GE21 Consultoria Mineral

What GE21 Consultoria Mineral does

GE21 Consultoria Mineral is a privately held Brazilian mineral consulting firm headquartered in Belo Horizonte, with branch offices in Salvador (Bahia) and Buenos Aires (Argentina). The firm provides independent technical services across the entire mining project lifecycle, including mineral exploration program design, geological modeling, geostatistical resource estimation, mine planning, geometallurgy, technical-economic studies (Scoping and PEA), due diligence, and international resource/reserve certification under JORC, NI 43-101, S-K 1300, and CBRR codes. The team of 80+ professionals includes 20+ Competent and Qualified Persons (CPs/QPs) affiliated with AIG, AusIMM, and CBRR, with lineage tracing back to Paulo Abib Engenharia, Geoexplore Consultoria e Serviços, and Coffey Mining since the 1980s, giving the firm 45+ years of cumulative experience across 10,000+ projects and 20+ countries.

Underlying technology comprises industry-standard geological and geostatistical modeling packages, GIS-based mineral rights management, airborne and terrestrial geophysical survey capabilities (gamma-spectrometry, magnetometry, electromagnetics, IP/resistivity), computational 3D modeling, and database/QAQC tooling. The firm is part of Grupo GE21, a diversified conglomerate that includes affiliated entities in data analytics (GE21 Analytics), virtual reality (GE21 Realidade Virtual), and geotechnologies (GE21 Geotecnologias), as well as a regional entity in Argentina (GE21 Argentina). A core partnership with Tetra Tech extends delivery capacity for larger multi-disciplinary scopes, and complementary technology alliances (Dassault Systèmes, Revo Geoscience, Redwave, Foraco, GeoScan) supplement specific service lines.

Revenue is generated through project-based professional services contracts with mining producers, exploration firms, project developers, and financial-institution investors, priced by scope, commodity type, geography, and reporting-standard requirements. The go-to-market is sales-led B2B, executed via direct engagement, competitive tenders, professional-network referrals, industry events, and partner-led channels. The client base spans 500+ organizations and includes tier-1 miners such as Vale, Anglo American, BHP, ArcelorMittal, and Kinross, alongside a long tail of mid-cap explorers and critical-minerals developers (Sigma Lithium, Lithium Ionic, Aclara, Bravo Mining, Aura Minerals, Ero Copper). LGPD data-protection compliance and an in-house ethics/anti-corruption manual round out the governance posture.

• AMC Consultants: AMC Consultants is an Australia-based mining consultancy with deep expertise in mine planning, feasibility studies, and due diligence. Directly comparable to GE21 on technical-economic studies, mine planning, and QP-led resource certification work.
• RPMGlobal: RPMGlobal provides mining consulting, software, and advisory services globally, covering resource estimation, mine planning, and due diligence. Comparable to GE21 in offering both technical consulting and software-enabled products for mining project development.
• Optiro (formerly Snowden-Optiro): Optiro specializes in mineral resource estimation, geostatistics, and geological modeling, with strong credentials under JORC. It is a direct peer to GE21's resource estimation and geological modeling practice, particularly for lithium, gold, and base metal projects.
• CSA Global: CSA Global (now part of ERM) provides mineral resource estimation, mine planning, and geological consulting worldwide with strong QP coverage. Competes directly with GE21 on international resource/reserve certification mandates and exploration project evaluation.

Emerging players

• Datamine: Datamine is a mining software and consulting provider that acquired Snowden (resource estimation specialist), creating a hybrid consulting-software competitor. Overlaps with GE21 in resource modeling and increasingly in service-based project delivery.
