Assistant Geologist Jobs in Utah (NOW HIRING)

Resource Geologist – Southern Utah - #4466

We are seeking an experienced Resource Geologist to play a key role in developing, maintaining, and optimizing geological resource models for an active mining operation. This is a high-impact technical role for a geologist who enjoys combining field geology, data analysis, resource estimation, grade control, and mine operations support.

The ideal candidate will bring strong experience in resource modeling, geological interpretation, drill-hole data analysis, QA/QC, grade control modeling, and mine planning software such as Geovia Surpac, Micromine, and/or Leapfrog. This role will support both current operations and future resource development by building accurate models that guide mining decisions, improve ore control, and support long-term mine planning.

This is an excellent opportunity for a hands-on geologist who wants to be closely involved in the full resource cycle — from drilling and data validation to modeling, reconciliation, technical reporting, and operational execution.

Key Responsibilities

Resource Modeling & Estimation

The Resource Geologist will develop and optimize geological resource models using historical and current drilling data, assay results, NI 43-101 reports, ore domains, surface solids, ore solids, structural data, faulting information, core logging, and other relevant geological inputs.

Responsibilities include:

• Conduct resource modeling and resource estimation for existing operations and new projects under evaluation.
• Develop geological models, ore domains, ore solids, surface models, structural models, and fault solids.
• Utilize Geovia Surpac, Micromine, Leapfrog, CAD, and other resource modeling tools to create and maintain geological models.
• Digitize wireframes for ore grades using assay results and geological interpretation.
• Digitize faults, geological formations, surfaces, ore zones, and block models.
• Conduct statistical and geostatistical analysis on assay data to support accurate ore-zone grade estimation.
• Run variogram and statistical analysis in support of QA/QC and resource model requirements.
• Create block models with ore values constrained by statistical analysis, geological features, and wireframes.
• Maintain a strong focus on model reconciliation and investigate changes between resource, reserve, grade control, and mining dig-block models.
• Review historical and current geological data for accuracy, consistency, gaps, and errors.
• Convert historical records, assay results, and geological data from Excel, Access, and other formats into usable formats for modeling software.
• Prepare resource modeling reports, volume estimates, ore percentage reports, and technical summaries for management.
• Recommend improvements to resource modeling processes to enhance quality, consistency, accuracy, and efficiency.
• Work with outside consultants on block modeling and resource estimation as needed.

Grade Control & Mine Operations Support

• Support mine operations through grade-control block model creation and interpretation.
• Ensure geological information from the resource model is accurately carried into grade-control models.
• Assist with wireframing, face mapping, and digital representation of geological features.
• Define and guide appropriate sampling and estimation procedures for mining operations.
• Support core logging, QA/QC standards, drilling standards, sampling standards, and core-management procedures.
• Develop and implement SOPs for resource modeling, QA/QC, drilling, sampling, sample preparation, core handling, and other geological processes.
• Encourage consistency, procedural discipline, and quality controls across technical services and mine operations.
• Train technical services personnel and new employees on Surpac processes, data accuracy, block-model reporting, and resource estimation practices.
• Assist teams in preparing block-model assessments and reporting formats for management.

Technical Analysis & Reporting

• Utilize resource software such as Geovia Surpac, Micromine, and Leapfrog to generate resource and grade-control models.
• Establish systems and standards for resource modeling, QA/QC, drilling, sampling, sample preparation, and geological data management.
• Apply geostatistical analysis and estimation modeling techniques to support accurate resource interpretation.
• Conduct reconciliation validation between resource models, reserve models, grade-control models, and mining dig blocks.
• Prepare detailed technical reports and complete reporting requirements within established timelines.
• Assist with NI 43-101 technical reports, news releases, presentations, and other technical disclosures as required.

Project Management

• Lead and manage drilling programs.
• Prepare wireframes, domain characterizations, ore solids, surface models, and structural interpretations based on drill-hole data, geological mapping, and related site information.
• Coordinate with contractors, consultants, and regulatory bodies to ensure project alignment with company goals, safety standards, and regulatory requirements.
• Participate in feasibility studies, cost estimation, and economic evaluations with a focus on optimizing ore quality and resource value.

Required Qualifications

• Bachelor’s degree in Geology, Geological Engineering, Geoscience, or a related field.
• 5–10 years of experience as a geologist in mining, exploration, or resource development.
• Minimum of 3+ years of experience in resource modeling, preferably with complex sulfide and oxide ore bodies.
• Strong geological interpretation skills with the ability to apply interpretations to resource estimation.
• Experience with Ordinary Kriging and estimation-quality optimization.
• Experience with Resource and Grade Control estimation in mining or exploration.
• Experience with mine planning and resource modeling software such as Geovia Surpac, Micromine, and/or Leapfrog.
• Understanding of database management, QA/QC procedures, drilling practices, sampling practices, and standard laboratory analytical methods.
• Exposure to drill-and-blast design, blasting management, and wall control.
• Knowledge of health, safety, and environmental regulations.
• Contractor management experience.
• Proficiency with Microsoft Word, Excel, PowerPoint, Access, and Outlook.
• Authorized to work in the United States.

Preferred Qualifications

• 5–7 years of dedicated resource modeling experience.
• Professional Geologist certification or eligibility for certification.
• Experience supporting NI 43-101 technical reporting.
• Strong hands-on experience with oxide and sulfide mineral systems.
• Experience supporting active mine operations, grade control, and mine planning teams.

Skills & Competencies

• Strong analytical, technical, and problem-solving skills.
• Excellent attention to detail and commitment to data accuracy.
• Strong written and verbal communication skills.
• Ability to translate complex geological data into clear recommendations for management and operations teams.
• Strong mentoring and training capabilities.
• Ability to collaborate effectively with geology, metallurgy, engineering, technical services, and operations teams.
• Ability to work independently while contributing to a team-oriented mining environment.
• Strong project management and organizational skills.
