Sunshine Metals Boosts Liontown Cash Flow to $179.8m in Updated Study

Sunshine Metals (ASX:SHN) has released an updated Mining Study for its Liontown Gold Project in North Queensland, reporting a 10% increase in net operating cash flow to $179.8 million. The study, which supersedes the February 2026 iteration, projects gross revenue of $497.5 million over a 66-month life-of-mine, driven by the production of approximately 80,000 ounces of gold and 952,000 ounces of silver.

Economic metrics have improved across the board, with all-in sustaining costs declining by 6% to $2,579 per ounce of gold. The company’s maximum cash drawdown remains minimal at $5.5 million, a result of the project’s rapid payback period of roughly four months. As reported by Mining.com.au, the study assumes gold and silver prices of $6,500 and $100 per ounce, respectively, underpinning the enhanced financial outlook.

Production strategy relies on rapid underground extraction

The operational plan involves a three-stage open pit phase lasting 27 months, followed by 42 months of underground mining. The underground phase targets the high-grade Au Panel, which contains 63,800 ounces of gold and 96,700 ounces of silver. Mining will utilize longhole stoping with cemented rockfill to ensure stability and efficiency.

Metallurgical testing confirms rapid leach kinetics, achieving over 90% gold recovery within two hours. Combined gravity and leach extraction rates range between 86% and 96% depending on the ore domain. The project incorporates the July 2026 mineral resource estimate, with 84% of the production target derived from measured and indicated resources.

Capital requirements and timeline remain modest

Life-of-mine capital is estimated at $56 million, supporting the company’s goal of becoming a self-funded explorer. Managing Director Damien Keys noted that the acquisition of the Mt Moss mill and rapid development progress underpin the timeline for first gold production in mid-2027. The mill is currently undergoing refurbishment to process the ore.

Sunshine Metals held $20.6 million in cash as of June 30, 2026, providing a buffer for the upcoming development phase. The company plans to release a base metal Mining Study in October 2026, targeting the remaining 86% of its broader 7.3-million-tonne resource. Early contractor engagement is underway to maintain the mid-2027 commencement schedule.

Approvals and resource base support expansion

Mining and environmental approvals are well advanced, facilitating the transition to a sustainable gold and base metals producer. The resource base includes 1 million tonnes at 3.8g/t gold for 122,600 ounces and 29.9g/t silver for 975,000 ounces. This robust resource position allows for the multi-stage operational approach outlined in the updated study.
