Definitive Feasibility Study Unlocks Havieron's World-Class Potential
The Feasibility Study, released on November 30, 2025, underscores Havieron's exceptional potential, projecting substantial operational capacity and strong financial returns. Key metrics from the study include an impressive mine life projected until June 2046, yielding an average annual production of 221,000 ounces of gold and 8,000 tonnes of copper, with steady-state annual output reaching 266,000 ounces of gold and 9,600 tonnes of copper. The project's Ore Reserve now stands at 38.5 million tonnes, containing 3.3 million ounces of gold and 128,000 tonnes of copper, with a total mining inventory of 51 million tonnes and an annual processing rate of 2.8 million tonnes.
A critical aspect of the FS is the confirmation of Havieron's status as a low-cost operation, with an All-in Sustaining Cost (AISC) of A$1,610 per ounce, reinforcing earlier pre-feasibility indications of globally lowest quartile AISC. This low-cost structure is expected to drive high margins and a fast payback period. Financially, the project is anticipated to deliver A$739 million in pre-tax free cash flow, or A$1.197 billion at spot prices. Pre-production capital expenditure is estimated at A$1.065 billion, which is fully funded through Greatland Gold's existing A$750 million cash balance, cash flow from the recently acquired Telfer mine, and a A$500 million debt facility. Greatland's robust financial position, with a closing cash position of £71.9 million ($146 million) and net assets of £491.5 million ($1 billion), underpins these ambitious development plans.
The journey to this definitive confirmation has been a multi-year effort. Havieron, located approximately 45km east of the former Newcrest Mining (ASX: NCM) (now Newmont) Telfer mine, has been a focal point of exploration and development for Greatland Gold. The project initially gained significant attention for its high-grade gold-copper discovery in the Paterson Province. A crucial strategic move was Greatland Gold's acquisition of the Telfer gold-copper mine in December 2024, which not only provided immediate cash flow but also facilitated the seamless integration of Havieron's operations with Telfer's existing processing plant and infrastructure. This integration minimizes initial capital expenditure, maximizes resource utilization, and streamlines operations, offering significant cost savings and extending the overall mine life of the integrated operations. The successful securing of funding in 2022, ahead of the FS, from major banks and strategic investors like Wyloo Metals, had already signaled strong long-term confidence in the project.
First ore production from Havieron is expected in H2 2026, with initial gold production targeted for H2 2027. Integrated Havieron and Telfer production is slated to commence during FY28, which is projected to lead to a step-change reduction in All-in Sustaining Costs (AISC) and sustained higher volume production. The FS also assesses an expansion of Havieron's mining rate from 2.8 million tonnes per annum (Mtpa) to between 4.0 and 4.5 Mtpa, representing a 43-60% increase in capacity, further boosting its long-term output potential. Initial market reactions, while not explicitly detailed for November 30, 2025, are anticipated to be positive, mirroring previous surges in Greatland Gold's share price following funding successes and positive development news, and contrasting with past dips caused by study delays.
Winners and Losers: A Shifting Landscape in Gold-Copper Mining
The definitive confirmation of the Havieron project as a long-life, low-cost gold-copper operation, coupled with Greatland Gold's (LSE: GGP) full ownership and the acquisition of the Telfer mine, marks a transformative period for the companies involved and the broader mining sector.
Greatland Gold (LSE: GGP) stands as the unequivocal winner. The full consolidation of Havieron and the Telfer mine has transitioned Greatland from primarily an exploration company to a material producer of gold and copper. The Telfer acquisition in December 2024, valued at up to $475 million, provided immediate revenue streams, with Telfer generating $961.3 million in revenue and $337.3 million in net profit after tax for the seven months ending June 30, 2025. This robust cash flow, combined with existing reserves and debt facilities, fully funds Havieron's development, significantly de-risking the project. Greatland's strategy to integrate Telfer as a "hub-and-spoke" processing center for Havieron and future regional discoveries optimizes existing infrastructure, extends Telfer's mine life, and enhances the value of Greatland's extensive exploration portfolio in the Paterson Province. The company's successful dual listing on the ASX in June 2025 further broadened its investor base and capital access, positioning it for enhanced credibility and a potential re-rating in market valuation.
For Newmont (NYSE: NEM), the world's largest gold producer, the divestment of its 70% interest in Havieron and the Telfer mine is part of a broader strategic portfolio optimization following its $26.2 billion acquisition of Newcrest Mining (ASX: NCM) in 2023. While Newmont relinquished direct operational control, it received significant proceeds of up to $475 million, including cash and a 20.4% equity stake in Greatland Gold, making it Greatland's largest shareholder. This allows Newmont to maintain exposure to Havieron's upside potential without the direct capital expenditure and operational responsibilities, aligning with its strategy to streamline operations and focus on "Tier 1" assets. This move contributes to Newmont's goal of generating at least $2 billion from asset sales to reduce debt, and its strong Q3 2025 earnings, driven by record gold prices, provide a solid backdrop for these strategic adjustments.
The broader gold-copper mining sector will also experience ripple effects. The Greatland-Newmont deal is indicative of increased Mergers & Acquisitions (M&A) activity fueled by high gold and copper prices, driven by geopolitical tensions, central bank buying, and demand from AI and EV sectors. Companies with attractive gold-copper assets are likely to see increased interest. Greatland's success in consolidating assets and implementing a regional "hub-and-spoke" model could inspire similar regional consolidation strategies among competitors, unlocking value from smaller, stranded deposits by leveraging existing infrastructure. Furthermore, Havieron's confirmation as a significant, low-cost discovery underscores the value of exploration and discovery, potentially encouraging other junior and mid-tier explorers to intensify efforts in prospective regions like the Paterson Province.
