DBCEC Sand and Gravel

Project Logistics & B2B Overview

Geographic Location and Topography

The operation is situated on Lot 751 Donnybrook-Boyup Brook Road, Beerlerup, WA 6239, within the South West Mining Field. The terrain is characterised by undulating lateritic profiles typical of the Blackwood River catchment. Proximity to riparian corridors and native vegetation buffers mandates rigorous surface hydrological management, including diversion bunding and sediment control basins to prevent fines migration into adjacent protected ecosystems under DWER regulatory oversight.

B2B Lifecycle and Operational Dynamics

Currently operating as a dual-entity venture — Smith Sands Pty Ltd (landholder) and DBCEC (WA) Pty Ltd (civil earthmoving operator) — the site supplies sand and gravel directly to regional construction markets. The acute operational risk lies in mobile plant downtime: the nearest heavy mechanical workshops are concentrated in Bunbury (~50 km north), making on-site preventive maintenance contracts and local workshop partnerships a critical B2B procurement priority to sustain extraction continuity.

Extraction Engineering and Infrastructure

The quarry employs a primary crushing and screening circuit configured for alluvial and semi-consolidated sand-gravel deposits. No flotation plant is applicable at this construction-materials scale; however, wet classification and hydrocyclone separation are the dominant physico-chemical processes to achieve graded product specifications (AS 2758.1 compliance). Infrastructure includes wheeled loaders, hydraulic excavators, and mobile screening units. The absence of deep-shaft infrastructure reduces capital intensity but elevates dependency on reliable mobile fleet availability.

ESG, Value Chain and Sustainability

As a construction materials quarry, tailings facilities in the conventional hard-rock sense are not applicable; however, fines pond management and progressive rehabilitation of extracted cells are mandatory under WA Mining Act conditions. ESG obligations include native vegetation offset requirements, dust suppression protocols, and post-extraction landform recontouring. Proactive rehabilitation scheduling — concurrent with active extraction panels — is the benchmark practice expected by the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) for licence renewal and community licence to operate.
