Core Responsibilities

Primary Functions

Meticulously collect a diverse range of geological samples, including rock chips, core, soil, and water, ensuring proper labeling, handling, and preservation to maintain sample integrity for laboratory analysis.
Execute detailed geological logging and description of drill core and cuttings, identifying rock types, mineralization, alteration, and structural features with high accuracy.
Operate and maintain a variety of geological and surveying field equipment, such as GPS units, magnetometers, scintillometers, and XRF analyzers, ensuring they are calibrated and functioning correctly.
Conduct on-site field tests, including soil density tests, water quality measurements, and geotechnical assessments, to provide real-time data for project teams.
Diligently record and compile field observations and measurements into digital databases and field notebooks, ensuring data is accurate, complete, and well-organized.
Assist senior geologists and project managers with geological mapping, field traverses, and reconnaissance surveys to identify and delineate geological features and exploration targets.
Prepare geological samples for geochemical and petrographic analysis, which may involve crushing, splitting, pulverizing, and packaging samples according to strict laboratory protocols.
Utilize Geographic Information System (GIS) software, such as ArcGIS or QGIS, to plot sample locations, create geological maps, and visualize spatial data for reports and presentations.
Adhere to and actively promote stringent health, safety, and environmental (HSE) regulations and company policies during all field and lab activities to ensure a safe working environment.
Perform routine maintenance, calibration, and troubleshooting of field and laboratory equipment to minimize downtime and ensure the reliability of collected data.
Compile and draft daily field reports, progress summaries, and data logs to keep project stakeholders informed of on-site activities and findings.
Support the installation, monitoring, and data retrieval from geological and environmental instrumentation, such as piezometers, inclinometers, and weather stations.
Assist in the coordination of field logistics, including scheduling with drilling contractors, organizing site access, and managing the inventory of field supplies and consumables.
Execute quality assurance and quality control (QA/QC) procedures, including the insertion of standards, blanks, and duplicates into sample streams to validate analytical results.
Perform basic geological and structural interpretations of field data under the direct supervision of a professional geologist to contribute to the evolving geological model.
Prepare clear and concise technical charts, cross-sections, and diagrams based on field data to communicate geological concepts to the wider project team.
Conduct pre-fieldwork site reconnaissance to assess accessibility, potential hazards, and logistical requirements for upcoming exploration or sampling programs.
Manage and organize large volumes of physical samples (core, rock chips) in storage facilities, maintaining a logical and accessible inventory system.
Provide hands-on support for geotechnical investigations, including test pit logging, borehole drilling supervision, and in-situ testing.
Digitize historical geological data from paper maps, reports, and logs to integrate it into modern project databases for comprehensive analysis.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to assist geologists with specific research questions.
Contribute to the continuous improvement of the organization's field data collection standards and safety protocols.
Collaborate with business units, such as engineering and environmental teams, to translate project needs into tangible fieldwork requirements.
Participate in regular team meetings, sprint planning, and agile ceremonies within the broader geoscience team.
