What is a grade control geologist?

A Grade Control Geologist is responsible for ensuring the accurate extraction of ore by analyzing and interpreting geological data in a mining operation. They collect and assess drill samples, create geological models, and guide mining teams to maximize ore recovery while minimizing waste. Their work helps improve efficiency, reduce costs, and maintain product quality.

What are the typical daily responsibilities of a grade control geologist within a mining operation?

As a Grade Control Geologist, your typical day involves collecting and analyzing ore and waste samples, supervising drilling activities, validating geological data, and ensuring accurate ore boundary delineation. You’ll work closely with mine planning engineers and production teams to optimize extraction and minimize dilution. Data entry and reporting through specialized geological software are common daily tasks, and you may also be involved in quality assurance and safety checks in the field. This role requires frequent on-site presence, often in active mining environments, and regular communication with other technical staff to support efficient ore recovery.

What are the key skills and qualifications needed to thrive in the grade control geologist position, and why are they important?

To thrive as a Grade Control Geologist, you need a strong background in geology, mineralogy, and mine site sampling techniques, typically supported by a relevant degree in geosciences. Familiarity with mine planning software (such as Surpac or Micromine), GIS tools, and quality assurance protocols is essential, along with understanding industry-specific safety certifications. Strong problem-solving skills, attention to detail, and effective communication are vital soft skills, as this role requires interpreting data and collaborating with mining and engineering teams. These skills ensure accurate ore grade assessment and optimization of extraction processes, directly impacting operational efficiency and profitability.

Job description

Job Type
Full-time
Description
The Resource Geologist will develop and optimize the resource model for both resource and reserve work. The development of the resource model will encompass all of site geological information from past drilling and current drilling data, NI43-01 reports, ore domain, surface solids, ore solids, structures and faulting information, core logging and any relevant geological information that assist in the development of the model. The Resource Geologist will assist with Mine Grade Control modelling to ensure the information from the Resource is carried over into the Grade Control.
Key Responsibilities:
Modelling:
  • Conduct resource modelling and estimation of new projects under evaluation, as well as existing operations;
  • Maintain a strong focus on model reconciliation with an ability to investigate the causes of changes to models and being able to demonstrate the impact on the resulting model;
  • Maintain a strong involvement with the QA/QA function in order to ensure the quality of data supporting the resource models
  • Collecting data from historical records and assay results in Excel and Access
  • Converting data to acceptable formats for digitizing with resource modeling programs such as CAD and Surpac.
  • Review historical data for accurate and consistent information or errors found.
  • Organize data to be clear and easy to follow and find information needed.
  • Performing technical and geological evaluations on historic and current drill hole data.
  • Digitizing wireframes for ore grades using assay results.
  • Digitizing faults and geological formations.
  • Conduct statistical analysis on assay results to determine accurate measurements of the ore zone grades.
  • Digitize block models with ore values limited by statistical analysis, geological features, and wire frames.
  • Create and review reports of volumes and percentages of ore.
  • Report to management estimates and advise management.
  • Recommend updates or changes to the resource modelling processes to improve quality and efficiency and ensure any modifications are consistently implemented and documented;
  • Assist, support and train relevant Technical Services personnel in resource estimation practices;
  • Using Micromine and Surpac to create geological models
  • Develop Surface, ore domains, ore solids and structure or faulting solids for model
  • Run Variogram and Statistical analysis based on QAQC model requirement
  • Consult with consultant on block modelling

Operational Support:
  • Assist mine operations with grade control block model creation.
  • Assist with wireframing and face mapping to ensure the detail of the geological information can be represented digitally.
  • Train new employees on the Surpac process through a series of classes via google meets or in person.
  • Conduct tests of the new employees and be available to assist employees.
  • Train employees to proper process to determine accuracy in the data prior to digitizing.
  • Train employees to report block model assessments and create format to report to management.
  • Encourage consistency and procedure controls
  • Assist with core logging and QAQC standard to be established
  • Develop SOP for resource modelling, QAQC, drilling standard, Sampling standard, and other relevant SOP to standardize
  • Define and guide appropriate sampling and estimation procedures on the mine.

Technical Analysis:
  • Utilize resource software (e.g., Geovia Surpac, Micromine, Leapfrog) to generate resource and grade control models
  • Establish systems and standards to manage resource modelling, QAQC, drilling, sampling preparation, sampling, core management and other geological requirement.
  • Have exposure to geostatistical analysis and estimation modelling technique.
  • Undertake reconciliation validation of the model between resource, reserve, grade control and mining dig blocks

Reporting and Documentation:
  • Prepare and complete all reporting requirements with the appropriate level of details within agreed timeframes.
  • Assist in preparation of Technical Reports (NI 43-101), news releases, presentations and other disclosures as required.

Project Management:
  • Lead and manage drilling programs
  • Prepare wireframing, domain characterization, ore solid generation, surface generation based on drill holes, site geological mapping and other relevant geological data.
  • Coordinate with contractors, consultants, and regulatory bodies to ensure project alignment with company goals and regulations.
