CORE MARKER / WRITER (2 Positions)
Reporting relationship
The Core Marker / Writer directly reports to the Site Manager or Deputy Site Manager.
Job summary / overview
The Core Marker / Writer is responsible for accurate labeling, documenting, and handling geological core samples during drilling operations. They use tools like rock saws and core splitters to cut, bag, and tag samples for laboratory analysis while maintaining sample integrity and detailed records. This role ensures geologists can effectively analyze subsurface materials for minerals, metals, and rock formations, supporting informed decisions about project feasibility. Working closely with drilling and geology teams, the Core Writer/Marker ensures compliance with industry standards and company protocols.
Key Responsibilities (Essential Duties and Functions)
Core Handling and Preparation:
- Receive and transport core samples from the drill rig to designated areas.
- Split cores using tools like diamond saws or manual splitters.
- Bag, tag, and organize samples for laboratory analysis.
- Use equipment such as skid steers or pallet jacks to move pallets of core samples.
Marking and Labeling:
- Mark cores with depth intervals, orientation lines, and continuous labels, including full and half-meter measurements.
- Ensure markings are clear, legible, and securely placed to prevent data loss.
Core Drilling and Material Analysis:
- Operate core drilling tools to create precise cuts or extract subsurface materials.
- Assist in evaluating the density, composition, and strength of materials, particularly fine-grained, stone-free soils.
Documentation and Quality Control:
- Log detailed information about core samples, including depth, orientation, and observations, into records or digital systems.
- Maintain sample integrity during handling, storage, and transport.
- Troubleshoot and resolve any sample discrepancies or issues.
Collaboration and Support:
- Work closely with geologists, geo-technicians, and drilling teams on core shack and field activities.
- Provide prepared cores for visual inspection, testing, and advanced analysis.
Health, Safety, and Environmental Compliance:
- Conduct job risk assessments and develop safe work plans.
- Follow safety protocols and perform tasks in a safe, well-managed manner to prevent accidents.
Required Education, Work experience, Qualities and Skills
- No specific degree is mandatory, but knowledge in the following areas Geology, Mining, Environmental Science, Engineering (basic mechanical knowledge) is advantageous.
- At least High School Diploma or equivalent (e.g., GED) or Vocational training or coursework in geology, mining, or a related technical field.
- At least 2 years of experience in similar roles, such as sample / core handling, drilling operations, or working at exploration/mining sites, cutting, or logging, as well as working with geologists or drilling is added value.
- Previous experience is preferred but not necessary as it can come through our training wing.
- Familiarity with core cutting tools (e.g., rock saws, core splitters) and core drilling equipment.
- Basic understanding of geological sampling and recording procedures.
- Knowledge of laboratory sample preparation processes is a plus.
