Job Title: Senior Geologist, Operations and Quality Control (Barite)

Location: Plateau
Employment Type: Full-time (On-site)

Role Overview

• The Senior Geologist will lead all geological, mineralogical, exploration interface, and quality control activities at the barite gathering and processing facility in Plateau State.
• The role combines field-based geological interpretation with laboratory-driven quality control and operational decision-making.
• The successful candidate will be responsible for identifying, validating, and characterizing barite mineralization in the field, building a coherent geological picture of barite deposition across sourcing areas, and translating this understanding into consistent operational, beneficiation, and commercial outcomes.
• This is a hands-on, site-based role that bridges exploration geology, mining reality, and processing operations.

Key Responsibilities

• Lead all geological, mineralogical, and quality control activities at the barite gathering and processing facility in Plateau State.
• Oversee sample receipt, preparation, testing, validation, and documentation for barite sourced from multiple mining locations.
• Conduct and supervise laboratory tests including specific gravity determination, particle size distribution, moisture content, impurity assessment, and beneficiation test work.
• Establish, implement, and enforce laboratory testing protocols, quality assurance procedures, and documentation standards aligned with API and customer requirements.
• Interpret laboratory and field data to guide operational decisions on ore acceptance, rejection, beneficiation, blending, and stockpile management.
• Coordinate closely with operations, yard management, and logistics teams to ensure material handling and segregation align with quality outcomes.
• Support supplier and miner onboarding by evaluating samples, reviewing geological data, and recommending approval, remediation, or rejection actions.
• Identify recurring quality issues, contamination risks, and recovery losses, and propose practical corrective actions to improve consistency and yield.
• Maintain accurate technical records, batch traceability, and test histories for all incoming and processed materials.
• Prepare regular technical and quality reports for management, highlighting trends, risks, and recommendations that impact procurement, pricing, and off-take decisions.
• Coordinate external laboratory testing where advanced analysis is required and reconcile third-party results with in-house data.
• Conduct field-level geological assessment of barite occurrences, including lithological logging, structural interpretation, and mineral identification at source locations.
• Identify barite mineralization in hard-rock and vein-hosted settings, distinguishing economic barite from gangue minerals and contaminants at mine and stockpile level.
• Build and continuously refine a geological model of barite deposition across sourcing areas, incorporating exploration data, field observations, and laboratory results.
• Support exploration and sourcing strategy by advising on deposit quality, continuity, variability, and upgrade potential across different mining locations.
• Provide geological guidance on selective mining, material segregation, and blending strategies based on deposit characteristics and quality trends.

Required Qualifications and Experience

• PhD in Geology, Economic Geology, Applied Mineralogy, or a closely related discipline is strongly preferred. Candidates with a Master’s degree must demonstrate substantial field and operational experience.
• Minimum of 5 - 8 years of progressive experience spanning exploration geology, economic geology, hard-rock or industrial mineral mining, and operational quality control.
• Demonstrated ability to identify barite mineralization in the field, including vein-hosted, sedimentary, and structurally controlled deposits.
• Strong experience building geological interpretations and deposit understanding that directly inform mining, processing, and quality decisions.
• Practical experience with industrial mineral operations, particularly barite, including beneficiation principles and API-grade requirements.
• Proven track record working in active mining or processing environments in Nigeria or comparable operating contexts.
• Experience establishing or managing site laboratories, supervising technical staff, and enforcing quality control discipline is a strong advantage.

Working Conditions:

• This role is fully site-based in Plateau State and requires daily engagement with yard operations, laboratories, and incoming materials.
• The successful candidate must be comfortable working in a developing industrial environment and willing to be deeply involved in day-to-day operations.

Benefits

• Accommodation.
