Mt Minnie

Project Logistics & B2B Overview

Geographic Location and Topography

Mt Minnie Granite is situated within the Ashburton M.F. pastoral district, Pilbara region, Western Australia — a semi-arid plateau characterised by exposed Precambrian granite outcrops and lateritic red-dirt overburden. Elevation gradients are moderate but surface conditions generate fine particulate dust (PM10/PM2.5) at high volumes during dry-season operations. Vendors supplying filtration systems, dust suppression units, and abrasion-resistant wear components face consistent, high-frequency demand driven by the region's extreme aridity and abrasive silica-rich geology.

B2B Lifecycle and Operational Status

The site holds Operating status, indicating active extraction and ongoing procurement cycles. Given the remoteness of the Ashburton corridor, operational continuity depends on FIFO/DIDO rotational rosters — typically 2:1 or 14:7 swing patterns sourced from Carnarvon or Geraldton. Camp and accommodation logistics, portable ablution units, catering supply chains, and satellite communications infrastructure represent critical B2B service verticals. No confirmed operator entity is publicly registered; vendor engagement should target the pastoral lease holder or WA DMP tenement records directly.

Engineering and Extraction Infrastructure

As a granite quarry classified under construction materials, the primary circuit involves drill-and-blast fragmentation followed by jaw crushing (primary) and cone crushing (secondary/tertiary) to produce road base, armour rock, and aggregate spec products. Abrasion indices for Pilbara granite (BWi typically 18–24 kWh/t) impose high wear rates on liners, mantles, and screen media. Flotation circuits are not applicable at this commodity tier; however, wash-water management and fines classification via hydrocyclone or wet screening may be required to meet MRWA aggregate specifications.

ESG, Value Chain and Sustainability

Operations within the Ashburton district intersect with registered Aboriginal Heritage sites under the WA Aboriginal Heritage Act 1972 (as amended 2021), requiring Section 18 consent protocols and active engagement with relevant Prescribed Body Corporates — likely Yugunga-Nya or Murchison region groups. B2B contractors are increasingly required to demonstrate Indigenous procurement commitments aligned with the WA Indigenous Procurement Policy. Environmental obligations include dust suppression plans, cleared vegetation offsets, and rehabilitation bonds lodged with DMIRS as conditions of the Mining Proposal approval.
