Job Description:
The Exploration Core Technician in Nice plays a crucial role in the geological evaluation process by managing, processing, and cataloging core samples obtained during exploration drilling. This position ensures that the core retrieved from drilling operations is accurately prepared and documented for analysis by geologists and other technical teams. The technician acts as a bridge between field operations and lab-based geological assessments, providing the foundational data for mine planning and resource estimation.
At the drilling site or core shed, the technician begins by receiving freshly retrieved core samples, checking them for completeness and continuity. The technician carefully lays out the cores in standardized core boxes, aligning them in sequential order to maintain their depth and orientation. Once boxed, the samples are measured, photographed, and logged according to standard protocols. Any irregularities—such as core loss, fracturing, or ground water influence—are noted for further analysis.
Marking and cutting the core samples is another essential responsibility. The technician marks the core for geotechnical testing or geochemical analysis based on geologist instructions. Using precision tools such as rock saws, they cut the core into halves or quarters while ensuring minimal disturbance to its integrity. Samples earmarked for lab submission are labeled clearly, bagged, and sent off according to handling procedures.
In addition to physical processing, the Exploration Core Technician enters all sample data into digital systems, maintaining core logs, box inventories, and sample chains of custody. The technician often assists with initial geological observations, noting rock types, color variations, or visible mineralization that might be of interest to geologists.
Operating within the active mining exploration environment in Nice, the Exploration Core Technician plays a foundational role in transforming raw rock samples into actionable geological data. Their meticulous handling and cataloging practices support resource modeling, structural interpretation, and overall exploration success.
Job Requirement:
The Exploration Core Technician position in Nice requires a strong grasp of core sampling procedures and the ability to process and document geological samples with high precision. The technician must be adept at working in both field and laboratory settings, handling heavy materials, and maintaining systematic records throughout the sampling lifecycle.
An essential requirement is proficiency in core layout and sample organization. The technician must understand depth referencing, core continuity, and the importance of maintaining consistent orientation for structural and lithological analysis. This requires strong spatial awareness and attention to detail, as even small errors in labeling or placement can compromise downstream geological interpretation.
Knowledge of sample preparation techniques, including marking, splitting, and bagging, is critical. The technician must use rock saws and other equipment safely and effectively, wearing protective gear and adhering to standard cutting procedures. They must also follow established protocols for preparing sub-samples for geotechnical tests such as uniaxial compressive strength or point load index testing.
Data handling is another major component of this role. The technician must maintain accurate records using spreadsheets, core logging software, or laboratory information management systems (LIMS). They should be capable of logging measurements, box numbers, depth intervals, and sample IDs with full traceability. Accurate chain-of-custody documentation ensures sample integrity from the field to the lab.
The Exploration Core Technician must also be safety-conscious, particularly when operating saws, handling sharp or heavy rock fragments, or working around moving equipment. They are expected to maintain clean, organized workspaces and comply with site-specific safety protocols, including safe lifting practices and PPE usage.
Collaboration with geologists and drilling personnel is fundamental to the role. The technician must be responsive to instructions, adaptable to evolving sampling plans, and able to communicate observations effectively. In Nice’s dynamic mining environment, this role is integral to building a reliable geological dataset that shapes exploration strategy and future extraction planning.
