Saturn Metals Announces High-Grade Gold Drilling Results Including 1m at 277g/t Au at Apollo Hill
Saturn Metals Limited has announced exceptional high-grade gold assay results from its Apollo Hill Gold Project in Western Australia, including a record 1m intercept grading 277g/t Au. These findings highlight significant untapped northern extensions beyond the existing 2.24Moz Mineral Resource and support ongoing exploration and resource growth.
- Record high-grade intercept of 1m at 277g/t Au at Apollo Hill
- New shallow, high-grade drill results extend mineralisation 200m north of existing resource
- 10,000m drill program underway including diamond drilling to refine geology
- Next Mineral Resource update and Definitive Feasibility Study scheduled for 2026
- Company holds $58.6 million cash as of December 2025, well funded for exploration
Exceptional High-Grade Gold Intercepts at Apollo Hill
Saturn Metals Limited (ASX:STN) has reported outstanding new assay results from extensional drilling at its 100%-owned Apollo Hill Gold Project near Leonora, Western Australia. Among the highlights is a record intercept of 1 metre grading 277 grams per tonne (g/t) gold, the highest grade ever recorded at Apollo Hill. This intercept was part of a broader 4m interval averaging 70.03g/t Au from 54m depth in drill hole AHRC1581, located approximately 200 metres north of the existing 2.24 million ounce Mineral Resource.
Other significant shallow intercepts include 18m at 2.63g/t Au from 5m depth (including 3m at 13.57g/t Au) and 1m at 24.60g/t Au from 93m. These results align with east-west trending mineralised zones interpreted to extend northwards from the current resource, suggesting a new dimension of exploration potential beyond the known deposit boundaries.
Ongoing Drilling and Resource Growth Prospects
The company is advancing a 10,000-metre drilling program to follow up on these promising results. This includes an initial 1,000 metres of diamond drilling aimed at refining geological understanding, followed by further reverse circulation (RC) drilling. These efforts are separate from, and in addition to, recently completed drilling supporting a Mineral Resource upgrade scheduled for release in the second quarter of 2026.
Saturn Metals’ Managing Director, Ian Bamborough, emphasised the significance of the findings, stating that the extensive 2025 drilling and geological work have translated into high-impact exploration success early in 2026. He noted that the growing understanding of the Apollo Hill system has effectively opened a new frontier for discovery and resource growth immediately north of the deposit.
These results will feed into the upcoming Mineral Resource update, the Definitive Feasibility Study (DFS) currently underway, and an updated Ore Reserve expected later in 2026. The DFS is being conducted by Ausenco, a global engineering firm recently appointed by Saturn Metals to advance the Apollo Hill project towards development, as detailed in the company’s recent engagement of Ausenco for the DFS process.
Technical and Operational Context
The Apollo Hill deposit currently hosts a Mineral Resource of 137.1 million tonnes at 0.51g/t Au for 2.24 million ounces of gold, with 82% classified as Measured and Indicated. The Ore Reserve stands at 104.6 million tonnes at 0.47g/t Au for 1.59 million ounces. The mineralisation is associated with quartz veining and carbonate-pyrite alteration within mafic volcanic and intrusive rocks, extending over a strike length of approximately 3 kilometres and to depths of around 500 metres.
Sampling and assay procedures follow industry best practices, including rigorous quality control measures such as standards, blanks, and duplicates. Assays were conducted by Bureau Veritas in Kalgoorlie using fire assay methods. Visible coarse gold was observed in panned RC drill chips from the bonanza-grade intercept, supporting the assay results.
Saturn Metals reported a strong cash position of $58.6 million as of 31 December 2025, providing financial flexibility to continue exploration and project development activities. The company also has pending assay results from 88 drill holes totaling approximately 13,400 metres, which could further inform the resource model and project economics.
Broader Exploration and Development Outlook
In addition to the northern extensions at Apollo Hill, Saturn Metals is advancing exploration at the Titan Zone within the same project area, where recent high-grade results have reinforced resource potential. These developments complement the company’s broader strategy to grow the Apollo Hill resource base and advance the project through feasibility and into production.
Saturn Metals’ recent engagement of Ausenco to lead the DFS underscores the company’s commitment to progressing Apollo Hill as a large-scale, long-life gold operation with heap leach processing. The DFS will incorporate updated Mineral Resource estimates, including the new extensional drilling results, and is targeted for completion in the fourth quarter of 2026.
These developments position Saturn Metals to potentially enhance the value of Apollo Hill through resource growth and project advancement, subject to the outcomes of ongoing drilling, assay results, and feasibility studies.
Bottom Line?
Saturn Metals’ record high-grade intercept and ongoing drilling at Apollo Hill highlight promising northern extensions, but pending assay results and feasibility outcomes will be critical to defining the project’s future resource and development trajectory.
Questions in the middle?
- How will pending assay results from the 88 drill holes influence the upcoming Mineral Resource update?
- What geological factors might control the continuity and true width of the high-grade mineralisation north of Apollo Hill?
- How will the Definitive Feasibility Study integrate these new high-grade intercepts into the project’s development plan and economics?
