Crooked Brook

Project Logistics & B2B Overview

Geographic Location and Topography

The Panizza Crooked Brook site is situated within the South West Land Division of Western Australia, in proximity to the Crooked Brook locality — a zone characterised by undulating lateritic terrain and dense native jarrah-marri forest. The region falls within a Phytophthora cinnamomi (Dieback) high-risk corridor, mandating strict biosecurity hygiene protocols for all plant, equipment, and personnel entering the operational footprint. Soil profiles are predominantly gravelly laterite over weathered granite, presenting moderate geotechnical complexity for surface extraction works.

B2B Lifecycle and Operations

Currently classified as Operating under the South West Mining Field, the Panizza Crooked Brook quarry is managed by J & P Deconstruction Pty Ltd, a subsidiary of the J&P Group headquartered in Picton WA. The operation supplies construction-grade aggregate and raw materials to regional civil and infrastructure markets. Given the site's rural-peri-urban positioning, workforce mobilisation follows a DIDO (Drive-In Drive-Out) roster model, leveraging the Bunbury–Picton labour catchment. No permanent camp infrastructure is recorded for this scale of operation.

Engineering and Extraction Infrastructure

As a construction materials quarry, the Panizza Crooked Brook operation centres on drill-and-blast or rip-and-load surface extraction, followed by primary crushing circuits to produce graded aggregate fractions. Key engineering considerations include:

• Primary jaw or impact crusher circuits for coarse aggregate reduction
• Screening decks for multi-fraction product classification (road base, drainage aggregate, fill)
• Dust suppression systems compliant with DER South West regional air quality standards
• Haul road design engineered for heavy articulated truck (HAT) payloads
• Stormwater and sediment control bunding — critical given Crooked Brook catchment sensitivity

ESG, Value Chain and Sustainability

Operating within a biodiversity-sensitive South West corridor, the Panizza Crooked Brook site is subject to progressive rehabilitation obligations under DMIRS tenure conditions. ESG priorities for this operation include:

• Dieback hygiene management plans — mandatory equipment wash-down stations at site entry/exit
• Progressive land rehabilitation and native revegetation post-extraction
• Minimisation of clearing footprint aligned with EPA South West biodiversity offsets policy
• Potential integration of solar-assisted site power for ancillary plant and lighting loads
• Supply chain localisation — short-haul delivery reducing transport-scope emissions for regional civil projects
