Saturn Metals’ second gold centre: drilling strategy and mine planning lens
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Saturn Metals has begun a 10,000m reverse circulation drilling campaign along the 26.5km Aquarius Gold Trend in Western Australia’s Leonora district, 30km from its flagship Apollo Hill project, to establish a second gold centre. Drilling is targeting extensions of historical gold mineralisation and untested structural positions along the trend, using RC to rapidly sample to depth in the weathered and fresh rock profile. Success would materially expand the Apollo Hill regional resource base and influence future mine planning and processing hub configuration in the district.
Technical Brief
- Initial campaign is explicitly framed as “major exploration”, signalling pre-resource, pre-feasibility project stage.
- Reverse circulation drilling is suited to Leonora’s deeply weathered Archaean profiles, enabling high‑throughput chip sampling.
- RC drilling allows relatively low-cost penetration into fresh rock, de-risking structural interpretations before diamond coring.
- Historical gold mineralisation along Aquarius provides existing collar and assay control for step-out and infill drill design.
- Structural targets along the trend are likely controlled by shear zones typical of Eastern Goldfields greenstone belts.
- For similar Western Australian mining projects, such satellite trends often evolve into supplementary ore feed for central mills.
Our Take
Our database shows multiple 2026 updates on Apollo Hill’s resource growth and step‑out drilling, so targeting a second gold centre only 30km away on the Aquarius Gold Trend suggests Saturn Metals is already thinking in terms of a multi‑centre hub rather than a single‑pit operation in the Leonora district.
With Ausenco already engaged on a standalone gold scoping study at Apollo Hill, any future definition of resources along the 26.5km Aquarius Gold Trend could be engineered either as satellite feed or a separate processing centre, giving Saturn optionality on capex staging in Western Australia.
