RGS Environmental Consultants

What RGS Environmental Consultants does

RGS Environmental Consultants is an owner-operated, Brisbane-headquartered environmental consulting firm that delivers geochemistry and hydrogeochemical services to the mining and mineral processing industry across the project lifecycle — from exploration through to rehabilitation and closure. Its portfolio spans six integrated service lines: Mine Water Studies, Geochemistry and Contaminated Land, Mine Waste Management, Soil Science and Rehabilitation, Predictive Numerical Modelling, and Mine Closure. The firm operates its own state-of-the-art geochemistry and physical testing laboratory in Brisbane, equipped with kinetic and static leach testing capability, water quality testing, particle size distribution, and a fully licensed portable handheld XRF spectrometer for metals and metalloid analysis.

Technically, RGS combines its laboratory with an integrated modelling stack that includes GoldSim (with the Contaminant Transport module) for final void/pit lake water balance and water quality simulation, Geochemist's Workbench and PHREEQC for reactive transport and hydrogeochemical modelling, the Deswik CAD/Enviro/LHS suite for mine planning and waste facility design, SEEP/W for unsaturated-zone / cover-system modelling, and Python for numerical analysis. This combination of wet-lab characterization and physics-based simulation underpins the firm's ability to deliver pit lake assessments, AMD management plans, TSF rehabilitation designs, PRCPs, and regulatory submissions for clients such as Whitehaven Coal, Glencore (Mount Isa Mines, Oaky Creek), ENGIE (Hazelwood), Evolution Mining, Lane Xang Minerals, Hume Coal, Multicom Resources, BMA, MMG, and Victorian/NSW government agencies.

RGS makes money through project-based, quote-priced professional services engagements with enterprise mining operators and government clients, supplemented by recurring laboratory testing revenue from its Brisbane facility. With approximately 17 team members, the firm has executed over 600 projects across Australia, China, SE Asia, Micronesia, the South Pacific, South America, and Africa. Client acquisition is referral- and reputation-driven through direct engagement with mining companies and via partnering with other specialist consulting firms on larger multi-disciplinary mandates. The company is bootstrapped, privately held, and has been operating continuously for 19 years.

Core offering

RGS Environmental Consultants provides environmental geochemistry and hydrogeochemical consulting services to the mining and mineral processing industry, covering mine waste characterisation, mine water management (including pit lake and acid/metalliferous drainage assessments), soil science and rehabilitation, predictive numerical modelling, and mine closure planning from exploration through rehabilitation and closure. The firm operates its own state-of-the-art geochemistry and physical testing laboratory in Brisbane and delivers services through direct, project-based consulting engagements on a quote-based pricing model.

Product overview

RGS Environmental Consultants offers a portfolio of environmental consulting services for the mining industry, spanning six core service areas: Mine Water Studies, Geochemistry and Contaminated Land, Mine Waste Management, Soil Science and Rehabilitation, Predictive Numerical Modelling, and Mine Closure. The company operates its own geochemistry and physical testing laboratory in Brisbane. These services are provided as consulting engagements rather than standalone software products, delivering technical expertise from exploration through to rehabilitation and closure for mining projects.

Broad incumbents

• AECOM: Global infrastructure consultancy with a substantial mining environmental practice covering mine water, closure and geochemistry. Competes for large mining and government engagements in Australia and internationally.
• Tetra Tech: Global consulting and engineering firm with a leading mining and water practice, including mine waste characterisation and water quality modelling. Overlaps with RGS's geochemistry, modelling and closure offerings at the larger end of the market.
• WSP: Global professional services firm with a major mining environment and earth practice, including the legacy Golder Associates business. Already a documented RGS collaborator (re-injection compatibility study) and direct competitor on mine water and environmental studies.
• Stantec: Global engineering, environmental and consulting firm with a mining environmental practice spanning water, closure and geochemistry. Competes with RGS for mining clients in Australia and internationally.
• ERM (Environmental Resources Management): Global environmental, health, safety and sustainability consultancy with a substantial mining sector practice. Competes with RGS on environmental impact assessment, mine closure and ESG/sustainability mandates for major miners.

Direct peers

• GHD: Australia-headquartered engineering, environmental and advisory firm with significant mining sector exposure across geochemistry, water and closure. Competes with RGS for Australian mining clients and on government rehabilitation studies in the same geographies.
• Advisian (Worley): Worley-owned global consulting arm with deep mining and resources practice covering environment, water and closure. Direct competitor on mining environmental and closure scopes and a likely counterparty in consortium bids.
• SLR Consulting: Global environmental and advisory consultancy with a strong mining environmental practice covering geochemistry, water management and mine closure. Direct competitor for the same mining-major clients on geochemical characterisation, water balance and closure studies.
• ATC Williams: Australian specialist consulting firm focused on mine water, tailings storage facilities, and geotechnical engineering. Closest direct peer to RGS given overlapping service lines in mine water management, tailings and closure, and shared Australia-headquartered footprint.
• Klohn Crippen Berger: Engineering consultancy specialising in mine waste, tailings, water and geotechnical services globally. Closely comparable to RGS in technical scope (tailings, water balance, geochemistry integration) and target mining clients.
