About Jerritt Canyon
The Jerritt Canyon deposit was discovered in 1972, and the first gold production from the property occurred in 1981. The Jerritt Canyon property contains 30,821 hectares of mining claims located in the mining-friendly state of Nevada. First Majestic acquired the Jerritt Canyon Gold Mine from Sprott Mining Inc. on April 30, 2021. In May 2023, operations were suspended to prioritize exploration and technical studies. Jerritt Canyon is now entering a new phase of evaluation and planning, requiring substantial technical support to advance the work necessary for a potential future restart of operations.
The Opportunity
The Logging Geologist is responsible for overseeing and coordinating all geological logging activities associated with exploration and resource drilling programs at gold mining operations. This role provides technical leadership to the logging team and ensures that RC, Sonic, and diamond core drillholes are logged accurately, consistently, and in accordance with established geological, quality assurance, and data management standards.
The Logging Geologist works closely with drilling geologists, modeling geologists, core shed personnel, and drilling contractors to ensure high-quality geological data is collected, validated, and delivered in a timely manner for geological interpretation, resource modeling, and mine planning. The position also plays a key role in maintaining consistency across logging practices and ensuring that geological observations are captured to the required standards.
Responsibilities
- Lead, supervise, and coordinate day-to-day geological logging activities for RC, Sonic, and diamond core drillholes.
- Oversee and provide technical guidance to geological loggers to ensure consistent, accurate, and high-quality logging practices.
- Log and/or review geological data including lithology, alteration, mineralization, veining, structure, oxidation, weathering, and other relevant geological characteristics.
- Ensure RC, Sonic, and core samples are logged in accordance with established geological logging procedures and project standards.
- Validate geological logging completed by the logging team and identify, investigate, and resolve inconsistencies or data-quality issues.
- Maintain consistency and continuity in geological logging across multiple drill programs, geologists, and drilling methods.
- Work closely with core shed personnel to ensure the proper handling, organization, photography, sampling, storage, and geological documentation of drill core and samples.
- Collaborate with drilling geologists and drilling contractors to monitor drilling progress, identify geological or operational issues, and ensure logging requirements are being met.
- Work closely with modeling and resource geologists to ensure logging data meets the requirements for geological interpretation, domaining, and resource modeling.
- Review geological data and provide feedback to the logging team to improve data quality, consistency, and efficiency.
- Assist with the development, implementation, and continual improvement of geological logging procedures, standards, and workflows.
- Ensure logging data is entered accurately into the appropriate geological databases and systems.
- Perform routine data validation and QA/QC checks on geological logging information.
- Identify geological trends, discrepancies, and areas requiring additional investigation or follow-up.
- Participate in the review and interpretation of geological data to support exploration and resource development programs.
- Attend and actively participate in logging, drilling, and geological modeling meetings, providing updates on logging progress, data quality, geological observations, and issues requiring resolution.
- Coordinate communication between logging personnel, core shed staff, drilling teams, drilling geologists, and modeling geologists.
- Assist with prioritizing logging activities to meet drilling schedules and project deliverables.
- Ensure geological logging activities are conducted safely and in accordance with company health, safety, environmental, and operational procedures.
- Provide training, mentoring, and technical support to junior geologists and logging personnel as required.
- Support the continuous improvement of geological data collection, interpretation, and management practices across the project.
The above duties and responsibilities represent the nature and level of work assigned and are not necessarily all-inclusive.
Education and Experience
- Bachelor's degree or higher in Geology, Geological Sciences, or a closely related discipline.
- 3–5 years of professional geological experience, preferably within the gold mining, mineral exploration, or resource development industry.
- Demonstrated experience with geological logging of RC, Sonic, and diamond core drillholes.
- Experience overseeing or coordinating geological logging teams and drilling-related geological activities.
- Strong understanding of gold deposit geology, mineralization styles, alteration, lithology, weathering, and structural controls.
- Experience with geological data validation, QA/QC, and maintaining high-quality geological databases.
- Experience working directly with core shed personnel, drilling teams, drilling geologists, and resource/modeling geologists.
- Experience with Acquire geological database and/or logging software.
- Experience using Leapfrog or other 3D geological modeling software preferred but not required.
- Strong understanding of geological logging standards and the importance of consistent data collection for resource modeling and mine planning.
- Strong communication and organizational skills, with the ability to coordinate multiple teams and priorities in a fast-paced drilling environment.
- Ability to identify geological and data-quality issues and work collaboratively to resolve them.
- Ability to work effectively in both field and office/core shed environments.
