Greatland Resources Ltd. (GGP) has concluded its 2026 financial year on a high note, reporting strong production results at its Telfer project in Western Australia. For the June quarter, the company produced 79,100 ounces of gold and 3,573 tonnes of copper, bringing total output for the full year to 328,987 ounces of gold and 14,594 tonnes of copper. This performance notably outperformed the company’s original FY26 production guidance of 260,000 to 310,000 ounces, while achieving an all-in sustaining cost (AISC) of $2,179 per ounce, which also tracked better than the initial forecast range of $2,400 to $2,800 per ounce.

The strong operational performance helped boost the company’s financial position. Greatland reported a closing cash balance of $1,289 million as of June 30, 2026, remaining debt-free despite significant capital investments in the period. The company also announced a major upgrade to its reserves, with the total group ore reserves increasing to 5.0 million ounces from 3.9 million previously. Much of this growth originated at Telfer, where ore reserves rose from 0.7 million ounces to 1.8 million ounces—a substantial 150% expansion that secures a multi-year baseload for the site.

"The June quarter capped a very strong year of operations for Greatland in which we beat both production and AISC guidance."

"This balance sheet strength is a robust platform to execute our enviable organic growth profile, through both development of Havieron and continued investment in Telfer extension and growth."

"The investments we make in FY27 will set the foundations for a period of production growth delivered by a higher quality, longer life, gold-copper production centre in the Paterson region."

— Shaun Day, Managing Director

Looking ahead, Greatland has provided FY27 gold production guidance of 260,000 to 300,000 ounces. While this range is slightly lower than the total output for FY26 due to the processing of a higher proportion of lower-grade stockpiles, the company is prioritizing growth investment. The forecast AISC for FY27 is set at $2,900 to $3,330 per ounce, representing a material increase in expected costs as the company accelerates development work. These investments are largely directed toward the multi-decade vision of integrating Telfer and the Havieron project.

Key growth catalysts for the coming year include the commencement of pre-production capital spending at Havieron, expected in the coming weeks following the receipt of secondary approvals. Furthermore, the company continues to advance internal studies at Telfer, with the completion of a study for the West Dome Underground project scheduled for FY27. These developments, supported by a $59 million quarterly investment in growth capital, aim to shift the production profile toward higher-grade underground ore sources. Exploration remains a priority as well, with the team targeting ~215km of drilling in the next financial year to support resource conversion and ongoing reserve growth across the asset base.
