Apollo Hill Drilling Yields 38m at 1.24g/t Au, Supporting 2.03Moz Resource

Apollo Hill Drilling Delivers Strong Continuity and Growth Signals

Saturn Metals Limited (ASX: STN) has released a compelling update on its flagship Apollo Hill Gold Project in Western Australia, reporting significant assay results from 38 reverse circulation drill holes totaling over 8,200 meters. These results not only confirm the robustness and continuity of the recently upgraded 2.03 million ounce mineral resource but also reveal promising extensional zones that could materially expand the resource base.

The extensional drilling highlights include intercepts such as 38 meters at 1.24 grams per tonne (g/t) gold from 331 meters depth, including a higher-grade 12 meters at 3.39 g/t Au, and 32 meters at 1.12 g/t Au from 136 meters, featuring 8 meters at 3.44 g/t Au. In-fill drilling aimed at upgrading resource classification also delivered strong results, with standout intercepts like 29 meters at 1.48 g/t Au including 5 meters at 6.96 g/t Au, and 19 meters at 1.73 g/t Au with 9 meters at 3.40 g/t Au.

Supporting an Accelerated Development Strategy

These drilling outcomes reinforce Saturn Metals’ strategy to advance Apollo Hill as a large tonnage, heap leach gold operation. Managing Director Ian Bamborough emphasized the significance of the results, noting that the in-fill drilling is effectively consolidating the deposit while extensional results point to substantial upside potential. The company plans a second resource upgrade in the second half of 2025, which will feed into a Pre-Feasibility Study targeted for completion later this year.

Located near Leonora in the prolific Western Australian goldfields, Apollo Hill benefits from strong infrastructure and a geological setting conducive to open pit mining. The deposit’s mineralisation extends over a 2.4-kilometer strike length and has been tested to depths of approximately 350 meters, with the current resource estimate based on 118.7 million tonnes at 0.53 g/t Au.

Implications for Saturn Metals and Investors

The continuity and grade consistency demonstrated by the recent drilling underpin confidence in the deposit’s economic potential and support the company’s aggressive exploration and development timetable. The high-grade zones within broader mineralised intervals are particularly encouraging for heap leach processing economics, which rely on consistent, recoverable gold grades.

Saturn Metals also holds an option to earn an 85% interest in the West Wyalong Project in New South Wales, a high-grade vein gold opportunity, but Apollo Hill remains the company’s core focus given its scale and development readiness.

As Saturn advances its drilling program, investors will be keenly watching for the upcoming resource upgrade and Pre-Feasibility Study results, which will provide greater clarity on project economics and potential production timelines.
