What is contract mineralogy?

Contract mineralogy is a specialized service in which laboratories or consulting firms analyze and characterize mineral samples for clients, typically in the mining, environmental, or materials industries. The goal is to provide detailed information about the mineral composition, structure, and distribution within ore samples to aid in exploration, processing, and environmental management. This work often involves techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and automated mineralogy systems. By outsourcing mineralogical analyses, companies can access expert knowledge and advanced technology without maintaining their own in-house labs.

What are the key skills and qualifications needed to thrive as a contract mineralogist, and why are they important?

To thrive as a Contract Mineralogist, you need a strong background in geology, mineral identification, and analytical techniques, typically supported by a relevant degree in geology or earth sciences. Familiarity with laboratory equipment such as scanning electron microscopes (SEM), X-ray diffraction (XRD), and mineral analysis software is essential. Attention to detail, effective communication, and problem-solving skills help mineralogists excel in interpreting data and conveying findings to clients. These competencies ensure accurate mineral characterization and valuable insights for mining, environmental, and industrial projects.

How does a contract mineralogist typically collaborate with geologists and mining engineers on client projects?

Contract Mineralogists often work closely with geologists and mining engineers to analyze mineral samples and interpret ore characteristics for exploration or production projects. They provide detailed mineralogical reports that inform resource estimation, process optimization, and environmental management. Effective communication and timely data sharing are key, as their findings directly impact project decisions and operational strategies. Regular team meetings and shared digital platforms are commonly used to facilitate collaboration and ensure alignment with client objectives.

What is the difference between Contract Mineralogy vs Mineral Processing Technician?

AspectContract MineralogyMineral Processing Technician
CredentialsGeology or mineralogy degree, certifications in mineral analysisTechnical diploma or associate degree, certifications in processing equipment
Work EnvironmentLaboratories, field sites, consulting projectsProcessing plants, mining operations, industrial facilities
Industry UsageMining companies, consulting firms, research institutionsMining companies, processing plants, mineral extraction facilities

Contract Mineralogy involves analyzing mineral samples, providing expert assessments, and consulting on mineral properties. In contrast, Mineral Processing Technicians focus on operating and maintaining processing equipment to extract minerals. Both roles require technical knowledge but differ in focus: analysis versus processing operations.

Job description

About Mariana Minerals
Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We're reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
Mariana is hiring a Global Sourcing Manager to own procurement for our new projects and pre-operational sites. This is a senior, self-directed role requiring deep technical and commercial experience in industrial procurement.
In this role, you will ensure sites have the supply agreements, vendor relationships, and procurement coverage they need before they go live. You will work across engineering, operations, and commercial functions to translate project needs into executed contracts, and identify sourcing opportunities across the portfolio. This role covers operating supplies, consumables, and non-construction capital spend. Construction and fixed equipment procurement are owned by the Capital Projects team.
What You'll Do
  1. Work directly with engineering and technical teams to define procurement requirements for pre-operational sites; translate technical specifications into sourcing scope
  1. Own end-to-end pre-operational procurement: qualify vendors per established policy frameworks, run RFQ and competitive bid processes, negotiate pricing and contract terms, execute purchases, manage first deliveries
  1. Procure operating supplies and consumables (including reagents and spare parts) and non-construction capital spend (including mobile equipment)
  1. Ensure all contracts are reviewed for policy compliance and enterprise-level alignment prior to execution; flag clauses with broader implications
  1. Own vendor relationships through the pre-operational phase; ensure clean handoff to on-site procurement as sites become operational
  1. Support on-site procurement on complex purchases, high-value negotiations, and new project scope at existing operational sites
  1. Lead cross-site consolidation sourcing events to identify and capture volume-based savings opportunities
  1. Contribute quote data and supplier information to the organization's pricing and market intelligence database
  1. Coordinate across site and project teams to ensure continuity of supply through startup and into operations

Desired Qualifications
  1. Bachelor's degree in engineering, materials science, chemistry, or a related technical field required. Candidates without a degree who can demonstrate equivalent technical depth through experience will be considered.
  1. 8-12+ years of experience in procurement, project procurement, or capital purchasing in mining, industrials, chemicals, or a related sector
  1. Proven track record of owning pre-operational or greenfield site procurement from spec to first delivery
  1. Strong technical background with the ability to read specifications, understand process requirements, and engage credibly with engineering teams
  1. Excellent negotiation skills with a track record of securing favorable terms under time pressure and without a large team behind you
  1. Highly organized with the ability to manage multiple concurrent procurement workstreams across different projects and sites
  1. Comfortable operating with ambiguity and limited structure; takes ownership and figures it out
  1. Proficient with software tools for project tracking, workstream management, and reporting
Our culture is built on three principles:
Extreme Ownership - We take full responsibility for outcomes, relentlessly driving toward solutions.
Engineer Out Requirements, then Automate - We simplify, optimize, and then automate for scale.
Share Your Legos - We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.
Join us as we build the future of responsible mineral sourcing and supply.
