Principal Geologist, Structural Mapping

Job Purpose
 

The Principal Geologist, Structural Mapping is responsible for providing corporate-level expertise in structural geology across all BMNM assets. The role ensures that structural controls on mineralization are consistently interpreted, mapped, and integrated into geological models, resource estimates, and mine designs.
This position strengthens internal capability in structural interpretation, which is currently fragmented or consultant-driven, and ensures that structural understanding directly supports Mineral Resource confidence, mine planning assumptions, and operational execution in both open-pit and underground environments.
 

Key Accountabilities
 

QA/QC Framework & Standards
•    Define and maintain BMNM-wide QA/QC standards for drilling, sampling, assay, and data handling.
•    Ensure consistent application of QA/QC protocols across all sites and projects.
•    Establish acceptance criteria, escalation thresholds, and corrective action processes.
 

Structural Interpretation & Modeling
•    Lead structural interpretation at deposit and district scale, integrating surface mapping, drill core logging, and geophysical data.
•    Define structural frameworks controlling mineralization, continuity, and ore shoot geometry.
•    Ensure structural interpretations are consistently incorporated into geological and resource models.
 

Support to Resource Evaluation & Classification
•    Provide structural input into Mineral Resource interpretation, domaining, and classification.
•    Support continuity assessments and uncertainty analysis related to faulting, folding, and deformation.
•    Work closely with geostatisticians and modelers to ensure structural constraints are correctly applied.
 

Operational & Underground Support
•    Support open-pit and underground operations by providing structural guidance for:
o    Stope and pit wall design assumptions
o    Orebody continuity and dilution risk
o    Geotechnical and mining interfaces (in collaboration with geotechnical teams)
•    Assist with structural mapping programs in active pits and underground development.
 

Governance & Standardization
•    Define standards and best practices for structural logging, mapping, and interpretation across BMNM.
•    Review and peer-assess structural components of internal and consultant-generated models.
•    Ensure structural assumptions are documented, traceable, and defensible.
 

Capability Building
•    Mentor site geologists in structural logging, interpretation, and model integration.
•    Develop guidelines and training material to improve structural competency across operations.
•    Reduce reliance on external structural consultants by building sustainable internal expertise.
 

Minimum Qualifications, Experience and Competencies
 

Minimum Qualifications: 
    Bachelor’s degree in Geology or Earth Sciences.
    Postgraduate qualifications in Structural Geology or Economic Geology are highly desirable.
    Recognized as (or eligible to be) Competent Person under JORC/CRIRSCO.
 

Minimum Experience:
    10+ years’ experience in structural geology within gold or base metal systems.
    Strong experience integrating structural geology into resource models and mine planning.
    Exposure to both open-pit and underground mining environments.
    Experience reviewing or delivering consultant-led structural interpretations.
    Experience supporting internal or external technical audits.
Ma’aden High Performance Competencies:

Skills:
•    Advanced structural interpretation and 3D thinking.
•    Strong understanding of ore controls and structural continuity.
•    Ability to communicate complex structural concepts clearly to non-specialists.
•    High level of technical rigor and governance mindset.
