Apollo Hill Drilling Returns Multiple Intercepts Above 2 g/t Au Supporting Resource Upgrade

Robust Drilling Results Bolster Apollo Hill Resource

Saturn Metals Limited (ASX:STN) has delivered a fresh wave of encouraging assay results from its flagship Apollo Hill Gold Project near Leonora, Western Australia. The latest round of 35 Reverse Circulation (RC) and 6 Diamond Drill (DD) holes has revealed multiple thick, higher-grade gold intersections that strengthen the case for upgrading the existing 2.24 million ounce Mineral Resource.

Highlights include standout intercepts such as 16m at 2.46 g/t Au including 5m at 7.14 g/t Au (AHRC1565), 22m at 1.58 g/t Au including 10m at 2.88 g/t Au (AHRC1596), and a remarkable 2m at 21.90 g/t Au (AHRCDD1308). These results are integral to the ongoing resource upgrade process, which Saturn confirms remains on track for completion in the coming weeks.

Resource Upgrade to Underpin Definitive Feasibility Study

Managing Director Ian Bamborough emphasised the consistency and robustness of the drilling outcomes, noting that the upgraded Mineral Resource will form the foundation for the Apollo Hill Definitive Feasibility Study (DFS) and the updated Ore Reserve, both slated for release later this year. This aligns with the company’s recent move to appoint Ausenco for the DFS delivery, reflecting a concerted push to advance Apollo Hill’s development potential Apollo Hill DFS amid new intercepts.

The current Mineral Resource estimate stands at 137.1 million tonnes grading 0.51 g/t Au for 2.24 million ounces of gold, with 82% classified as Measured and Indicated. The new drilling results are expected to enhance resource confidence, quality, and metal content, potentially lifting these metrics further.

Extensive Drilling Program Supports Resource Confidence

The drilling program encompasses 6,820m of RC and 793.41m of diamond drilling, targeting both infill and extensional zones within the Apollo Hill deposit. Notably, the exploration continues beyond the Mineral Resource cut-off date, with assays pending for an additional 46 RC holes and three diamond holes focused on the Titan and Iris Lodes, areas recently highlighted for their high-grade potential.

These efforts build on previous high-grade intercepts such as 15m at 5.53 g/t Au including 7m at 11.23 g/t Au, underscoring the ongoing expansion of mineralisation in the footwall structures high-grade Titan Zone intercepts. The geological continuity and grade tenor observed so far support the company's confidence in the resource upgrade trajectory.

Project Positioned for Large-Scale Heap Leach Operation

Apollo Hill’s mineralisation is hosted within a steeply northeast-dipping contact zone between schist and mafic volcanic-intrusive units. The deposit extends over a 3 km strike length and has been drilled to depths of approximately 500m, with mineralisation amenable to bulk mining and heap leach processing. The company’s previous pre-feasibility study and maiden Ore Reserve estimate underpin a potential large tonnage, low strip open pit operation with simple metallurgy.

With the updated Mineral Resource and Ore Reserve expected imminently, Saturn is poised to refine its development plans and de-risk project economics. The ongoing drilling and forthcoming DFS will be critical in shaping Apollo Hill’s path to production.
