Green Head

The Green Head operation is situated within Western Australia's Mid-West region, a coastal-to-inland transitional zone characterised by low-relief aeolian limestone plains and calcareous sand deposits. The flat to gently undulating terrain minimises overburden stripping ratios, enabling efficient mass earthworks with reduced bench complexity. Proximity to coastal dune systems influences deposit continuity and moisture content variability, which are critical parameters for downstream product grading and stockpile management.

Green Head is classified as an operating asset under Yarra Sand's regional portfolio, targeting limestone and limesand extraction for construction, agricultural lime, and civil supply markets. Key B2B operational considerations include:

• DIDO roster model typical for regional WA quarry operations
• Direct operator contact structure (Rayner family management — owner-operator model)
• Supply continuity dependent on seasonal haul road conditions in the Mid-West corridor
• No confirmed third-party camp or accommodation infrastructure on-site

Limesand and limestone operations at this scale typically deploy:

• Primary jaw or impact crushing circuits for limestone sizing
• Screening and classification decks for limesand grading (fine aggregate fractions)
• Dust suppression systems — critical given the calcareous fines generation profile
• No flotation circuit applicable — product beneficiation limited to mechanical sizing
• Load-and-haul fleet scaled to low-to-medium annual tonnage output

Operating within the Mid-West WA jurisdiction, Green Head is subject to:

• Aboriginal Heritage Act (WA) compliance — mandatory due diligence for any ground disturbance expansion
• Engagement obligations with local Yamatji Nation representative bodies for heritage clearance
• Environmental licensing under DWER for extractive industry operations
• Rehabilitation bond requirements tied to progressive quarry floor restoration
• Preference for local and Indigenous procurement aligned with WA Government supplier diversity frameworks
