The gold and copper miner reported net profit of $862 million and free cash flow of $737 million for the year to 30 June, its first full financial year owning the Telfer operation.
The incoming chief operating officer brings 25 years of large-scale underground mining experience, including senior roles at Northern Star and Newcrest, as Greatland advances its Telfer-Havieron hub.
The AIM and ASX-listed gold producer delivered full-year gold production 6% above the top end of its guidance range, while cash on hand grew to $1.29 billion with no debt.
A 240,000-metre drill campaign has driven a 150% increase in Telfer's ore reserve, lifting Greatland's group total to 5.0 million ounces of gold.
"The development of Havieron, alongside the successful delivery of Telfer life extensions, has the potential to underpin a multi‑decade, world class gold‑copper mining hub in the Paterson Province," said Shaun Day, Managing Director.
"Once in steady state Havieron is anticipated to produce around 270koz of gold per annum at lowest quartile costs, with an initial mine life of 17 years," Greatland Managing Director Shaun Day said.
The gold miner reported a step-out diamond hole at the Pinnacles prospect returned 58.7m @ 6.5g/t gold and 0.1% copper from 1,754m, indicating a possible southern extension of the West Dome Underground (WDU) geological structure.
The gold miner expects full-year production to be around, or slightly above, the upper end of 260,000-310,000oz after the March quarter delivered a $260m cash build.
