What Primero Group does

Primero Group is a multidisciplinary engineering, procurement, and construction (EPC) contractor specializing in project delivery for the mining, energy, and resources sectors. Founded in 2011 and headquartered in Osborne Park, Western Australia, the company delivers integrated solutions across the full asset lifecycle — from feasibility studies and front-end engineering design through construction, steady-state operations, and ongoing maintenance. It serves enterprise clients in gold mining, iron ore, critical minerals (lithium, vanadium, rare earths), energy infrastructure, and hydrogen/renewables, with named customers including Rio Tinto, Fortescue, Northern Star Resources, Core Lithium, Piedmont Lithium, Covalent Lithium, Australian Vanadium, Wärtsilä, APA Group, South32, Hazer Group, Strandline Resources, and Tietto Minerals.

The company's portfolio combines standard EPC service lines (Studies & Engineering, EPC, Construction, Operations, Maintenance) with two proprietary assets. ALi® is a fully-atmospheric leach process for refining spodumene concentrate into battery-grade lithium carbonate, claiming 99.8% purity and 92.5% recovery without sulphuric acid; it was selected by PMET Resources in June 2026 over six other commercial refining methods. Checkmate is a paperless ITR (Integration to Ready) commissioning system running on wireless tough-books for multi-discipline implementation. Capability statements cover Overarching, Energy, Critical Minerals, Studies & Engineering, Operations & Maintenance, and Defence verticals, and operations extend across Australia, the United States (Houston), Canada (Toronto, Montreal), and Africa (Côte d'Ivoire).

Commercial models are predominantly professional-services and managed-services. Revenue is generated through fixed-price and incentivized target-cost EPC contracts, study fees, and long-term operations & maintenance agreements including Build-Own-Operate (BOO) arrangements, with go-to-market via direct enterprise tender processes and relationship-based business development. Following a February 2021 takeover by NRW Holdings (ASX: NWH), Primero delisted from the ASX and now operates as a wholly-owned subsidiary spearheading NRW's Minerals, Energy and Technologies (MET) division.

Core offering

Primero Group is a multidisciplinary engineering, procurement, and construction (EPC) company that delivers fully integrated solutions for the mining, energy, and resource sectors. Its offerings span the entire project lifecycle — from feasibility studies and early-stage design, through EPC and construction, to operations, maintenance, and sustaining capital services — augmented by the proprietary ALi® atmospheric leach technology for lithium refining.

Product overview

Primero Group is a multidisciplinary engineering, procurement, and construction (EPC) company that is a wholly-owned subsidiary of NRW Holdings (ASX: NWH). It does not offer a unified software product in the traditional sense; rather, its offerings consist of a portfolio of professional engineering services and proprietary processes. The core service offerings are Studies & Engineering, EPC, Construction, Operations, and Maintenance, delivered across five project portfolios: Critical Minerals, Gold, Iron Ore, Renewables, and Energy. The primary proprietary technology is the ALi® atmospheric leach process for battery-grade lithium carbonate production from spodumene. A secondary proprietary tool is Checkmate, a paperless ITR commissioning system. Projects span lithium, gold, iron ore, hydrogen, vanadium, and copper, with clients including Rio Tinto, Fortescue, Pilbara Minerals, Core Lithium, Piedmont Lithium, and Nemaska Lithium.

Broad incumbents

• Hatch Ltd: Global engineering and project delivery firm with strong mining, metals, and energy practice. Comparable to Primero in process engineering and EPC delivery for mining clients, though broader in scope and global in footprint.
• Downer EDI: Large ASX-listed contractor with services and infrastructure capability including mining, rail, utilities, and energy. Competes with Primero in resources and energy projects, but operates at a broader scale across multiple sectors.
• Worley Limited: ASX-listed global energy and resources engineering firm (now owning DRA Global's minerals business). Overlaps with Primero on critical minerals and energy EPC services but competes from a much larger, broad-based energy transition positioning.
• Fluor Corporation: Global Fortune 500 EPC firm with major mining, critical minerals, and energy practice. Competes with Primero on large lithium and base-metals projects globally, including in Australia and North America, and brings greater scale and balance-sheet depth.

Direct peers

• DRA Global: Global mining and minerals processing EPCM specialist with deep roots in South Africa and Australia. Highly comparable to Primero in that both deliver studies, engineering, and EPC services for base metals, precious metals, and critical minerals projects on a multi-client basis.
• Sedgman: Mineral processing EPC business (a subsidiary of Stantec) focused on coal, iron ore, copper, and battery materials. Direct competitor for process plant EPC contracts in the Australian mining sector with similar end-to-end engineering-to-construction capability.
• Monadelphous Group: ASX-listed Australian engineering and infrastructure services contractor with significant exposure to iron ore, lithium, and energy projects for tier-1 miners. Competes with Primero for sustaining capital and brownfield construction work in Western Australia.
• Lycopodium: Australian-headquartered process engineering and EPC contractor specialising in minerals processing and critical minerals (lithium, gold, copper, nickel). Most directly comparable to Primero given shared focus on FEED/DFS-to-EPC delivery for mining clients in Australia and internationally.
• MACA Limited: Australian mining contractor (now part of Thiess/Pembridge) providing mining services, civil and infrastructure construction, and crushing services to tier-1 iron ore and gold miners in WA. Overlaps with Primero on iron ore construction work and process infrastructure.
• GR Engineering Services: ASX-listed Australian mineral processing EPC contractor with strong gold, lithium, and base metals exposure. Closely comparable to Primero in scope (studies, design, construction), customer base, and delivery model for resource-sector projects.
