Marillana Agate

Marillana Agate operates within Marillana Station, a vast pastoral holding in the West Pilbara Mineral Field, Pilbara Region, Western Australia. The terrain is characterised by ironstone-rich alluvial plains, spinifex grasslands, and extreme arid conditions with annual rainfall below 300 mm. Surface temperatures routinely exceed 45°C in summer, imposing severe constraints on personnel endurance and equipment thermal management. Water sourcing for any operational activity depends entirely on remote bore infrastructure or trucked supply.

Two operators — Aradon Pty Ltd (Malaga, WA) and Australian Outback Mining — conduct targeted extraction of Crazy Lace Agate from surface and near-surface deposits. The operational model is small-scale and artisanal, supplying the lapidary, collector, and decorative stone B2B markets. Aradon positions itself as a leading Australian quality gem supplier, distributing nationally from WA and Queensland nodes. Rotational field crews operate under FIFO-style rosters given the remoteness of Marillana Station from any permanent township.

• Primary commodity: Crazy Lace Agate (gem-grade, semi-precious)
• Operational model: Small-scale artisanal surface extraction
• Distribution hubs: Malaga (WA) and Mt Hay, Queensland
• Key operators: Aradon Pty Ltd, Australian Outback Mining

Given the artisanal and gemstone-specific nature of this operation, heavy conveyor infrastructure is not deployed at industrial scale. Material handling relies on manual sorting, small mechanical screening, and selective hand-cobbing to preserve gem integrity. The absence of bulk processing circuits reflects the high unit-value, low-tonnage extraction model typical of semi-precious stone operations. Field logistics depend on 4WD access tracks across the station, with no permanent sealed road connection to the extraction zones.

• Manual and semi-mechanical selective extraction
• Hand-cobbing and field-sorting for gem-grade material
• No large-scale conveyor or crushing circuit identified
• 4WD track access; no sealed haul road infrastructure

Operations on Marillana Station are subject to Western Australian Mining Act compliance and pastoral land-use agreements. The low-disturbance footprint of artisanal gemstone extraction reduces tailings generation significantly versus bulk commodity mining; however, proactive site rehabilitation and pit backfilling remain regulatory obligations under DMP/DMIRS frameworks. The value chain is short and traceable — from Pilbara field extraction to direct B2B lapidary and retail supply — supporting provenance-based ESG narratives increasingly demanded by international gem buyers.

• Compliance: WA Mining Act, DMIRS regulatory framework
• Low tailings volume; rehabilitation obligations apply
• Traceable provenance chain from field to B2B buyer
• Pastoral land-use coexistence agreement with station management
