the richest square mile on Earth, was originally located from Hannan’s Brownhill south through Lake View to Chaffers.
It was eventually extended to Croesus at the north and Hannan’s Star at the south, about 3.8km in length, not including the Mt Charlotte.
The Super Pit, currently half-owned by Barrick and Newmont, was first formed when Alan Bond amalgamated the old leases of the Golden Mile in the 1980s.
Opening in 1989, the pit has been through 14 cutbacks and now measures 3.5km long by 1.5km wide and 600m deep.
KCGM produced 764,000oz last year at an average mined grade of 1.92g/t, still strong, although not as high as the Golden Mile’s production record of 1.2m ounces at 34.4g/t in 1903.
The life of the pit has been extended to 2025, with stockpiles to be processed for at least 10 years afterwards.
Last Thursday, dignitaries attended the official opening of the Cassidy Centre office block, completed at a cost of about $500,000.
As part of its new lease on life, underground workers have returned to the Cassidy shaft, sunk in 1985. Powered by a classic friction winder, it transports up to 54 workers at a time at a rate of 4.5m a second but can reach a maximum rate of 9m/s.
